TABLE OF CONTENTS 2 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Executive Summary and Overview Honeywell is pleased to submit an energy savings plan for the Frankford School District in response to the RFP issued in July of 2010. Based on Honeywell’s extensive experience in working with school districts, we are confident that we will be able to deliver a financially viable, comprehensive solution for your buildings that will address existing facility concerns. Our plan will encompass projects that achieve both energy and operational efficiencies and create a more comfortable and safe environment via an actionable Energy Savings Improvement Program (ESIP) in accordance with NJ PL2009, c.4. The Energy Savings Plan is the core of the ESIP process. It describes the energy conservation measures that are planned and the cost calculations that support how the plan will pay for itself in reduced energy costs. Under the law, the Energy Savings Plan (ESP) must address the following elements: The results of the energy audit; A description of the energy conservation measures (ECMs) that will comprise the program; An estimate of greenhouse gas reductions resulting from those energy savings; Identification of all design and compliance issues and identification of who will provide these services; An assessment of risks involved in the successful implementation of the plan; Identify the eligibility for, and costs and revenues associated with the PJM Independent System Operator for demand response and curtail-able service activities; Schedules showing calculations of all costs of implementing the proposed energy conservation measures and the projected energy savings; Maintenance requirements necessary to ensure continued energy savings, and describe how they will be provided; and If developed by an ESCO, a description of, and cost estimates of a proposed energy savings guarantee. It is the intent of this document to provide all the required information for the Frankford School District to determine the next steps in implementing an ESIP throughout the districts’ buildings. The next step is to develop a specific agreement authorizing Honeywell to proceed with an implementation program that meets the requirements of the law and of your RFP. EXECUTIVE SUMMARY AND OVERVIEW 1 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan The ECMs selected by the School District will serve as the basis of that agreement and may be of any combination of projects outlined in this plan so long as they pay for themselves in accordance with PL2009, C.4. Our ESP is organized to clearly define compliance with the law in a structure that provides for an informed decision in selecting ECMs, as well as projecting costs, savings and greenhouse gas reductions. Section A: Independent Energy Audit – This section includes, as reference, the independent energy audit as previously received by the Board in March of 2010. The entire audit is included in Section A, and a comparison can be made of the ECMs outlined in that audit to the additional ECMs described in the overall ESP. The remainder of this section includes a baseline Preliminary Utility Analysis (PUA) which is an overview of the current usage within the District and a cost per square foot by school for utility expenses. This report clearly defines the current expenses for the School District and compares it to the costs of other school districts in the region as a benchmark. Within this benchmarking process, we have identified that the schools have between a 128 and 180 Energy Use Intensity (EUI) rating. This rating indicates where the schools’ energy use compares to the regional mean standard for energy efficiency and consumption. This indicates that there is room for improvement within the plan we have outlined for the District. Section B: Identified Energy Conservation Measures – This section includes a more detailed description of the ECMs we have selected and identified for your District. It is specific by school, scope, savings methodology and environmental impact. It is intended to provide an overview of the projects and not detailed specifications for construction. It identifies ALL potential ECMs for the District for the purposes of inclusion in the program. Final selected ECMs are to be determined by the School District in conjunction with Honeywell during the Project Development Phase of the ESIP process. Section C: Financial Analysis – This section spells out the financial impact of each ECM in simple payback terms without financing costs and in accordance with PL2009, c.4. In addition to the first spreadsheet that outlines ALL ECMs considered, we have identified a SAMPLE recommended project along with a SAMPLE cash flow. We have also included another group of ECM’s as a POTENTIAL projects for your consideration. Ultimately, during the Project Development Phase we will provide you with recommendations and the school district will select the direction of the projects based on your goals and objectives. All ECM’s – This scenario will not meet the requirements of the 15-year term in accordance with PL 2009, C.4. However, it is important to identify these projects within this energy plan for potential implementation at a later date under the current ESIP legislation. EXECUTIVE SUMMARY AND OVERVIEW 2 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Recommended Sample Project – This is an overview of a project that may be accomplished in the School District that will not add additional burden on your tax payers. It can be funded completely through energy and operational savings. When structured financially, the School District will not incur any out of pocket costs and pay for all upgrades from money that is already being spent elsewhere in the District. Over the term of the project, the School District will be in a positive cash flow situation. The School District is well positioned to implement a program that can pay for itself within the requirements of the law while upgrading your facilities with zero impact on your taxpayer base. Section D: Energy Calculations and Greenhouse Gas Reduction Summary – This section includes all the required energy calculations to ensure compliance with the law and to confirm the energy savings can and will be achieved. These calculations are in fact subject to an independent third-party engineering firm review for verification. A summary of all savings include a reduction in 320,728 kWh (kilowatt hours of electricity), 26,954.8 Therms (Gas) and 347.5 Tons of Greenhouse Gas (GHG) emissions. It is the equivalent of removing 60.7 cars from the road for an entire year and is the same as planting 36.6 acres of forest. Section E: M&V/Preventive Maintenance Summary – This section includes all available methods of verification and measurement of calculating energy savings. These methods are compliant with the International Measurement and Verification protocols as well as other protocols previously approved by the Board of Public Utilities in New Jersey. This section also includes the recommended maintenance requirements for each type of equipment that may be included in this program. Consistent maintenance is essential to achieving the energy savings outline in this plan Section F: Design Approach – This section includes a summary of Honeywell’s best practices in the successful implementation of an ESIP project. It provides an overview of our project management procedure, construction management and a sample time frame for the overall completion of the project. Within the sample schedule, we clearly define the stage designated for compliance with architectural, engineering and bidding procedures in accordance to New Jersey Public Contracts Law. We welcome this opportunity to partner with your District in the improved operation and efficiency of your facilities with the successful implementation of this energy savings plan.

(SWA) performed an energy audit and assessment for the Frankford Township School building. The building is located at 2 Pines Rd, Branchville, NJ 07826, in Sussex County. The current conditions and energy-related information were collected in order to analyze and facilitate the implementation of energy conservation measures for the building. The one story Frankford Township School building was originally built in 1950, with additions constructed in 1958, 1968, and 1974. The building houses the Frankford Elementary and Middle School, grades one through eight. The building consists of approximately 90,000 square feet of conditioned spaces. The building includes classrooms, administrative offices, cafeteria, a library, music room, home economics room, a computer lab, an all purpose room, and boiler rooms. The building is occupied on weekdays with 630 students from 8am to 4pm and 105 faculty / staff employees from 6am to 11pm, September through mid-June. The goal of this Local Government Energy Audit (LGEA) is to provide sufficient information to the Frankford Township School Board of Education to make decisions regarding the implementation of the most appropriate and most cost effective energy conservation measures for the Frankford Township School building. Launched in 2008, the LGEA Program provides subsidized energy audits for municipal and local government-owned facilities, including offices, courtrooms, town halls, police and fire stations, sanitation buildings, transportation structures, schools and community centers. The Program will subsidize 75% of the cost of the audit. If the net cost of the installed measures recommended by the audit exceeds the remaining cost of the audit, then that additional 25% will also be paid by the program. The Board of Public Utilities (BPUs) Office of Clean Energy has assigned TRC Energy Services to administer the Program. Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 3/86 EXECUTIVE SUMMARY The energy audit performed by Steven Winter Associates (SWA) encompasses the Frankford Township School building located at 2 Pines Rd, Branchville, NJ 07826. The one story Frankford Township School building was originally built in 1950, with additions constructed in 1958, 1968, and 1974. The building consists of approximately 90,000 square feet of conditioned spaces. The building includes both the elementary and middle school. Based on the field visits performed by the SWA staff on February 11th and the results of a comprehensive energy analysis, this report describes the site’s current conditions and recommendations for improvements. Suggestions for measures related to energy conservation and improved comfort are provided in the scope of work. Energy and resource savings are estimated for each measure that results in a reduction of heating and cooling energy use. From April 2008 to March 2009 the Frankford Township School building consumed 590,800 kWh or $98,277 worth of electricity at an approximate rate of $0.166/kWh and 41,458 gallons (58,041 therms) or $86,354 worth of fuel oil #2 at an approximate rate of $2.083/gallon ($1.488/therm). The joint energy consumption for the building, including both electricity and fuel oil #2, was 7,820MMBtu of energy that cost a total of $184,631. SWA has entered energy information about the Frankford Township School building in the U.S. Environmental Protection Agency’s (EPA) Energy Star Portfolio Manager Energy benchmarking system. The building received a score of 59 when compared to similar school buildings. Buildings achieving an Energy Star rating of 75 are eligible to apply for the Energy Star award and receive the Energy Star plaque to convey superior performance. These ratings also greatly help when applying for Leadership in Energy and Environmental Design (LEED) building certification through the United States Green Building Council (USGBC). SWA encourages the Board of Education to continue entering utility data in Energy Star Portfolio Manager in order to track weather normalized source energy use over time. The Site Energy Use Intensity is 86.0 kBtu/ft2yr compared to the national average of a school building consuming 94.0 kBtu/ft2yr. Implementing the recommendations included in this report will reduce the building energy consumption by approximately 14.5 kBtu/ft2yr. There may be energy procurement opportunities for the Frankford Township School to reduce annual utility costs, which are $6,703 higher, when compared to the average estimated NJ commercial utility rates. Based on the assessment of the Frankford Township School building, SWA has separated the recommendations into three categories (See Section 4 for more details). These are summarized as follows: Category I Recommendations: Capital Improvement Measures • • • • • • • • Insulate exterior walls Replace wood doors in classrooms Replace 1972 roof section Replace single pane windows Upgrade building per ADA requirements Replace unit ventilators Replace (2) H&V units serving the Large Gym and Multipurpose Room Replace (1) H&V units serving the Small Gym Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 4/86 • • • • • • • • • • • In lieu of DX cooling systems recommended above, add chilled water cooling system In lieu of DX cooling systems recommended above, add conventional water source heat pumps In lieu of chilled water or DX cooling systems recommended above, add geothermal cooling and heating system Upgrade Building Management System (BMS) Replace common area heating equipment Replace window air conditioners Upgrade electric service Provide code minimum ventilation air to all rooms lacking adequate ventilation Consider replacement of the 1968 Bally walk-in cooler/freezer Consider replacement of the reach-in milk cooler in cafeteria Install premium motors when replacements are required Category II Recommendations: Operations and Maintenance • • • • • • • • • • Correctly install fiberglass batt attic insulation (air seal prior to installation) Inspect and replace gasketing around door into the walk-in refrigeration boxes in the Kitchen and outside. Water levels in the expansion tanks and the integrity of the tank bladder should be checked to confirm proper operation. Use Energy Star labeled appliances Maintain roofs Maintain downspouts Provide weather stripping / air sealing Preventative exterior wall maintenance Use smart power electric strips Create an energy educational program Category III Recommendations: Energy Conservation Measures - Upgrades with associated energy savings At this time, SWA highly recommends a total of 8 Energy Conservation Measures (ECMs) for the Frankford Township School building that are summarized in Table 1. The total investment cost for these ECMs is $23,977. SWA estimates a first year savings of $9,188 with a simple payback of 2.6 years. SWA estimates that implementing the highly recommended ECMs will reduce the carbon footprint of the Frankford Township School building by 76,353 lbs of CO 2 , which is equivalent to removing approximately 6 cars from the roads each year or avoiding the need of 186 trees to absorb the annual CO 2 generated. SWA also recommends 3 ECMs with payback greater than 5 years summarized in table 2, which result in a first year savings of $905. SWA also recommends 7 Over 10 year Payback and End of Life Cycle ECMs with a total first year savings of $33,295 that are summarized in Table 3. Institutional buildings with an average annual peak demand over 200 kW (Frankford Township School peak demand is about 206 kW) are eligible to participate in the NJ Clean Energy Pay for Performance program. Incentives for electricity and fuel oil #2 savings will be paid based on actual savings, provided that the minimum performance threshold of 15% savings has been achieved. To participate, select a Program Partner from an approved partner list and submit Application Package Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 5/86 with your Partner's assistance. Reducing 15% of the energy use at Frankford Township School will be challenging without undertaking significant investment. There are various incentives that Township of Lower could apply for that could also help lower the cost of installing the ECMs. SWA recommends that the Frankford Township School apply for the NJ SmartStart program through the New Jersey Office of Clean Energy. This incentive can help provide technical assistance for the building in the implementation phase of any energy conservation project. A new NJ Clean Power program, Direct Install, could also assist to cover 80% of the capital investment. SWA strongly encourages that the Frankford Township School proceeds to move forward with the Direct Install program in order to offset the cost of the recommended lighting measures. Renewable ECMs require application approval and negotiations with the utility and proof of performance. There is also a utility-sponsored loan program through JCP&L that would allow the building to pay for the installation of the PV system through a loan issued by the utility. The following tables summarize the proposed Energy Conservation Measures (ECMs) and their economic relevance. In order to clearly present the overall energy opportunities for the building and ease the decision and choice of which ECM to implement, SWA calculated each ECM independently and did not incorporate slight/potential overlaps between some of the summarized ECMs (i.e. lighting change influence on heating/cooling).

Utility rate The Frankford Township School building currently purchases electricity from its utility at a general service market rate for electricity use (kWh) with a separate (kW) demand charge. The Frankford Township School building currently pays an average rate of approximately $0.166/kWh based on the 12 months of utility bills of April 2008 to March 2009. The Frankford Township School building currently purchases fuel oil #2 supplied by Finch Fuel Oil at the prevailing market rates for fuel oil #2. The average aggregated rate (supply and transport) for the oil is approximately $2.083/gallon ($1.48/therm) based on 12 months of fuel oil bills for April 2008 to March 2009. 1.3. Energy benchmarking SWA has entered energy information about the Frankford Township School building in the U.S. Environmental Protection Agency’s (EPA) Energy Star Portfolio Manager Energy benchmarking system. The building received a score of 59 when compared to other school buildings of its kind. Buildings achieving an Energy Star rating of 75 or higher, and professionally verified to meet current indoor environmental standards, are eligible to apply for the Energy Star award and receive the Energy Star plaque that conveys superior energy performance to students, parents, taxpayers, and employees. These ratings also greatly help when applying for Leadership in Energy and Environmental Design (LEED) building certification to the United States Green Building Council (USGBC). Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 14/86 The Site Energy Use Intensity is 86.0 kBtu/sqft compared to the national average intensity of school buildings consuming 94.0 kBtu/sqft. Implementing this report’s highly recommended Energy Conservations Measures (ECMs) will reduce use by approximately 2.0 kBtu/sqft with an additional 12.5 kBtu/sqft from the other recommended measures. Additionally, the building can offset 6.1 kBtu/sqft from installing a 151.2 kW PV rooftop system. These recommendations could account for at least 20.6 kBtu/sq ft yr reduction, which when implemented would make the building energy consumption even lower. SWA has created the Portfolio Manager site information for Frankford Township School Board of Education. Access is also allowed to TRC.

FACILITY AND SYSTEMS DESCRIPTION 2.1. Building Characteristics The one story Frankford Township School building was originally built in 1950, with additions constructed in 1958, 1968, and 1974. The building consists of approximately 90,000 square feet of conditioned spaces. The building includes classrooms, administrative offices, cafeteria, a library, music room, home economics room, a computer lab, an all purpose room, and boiler rooms. 2.2. Building occupancy profiles The building houses the Frankford Elementary and Middle School, grades one through eight. The building is occupied on weekdays with 630 students from 8am to 4pm and 105 faculty / staff employees. The building remains unoccupied over the weekend. There is a scheduled two-week summer program that runs irregularly. 2.3. Building envelope 2.3.1. Exterior Walls The exterior wall assemblies consist of a brick veneer (with EIFS above certain windows), aluminum framed window wall panels with certain sections containing 2x6 wood framed walls or with CMU (Concrete Masonry Unit) walls. Interior wall finishes are a mixture of lath and plaster, tile, painted CMU and gypsum wall board. During the next major renovation, SWA recommends insulating the exterior walls to the current local building code by adhering 2” polyiso boards (Polyisocyanurate) together with furring strips and gypsum wall boards to the inside of the painted CMU walls. Exterior wall assembly (portion of Elementary School) Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 17/86 Exterior wall assembly types Water damage EIFS Interior wall finish – lath and plaster wall damage Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 18/86 Overall the exterior wall assemblies of the building appear to be in excellent condition with no major issues of concern. There were no additional areas of concern mentioned to SWA at the time of the building audit. SWA recommends regular maintenance to exterior walls, repointing brick veneer, caulking around windows or doors, and removing all damage due to insects or rodents. Attention and maintenance should be given to these areas as uncontrolled roof water runoff can potentially penetrate exterior walls and cause energy losses and structural damage. Special attention should be given to roof drainage to avoid water damage to exterior wall assemblies. 2.3.2. Roof The Frankford Township School roof sections were upgraded in 1996 (pitched asphalt roof section,) in 2001 for EPDM roof section (over classrooms & gymnasium), 1972 for the EPDM roof section over the kitchen, small gym and classrooms and the 2009 EPDM roof section was installed over the music rooms, science lab, and computer lab. At the time of the audit SWA was not able to access the roof due to snow and safety concerns. SWA auditors were told that in-house maintenance personnel perform regular maintenance on all roof sections. Also, SWA was told that during the 2009 roof upgrade additional sealing seams and re-tarring was done around the perimeter of the building. A full set of building drawings was not available to confirm insulation levels for the flat roof sections of the building. The pitched roof section of the building contains approximately 12” of faced fiberglass batts haphazardly placed on the attic floor. This area contains sufficient insulation although SWA recommends installing the fiberglass batts evenly both between the ceiling joists and across the ceiling joists. In order for insulation to perform effectively an air barrier should be installed and in constant and even contact with the insulation. As seen in infrared images below there is considerable heat loss of expensive conditioned air due to penetrations from areas below and from inconsistent insulation. Before removing and installing insulation properly SWA suggests air sealing all penetrations including top-plates, plumbing, HVAC ductwork, electrical penetrations, etc, with (fire-rated) caulk or foam. Improvements such as these may offer further comfort benefits and help to reduce energy loss. Fiberglass insulation haphazardly displaced Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 19/86 Infrared images showing heat loss with missing batt insulation and haphazard installation Image showing damaged ceiling tiles in classroom At the time of the audit, SWA was told there are no roof leaks or roof maintenance issues. Damaged ceiling tiles should be checked and replaced in concern for indoor air quality. Regular maintenance should be performed to prevent potential damage to the integrity of the roofing system. When it is time for roof replacement (considering the 1972 roof section), SWA recommends an Energy Star certified roof membrane and rigid insulation (3”) assembly. 2.3.3. Base There is a CMU walled tunnel under the Elementary School portion of the building with uninsulated walls (under the A wing of the building). According to building staff the purpose of the design was for under-floor hot air flow, but it is no longer used. The rest of the building’s base is an uninsulated 4” concrete slab-on grade with a perimeter footing and concrete block stem walls. At the time of the audit snow was melting off the roof and water was pooling in certain areas due to either insufficient grading and/or the downspouts not extending far enough from the base of the building. SWA recommends extending downspouts, installing french drains, or connecting downspouts underground storm water system. No water seepage through the slab or other issues related to thermal performance was detected. Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 20/86 Water pooling at base of building due to extreme weather condition 2.3.4. Windows The windows of the school building are single pane, aluminum framed windows and appear to be in fair condition. The seals of the windows are ineffective and do not provide an air tight seal from exterior conditions, increasing the loss of expensive conditioned air. The windows are non-thermal break single glazed with un-insulated panels above them and are energy inefficient. SWA recommends replacement of the single pane windows as part of capital improvement and suggests replacing the existing windows with double-glazed thermal break low-E aluminum framed units. Regular maintenance should be performed, recaulking around the perimeter of windows (exterior and interior) to ensure a tight seal. Open window on day of audit, approximately 28°F Additionally window AC units should be removed for winter conditions. If removal of these units is not feasible, SWA recommends airtight covers such as Chill Stop-R or a gasketed cover for optimum performance. Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 21/86 Single pane aluminum framed windows 2.3.5. Exterior doors At the time of the audit SWA was told all main exterior doors were replaced in 2000. The FRP exterior doors were inspected and observed to be in very good condition. The exterior wood doors found in various classrooms are in need of replacement. Bubbling of paint (seen in the image below) may lead to rot or warping of the door. Older exterior wood door (serving as exit from classroom) SWA recommends checking the weather-stripping of each door on a regular basis and replacing any broken seals. Tight seals around doors will help ensure the building to be is kept continuously insulated. When exterior doors or garage doors warrant replacement SWA recommends upgrading existing doors with doors containing a higher R-value with effective seals. Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 22/86 Exterior types of doors all requiring maintenance to verify air tight seals 2.3.6. Building air tightness In addition to the above mentioned recommendations SWA suggests air sealing, caulking and / or insulating around all plumbing, electrical, HVAC and structural envelope penetrations. This should include bottom and top plates, recessed light fixtures, electrical boxes, chimney walls and window, or sleeve air conditioner units. If units cannot be removed SWA recommends Chill Stop-R or similar tight sealing gasketed cover to prevent loss of expensive conditioned air. Window air conditioner units left in winter conditions; Infrared image showing loss of heated air around perimeter of unit (also aluminum windows frames heated by sun) PVC pipe entering building should be sealed with foam or caulk Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 23/86 2.4. HVAC Systems Frankford Township School is primarily heated by hot water, but there are also some small offices where the A wing and B wing meet that are heated by electric baseboard heaters. Hot water is provided by two heating plants, each housed in a separate boiler room. One plant contains two (2) boilers that heat the A wing and B wing, and one plant has one boiler that serves the C wing and D wing. There is no natural gas service to the building and no utility natural gas mains nearby available for connection. Boilers are served by number 2 fuel oil from an underground storage tank located outside the B wing. The A wing was originally built in 1950 and renovated in 1988. The B wing was added in 1958, the C wing was added in 1968 and the D wing was added in 1974. 2.4.1 Heating The classrooms in the A wing contain hot water terminal units in the form of ceiling-mounted unit ventilators. In addition, the Media Center and the Art Room both contain two (2) ceilingmounted unit ventilators and each of the Elementary School offices each contain a ceilingmounted unit ventilator (six (6) total offices).This equipment was installed as part of a 1988 renovation to this wing of the building. These unit ventilators are in good condition and appear to be operating. The classrooms in the remaining wings contain wall mounted unit ventilators. It appears that all of the original unit ventilators from the 1958, 1968 and 1974 construction of these wings are still present in the building. This equipment is in fair to poor condition. In total, the school contains approximately sixty (60) Nesbitt unit ventilators of varying ages. Unit Ventilators in B Wing (Left) and C Wing (Right) The building also contains enclosed wall mounted and ceiling mounted finned tube radiation in the corridors, vestibules, toilet rooms and in the Middle School offices. Each unit ventilator contains a heating coil, fan assembly, damper, filter and controls within a metal cabinet. Equipment was designed to introduce outdoor air via a grille and damper located on the outside wall. The units are designed to mix room air with outside air, heat the air as required, and deliver the air to the occupied space. The older wall mounted unit ventilators deliver the air directly through a grille on the top of the unit. The air from the ceiling-mounted units is discharged through a grille on the front face of the unit directly into the room. Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 24/86 The Large Gymnasium, which also serves as the Cafeteria and Multipurpose Room, is heated by two (2) heating and ventilating (H&V) units, with fresh air provided via rooftop vents. There is one vertical unit located in a small room adjacent to the kitchen. The second unit is horizontal type and is mounted above the Stage. The Small Gym is heated by a large H&V unit suspended from the roof with fresh air provided through a wall louver. H&V Unit Suspended From Roof in Small Gym The Kitchen Storage room that contains the walk-in cooler/freezer is heated by a hot water H&V unit located above the Middle School Copy Room, with fresh air provided via a rooftop vent. The Boy’s and Girl’s Locker Rooms are heated via hot water cabinet unit heaters suspended from the ceiling. The Occupational Therapy, Speech and Child Study Team offices, which are located where the A wing and B wing meet, are heated by electric baseboard heaters. The offices also have curtain walls and single pane windows, and it was reported by the staff in these offices that the electric baseboard heaters run constantly during the heating season. These rooms are in close proximity to the A/B wing boiler room, and replacing these electric baseboard units with hot water unit ventilators, along with providing insulated walls and windows, would yield savings in energy and operating costs. The heating hot water for the A wing and B wing is produced by two (2) oil-fired hot water boilers located in the A/B boiler room. There are two (2) sets of floor-mounted hot water pumps that distribute the heating water out to the two wings. These pumps operate in leadlag fashion, so only one of each pair is operating at one time. This hot water heating system is piped in a primary pumping arrangement. The boilers have a capacity of 2,247 MBH and 2,403 MBH respectively. The boilers are cast iron sectional type. One boiler was installed in 1986 and the other boiler was installed in 1992. According to their age, the boilers have about 6 years and 11 years respectively remaining on their expected service life of 30 years, as published in the 2007 ASHRAE HVAC Applications Handbook. The burners were installed in 1986 and 1992 respectively, and are fed from a 10,000 gallon underground oil storage tank that is adjacent to the B Wing. The first burner is beyond its expected service life and the second burner is approaching its expected service life of 21 years, as published in the 2007 ASHRAE HVAC Applications Handbook. Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 25/86 Energy savings could be achieved by replacing these boilers with higher efficiency packaged oil-fired boilers with burner modulation, but this upgrade cannot be justified by energy savings alone. A/B wing boilers It is assumed that the circulating pumps were installed in 1986 and 1992 when each boiler was replaced. SWA recommends that the pump motors are replaced with premium efficiency motors. The heating hot water for the C and D wings is produced by one (1) hot water boiler located in the C/D wing boiler room. There are two (2) sets of hot water pumps that distribute the heating water out to the two wings. One set is floor-mounted and one set is pipe-mounted. These pumps operate in lead-lag fashion, so only one of each pair is operating at one time. This hot water heating system is piped in a primary pumping arrangement. The boiler has a capacity of 3,330 MBH. The boiler was reportedly installed in 1992. According to its age, the boiler has about 12 years remaining on their expected service life of 30 years, as published in the 2007 ASHRAE HVAC Applications Handbook. The burner is approaching its expected service life of 21 years, as published in the 2007 ASHRAE HVAC Applications Handbook. Energy savings could be achieved by replacing this boiler with a higher efficiency packaged oil-fired boiler with burner modulation, but this upgrade cannot be justified by energy savings alone. C/D wing boiler Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 26/86 It is assumed that the circulating pumps were installed in 1992 when the boiler was replaced. SWA recommends that the pump motors are replaced with premium efficiency motors. Pneumatic Control System Panel in C/D Wing Boiler Room The building contains two (2) pneumatic controls systems to control the equipment in each pair of wings. The air compressors were noted to run often and in several instances, the thermostats were observed to make a hissing noise indicative of leaking compressed air. There were no complaints about the ability of the heating system to provide adequate heat to the building occupants. It was reported that the thermostats provide little to no control over the heating equipment and that most areas experience overheating during the heating season. This is leading to excessive operation of the boilers. In addition, it was reported that the fans for several of the unit ventilators and the exhaust fans for the gyms run during unoccupied hours. The expected service life of a pneumatic controls system is 20 years per 2007 ASHRAE HVAC Applications Handbook. Based on these facts, SWA recommends that the pneumatic controls system be replaced with an electronic DDC controls system for all of the equipment in the building. 2.4.2 Cooling The majority of the cooling is in the form of 1-2 ton window air conditioning units in several classrooms and offices, totaling about 20 in all. Most of these units are not Energy Star rated. The TV Studio and adjacent offices are cooled by a packaged DX cooling only HVAC unit mounted on grade beside the entrance to the Middle School. The equipment is about 15 years old and is therefore at the end of its expected service life of 15 years per 2007 ASHRAE HVAC Applications Handbook. The unit appeared to be in fair condition. It should be noted that Room 54 in the D-Wing contains 20 computers and no mechanical cooling system. SWA recommends that either window air conditioning or a ductless DX split system is provided for this room due to the expected high heat load from the computers. Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 27/86 Packaged HVAC Unit on Grade Serving TV Studio 2.4.3 Ventilation As mentioned above, the grilles on the Nesbitt unit ventilators provide fresh air to the classrooms and the Art Room and Library in the A-Wing. SWA recommends that this equipment be replaced as part of a capital improvement, and that the new equipment provided with a means of providing a code compliant level of outside air to the spaces. The Large Gymnasium, which also serves as the Cafeteria and Multipurpose Room, is ventilated by two (2) heating and ventilating (H&V) units, with fresh air provided via rooftop vents. There is one vertical unit located in a small room adjacent to the kitchen. The second unit is horizontal type and is mounted above the Stage. The Small Gym is ventilated by a large H&V unit suspended from the roof with fresh air provided through a wall louver. The Kitchen Storage room that contains the walk-in cooler/freezer is ventilated by a hot water H&V unit located above the Middle School Copy Room, with fresh air provided via a rooftop vent. The Boy’s and Girl’s Locker Rooms are ventilated via rooftop exhaust fans with makeup air provided from the Multipurpose Room H&V unit. The kitchen contains a commercial cooking exhaust hood with corresponding rooftop exhaust fans. There is no dedicated makeup air unit so the makeup air is provided the H&V units that serve the Large Gymnasium, Cafeteria and Multipurpose Room. It appears that the following rooms are not provided with code minimum ventilation air: Elementary Guidance Office (A-Wing), Elementary Janitor’s Closet (A-Wing), Nurse’s Office (A-Wing), OT/Speech/Child Study Team Offices (A-Wing), Middle School Guidance Office and adjacent Room P1(D-Wing), Middle School Copy Room (D-Wing) . This condition must be addressed during the capital improvement work recommended herein. The building has a number of exhaust fans on the roof above the corridors, toilet rooms and classrooms of the B, C and D Wings. These fans are original to the respective wings and are beyond their expected service life. There is a pitched roof with attic space above the A Wing, and the classrooms, Art Room and Library are provided with attic-mounted exhaust fans ducted to a wall grille to relieve the fresh air intake and aid in the overall ventilation of these spaces. The toilet rooms are also exhausted via attic-mounted fans. The fans in the Awing are 22 years old and are beyond their expected service life of 20 years based on the Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 28/86 2007 ASHRAE HVAC Applications Handbook. SWA recommends that this equipment is replaced as part of a capital improvement project, and that it is designed to provide code minimum ventilation rates. Typical Rooftop Exhaust Fan 2.4.4 Domestic Hot Water The hot water boilers produce the domestic hot water for the majority of the school. Boiler #2 in the A/B Boiler Room contains two (2) tankless water heater sections that provide domestic hot water for the A and B wings of the school. The Boiler in the C/D Boiler Room contains multiple tankless heater sections that provide domestic hot water for the C and D Wings of the school. Both systems incorporate a hot water recirculating pump. Due to this method of providing domestic hot water, the boilers must be fired even during mild weather when there would normally be no space heating load. SWA recommends providing separate tank-type domestic water heaters to handle the domestic water heating load. This will provide energy savings by allowing the school to not fire the boilers during mild weather. There is also one (1) electric tank type domestic water heater located in the PTA storage room in the D Wing, presumably serving the toilet rooms in that wing. Replacement would not yield significant energy savings but should be considered due to age. Typical Tankless Boiler Immersion Domestic Water Heater in A/B Boiler Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 29/86 Updated bathrooms with sensors for toilets and sinks (with 0.5gpm aerators) 2.4.5 Commercial Kitchen Equipment There is one (1) walk-in cooler/freezer at the rear of the kitchen. This equipment was installed with the construction of the C Wing in 1968 and is in fair condition. The rooftop compressors have been replaced in recent years and are fairly efficient. The cooler was labeled as using R-22 refrigerant and the freezer uses R-502 refrigerant. The evaporator fans are original to the cooler and freezer and the Frankford School could realize some energy savings by replacing these fans with more energy efficient fans. There is also one (1) walk-in freezer located outside the building, adjacent to the D-Wing. This freezer is much newer than the interior unit and utilizes fractional horsepower evaporator fans. This freezer is in very good condition and utilizes R-404a refrigerant. There is one (1) 6-door stainless steel electric reach-in commercial refrigeration unit located in the kitchen that utilizes R-12 refrigerant. It is estimated that this equipment was installed in 1976 and is in relatively good condition. However, SWA recommends that the unit is replaced based on potential energy savings and the fact that R-12 is listed by the EPA as an ozone-depleting substance and production of this refrigerant was banned by the Clean Air Act in 1996. The kitchen also contains one (1) reach-in milk cooler that also uses R-401a as its refrigerant. There was no accessible nameplate found during our survey, but it is estimated that this equipment was installed with the 1976 addition, and it is in fair condition. In addition to the kitchen equipment, there are two (2) residential style refrigerators in the Home Economics classroom, and one in the B Wing Faculty Lounge, and in the Middle School Copy Room. None of the refrigerators were noted to be Energy Star rated. The kitchen also contains several pieces of commercial-style cooking equipment, including (2) electric convection ovens and (2) electric range/ovens. There is a large kitchen hood provided for this equipment. The Kitchen also contains a tall electric heated storage cabinet. The makeup air is likely provided via transfer from the adjacent Cafeteria H&V units. Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 30/86 2.5. Electrical systems 2.5.1. Lighting Interior Lighting - The Frankford Township School building currently consists of mostly older inefficient T12 bulbs with magnetic ballasts. SWA recommends upgrading to high performance T8 fluorescent fixtures with electronic ballasts. There are also fixtures found to contain incandescent bulbs (as seen in the image below). SWA recommends upgrading these fixtures with compact fluorescent bulbs. Based on measurements of lighting levels for each space, there are not any vastly over-illuminated areas. SWA recommends installing occupancy sensors in classrooms, closets, offices and areas where payback on savings is justified. Typically, occupancy sensors have an adjustable time delay that shuts down the lights automatically if no motion or sound is detected within a set time period. See attached lighting schedule in Appendix A for a complete inventory of lighting throughout the building and estimated power consumption. Incandescent bulbs in faculty lounge bathroom Exit Lights - Exit signs were found to be LED type. Exterior Lighting - The exterior lighting surveyed during the building audit was found to be a mix of CFLs and Metal Halide fixtures. Some of the exterior lighting is controlled by photocell sensors. SWA is recommending photocell sensors for all exterior lighting or timers. Exterior lights left on during daylight hours Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 31/86 2.5.2. Appliances and process Appliances, such as refrigerators, that are over 10 years of age should be replaced with newer efficient models with the Energy Star label. For example, Energy Star refrigerators use as little as 315 kWh / yr. When compared to the average electrical consumption of older equipment, Energy Star equipment results in a large savings. Building management should select Energy Star label appliances and equipment when replacing: refrigerators, printers, computers, copy machines, etc. More information can be found in the “Products” section of the Energy Star website at: http://www.energystar.gov. SWA recommends consulting with the vendor that supplies all vending machines, requesting Energy Star models when the contract is due for renewal. Also, energy vending miser devices are now available for conserving energy usage by Drinks and Snacks vending machines. When equipped with the vending miser devices, vending machines use less energy and are comparable in daily energy performance to new ENERGY STAR qualified machines. Two vending machines in Cafeteria, one vending machine in faculty lounge SWA also recommends removal of all unnecessary appliances throughout the school. Small personal refrigerators, additional microwaves, or other appliances add to the school electrical load. Computers left on in the building consume a lot of energy. A typical desk top computer uses 65 to 250 watts and uses the same amount of energy when the screen saver is left on. Televisions in meeting areas use approximately 3-5 watts of electricity when turned off. SWA recommends all computers and all appliances (i.e. coffee makers, televisions, etc) be plugged in to power strips and turned off each evening just as the lights are turned off. Smartboards & Computers left on in vacant classrooms Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 32/86 2.5.3. Elevators The Frankford School is a single story building and there is no elevator. 2.5.4. Emergency Generator There is one (1) 150KW diesel emergency generator on site.

Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 36/86 4. ENERGY CONSERVATION MEASURES Based on the assessment of the Frankford Township School builidng, SWA has separated the investment opportunities into three recommended categories: 1. Capital Improvements - Upgrades not directly associated with energy savings 2. Operations and Maintenance - Low Cost / No Cost Measures 3. Energy Conservation Measures - Higher cost upgrades with associated energy savings Category I Recommendations: Capital Improvements • Insulate exterior walls - SWA recommends insulating the exterior walls of at least the original structure by adhering 2” polyiso boards (Polyisocyanurate) together with furring strips and gypsum wall boards to the inside of the painted CMU walls. • Replace wood doors in classrooms with insulated FRP gasketed exterior doors. Investigate R values of doors for improved energy conservation. • Replace 1972 roof section – Due to age and end of life condition, SWA recommends replacement of the 38 year old single-ply EPDM roof sections with an Energy Star certified membrane and insulation (3” rigid) assembly. Maintenance should be performed at regular intervals with a roofing contractor to prevent future roof leaks or to prevent future damages to the roof assembly. It is also advisable to upgrade any questionable roof integrity areas before photovoltaics are installed, as any repairs after the system is installed will be costly. • Replace windows - SWA evaluated, as part of a capital improvement plan, replacing all single-pane windows (approximately 2407 sq ft) with newer models with thermal breaks, dual glazing and a low-e rating. A licensed contractor should assess and calculate accurate window areas and rough openings for replacement. Proper flashing and caulking should be performed upon installation of the new windows. The building contains approximately 2407 square feet of single-pane fixed and casement aluminum-framed windows with single-glazing. In context of other energy measures proposed in this report and in an effort to maximize the cost-benefit factor for improvements, SWA recommends that these windows be replaced with the next major capital improvement / renovation project. Windows considered for replacement should have the following outline specifications besides conforming to local code and regulations: the windows shall be aluminum frame thermally manufactured as double hung commercial type modules. The clear, low-e, argon filled dual glazing should be 2 independent panes. The walls should be extruded aluminum with integral poured-in-place thermal barrier. All horizontal rails should be of tubular shape and joinery should be butted and coped with stainless steel screws. Air infiltration shall not exceed 0.10 cfm/sf of unit. The conductive thermal transmittance (UValue) shall not be more than 0.51 Btu/hr sq ft °F. Upgrade building per ADA requirements SWA recommends that the Frankford Township School Board of Education do as much as possible to comply with the latest ADA regulations. • Replace unit ventilators - Replace 60 Nesbitt unit ventilators originally installed when the respective wing was constructed (7 in 1958 B Wing, 9 in 1968 C Wing and 18 in 1974 D Wing) except the (26) A Wing units which were replaced in 1988. The B, C and D Wing units are well beyond their expected service life. The A Wing units are also beyond their expected Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 37/86 service life by a few years. Considering the increased maintenance repair costs and that replacement parts are difficult to find, SWA recommends replacement of this equipment. There is better control offered by the newer, electronically controlled units, although energy savings are negligible. Typical specifications for the new units can be as follows: “The fans should be double inlet forward curved of centrifugal variety; have a maximum speed of 1,000 rpm with permanent split capacitor motors. The fan housing should be constructed of heavy gauge metal to help reduce air noise during operation. Wheel motors are to be premium efficiency, single speed, and permanent split capacitor with overload protection. Each fan should be equipped with a three speed switch for air balancing. An ultra-low leak, blade type outside air damper will ensure low leakage of the outside air when the equipment is not operating. The unit shall have a solid-state defrost control system and two separate filters. The air-to-air heat exchanger should be designed to support two air streams in a counter-flow direction. The heat exchanger matrix shall permit less than one percent of cross contamination between the air streams. The heat exchanger shall have an effectiveness of approximately 80% with equal airflow.” Energy savings from the proposed units do not justify the economics for replacement, and is hence recommended as capital improvement. The estimated cost of 60 new fan coil ventilators is $575,000. • The Frankford Township School may wish to consider adding DX cooling as part of the equipment replacement. In this case, it should be recognized that cooling will result in an increase in energy usage versus providing heating and ventilation only. The estimated budget installed cost for DX coil and air cooled condensing units for the unit ventilators is an additional $220,000. Note that the addition of air conditioning may require an upgrade to the existing electric service. The cost of the electric service upgrade is broken out separately below but should be included if the cooling option above is incorporated. • Replace (2) H&V units serving the Large Gym and Multipurpose Room - The hot water heating only ventilation system for the Large Gym and Multipurpose Room is beyond its expected service life. SWA recommends that this equipment is replaced as part of a capital improvement project, and that it is designed to provide code minimum ventilation rates. The estimated budget installed cost for (2) hot water H&V units for the Large Gym and Multipurpose Room is $95,000.The Frankford Township School may wish to consider providing DX cooling as part of this system to make the room more functional in warm weather, but should recognize that this will increase energy usage versus providing a heating and ventilation system only. If cooling is desired, it is strongly recommended that a system is provided that utilizes a heat recovery wheel for pretreatment of the outside air and CO2 sensors for demand control ventilation. This is a replacement in kind recommendation which offers negligible energy savings. The estimated budget installed cost for (2) rooftop H&V units with DX cooling and heat recovery wheel is $140,000. Note that the addition of air conditioning may require an upgrade to the existing electric service. The cost of the electric service upgrade is broken out separately below but should be included if the cooling option above is incorporated. • Replace (1) H&V units serving the Small Gym - The hot water heating only ventilation system for the Small Gym is beyond its expected service life. SWA recommends that this equipment is replaced as part of a capital improvement project, and that it is designed to provide code minimum ventilation rates. The estimated budget installed cost for (1) hot water H&V units for the Small Gym is $45,000.The Frankford Township School may wish to Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 38/86 consider providing DX cooling as part of this system to make the room more functional in warm weather, but should recognize that this will increase energy usage versus providing a heating and ventilation system only. If cooling is desired, it is strongly recommended that a system is provided that utilizes a heat recovery wheel for pretreatment of the outside air and CO2 sensors for demand control ventilation. These additional features may require rooftop equipment with side discharge ductwork that would be ducted through the current outside air louver opening, which would involve some residual architectural and/or structural work. This is a replacement in kind recommendation which offers negligible energy savings. The estimated budget installed cost for (1) rooftop H&V unit with DX cooling and heat recovery wheel is $80,000. Note that the addition of air conditioning may require an upgrade to the existing electric service. The cost of the electric service upgrade is broken out separately below but should be included if the cooling option above is incorporated. • In lieu of DX cooling systems recommended above, add chilled water cooling system along with unit ventilator and H&V unit upgrades -- The estimated budget installed cost for the addition of a chiller, pumps, piping and required terminal equipment is $1,750,000. Note that the addition of air conditioning may require an upgrade to the existing electric service. The cost of the electric service upgrade is broken out separately below but should be included if the cooling option above is incorporated. • In lieu of DX cooling systems recommended above, add conventional water source heat pump system throughout school with heat exchanger and cooling tower -- The estimated budget installed cost for the addition of the heat exchanger and cooling tower as well as demolition and replacement of all piping to be compatible with this system type is $2,100,000. Note that the addition of air conditioning may require an upgrade to the existing electric service. The cost of the electric service upgrade is broken out separately below but should be included if the cooling option above is incorporated. • In lieu of chilled water or DX cooling systems recommended above, add geothermal cooling and heating system -- Note that the existing boilers could remain but would have limited use. The estimated budget installed cost for the addition of geothermal wells, pumps, and electric heat pump unit ventilators and electric heat pump terminal equipment is $3,000,000. Note that the addition of air conditioning may require an upgrade to the existing electric service. The cost of the electric service upgrade is broken out separately below but should be included if the cooling option above is incorporated. • Upgrade Building Management System (BMS) - Currently, the building is controlled by an antiquated, pneumatic temperature control system The BMS should be upgraded to a new Direct Digital Control (DDC) system similar to the Johnson Metasys system to control the new unit ventilators and other equipment replaced as part of the capital improvement recommendations. This upgrade will result in energy savings via improved temperature control and by the elimination of the air compressors. In addition, it was reported by the Supervisor of Buildings & Grounds that about half of the unit ventilators run for 24 hours per day on school days between September and June. In addition, the H&V units and exhaust fans serving the Cafeteria and Multipurpose Room operate from 6:00 am to 11:00 pm on school days. The outside air dampers should open and fans should operate at 8:00 am and close/deenergize at 2:30 pm on each school day. The new DDC system will incorporate this sequence of operation for this equipment. The estimated installed cost of the new controls system is $375,000, including all control, wiring, web-based controller for direct communication and remote control to monitor and alarm all HVAC equipment and all Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 39/86 programming, engineering, training and start-up. It is estimated that proper shut-off of the unit ventilators, H&V units and fans listed above will save about 50,000 kwh and approximately 3,900 therms annually. • Replace common area heating equipment - such as finned tube radiation and cabinet unit heaters in the toilet rooms, vestibules and corridors. This equipment is in fair condition, but age and wear have reduced the heat transfer capacity. This equipment should be replaced with more modern equipment suited for the intended use. These changes cannot be justified based on energy savings alone. However, replacement is strongly recommended along with upgrades to other portions of the heating system. This is a replacement in kind recommendation which offers negligible energy savings. • Replace window air conditioners – Several of the existing window air conditioners still have some useful life remaining (on the average 0-5 years left) but replacement should be considered with modern, energy efficient systems. The window air conditioners should be replaced with split systems to allow for closing up of the existing window or wall penetrations. These upgrades cannot be justified by energy savings alone but will result in a decrease in energy usage versus the existing equipment. In addition, some of the existing systems utilize R-22 refrigerant, which is not an ozone-friendly refrigerant. Newer systems should be specified with R-410A refrigerant. • Upgrade electric service – The existing electric service is rated for 1,600 amperes at 208V3-phase. Based on recent electric demand data from the local utility, there is spare capacity for additional loads in the existing electric service. If cooling is added per some of the recommended capital improvement measures listed above, an upgrade to the electric service is required. The estimated electric service requirement for the addition of air conditioning is 4,000 amps at 208V-3-phase. The estimated budget cost for this upgrade is $150,000. • The following rooms are not provided with code minimum ventilation air: Elementary Guidance Office (A-Wing), Elementary Janitor’s Closet (A-Wing), Nurse’s Office (A-Wing), OT/Speech/Child Study Team Offices (A-Wing), Middle School Guidance Office and adjacent Room P1(D-Wing), Middle School Copy Room (D-Wing) . As part of the recommended unit ventilator replacements, provide these rooms with a unit ventilator or other air handling system with outside air provisions. • Consider replacement of the 1968 Bally walk-in cooler/freezer with a newer model. Although the compressor and condenser package has been replaced, the wall and roof panels of the box itself are likely not insulated to the levels of current walk-in coolers. This is a replacement in kind recommendation which cannot be recommended based on energy savings alone. • Consider replacement of the reach-in milk cooler in cafeteria with more modern, higher efficiency model. • Install premium motors when replacements are required - Select NEMA Premium motors when replacing motors that have reached the end of their useful operating lives. Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 40/86 Category II Recommendations: Operations and Maintenance • Inspect and replace gasketing around door into the walk-in refrigeration boxes in the Kitchen and outside. Ineffective gasketing allows infiltration of warm air into the walk-in box, which increases the run-time of the compressors. • Water levels in the expansion tanks and the integrity of the tank bladder should be checked to confirm proper operation. • Use Energy Star labeled appliances - such as Energy Star refrigerators that should replace older energy inefficient equipment. • Maintain roofs - SWA recommends regular maintenance to verify water is draining correctly. • Maintain downspouts - Repair / install missing downspouts as needed to prevent water / moisture infiltration and insulation damage. • Provide weather stripping / air sealing - Doors and vestibules should be observed annually for deficient weather-stripping and replaced as needed. The perimeter of all window frames should also be regularly inspected and any missing or deteriorated caulking should be recaulked to provide an unbroken seal around the window frames. Any other accessible gaps or penetrations in the thermal envelope penetrations should also be sealed with caulk or spray foam. • Preventative exterior wall maintenance - SWA recommends as part of the maintenance program to install proper flashing, correct masonry efflorescence and seal wall cracks and penetrations wherever necessary in order to keep insulation dry and effective. • Use smart power electric strips - in conjunction with occupancy sensors to power down computer equipment when left unattended for extended periods of time. • Create an energy educational program - that teaches how to minimize their energy use.

Appliances, such as refrigerators, that are over 10-12 years of age should be replaced with newer efficient models with the Energy Star label. SWA recommends the replacement of the existing refrigerator which is operating at the end of its useful lives with a more modern, ENERGY STAR®, energy efficient appliance. Besides saving energy, the replacement will also keep the kitchen area cooler. In addition, the existing systems utilize R-12 refrigerant, which is not an ozone-friendly refrigerant. Newer systems should be specified with R-134A or R-404A refrigerant. When compared to the average electrical consumption of older equipment, Energy Star equipment results in large savings. Look for the Energy Star label when replacing appliances and equipment, including: window air conditioners, refrigerators, printers, computers, copy machines, etc. More information can be found in the “Products” section of the Energy Star website at: http://www.energystar.gov.

Energy vending miser devices are now available for conserving energy with these machines. There is not a need to purchase new machines to reduce operating costs and greenhouse gas emissions. When equipped with the vending miser devices, refrigerated beverage vending machines or coolers use less energy and are comparable in daily energy performance to new ENERGY STAR qualified machines. Vending miser devices incorporate innovative energy-saving technology into small plug-andplay devices that installs in minutes, either on the wall or on the vending machine. Vending miser devices use a Passive Infrared Sensor (PIR) to: Power down the machine when the surrounding area is vacant; Monitor the room's temperature; Automatically repower the cooling system at one- to three-hour intervals, independent of sales; Ensure the product stays cold. Snacks vending miser devices can be used on Snacks vending machines to achieve maximum energy savings that result in reduced operating costs and decreased greenhouse gas emissions with existing machines. Snacks vending miser devices also use a Passive Infrared Sensor (PIR) to determine if there is anyone within 25 feet of the machine. It waits for 15 minutes of vacancy, then powers down the machine. If a customer approaches the machine while powered down, the snacks vending miser will sense the presence and immediately power up.

The existing lighting consists of mostly older inefficient T12 fluorescent fixtures with magnetic ballasts. SWA recommends upgrades to high performance T8 fluorescent bulbs with efficient electronic ballasts. All incandescent bulbs should be replaced with compact fluorescents, using a quarter of the energy. SWA has performed an evaluation of installing occupancy sensors in classrooms, offices and closets where the payback is justified. The labor in all these installations was evaluated using prevailing electrical contractor wages.

Due to this method of providing domestic hot water, the boilers must be fired even during mild weather when there would normally be no space heating load. SWA recommends providing separate tank-type domestic water heaters to handle the domestic water heating load and make required piping modifications to reconnect to the existing domestic water piping system. This will provide energy savings by allowing the school to not fire the boilers during mild weather. Frankford Township School may wish to install two (2) ASME-rated heaters, one in each boiler room, that meet the current requirements of ASHRAE/IESNA Standard 90.1 (similar to AO Smith model COF-199) and remove or disconnect the boiler immersion heaters. Aside from the higher efficiency of the heaters, there should be a savings due to reduced standby losses compared to the current insulated storage tanks. The associated recirculating pump in the A/B Boiler Room appears to be operating adequately and replacement of the pump motor would yield negligible savings since it is fractional horsepower.

SWA recommends replacement of this equipment to see an increase in operating efficiency. This upgrade cannot be justified by energy savings alone. The current equipment has a cooling Energy Efficiency Ratio (EER) of approximately 9.0. The new equipment should have a minimum 11.5 EER rating, preferably closer to 12.5 or 13.0. The higher EER will involve increased cost for the equipment over units with lower EER, but 11.5 EER is the minimum required for this equipment capacity to qualify for a NJ Clean Energy Program rebate. The equipment shall be Energy Star certified and ASHRAE 90.1 compliant. The equipment shall utilize R-410A refrigerant. The compressors shall be fully hermetic, scroll type with on demand crankcase heaters for cooling duty and induced draft fuel oil #2 combustion for heating duty. Evaporator fan wheel shall be steel with a corrosion-resistant finish, shall be doubleinlet type with forward-curved blades and shall be dynamically balanced. Fan motors shall be continuous operation, open-drip proof with sealed, permanently lubricated ball bearings. Evaporator and condenser coils shall have aluminum lanced plate fins mechanically bonded to seamless internally grooved copper tubes with all joints brazed. Heat exchanger shall be aluminized 20gage steel coated with 1.2 mil aluminum-silicone alloy or similar for corrosion resistance.

Appliances, such as refrigerators, that are over 10-12 years of age should be replaced with newer efficient models with the Energy Star label. SWA recommends the replacement of the existing refrigerator which is operating at the end of their useful life with a more modern, ENERGY STAR®, energy efficient system. Besides saving energy, the replacement will also keep the kitchen and other areas cooler. In addition, the existing systems utilize R-12 refrigerant, which is not an ozone-friendly refrigerant. Newer systems should be specified with R-134A or R-404A refrigerant. When compared to the average electrical consumption of older equipment, Energy Star equipment results in large savings. Look for the Energy Star label when replacing appliances and equipment, including: window air conditioners, refrigerators, printers, computers, copy machines, etc. More information can be found in the “Products” section of the Energy Star website at: http://www.energystar.gov.

Conditioning outside air can be a significant portion of the heating load seen by the air handling unit. Demand control ventilation involves providing carbon dioxide (CO 2 ) sensors in the occupied space to estimate occupancy. When the space is underutilized or unoccupied during occupied hours, the CO 2 sensors can partially or totally shut down the outside air intake damper to the air handling unit. This control method can greatly reduce the heating or cooling load seen by the air handling unit and therefore save energy. The Frankford Township School will realize energy savings by installing the required control devices and incorporating this control method into the new BMS system programming.

Renewable energy systems such as photovoltaic panels, can be mounted on the building roofs, and can offset a portion of the purchased electricity for the building. Power stations generally have two separate electrical charges: usage and demand. Usage is the amount of electricity in kilowatthours that a building uses from month to month. Demand is the amount of electrical power that a building uses at any given instance in a month period. During the summer periods, when electric demand at a power station is high due to the amount of air conditioners, lights, equipment, etc… being used within the region, demand charges go up to offset the utility’s cost to provide enough electricity at that given time. Photovoltaic systems not only offset the amount of electricity use by a building, but also reduce the building’s electrical demand, resulting in a higher cost savings as well. It is recommended at this time that the Frankford Township School further review installing a 151.2 kW PV system to offset electrical demand and reduce the annual net electric consumption for the building, and review guaranteed incentives from NJ rebates to justify the investment. Frankford Township School is also not eligible for a 30% federal tax credit. Instead, the Frankford Township School may consider applying for a grant and/or engage a PV generator/leaser who would install the PV system and then sell the power at a reduced rate. JCP&L provides the ability to buy SREC’s at $600/MWh or best market offer. There are many possible locations for a 151.2 kW PV installation on the building roofs. A commercial crystalline 230 watt panel has 17.5 square feet of surface area (13.1 watts per square foot). Considering the shading on the roof of this facility, a 151.2 kW system needs approximately 720.0 panels which would take up 12,600 square feet.

As mentioned above, NJ Clean Energy incentives are available for systems no larger than 50 kW. A 49.7 kW PV system would qualify for such incentives JCP&L provides the ability to buy SREC’s at $600/MWh or best market offer. There are many possible locations for a 49.7 kW PV installation on the building roofs. A commercial crystalline 230 watt panel has 17.5 square feet of surface area (13.1 watts per square foot). Considering the shading on the roof of this facility, a 49.7 kW system needs approximately 236.0 panels which would take up 4,130 square feet.

RENEWABLE AND DISTRIBUTED ENERGY MEASURES 5.1. Existing systems There are not currently any existing renewable energy systems. 5.2. Wind Description: A Wind system is not applicable for this building because the area does not have winds of sufficient velocity to justify installing a wind turbine system. 5.3. Solar Photovoltaic Please see the above recommended ECM#12 or 12a. 5.4. Solar Thermal Collectors Description: Solar thermal collectors are not cost effective for this building and would not be recommended due to the insufficient and not constant use of domestic hot water throughout the building to justify the expenditure. 5.5. Combined Heat and Power Description: CHP is not applicable for this building because of insufficient thermal baseload. 5.6. Geothermal Description: Currently, the building is heated but not cooled. Should the school district investigate the addition of air conditioning to the school’s HVAC system, an estimated energy savings analysis versus other systems can be studied. Several system types have been studied and the system summaries and estimated costs have been presented in the Capital Improvements section above.

Tariff analysis Currently, fuel oil #2 is supplied to the Frankford Township School building by Flinch Fuel oil, sold to the Township School at a the prevailing market rate. Typically, the fuel oil #2 prices increase during the heating months when fuel oil #2 is used by the hot water boiler units. The high fuel oil #2 price per therm in the summer may be due to high energy costs that occurred in 2008. The price for the months of June to September is flat because the school did not purchase any fuel during this period, only using the fuel purchased in April/May. $3.500 12,000 $3.000 10,000 $2.500 8,000 $2.000 6,000 $1.500 4,000 $1.000 2,000 $0.500 $0.000 Mar '09 Feb '09 Nov '08 Oct '08 Sept.

Fuel Oil Rate ($/therm) Date (Month-Year) Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 74/86 The Frankford Township School building is direct-metered (via one main meter) and currently purchases electricity from the local utility at a general service rate. The general service rate for electric charges are market-rate based on use and the Frankford Township School building billing does show a breakdown of demand costs. Demand prices are reflected in the utility bills and can be verified by observing the price fluctuations throughout the year. Typically, the electricity prices increase during the cooling months when electricity is used by air conditioning equipment. 6.3. Energy Procurement strategies The Frankford Township School building receives fuel oil #2 from Flinch Fuel oil supplies the fuel oil #2 and transports it. There is not an ESCO engaged in the process. An Energy Services Company (ESCO) is a consultancy group that engages in a performance based contract with a client firm to implement measures which reduce energy consumption and costs in a technically and financially viable manner. Electricity is also purchased via one incoming meter directly for the Frankford Township School building from Frankford Township electric utility consortium without an ESCO. SWA analyzed the utility rate for fuel oil #2 and electricity supply over an extended period. Electric bill analysis shows fluctuations up to 20% over the most recent 12 month period. Some of these fluctuations may have been caused by adjustments between estimated and actual meter readings, others may be due to unusual high and escalating energy costs in 2008. The average estimated NJ commercial utility rates for electric and fuel oil #2 are $0.150/kWh and $2.19/gallon respectively. The Frankford Township School building annual electric cost is $6,703 higher for electric when compared to the average estimated NJ commercial electric rates. The fuel oil was purchased at competitive rates. SWA recommends that the Frankford Township School Board of Education further explore opportunities of purchasing electricity from an ESCO in order to reduce rate fluctuation and ultimately reduce the annual cost of energy for the Frankford Township School building. Appendix B contains a complete list of third party energy suppliers for the Frankford Township service area. The Frankford Township School Board of Education may want to consider partnering with other school districts, municipalities, townships and communities to aggregate a substantial electric and fuel oil #2 use for better leveraging in negotiations with their local utility and ESCOs. This sort of activity is happening in many parts of the country and in New Jersey. Also, the Frankford Township School building would not be eligible for enrollment in a Demand Response Program, because there isn’t the capability at this time (without a large capital investment) to shed a minimum of 150 kW electric demand when requested by the utility during peak demand periods, which is the typical threshold for considering this option. The following charts show the Frankford Township School building monthly spending per unit of energy in 2008.

and Method of Calculations Glossary of ECM Terms . Net ECM Cost: The net ECM cost is the cost experienced by the customer, which is typically the total cost (materials + labor) of installing the measure minus any available incentives. Both the total cost and the incentive amounts are expressed in the summary for each ECM. Annual Energy Cost Savings (AECS): This value is determined by the audit firm based on the calculated energy savings (kWh or Therm) of each ECM and the calculated energy costs of the building. Lifetime Energy Cost Savings (LECS): This measure estimates the energy cost savings over the lifetime of the ECM. It can be a simple estimation based on fixed energy costs. If desired, this value can factor in an annual increase in energy costs as long as the source is provided. Simple Payback: This is a simple measure that displays how long the ECM will take to breakeven based on the annual energy and maintenance savings of the measure. ECM Lifetime: This is included with each ECM so that the owner can see how long the ECM will be in place and whether or not it will exceed the simple payback period. Additional guidance for calculating ECM lifetimes can be found below. This value can come from manufacturer’s rated lifetime or warranty, the ASHRAE rated lifetime, or any other valid source. Operating Cost Savings (OCS): This calculation is an annual operating savings for the ECM. It is the difference in the operating, maintenance, and / or equipment replacement costs of the existing case versus the ECM. In the case where an ECM lifetime will be longer than the existing measure (such as LED lighting versus fluorescent) the operating savings will factor in the cost of replacing the units to match the lifetime of the ECM. In this case or in one where one-time repairs are made, the total replacement / repair sum is averaged over the lifetime of the ECM. Return on Investment (ROI): The ROI is expresses the percentage return of the investment based on the lifetime cost savings of the ECM. This value can be included as an annual or lifetime value, or both. Net Present Value (NPV): The NPV calculates the present value of an investment’s future cash flows based on the time value of money, which is accounted for by a discount rate (assumes bond rate of 3.2%). Internal Rate of Return (IRR): The IRR expresses an annual rate that results in a break-even point for the investment. If the owner is currently experiencing a lower return on their capital than the IRR, the project is financially advantageous. This measure also allows the owner to compare ECMs against each other to determine the most appealing choices. Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 83/86 Calculation References ECM = Energy Conservation Measure AOCS = Annual Operating Cost Savings AECS = Annual Energy Cost Savings LOCS = Lifetime Operating Cost Savings LECS = Lifetime Energy Cost Savings LCS = Lifetime Cost Savings NPV = Net Present Value IRR = Internal Rate of Return DR = Discount Rate Net ECM Cost = Total ECM Cost – Incentive LECS = AECS X ECM Lifetime AOCS = LOCS / ECM Lifetime LCS = LOCS+LECS Note: The lifetime operating cost savings are all avoided operating, maintenance, and / or component replacement costs over the lifetime of the ECM. This can be the sum of any annual operating savings, recurring or bulk (i.e. one-time repairs) maintenance savings, or the savings that comes from avoiding equipment replacement needed for the existing measure to meet the lifetime of the ECM (e.g. lighting change outs). Simple Payback = Net ECM Cost / (AECS + AOCS) Lifetime ROI = (LECS + LOCS – Net ECM Cost) / Net ECM Cost Annual ROI = (Lifetime ROI / Lifetime) = (AECS + OCS) / Net ECM Cost – 1 / Lifetime It is easiest to calculate the NPV and IRR using a spreadsheet program like Excel. Excel NPV and IRR Calculation In Excel, function =IRR(values) and =NPV(rate, values) are used to quickly calculate the IRR and NPV of a series of annual cash flows. The investment cost will typically be a negative cash flow at year 0 (total cost - incentive) with years 1 through the lifetime receiving a positive cash flow from the annual energy cost savings and annual maintenance savings. The calculations in the example below are for an ECM that saves $850 annually in energy and maintenance costs (over a 10 year lifetime) and takes $5,000 to purchase and install after incentives: Frankford Township School SWA, Inc. - Local Government Energy Audit Report Page 84/86 ECM and Equipment Lifetimes Determining a lifetime for equipment and ECM’s can sometimes be difficult. The following table contains a list of lifetimes that the NJCEP uses in its commercial and industrial programs. Other valid sources are also used to determine lifetimes, such as the DOE, ASHRAE, or the manufacturer’s warranty. Lighting is typically the most difficult lifetime to calculate because the fixture, ballast, and bulb can all have different lifetimes. Essentially the ECM analysis will have different operating cost savings (avoided equipment replacement) depending on which lifetime is used. When the bulb lifetime is used (rated burn hours / annual burn hours), the operating cost savings is just reflecting the theoretical cost of replacing the existing case bulb and ballast over the life of the recommended bulb. Dividing by the bulb lifetime will give an annual operating cost savings. When a fixture lifetime is used (e.g. 15 years) the operating cost savings reflects the avoided bulb and ballast replacement cost of the existing case over 15 years minus the projected bulb and ballast replacement cost of the proposed case over 15 years. This will give the difference of the equipment replacement costs between the proposed and existing cases and when divided by 15 years will give the annual operating cost savings. .

EUI, expressed in kBtu/sf, is normalized for floor area, the most dominant influence on energy use in most buildings. Its use usually provides a good approximation of how your building's energy performance compares to others. Site EUI indicates the rate at which energy is used at your building (the point of use). Source EUI indicates the rate at which energy is used at the generation sources serving your building (the point of source) and indicates the societal energy penalty due to your building The lower the EUI, the higher the rating, indicating that the building is more efficient than other buildings. The greater the EUI, the lower the rating, indicating that there is an opportunity for higher potential benefits from operational improvements. To compare the buildings shown below to each other, and to determine the ranking of the buildings from having the most to the least opportunity for demand-side improvements from a financial perspective, please see the Site EUI ranking below. The Source EUI below has been applied to a Department of Energy statistical model from the Oak Ridge National Laboratory web site, http://eber.ed.ornl.gov/benchmark. The Department of Energy has estimated energy use and cost reductions for building source EUI ratings (percentiles) in the table below. Please see the DOE Regional Source EUI Comparison graph below to rate your building in relation to the regional distribution of similar type buildings. (Note: The Source EUI includes the inefficiencies of electrical generation and transmission. A reduction in 'electrical' source EUI includes a benefit in terms of reduction of air pollution emissions and green house gases, and is thus an indicator of societal benefit.)

SECTION B: ENERGY CONSERVATION MEASURES 2 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan INTRODUCTION The information used to develop this Section was obtained through building surveys to collect equipment information, interviews with facility personnel, and an understanding of the components to the systems at the sites. The information obtained includes nameplate data, equipment age, condition, the system’s design and actual load, operational practices and schedules, and operations and maintenance history. Honeywell has done a review of the ECMs which would provide energy and cost savings to the Frankford Township School District. This report aims to be an assessment of the feasibility and cost effectiveness of such measures, and an indication of the potential for their implementation. The measures are listed below, as well as a general description of the energy auditing process. More detailed descriptions are also included.

These selected site-specific measures have been developed using the following process: Review Site Audits Engineering Team Site Visits Develop Measures Review Measures with Team Reject and Accept Measures Based On: 1. Alignment with Critical Success Factors (CSF) 2. Value to the District 3. Economic Financial Payback 4. Equipment Service Life 5. Effect on Current Space Conditions In developing the proposed measures, the following considerations were critical: Reduction of space heating and cooling loads by performing a system review, with complete consideration of current indoor environmental quality standards. Review and redesign lighting systems noting reductions in the internal heat gain in the affected spaces. Load reduction measures always precede optimization measures. The following project goals, as called for in RFP, were also critical in the development of our Energy Savings Plan response: Automated heating and cooling controls with web based management High efficiency boilers and water heaters Lighting upgrades to high efficiency fluorescents Window replacements Air handler replacements and controls Alternative energy systems Energy usage monitoring Energy Education, LEED, Energy Star Process Bin weather data was used from a 15 year average reported from Newark Liberty International Airport, Newark, NJ. Assumptions for ventilation rates were predicted by using the building’s population multiplied by 15 cfm/person during occupied hours. Reasonable infiltration rates were assumed based expected values for typical school buildings. A unoccupied hours. Envelope heat loss calculations value) based on the construction of the buildings. energy audit report. SECTION B: ENERGY CONSERVATION MEASURES 5 on the building’s fenestration conditions and reduced infiltration rate was assumed for the assumed a reasonable heat transmission rate (U Wall area and glass area were estimated by the Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Current efficiencies were derived from assumed boiler efficiencies, and assumed system losses due to thermal losses, distribution losses and loose operational control. The current assumed boiler system efficiencies were then applied to the calculated load and calibrated to last year’s actual fuel consumption. Demand Sensitive Operation Review existing and proposed thermal loads. For example, the review process will facilitate the application of: 1. Optimized flow rates (water and air) 2. Optimized operation of equipment, matching current occupancy use profiles and considering both outside and indoor space temperatures. Benefits of Mechanical Improvements Listed below are some of the benefits that the District would reap from the mechanical portion of the measures: 1. Avoid costly repairs and replace equipment that would have to be replaced in the next five years. 2. Improved compliance with ASHRAE Ventilation Standards. 3. Ability to trend ventilation rates; thus, ensuring compliance through documentation. 4. Operating a more weather sensitive facility. 5. Allowing for a greater capability of central monitoring and trouble shooting via remote. 6. Greater operating flexibility. Indoor Air Quality Implementation of new energy-related standards and practices has contributed to a degradation of indoor air quality. In fact, the quality of indoor air has been found to exceed the Environmental Protection Agency (EPA) standards for outdoor air in many homes, businesses, and factories. The American Council of Governmental Industrial Hygienists (ACGIH) in their booklet “Threshold Limit Values,” has published air quality standards for the industrial environment. No such standards currently exist for the residential, commercial, and institutional environments, although the ACGIH standards are typically and perhaps inappropriately used. The EPA has been working to develop residential and commercial standards for quite some time. Recent studies indicate that for even the healthiest students, indoor air pollution can reduce the ability to learn. As an example, if you were to place a number of students in a room where it’s hot, there’s little or no air circulation and other children are coughing and sneezing, their ability to concentrate drops significantly. Honeywell has addressed this issue by focusing on the proper operation of the unit ventilators and air handler equipment which will assure IAQ standards are met. SECTION B: ENERGY CONSERVATION MEASURES 6 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan ECM 1A Vending Misers The Frankford Township School facility has plug loads, such as vending machines. As such, Honeywell has investigated the use of plug controllers for these areas. Existing Conditions Vending machines are located throughout the facility, offering soft drinks to the occupants. A typical cold drink machine consumes over 3,000 kWh annually. Item 1 Building Frankford Township School Type Cold Drinks Machines Quantity 3 Proposed Solution During the site visit, Honeywell noted vending machines providing the opportunity for energy savings by shutting off non-critical loads during the non-occupied periods. To control the vending machines, Honeywell proposes to install a vending machine occupancy controller (VMOC) to manage the power consumption. Utilizing a Passive Infrared (PIR) Sensor, the VMOC completely powers down a vending machine when the area surrounding it is unoccupied. Once powered down, the VMOC will monitor the room’s temperature and use this information to automatically re-power the vending machine at one to three hour intervals, independent of occupancy, to ensure that the vended product stays cold. The VMOC also monitors electrical current used by the vending machine. This ensures that the unit will never power down a vending machine while the compressor is running, so a high head pressure start never occurs. In addition, the current sensor ensures that every time the vending machine is powered up, the cooling cycle is run to completion before again powering down the vending machine. The Coca Cola Company and Pepsi Corporation approve the proposed controller for use on their machines. SECTION B: ENERGY CONSERVATION MEASURES 7 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Using state-of-the-art electronics, VendingMiser is able to automatically determine whether or not the compressor of the vending machine is operating. Therefore, VendingMiser will never short cycle the compressor. The VendingMiser uses a custom occupancy sensor to determine if there is anyone within 40 feet of the machine. VendingMiser waits for 15 minutes of vacancy and then completely powers off the vending machine. If the compressor is running, power down is delayed until the cycle-in-process is completed. Once powered off, VendingMiser will monitor the room’s temperature, and based on this measurement will automatically re-power the vending machine to run a complete cooling cycle, and then powers it down again. If a customer approaches the vending machine while powered down, VendingMiser will sense the person’s presence and power up immediately. Interface with Existing Equipment All of the plug load control devices are easily installed. The vending machine controllers are installed separately from the machine, and implementation will occur during working hours. A period of three (3) weeks will be required to make sure of proper calibration of the sensors. With respect to the vending machines in your facilities, Honeywell has estimated the number and types of vending machines. During the implementation phase, Honeywell will check with the vendor about the type and specification of the vending machines as it relates to any internal time clocks which may exist inside the machine. Should this be the case, the savings and cost will be adjusted accordingly. SECTION B: ENERGY CONSERVATION MEASURES 8 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan ECM 1B Lighting Retrofit and Motion Sensors Existing Conditions In general, lighting is the largest component of school building’s electric usage (approximately 30%). By upgrading the existing lighting to the latest 28-watt electronic T8 technology, substantial cost savings will be achieved. The data and analysis outlined in this report is a snapshot of building conditions as of March 10, 2010. Currently, there is mainly F32/T8 fixtures in this project. We recommend the installation of the latest technology electronic T8 ballasts and F32/T8 28-watt lamps in the majority of the fixtures, and installing reflectors and de-lamping fixtures whenever possible. Low power ballasts will be used and fixtures will be tandem-wired whenever possible, to save more energy without compromising light levels. The implementation of this efficient lighting design will not only provide cost savings, but also reduce the cooling load of a building. Using the latest technology ballasts and lamps in combination of de-lamping (in some locations) will generate less heat from the lighting fixtures reducing cooling loads and electrical loads which can translate into smaller HVAC equipment being specified, thus decreasing future capital cost outlays. Proposed Solution The existing 2-lamp and 4-lamp F32T12 recessed and ceiling mounted and suspended fixtures present mainly in the classrooms, gymnasium, kitchen, hallways and offices will be retrofitted with electronic ballast, 28-watt T8 lamps and reflector. Existing incandescent fixtures will be retrofitted with compact fluorescent lamps. Lighting Controls Currently there are no occupancy sensor controls in this school. New sensors will contain the latest dual-sensor technology (passive infrared and ultrasonic activated). The ultrasonic aspect of the sensor will detect "minor" motion while the passive infrared aspect will detect long-range "major" motion. Based on observation, there were lights on in some unoccupied rooms. For brightly day lit breezeways/hallways, installation of daylight harvesting controls will save substantial energy by turning off lights when natural light levels hit predetermined foot-candle levels. When artificial light is necessary, the lights will automatically turn on. Changes in Infrastructure New lamps and ballasts will be installed as part of this ECM. SECTION B: ENERGY CONSERVATION MEASURES 9 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Customer Support and Coordination with Utilities Coordination efforts will be needed to reduce or limit impact to building occupants. Environmental Issues Resource Use Energy savings will result from reduced electric energy usage. A slight increase in heating energy is resultant from the reduced heat output of more efficient lamps. Waste Production All lamps and ballasts that are removed will be properly disposed. Environmental Regulations No environmental impact is expected. SECTION B: ENERGY CONSERVATION MEASURES 10 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan ECM 1C Replace Refrigerators Existing Conditions There are three (3) older refrigerators in the lounge areas which are not Energy Star rated (using as much as 1,700 kWh/yr each). The replacement of the existing refrigerators which are operating at the end of their useful lives with more modern, ENERGY STAR®, energy efficient appliances is recommended. Proposed Solution Appliances, such as refrigerators, that are over 10-12 years of age should be replaced with newer efficient models with the Energy Star label. Besides saving energy, the replacement will also keep the lounge area cooler. In addition, the existing systems utilize R-12 refrigerant, which is not an ozonefriendly refrigerant. Newer systems should be specified with R-134A or R-404A refrigerant. When compared to the average electrical consumption of older equipment, Energy Star equipment results in large savings. Look for the Energy Star label when replacing appliances and equipment, including: window air conditioners, refrigerators, printers, computers, copy machines, etc. Equipment Information Equipment Identification Product cut sheets and specifications generally used are available upon request. As part of the measure design and approval process, specific product selection will be provided for your review and approval. Changes in Infrastructure New Energy Star labeled refrigerators will be installed in the lounge areas. No expansion of the facilities will be necessary.

SECTION B: ENERGY CONSERVATION MEASURES 12 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan ECM 2A Boiler Combustion Controls Existing Conditions The information used in developing this Energy Conservation Measure (ECM) was obtained through interviews with building operators, conditions observed during visits to the buildings, manufacturer’s technical literature for existing and new equipment and data obtained through various technical publications. Honeywell has evaluated the school building’s heating and domestic hot water equipment and distribution systems to identify areas for boiler plant optimization. The three (3) HB Smith hot water boilers at Frankford Township School were manufactured in 1986 and 1992. The fuel used in these boilers is No. 2 fuel oil. The boilers are not equipped with mechanical linkage to control the air/fuel ratio through the firing range. The A/B wing boiler room has two (2) boilers; one serves the A wing and the other serves the B wing. The A wing boiler can be manually valved to supplement the boiler serving the C and D wings. The A boiler water temperature is currently controlled manually via aquastat on the boiler and there did not appear to be any pressure control. The B boiler has a lead/lag pump pair, a 3-way mixing valve for water temperature control and a 2-way bypass valve for pressure control. All controls are pneumatic. The C/D wing boiler room has a single hot water boiler and two (2) hot water heating zones, one for the C wing and one for the D wing. Each zone has a lead/lag pump pair, a 3-way mixing valve for water temperature control and a 2-way bypass valve for pressure control. Proposed Solution Leaving the pumps on (and shutting the boiler off) effectively cools the water down to ambient temperatures. When a typical water boiler fires on temperature control, it would go directly to high fire, subjecting the boiler to “thermal shock”. Repeating this thermal cycling on a daily basis could result in boiler damage. How long the boiler lasts is solely a function of how well it was built, but be aware that shocking the boiler in this manner is not part of modern boiler design or operating strategy. Another negative side effect of leaving pumps on while shutting boilers off is that while the loop is brought up to temperature, the cold water reduces the stack temperature below what it needs to prevent condensation. So, every cycle is also dropping water through the fire-side of the boiler, effectively accelerating rust and eating the boiler from the inside out. When condensation mixes with combustion gases, it becomes very acidic. SECTION B: ENERGY CONSERVATION MEASURES 13 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Honeywell recommends reducing the boiler operating temperature closer to the minimum allowed by the manufacturer. Most current hydronic systems have independent loop temperature control, but Boiler A does not. The independent loop temperature control is most often modulated using a 3-way valve typically mounted above the boiler. This valve allows the water being pumped through the building to be a different, lower temperature than what is going through the boiler. The loop temperature control is then modulated according to outside air temperature. This is done for two major reasons: it saves energy by reducing the loop temperature to the building as the outside air temperature rises during the day and it allows the boiler to operate as a constant temperature. This creates no thermal cycling and no stack condensation. It is recommended that boilers be left on all winter and building temperatures be controlled via the circulating pumps. By switching off the circulation pumps, the heat to the building is stopped. This can be done nightly during the spring and fall. The water sits in the hot water lines throughout the building and the temperature does not drop so much. The boiler stays at temperature. It stops cycling (and therefore uses little or no fuel oil) because no water is moving and it is quite easy to keep the water in the boiler at 160°F. When the pumps kick back on, the hot water in the boiler and the warm water in the lines limit thermal cycling. During periods of mild weather, the 3-way valve is calling for reduced loop temperature, further reducing the flow of water through the boiler and allowing it to maintain its own operating temperature. This saves both energy and the boiler. While there are a few exceptions to this, it holds true for the most part. When the outside air is freezing, the pumps must run to prevent the coils from freezing. So, in the dead of winter, there is little you can do in the boiler room. You are relegated to ensuring the 55°F setback is taking place in the building. In addition, new single phase 120 volt combustion air fans shall be installed in each boiler room and interlocked to the boiler start/stop. This will ensure adequate combustion air. Energy Savings Methodology and Results The approach is based upon increasing the efficiency with improved combustion and hot water reset energy savings. The baseline adjustment calculations are included with the energy calculations. Changes in Infrastructure None Customer Support and Coordination with Utilities Minor support will be required for the interruption of utilities for brief tie-in periods. Environmental Issues Resource Use Energy savings will result from reduced energy. Waste Production Environmental Regulations Any removed parts will be disposed of properly. No environmental impact is expected. SECTION B: ENERGY CONSERVATION MEASURES 14 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan ECM 2B Boiler Replacements Boiler Replacement: A common misperception of boiler performance is the term boiler efficiency, which is often substituted for the user’s intended reference to combustion efficiency; traditionally measured at full load. While full load combustion efficiency is an important component to the performance of a boiler, part load operation and thermal efficiency are often overlooked, but significant contributors to overall boiler operation. Boiler efficiency gains can be measured in three ways: combustion efficiency, thermal efficiency, and seasonal efficiency. Combustion efficiency gains can be realized through optimization of fuel, air mixtures and close control of the combustion process under all load conditions. Overall efficiency, while affected by the combustion process, also considers losses due to radiation, pre- and post- purge cycles on burner startup and shutdown, blow down losses, etc. Reduction of any of these losses will improve the boilers’ overall efficiency. Seasonal efficiency is the actual efficiency that is achieved under various load conditions during the course of the heating season. Existing Conditions Frankford Twp. School The existing boilers were manufactured in 1986 and 1992. At this age, the overall boiler efficiency is reducing year by year with additional cost of maintenance. Sooner or later the boilers will have to be replaced with new boilers. SECTION B: ENERGY CONSERVATION MEASURES 15 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Existing Conditions Branchville School The existing boilers were manufactured in 1975, however only one of the boilers are currently operating.

The burners are currently oil fired to produce warm air to heat the building. Boiler Burner efficiency is based on AFUE. The annual fuel utilization efficiency (AFUE; pronounced 'A'-'Few') is a thermal efficiency measure of combustion equipment like furnaces, boilers, and water heaters. The AFUE differs from the true 'thermal efficiency' in that it is not a steady-state, peak measure of conversion efficiency, but instead attempts to represent the actual, season-long, average efficiency of that piece of equipment, including the operating transients.

SECTION B: ENERGY CONSERVATION MEASURES 24 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan ECM 3A BMS System Upgrades General Existing Conditions Frankford School The school consists of the original structure built around 1950 that was renovated in 1984 (the ‘A’ wing) and three additional wings built in 1958, 1968, and 1974 (referred to as the B, C, and D wings respectively). The controls are primarily hot water unit ventilators (approximately 46) with pneumatic controls. There are (4) pneumatically controlled HV units (2 in the large gym/auditorium, 1 in the small gym, and a small unit in the kitchen). There is a small packaged HVAC unit that serves the office area that is controlled by a space mounted electronic thermostat. Proposed Building Management System Upgrades Frankford School Based on conversations with the building manager and on visual inspection, the pneumatic control system is in poor shape. The control tubing is old and cracking and has numerous leaks. The compressors are leaking oil and the dryers did not have automatic drains, indicating that there may be a lot of oil and water in the control tubing that can cause poor operation or failure of control devices. Due to these conditions, it is Honeywell’s recommendation that the pneumatic control system be abandoned and a new DDC control system be installed. This will result in improved comfort and less energy waste due to improved control.

SECTION B: ENERGY CONSERVATION MEASURES 27 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan General Existing Conditions Branchville School The original building was built in 1872, with renovations during the 1920’s. The controls are primarily hot water unit ventilators with electric controls for the classrooms. Most of the existing systems predominately utilize electric thermostat control. There is no front end or central control of the thermostats which in most cases can be accessed by any facility staff. Any changes that need to be made can only be made at the individual thermostat. Proposed Building Management System Upgrades Branchville School Honeywell has a solution, which in the long run and throughout the course of restoring the control system and future upgrades, will be most cost effective.

Energy Savings Methodology and Results The energy savings for this ECM is realized at the buildings’ HVAC equipment due to better control of the HVAC systems, night set-back and set-up temperatures, start/stop etc. Environmental Issues Resource Use Energy savings will result from reduced electric energy usage and better occupant comfort. Waste Production This measure will produce no waste byproducts. Environmental Regulations No environmental impact is expected. SECTION B: ENERGY CONSERVATION MEASURES 30 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan ECM 3B Demand Control Ventilation Existing System: The air handling units (AHU) serving large one zone spaces such as auditoriums, gymnasiums and cafeterias are often designed for peak occupancy conditions to supply 100% outside air to the space with all return air from space being exhausted. Most of the time these spaces are not fully occupied, which increase energy demand for heating of excessive amount of outside air. Proposed Solution Under this proposal, Honeywell will install CO2 sensors at large one zone rooms that are served by AHUs. The CO2 sensor will provide the control signal for the air handlers to optimize the quantity of fresh air that is required. This control strategy will reduce the space energy use. Based on this fact, there is a reduced requirement for outside air to this space. The installation of a CO2 sensor will read the levels of CO2 in the space and ensure that only the required air is supplied to meet minimum outdoor air requirements. The amount of outside air is introduced and heated. These control systems will be utilized on the large gymnasium/cafeteria/multipurpose air-handling units. Proposed System: Under this proposal, Honeywell will install CO2 sensors to control the amount of outside air entering this space based on demand. For a large area such as this which has erratic occupancy patterns, you are introducing large quantities of outside air into the space when it is not needed. For a majority of time, this area is used on occasion or empty. Based on this fact, there is a reduced requirement for outside air to this space. The installation of a CO2 sensor will read the levels of CO2 in the space and ensure that only the required air is supplied to meet minimum outdoor air requirements. The amount of outside air is introduced and heated.

The savings are generally calculated as: Existing Heating BTU & Cost per BTU Cost of Existing Heating Reduction in Heating BTU Cost of Proposed Heating Energy Savings $ = Metered Data from Existing meter readings = Average Site Data $/Therm = Reduction in Outside air cfm x 1.08 x Delta T x Fan Hours = BTU x Cost per BTU = Existing Heating Costs – Proposed Heating Costs The baseline adjustment calculations are included with the energy calculations.

SECTION B: ENERGY CONSERVATION MEASURES 32 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan ECM 4A Building Envelope Improvements Existing Conditions for Frankford and Branchville Schools: Typically, many schools have problems associated with the design and construction of the buildings. Being older, the school building avoids some of the common failure associated with more modern construction. Plus, long-term stewardship of the structure has helped avoid most of the problems often associated with maintenance issues. But there are several significant building envelope retrofit opportunities, which will provide cost savings and comfort improvements to the building occupants. For the most part, the windows at these schools are in fair condition and functioning. The installation of the windows appeared average, but there is air leakage. Windows that have air conditioning units in them are prone to allow leakage. The units are left in all winter. The District may want to consider removing these units during the cold months. The areas of concern deal with the openings in the “skin” that are mostly “built-in” during the original construction, created during a “retrofit period” and/or have deteriorated. Air leakage is defined as the “uncontrolled migration of conditioned air through the building envelope.” Caused by pressure differences due to wind, chimney (or stack) effect, and mechanical systems, it has been shown to represent the single largest source of heat loss or gain through the building envelopes of nearly all types of buildings. Tests carried out by the National Research Council of Canada on high rise commercial and residential buildings, schools, supermarkets, and houses, have shown levels of 30 % to 50% of heat loss could be attributed to air leakage. Reports detailing this are available for perusal. Beyond representing potential for energy savings, uncontrolled air leakage can affect thermal comfort of occupants, air quality through ingress of contaminants from the outside, and the imbalance of mechanical systems, and the structural integrity of the building envelope - through moisture migration. Control of air leakage involves the sealing of gaps, cracks and holes, using appropriate materials and systems, to create, if possible, a continuous plane of “air-tightness” to completely encompass the building envelope. Part of this process also incorporates the need to “compartmentalize” components of the building in order to equalize pressure differences. The buildings were inspected visually to identify locations and severity of air leakage paths. Air leakage paths are detailed in the scope of work below. Floor plans will be used to mark locations of air sealing measures when completed. SECTION B: ENERGY CONSERVATION MEASURES 33 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Proposed System Honeywell proposes the sealing of these openings through the use of weather-stripping, caulking, and foam sealing. This sealing will occur, as required, at the locations where the roof meets the wall structures and door openings. This will reduce the air leakage of the buildings, and improve the energy efficiency of the structures by tightening their integrity. Weather-stripping will be replaced at the doors where required, and window perimeters will be caulked adequately. Benefits The sealing of the school buildings will allow for more efficient operation of the buildings by reducing heating and cooling losses throughout the year. In addition, the draftiness of the buildings, along with hot and cold spots, will be reduced as a result of this measure. A reduction in air infiltration will also minimize potential concerns for dirt infiltration or indoor air quality. Scope of Work: The Scope of work at Frankford Township School District may include but is not be limited to the following: Weather-strip doors Seal roof/wall intersections Seal penetrations Install window weather strip Seal window perimeters with caulk Seal a/c units Seal passive roof vents Seal and insulate the attic Energy Savings Methodology and Results The energy savings for this ECM are realized at the buildings’ HVAC equipment. The improved building envelopes will limit conditioned air infiltration through openings in the buildings’ air barrier. Less infiltration means less heating required by the heating system. Changes in Infrastructure Building envelopes will be improved with little or no noticeable changes. Customer Support and Coordination with Utilities Minimal coordination efforts will be needed to reduce or limit impact to building occupants. Environmental Issues Resource Use Waste Production Environmental Regulations Energy savings will result from reduced HVAC energy usage and better occupant comfort. Some existing caulking and weather-stripping will be removed and disposed of properly. No environmental impact is expected. SECTION B: ENERGY CONSERVATION MEASURES 34 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan ECM 4B Window Replacements Existing Conditions The existing windows at the Frankford Township School are mainly single pane, aluminum framed windows and appear to be in fair condition. The seals of the windows are ineffective and do not provide an air tight seal from exterior conditions, increasing the loss of expensive conditioned air. The windows are non-thermal break single glazed with uninsulated panels above them and are energy inefficient. Typically, windows contribute to more than 50% of the summertime cooling and more than 25% of the winter heating loads of a building. Window blinds/shades can decrease the solar radiation entering through windows during the summer and limit heat loss during the winter. The resulting energy savings can be substantial. Proposed Solution Honeywell proposes the installation of double-glazed, thermally broken, low Emissivity, aluminum framed windows of approximately 2,400 square feet of the building. This will increase the insulation value of the windows, thus improving the U-Value of the windows. Recommended Applications: Cooling-load-dominated buildings (by restricting solar heat gain) Buildings where occupants have complaints of excessive heat in the summer Building with clear single-pane glass Energy Savings Methodology Energy savings will result from significantly reducing the heating requirement of the perimeter and the front entrance way. In general, Honeywell uses the following approach to determine savings for this specific measure: Heating Energy Savings $ = ((Heat Loss Rate per square foot of Existing Windows – Heat Loss Rate per square foot of Proposed Windows) x Cost/Therm)/(Boiler Efficiency)) SECTION B: ENERGY CONSERVATION MEASURES 35 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Product Information Manufacturer and Type Equipment Identification Several quality and cost effective manufacturers are available. The following is an example of equipment being utilized. Honeywell and the District will determine final selections. As part of the measure design and approval process, specific product selection will be provided for the District’s review and approval. Changes in Infrastructure The existing single-pane windows will be replaced with double-pane windows that will reduce the amount of heat loss through the windows. Customer Support and Coordination with Utilities Coordination will be required to gain access to the individual rooms for window installations. Environmental Issues Waste Production Energy savings will result from the reduction of heat loss from the uninsulated windows resulting in lower fuel consumptions. The equipment uses no other resources. Any removed parts will be disposed of properly. Environmental Regulations No environmental impact is expected. Resource Use SECTION B: ENERGY CONSERVATION MEASURES 36 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan ECM 4C Roof Replacements Existing Conditions The roof installed at the Branchville School is beyond its useful life and should be replaced. The heat loss and heat gains occur due to a low R-value of the existing roof insulation and will be improved through the replacement with energy efficient roofing materials. Additionally, the rate of infiltration that occurs due to the leakage on the roof around perimeters is also a major cause of energy loss. The upgrade will result in improved savings and comfort for those affected in the building. The District also wishes that this roof be replaced. Overall, through the implementation of this measure the school will reduce its heating fuel usage costs each year. Proposed System Replace a total of approximately 7,800 SF of surface roof system with a smooth-surfaced built-up over ¾" of perlite coverboard over 2" polyisocyanurate insulation (or equal). Energy Savings Methodology and Results Following approach is used to determine savings for this specific measure: Existing Roof Efficiency = Existing U + Existing Infiltration Rate Proposed Roof Efficiency = Proposed U + Proposed Infiltration Rate Energy Savings (Btu) = UAΔTproposed – UAΔTexisting Winter Savings(Therms) = Energy Savings/Boiler Eff./100,000 Interface with Building: The new roof will be constructed to match existing, maintaining contours of the existing building. SECTION B: ENERGY CONSERVATION MEASURES 37 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Energy Savings Methodology and Results The energy savings for this ECM are realized at the building’s HVAC equipment.

SECTION B: ENERGY CONSERVATION MEASURES 38 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan ECM 5A Computer Controllers Existing Conditions During our preliminary energy audit it was brought to our attention that the Frankford Township School and Branchville School have in inventory and are using approximately 225 and 5 desktop personal computers (PC), respectively. Desktop Computers: Energy waste is inherent in large PC networks. While most PCs have energy-saving settings such as stand-by hibernate, and shutdown, over 80% of users disable their low-power settings. Installation of a network-level control over the power settings of all Microsoft Windows-based PCs, from Windows 95 to XP solves this problem by giving the District IT personnel control of these settings. Network managers can easily configure and maintain PC power settings across distributed networks, to automatically send PCs into low-power states as needed. A PC in a school setting wastes 100 to 400 kWh of energy a year by remaining on during unoccupied periods. Ideally, everyone would use the built-in energy saving function on their machine; however, as indicated above these existing energysaving features are rarely enabled. The CRT computer monitors consume 3 times more energy than the flat LCD monitors while they are in an “idle” mode. Proposed System Desktop Computers: Honeywell proposes to install a centralized personal computer power management system to control approximately two hundred twenty-five (225) computers at the Frankford Township School and five (5) computers at the Branchville School. The software by Verdiem called “Surveyor,” enables control of the operation of computers in the schools. Surveyor delivers desktop computer energy management that does not interfere with user or IT needs. Surveyor keeps computers running when users need them, and accurately determines when computers are inactive so they can be powered down through network-wide power consumption and savings reports. Surveyor is a computer energy management solution that analyzes CPU, disk, keyboard, mouse, and application activity before taking power management actions. It is also a solution that is available for both Windows and Mac computers. Surveyor is the ‘green’ software solution for desktop and laptop computers.

Audit mode provides a baseline measure of the energy being consumed, making it easy to determine the true value of the savings generated when Surveyor's features are enabled. Scope of Work Honeywell proposes to purchase and install Surveyor by Verdiem for the network level control of the electric consumption of the computers in the schools. Surveyor is an easy-to-deploy software utility that addresses network energy waste, and reduces operating costs without impacting PC users. Surveyor measures, manages, and minimizes the energy consumed by the network's PC clients through one centralized interface. It provides IT departments with a powerful approach to automate energyefficient “best practices” throughout their networks, while it adds new control and flexibility to traditional PC power management. SECTION B: ENERGY CONSERVATION MEASURES 40 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Honeywell will work with the District to install and rapidly deploy the Surveyor software on the PC network. This single day installation plan will address server and client installation, basic administrative configurations, logical power management profile groupings, and energy consumption reporting. Ongoing technical support and product revisions are also available, with an annual energy audit to ensure maximized energy savings. Predominately, the benefit is the energy savings from the system. It also adds security to the PC network because the most secure PC is the one that is off. Additionally the software provides rudimentary asset inventory views, including last-logged-in user, IP address, machine names, hardware and processor type.

One pair of pumps serves the A wing of the building. Each pump is rated at 7.5 HP. The other two pumps serve the B wing, and each pump is rated at 2 HP. In addition, the C/D boiler room houses one set of two (2) floor-mounted circulator pumps and one set of two (2) pipe-mounted circulator pumps as part of the hot water heating system to serve the hot water unit ventilators and other hot water terminal units. The pair of pipe-mounted pumps serves the C wing of the building. Each pump is rated at 1.5 HP. The other two pumps serve the D wing, and each pump is rated at 3 HP. Each set operates in a lead-lag fashion. All pump motors are standard efficiency. Proposed Solution Honeywell proposes to replace two (2) pump motors with new 7.5 HP high efficiency motors. The scope of work will be as follows: Remove and dispose of old standard efficiency motors. Inspect all couplings and replace as needed. Install new premium efficiency motors on the existing pumps. Align the couplings to EASA standards. Start up of the pumping system. The motors that were identified in the building are listed as follows: Bldg.

The water distribution system is pumped at the constant volume without controlling the water flow. This results in unnecessary excess of pumping power even with a decreased building load. Proposed Solution Honeywell proposes installing Variable Frequency Drives (VFD) on the large hot water loop pump motors to provide more flow controllability and saving electric energy for unnecessary pumping volume. The new VFDs will not only save electrical energy, but will help control building loop temperature especially during shoulder months when thermal loads are at a minimum.

Although the returns are not ideal, this system will be appropriate to this site, and will assist in promoting the “Green Power” image of the District and will be a model for future duplication. Proposed System: The proposed system is a nominal kW-dc system with a DC/AC converter as is listed in the following table: School ID Panel Size (W) Solar System Power (kW) Frankford Township School 270 151 Photovoltaic System Solar cells are converters. They take the energy from sunlight and convert that energy into another form of energy, electricity. Solar cells convert sunlight to electricity without any moving parts, noise, pollution, radiation, or maintenance. The conversion of sunlight into electricity is made possible with the special properties of semi-conducting materials. Semi-Conductors Most solar cells are made from silicon, which is a “semi-conductor” or a “semi-metal,” and has properties of both a metal and an insulator. Solar cells are made by joining two types of semiconducting material: P-type and N-type. P-type semiconductors are manufactured to contain negative ions, and N-type semiconductors are manufactured to contain positive ions. The positive and negative ions within the semiconductor provide the environment necessary for an electrical current to move through a solar cell. Sunlight Converted At the atomic level, light is made of a stream of pure energy particles, called “photons.” This pure energy flows from the sun and shines on the solar cell. The photons actually penetrate into the silicon and randomly strike silicon atoms. When a photon strikes a silicon atom, it ionizes the atom, giving all its energy to an outer electron and allowing the outer electron to break free of the atom. The photon disappears from the universe and all its energy is now in the form of electron movement energy. It is the movement of electrons with energy that we call “electric current.” Sunlight to Electricity A typical solar cell consists of a glass cover to seal the cell, an anti-reflective layer to maximize incoming sunlight, a front and back contact or electrode, and the semiconductor layers where the electrons begin and complete their voyages. The electric current stimulated by sunlight is collected on the front electrode and travels through a circuit back to the solar cell via the back electrode. SECTION B: ENERGY CONSERVATION MEASURES 47 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan PV System Architecture Solar cells interconnected with other system components that ultimately serve a specific electrical demand, or ‘load’. PV systems can either be stand-alone, or grid-connected. The main difference between these two basic types of systems is that in the latter case, the PV system produces power in parallel with the electrical utility, and can feed power back into the utility grid if the onsite load does not use all of the PV system’s output. The 151 kW system proposed here is small enough where the school will consume all of the power generated by the cell. Typical PV System Electronic Information Kiosk The electronic information kiosk brings the building to life for students, faculty, staff and parents. The kiosk terminals are user-driven via interactive touch screens, and can also be configured for tours and group presentations. The kiosk is a centralized source for information about the building, including: A tour of the building's earthfriendly construction materials. Continuous real-time display of the building's solar performance. An introduction to the unique day lighting design that maximizes the use of available sunlight.

SECTION B: ENERGY CONSERVATION MEASURES 50 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan ECM 7B Wind Power Existing Conditions: Small wind electric systems could make a small contribution to the districts energy needs. The issue in the district is the amount of sustainable wind coupled with the wind velocity. The wind velocity is measured by NREL (DOE – National Renewable Energy Laboratory) at 12 mph for this location. Proposed System: Honeywell is recommending a small 6,500 Watt wind turbine at the school for educational purposes. The Honeywell Wind Turbine’s Blade Tip Power System (BTPS) replaces the traditional gear box, shaft and generator of current wind turbine technology. The Honeywell Wind Turbine’s gearless Blade Tip Power System creates a “free wheeling’’ turbine, generating energy from the blade tips (where the speed lies) rather than through a mechanical center gear. By practically eliminating mechanical resistance and drag, the Honeywell Wind Turbine creates significant energy (2,752 kWh/yr in class 4 winds at 33') operating in a greater range of wind speeds (2-42 mph/3-68 km/h) than traditional wind turbines.

Renewable Energy Systems Wind Turbine Proposed System: As stated in ECM 7B, Honeywell is recommending a small 6,500 Watt wind turbine at the Frankford Township School for educational purposes. Honeywell WT 6500 Specifications: Honeywell Gearless Wind Turbine Blade Tip Power System (BTPS) BTPS Permanent Magnet Electric Generator, Patents Pending ETL, UL, CSA, CE, EU Listed (Summer 2010) Installs on Pole, Roof Mount or Commercial Mount Lowest Cost kWh Installed Technology in Class Enclosed Blade Tip Power System Wide Wind Acceptance Angle SECTION B: ENERGY CONSERVATION MEASURES 56 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Acoustic Noise Emissions < 35dB Tip to Tip Blade Dimension 5.7’ (170 cm) 170 lbs ( 77.2 kg) 120 AC 60 Hz 220 AC 50 Hz o KW Plate Power < 2 mph (3 km/h) Cut in Speed, Shut down 42 mph (67.5 km/h) Renewable Electric Generation 2,752 kWh/yr - Class 4 Winds (D.O.E. average US household electric 11,000 kWh/yr) Smart Box Control System includes: Optimal Power Transfer Controller True Sine Wave Inverter Battery Power Management System Wind Direction and Speed Measurement Control System Standard RS485 Communication Port 5 Year Limited Warranty Annual CO2 Displacement 2.2 Tons Product Design Life 20 Years Energy Savings Methodology and Results Savings are based on energy conversion of the wind turbine array and assume a 0.77 DC to AC conversion de-rate factor. Changes in Infrastructure The proposed solar array could reside on the building roof or be ground mounted. Customer Support and Coordination with Utilities Minor support will be required for the interruption of utilities for brief tie-in periods. The District and Honeywell will decide the exact location of solar system installation. Honeywell recommends the installation of a Photovoltaic System for the Frankford Township School. This will generate electric power from solar energy. Although the returns are not ideal, this system will be appropriate to this site, and will assist in promoting the “Green Power” image of the District and will be a model for future duplication. Solar Renewable Energy Proposed System: The proposed system is a nominal 10 kW-dc system with a DC/AC converter as is listed in the following table: School ID Panel Size (W) Solar System Power (kW) Frankford Township School 270 10 SECTION B: ENERGY CONSERVATION MEASURES 57 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Scope of Work: The following scope of work will be provided to achieve the projected savings: Frankford Township School: Photovoltaic System Specifications 37 SUNTECH SOLAR 270 W PV PANELS 1 SMA 56 INPUT PV COMBINERS 1 SMA DC DISCONNECT BREAKERS 1 SUNNY BOY 7000U INVERTERS Miscellaneous Equipment and Services 24VDC WIRING-RHW (#8 AWG) CONDUIT-3" EMT CONDUIT-3/4" EMT 24VDC WIRING-RHW (300 MCM) CONDUIT-2" EMT 208V WIRING-THHN (#4 AWG) CONDUIT-2" EMT UTILITY METERING MANUFACTURER START UP SERVICES Environmental Issues Resource Use Renewable energy will be generated to supplement energy purchased from the electrical utility.

SECTION B: ENERGY CONSERVATION MEASURES 58 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan ECM 8A Kitchen Hood Controllers Existing Conditions The kitchen in the Frankford Township School currently utilizes a constant volume kitchen exhaust hood system. This system operates at full load, even when there is no activity in the kitchen. It also requires operating the exhaust fan at full load. This not only wastes fan energy, but also the heating energy. When the hood is not utilized, an opportunity exists to reduce airflow, and consequently, conserve energy. School ID Kitchen Hood Exhaust Total Frankford Township School 1 1 Proposed System and Scope of Work Honeywell recommends installing an automated DDC control system to control the hood exhaust fan, to ensure the optimal hood performance and to conserve energy. The control system will include the input/output processor, and keypad. Variable frequency drives will be mounted on the utility cabinet. The temperature sensor will be mounted in the exhaust duct and the optic sensor will be mounted inside the ends of the hood. The generalized scope of work is as follows: Install a variable speed drive in a NEMA approved enclosure for the kitchen hood exhaust fan Reconfigure existing power wiring through the variable speed drive Provide a motion sensor and an optical sensor at the kitchen exhaust hood to determine use Provide variable speed drive control points for start/stop, speed and alarm Provide control logic and software to accomplish sequences and incorporate into DDC system Commission control components and sequences, and calibrate control loops SECTION B: ENERGY CONSERVATION MEASURES 59 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Energy Savings Methodology and Results The savings approach is based upon reducing the amount of conditioned air that is being exhausted when there is no cooking taking place. The savings are generally calculated as: Existing Heating BTU & Cost per BTU Cost of Existing Heating Reduction in Heating BTU Cost of Proposed Heating Energy Savings $ = Metered Data from Existing meter readings = Average Site Data $/Therm = Exhaust air cfm x 1.08 x Delta T x Hours the fan is off. = BTU x Cost per BTU = Existing Heating Costs – Proposed Heating Costs The baseline adjustment calculations are included with the energy calculations. Changes in Infrastructure There will be improvements in HVAC equipment and controls for not operating fans continuously. Customer Support and Coordination with Utilities Minor support will be required for the interruption of utilities for brief tie-in periods. Environmental Issues Resource Use Energy savings will result from reduced energy. Waste Production Any removed parts will be disposed of properly. Environmental Regulations No environmental impact is expected. SECTION B: ENERGY CONSERVATION MEASURES 60 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan ECM 8B Walk-In Freezer and Cooler Controllers Existing Conditions In many refrigeration walk-in freezers and coolers, the compressor is oversized and cycles on/off frequently. This compressor cycling results in higher energy consumption and may reduce the life of the compressor. The quantity of freezers and coolers with locations are in the table below: School ID Walk-in Freezers Walk-in Refrigerators Total Frankford Township School 2 1 3 Proposed Solution Under this proposal, Honeywell will install a controller refrigeration sensor at above mentioned school as made by Intellidyne, to reduce the compressor cycles of the kitchen walk-in cooler and freezers. The installation of this ECM will have no negative impact on system operation and freezing of food products. By reducing the cycling, the sensor will improve operating efficiency and reduce the electric consumption by nearly 10% to 20%. Generally, in the event of a compressor failure for the kitchen walk-in freezer; an audible alarm will sound from the panel located outside of the freezer. When this alarm occurs, a bypass switch on the controller located at the condensing unit on the roof should be toggled to place the compressor under normal operation. Once the failure has been corrected, the bypass switch should be toggled back to its original position to resume the controller operation. This control enhancement will save energy through the reduced compressor cycling in the kitchen walk-in cooler and freezer and will extend the operating life of the compressor. Consequently, the compressor will not have to be replaced as often. Intellidyne Features 15 Year full replacement warranty Automatic restart on power failure Surge protection incorporated into circuitry Fully compatible with all energy management systems UL Listed NYSERDA Tested Maintenance Free SECTION B: ENERGY CONSERVATION MEASURES 61 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Intellidyne Benefits Patented process reduces air conditioning electric consumption typically 10% to 20% UL listed, “Energy Management Equipment” Increased savings without replacing or upgrading costly system components “State-of-the-art” microcomputer controller – LED indicators show operating modes Protects compressor against momentary power outages and short cycling Simple 15-minute installation by qualified installer No programming or follow-up visits required Maximum year-round efficiency Reduces maintenance and extends compressor life Fail-safe operation Guaranteed to save energy 15-year replacement warranty for breakdowns or defects Intellidyne’s patented process determines the cooling demand and thermal characteristics of the entire air conditioning system by analyzing the compressor’s cycle pattern, and dynamically modifies that cycle pattern to provide the required amount of cooling in the most efficient manner. This is accomplished in real-time by delaying the start of the next compressor “on” cycle, by an amount determined by the cooling demand analysis. These new patterns also result in less frequent and more efficient compressor cycles.

SECTION B: ENERGY CONSERVATION MEASURES 62 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan ECM 8C Kitchen Sink Pedal Valves Existing Conditions There are sinks in the Frankford Township School kitchen, where the kitchen staff cleans the pots and pans. Following is a count of the sinks at the Frankford Township School: School Total Faucets Frankford Township School 2 Proposed Solution Honeywell is proposing to install pedal valves on the sinks in the kitchen to reduce the water and energy consumption. The savings are derived from the fact that the sink will be running only when there is a person standing in front of the sink with his or her foot on the pedal valve. If that person walks away, water will no longer be running through the faucets and wasting water. With standard faucets, it’s understandable that workers hands are, many times, just too busy to keep turning the water on and off. And frequently, faucets are left trickling or dripping. With pedal valves in place, water is no longer needlessly left running, trickling or dripping. However, when the sinks need to be filled, the latchable pedal, used on prep and pot sinks, provides continuous unattended flow.

SECTION B: ENERGY CONSERVATION MEASURES 64 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan ECM 9A Demand Response Overview Honeywell proposes to utilize a registered Demand Response Curtailment Service Provider (CSP) to provide energy response services to the Frankford Township and Branchville Schools. Through the CSP, the District will participate in the PJM Capacity Market Program and PJM Energy Efficiency Program. These programs are offered through the PJM Regional Transmission Organization (RTO), and Independent System Operator (ISO). The Capacity Market Program allows PJM customers the ability to respond to capacity emergencies when called upon by PJM, and the energy efficiency program pays PJM customers for implementing Energy Conservation measures (ECMs) that result in permanent load reductions during defined hours. Proposed System Honeywell proposes to work with a PJM Regional Transmission Organization (RTO), CSR to implement a Demand Response energy curtailment program which will generate revenue streams for the District. The PJM programs offer the District to the ability to respond to capacity emergencies when called upon by PJM, and benefit from permanent kW load reductions associated with implementing Energy Efficiency (EE) improvements. Honeywell’s Demand Response agent acting as the CSP, will notify the district prior to potential events in order to advise and coordinate load curtailment participation in accordance with RTO program requirements, and will work with the District to benefit from EE Improvements. The PJM Markets are further described below. PJM Capacity Market Program Capacity represents the need to have adequate resources to ensure that the demand for electricity can be met. For PJM, that means that a utility or other electricity supplier, load serving entity, is required to have the resources to meet its consumers’ demand plus a reserve amount. Electricity suppliers, load serving entities, can meet that requirement by owning and operating generation capacity, by purchasing capacity from others or by obtaining capacity through PJMs capacity market auctions. PJM operates a capacity market, called the Reliability Pricing Model (RPM). It is designed to ensure that adequate resources are available to meet the demand for electricity at all times. In the RPM, those resources include not only generating stations, but also demand response actions and energy efficiency measures by consumers to reduce their demand for electricity. PJM must keep the electric grid operating in balance by ensuring there is adequate generation of electricity to satisfy the demand for electricity at every location in the region both now and in the future. PJM’s markets for energy and ancillary services help maintain the balance now while the PJM market for capacity aims to keep the system in balance in the future. Resources, even if they operate infrequently, must receive enough revenue to cover their costs. SECTION B: ENERGY CONSERVATION MEASURES 65 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Payments for capacity provide a revenue stream to maintain and keep current resources operating and to develop new resources. Investors need sufficient long-term price signals to encourage the maintenance and development of generation, transmission and demand-side resources. The RPM, based on making capacity commitments in advance of the energy need, creates a long-term price signal to attract needed investments for reliability in the PJM region. The PJM Energy Efficiency Program Energy efficiency measures consist of installing more efficient devices or implementing more efficient processes/systems that exceed then-current building codes or other relevant standards. An energy efficiency resource must achieve a permanent, continuous reduction in demand for electricity. Energy efficiency measures are fully implemented throughout the delivery year without any requirement of notice, dispatch, or operator intervention. A demand response resource can reduce its demand for electricity when instructed; this means PJM considers it a “dispatchable resource”. A demand response resource can participate in the RPM market for as long as its ability to reduce its demand continues. A demand response resource must be willing to reduce demand for electricity up to 10 times each year when called for a reduction. In a year without any reduction calls, the demand response resource is required to demonstrate the ability to reduce demand for electricity during a test of reduction capability. Data will be submitted by the demand response resource to prove compliance with reductions from actual calls or reductions from capability tests. An energy efficiency resource is one that reduced their demand for electricity through an energy efficiency measure that does not require any additional action by the consumer. Energy Savings Methodology and Results The energy savings for this ECM are realized due to savings in electric usage during scheduled load shedding periods. Changes in Infrastructure None Customer Support and Coordination with Utilities Minimal coordination efforts will be needed to reduce or limit impact to building occupants. Environmental Issues Resource Use Energy savings will result from reduced Electric Usage during scheduled periods. Waste Production None.

SECTION C: FINANCIAL ANALYSIS 2 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Overview In the development of an Energy Savings Plan (ESP) in accordance with PL 2009, c.4, it is important to identify energy conservation measures (ECM’s) that may be implemented now or at some point in the future. The law outlines the responsibility to identify the opportunities and then proceed forward based on the needs and requirements of the school district, while building a self funding comprehensive project. If an ECM is not identified as part of this ESP, it cannot be implemented as part of an Energy Savings Improvement Program (ESIP) without a board amended change to the ESP. It is the intent of this financial analysis to identify ALL potential ECM’s within the Frankford School District as part of a comprehensive ESP. It does not mean that all the ECM’s need to be or can be implemented at this time if the requirements of the legislation are not met. However, so long as the ECM is part of this plan, it may be implemented at a later date as additional funding becomes available or technology changes in order to provide an improved financial return. Should the Board of Education adopt this ESP, the next step is to develop a priority list of ECM’s complete with a financial return that meets the requirement of the law and satisfy’s the energy and operational goals of your district. A collaborative project development agreement (PDA) between Honeywell and the Frankford School District will be developed to establish the minimum criteria for the project as well as outline a specific time line to implement the program. The following spreadsheets are part of this financial overview. Simple Payback - ALL – This is an overview of the projects we identified by ECM with cost and savings identified per project. It is important to understand that economies can be achieved by combining projects; however for the purpose of clarity we have separated each. Simple Payback – SAMPLE Recommended – This is an overview of the projects we recommend that will meet the requirements of the law. Financial Cash Flow – SAMPLE - This is a 15 year cash flow with the costs, savings and financing for recommended projects identified in this plan. As ECM’s are prioritized, selected and projects are combined, this cash flow will change. However, the law requires that all savings must pay for costs, including financing.

SECTION E: MEASUREMENT, VERIFICATION AND GUARANTEE OF ENERGY SAVINGS / RECOMMENDED MAINTENANCE 2 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Honeywell has proven capabilities in applying measurement and verification methods appropriately to develop and verify energy baselines. Honeywell has also demonstrated abilities to conduct postinstallation and regular interval verification inspections to confirm guaranteed energy savings. Honeywell will develop savings methodologies that follow current industry practice, such as outlined by the New Jersey Board of Public Utilities (NJBPU), Federal Energy Management Program’s (FEMP) M&V Guidelines: Measurement and Verification for Federal Energy Projects. References to M&V protocols from the International Performance Measurement and Verification Protocol (IPMVP), ASHRAE Guideline 14 and the Air-Conditioning Refrigeration Institute (ARI) are used to further qualify the M&V plan. Honeywell uses a variety of the M&V options as defined in the NJBPU Guidelines, as the basis for selecting methodologies to evaluate each Energy Conservation Measure (ECM) technology category identified and implemented through a performance contract. In all performance contracting agreements, Honeywell discusses the M&V options available for savings verification with the District during the audit phase. The following tables are used as benchmarks for these discussions. In all cases, a mutual decision is reached on the M&V protocols that will be used for each ECM. For each implemented ECM, energy savings are derived from a mutually agreed-upon, site-specific M&V plan. The M&V plan will provide an explanation of the objectives for M&V activities, which will comply with the steps outlined in the NJBPU Guidelines. The plan will also define the parameters to be monitored, and a detailed description of the usage groups, population sizes and sample sizes that are proposed for each ECM. Definition of the baseline, post- installation, and regular interval parameters associated with each ECM are also defined in the M&V plan. SECTION E: MEASUREMENT, VERIFICATION AND GUARANTEE OF ENERGY SAVINGS / RECOMMENDED MAINTENANCE 3 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan An M&V Specialist will work in close concert with the Performance Contracting Engineers (PCE’s), the project installation team, and your District to ensure that accurate information is obtained.

It continues throughout the term of the contract guarantee, and can continue as an ongoing service at the conclusion of the guarantee period. Energy auditing is a process, but not so rigidly structured that it is devoid of independent decision making. It is a mistake to think that the energy auditing process is a series of tasks, performed sequentially the same way every time. Honeywell looks at energy auditing as a systematic means of analyzing and reporting results, and deciding which actions to take to meet the requirements of specific contracts. The following summarizes the energy auditing process. Energy audits can be provided on a quarterly, semi-annual or annual basis as determined by the District. 1. Data about a building’s operation, utility costs, and usage is assembled to establish the baseline energy consumption model. If changes did occur, adjustment calculations will need to be done and the district will need to approve the adjustment. 2. Data is analyzed to determine base loads and to provide a check of savings figures. (i.e. are energy savings figures realistic?) 3. Requirements of the Honeywell scope & internal Risk Review Process are completed. All personnel involved in the Review Process approve the project, including the Honeywell Measurement & Verification Specialist Lead. 4. Industry standard energy engineering calculations and methods are utilized and are part of the contract documents. All calculations will be reviewed to satisfy the requirement that these must be a reasonable representation, or model, of facility energy consumption before and after the energy retrofit projects are completed. 5. The Project Manager will help ensure performance compliance, and will be responsible for proper installation, operation, and maintenance of the ECMs in accordance with design and contractual parameters. This includes ensuring that verification data is accurately collected and analyzed, and that measuring equipment is calibrated in accordance with prescribed standards. Measurement and Verification Options Options A, B, C, and D are four options which contain measurement guidelines consistent with those defined in the September 2000 version of the FEMP M&V Guidelines. The four options were created to provide flexibility in the determination of savings. This flexibility allows one to arrive at an optimum position regarding increased cost for decreased uncertainty in the determination the realized savings. The District’s expectations and specific features of the campus facilities will dictate which particular option (A, B, C, or D) will be the most reasonable and cost-effective solution, providing accountable and verifiable results. Option A – No Metering / Spot Metering Requires verification that the ECM has the potential to perform and to generate savings. Verification of performance (savings) may be stipulated. Performance verification techniques for Option A include engineering calculations, spot measurements or stipulated (mutually agreed-upon) values. Field audits will be required in most cases with the application of Option A. SECTION E: MEASUREMENT, VERIFICATION AND GUARANTEE OF ENERGY SAVINGS / RECOMMENDED MAINTENANCE 5 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Spot metering will entail taking instantaneous measurement of volts, amperes, kVA, pF and kW. Measurements will be taken one time only. The type of data collection devices include: run-time loggers, kW/kWh transducers, occupancy data loggers, flow meters, and digital hygrometers. Measurement equipment will be calibrated in accordance with the manufacturer’s specifications. Option B – Regular Interval / Continuous Metering Requires verification that the ECM has the potential to perform. It also requires verification of actual performance by end-use system or device. Verification of performance (savings) is required with this option. Performance verification techniques include engineering calculations, spot and short-term metering or continuous metering. Development of a sampling plan may be required when using Option B as measurement and verification option. Short term metering will be conducted for a minimum period of three weeks. The data collected may be used to extrapolate after retrofit annual energy demand and consumption profiles. Continuous data collection is done by totalization and trending consumption of energy consuming systems or end-use devices through an energy management system (EMS) or placement of an additional meter (sub-metering). Option C – Utility Bill Analysis Requires verification that the opportunity has the potential to perform, as well as verification of actual performance via whole building analysis. Verification of potential to perform (generate savings) and verification of performance (savings) is required with this option. Performance verification techniques include utility meter billing analysis possibly with computer simulation. Utility bill analysis consists of the review of two years of utility data to determine and establish the 365-day baseline. The baseline model is developed from utility bills and independent variables such as weather, operating schedules, and occupancy patterns. Utility data is entered into a baseline-modeling program such as Metrix that performs utility billing analysis using multivariate regression. Adjustments to the baseline that may be required are mutually agreed upon. The Metrix utility accounting system is a third party software package designed by SRC Systems, Inc. in Berkley, California. The utility accounting system is used to track, budget, and verify utility operating costs and savings. Option D – Computer Simulation Requires verification that the opportunity has the potential to perform, as well as verification of actual performance by end-use systems or devices. Verification of potential to perform (generate savings) and verification of performance (savings) is required with this option. The performance verification technique is a computer simulation analysis. Option D provides a measurement and verification protocol for those ECMs which involve building envelope improvements, upgrades/expansions of existing energy management systems, ECMs which are variable load projects, or those ECMs which have interactive effects. Computer simulation will involve developing models by such building simulation programs as DOE 2.1e, Carrier HAP, or Trace 600. SECTION E: MEASUREMENT, VERIFICATION AND GUARANTEE OF ENERGY SAVINGS / RECOMMENDED MAINTENANCE 6 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Baseline Adjustments Regular Adjustments Every time an energy audit (determination of energy savings) is performed, the “regular” adjustments are calculated and applied to the baseline usage and cost data. These are adjustments for weather, billing period length and utility rates. These adjustments are usually performed through energy accounting software such as Metrix. Periodic Adjustments Periodic adjustments are performed separately from the energy accounting software. Often these adjustments involve the application of building energy simulation tools and techniques. Because the periodic adjustments are performed separately and cannot be developed automatically through the energy accounting software, these adjustments are recalculated only when it appears that conditions have changed enough to warrant a recalculation. Combining and Applying Adjustments Once developed, the regular usage adjustments and periodic usage adjustments are combined with an Excel spreadsheet to arrive at the total month by month usage adjustment, which accurately reflects what the baseline period usage would have been under current period conditions. The applicable utility rate changes are then applied to arrive at what the baseline period energy costs would have been under current period conditions and rates. This figure is then compared against the actual current period energy cost to determine the amount of energy cost savings which has occurred. Audit Adjustment Methodologies The Energy Analyst will determine actual annual energy savings by comparing the energy consumed during each guarantee year, with the base year, adjusted as described below. The purpose of base year adjustments is to ensure that the annual reconciliation is quantified on a comparison of energy consumption for each type of fuel. Some typical adjustments are related to the following: Added mechanical or HVAC equipment Additional square footage Office equipment (computers, copiers, etc.) Changes in occupancy Equipment failures Specific adjustment methodologies are as follows: Billing Period Adjustment Adjustment to the monthly comparison periods will reflect same start date and equal number of days being compared. Weather Adjustment Adjustment to the base-year will reflect weather differences between the base-year or period and current year or period. SECTION E: MEASUREMENT, VERIFICATION AND GUARANTEE OF ENERGY SAVINGS / RECOMMENDED MAINTENANCE 7 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Square Footage Adjustment Additions or permanent closures of floor space will be accounted for and factored into the comparison of the base-year and current period. Utility Rate Adjustment The energy audit methodology will use the rate schedules and charges documented in the contract as they apply to the current monthly bills. Operational and Occupancy Hours Adjustment Additions to or reductions in the sizes or types, as well as hours of operation of use for equipment will be accounted for and factored into the comparison of base-year and current period, based upon standard engineering calculations and data measured electronically for this purpose. Significant changes in conditioning set points will also be accounted for and adjusted. Demand Charges Adjustment Demand charges incurred as a result of equipment usage not controlled or operated for energy conservation under the project scope will be identified adjusted for in the annual savings reconciliation. Audit Adjustment Procedures If it is necessary to make baseline adjustments, the following adjustment procedures will be followed. The Energy Analyst will estimate (using appropriate engineering calculations) how much energy was used due to the changed condition. The calculations will be based upon such factors as installed kW, BTU input, efficiency, runtime, etc. For Example: If the customer installed a new computer lab subsequent to the baseline year, and it has 30 PCs at 300 watts each and it runs 30 hours per week, the calculation would show: 30 PCs X 300 Watts = 9 kW (Peak load increase) 9 kW X 30 hrs per week = 270 kWh per week 270 kWh X 4 weeks = 1080 kWh per four week period. An increase usage of about 1,080 kWh per 4-week period, plus an additional peak load of 9 kW. The Energy Analyst will document all changes in the audit: Equipment sizes Operating hours Energy calculation used Results This information will be shown as adjustment documentation that is a permanent part of the audit file, and is used in preparing energy audits. It will be tracked throughout the term of the contract. SECTION E: MEASUREMENT, VERIFICATION AND GUARANTEE OF ENERGY SAVINGS / RECOMMENDED MAINTENANCE 8 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Without such adjustments, increased energy usage at the facility would reduce the value of the cost avoidance calculated by Metrix. This is because cost avoidance is based on adjusted energy reduction-the difference between adjusted baseline energy consumption and current energy consumption. If the baseline is not adjusted upward to account for additional energy consumption (that Honeywell has no control over, and which was not present during the base year), the adjusted energy reduction will be less than the amount we had based our savings guarantee on. The customer must agree to and understand all adjustments at the time of audit delivery (quarterly, semiannual, or annual). Their agreement and acceptance of the audit indicates their acceptance of the audit methodology, including all adjustments (due to changes in weather, changes in occupancy, addition of new equipment, etc.). ECM-based Measurement and Verification (M&V) Audit Adjustments ECM-based Measurement and Verification (M&V), is another credible way to demonstrate energy savings. The technique has evolved considerably with the adoption of automated data collection tools (such as building automation systems with direct digital controllers, programmable meters and dataloggers) in facilities. ECM-based measurement and verification is the derivation of energy savings (and the associated value of those savings) from measured data collected before and after the implementation of the energy conservation measures (ECMs). It can also apply to demand savings, and the associated value of those savings. A form of this technique can be used for supply-side strategies that reduce the cost of the energy consumed (examples are cogeneration, thermal storage, and rate-switching or fuel-switching projects). ECM Based M&V Audits are different from the utility bill auditing methods, which uses data obtained from the monthly bills. With the utility bill auditing method, it can be difficult to impossible to quantify the value of adjustments to baseline energy consumption, especially in a facility with few meters and many energy events that are not measured. In ECM-Based Measurement and Verification, the ongoing energy savings are measured and calculated using the same calculation models and measurement methods that were used to determine the baseline energy savings. The Energy Analyst and the Engineer work closely together to ensure that the audit methodology matches the methodology used for the original energy savings estimates. When ECM-based Measurement and Verification is used, the following five components are essential for demonstrating guaranteed energy savings: 1. 2. 3. 4. 5. Pre-retrofit energy use profile (baseline). Post-retrofit time-of -use measurement. Post-retrofit energy and/or demand measurement (directly measured or derived from other measured variables). Post-retrofit value of energy and demand saved. Acceptable sampling plan. SECTION E: MEASUREMENT, VERIFICATION AND GUARANTEE OF ENERGY SAVINGS / RECOMMENDED MAINTENANCE 9 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan In Utility Bill Auditing, Honeywell uses energy consumption and demand information for the entire facility to develop the baseline energy use. In ECM-Based Measurement and Verification, Honeywell will model the energy use and demand associated with each individual ECM implemented. Dollar Savings Calculations Honeywell’s policy to assigning a dollar value to savings is to first identify the consumption reduction of the particular utility. When the consumption reduction is identified, the corresponding cost of the utility unit is used to determine the value of the savings. The savings is based upon units of energy and the dollar value is associated with agreed upon based year per unit costs for oil, electric, gas, and water. Maintenance Savings For each improvement measure a list of potential maintenance savings or benefits will be developed. This list will be reviewed with Frankford School District to determine if any maintenance or material dollars can be applied to help justify specific investments identified in the audit. Guaranteed Savings The approach that Honeywell utilizes in this asset management program includes two key components: a performance guarantee and financial savings. Honeywell guarantees the Customer that all installations and work performed are subject to final inspection and Customer’s acceptance. This procedure ensures all work will be to the level of quality the Customer expects. Honeywell also guarantees it will meet the objectives mutually defined with the Customer. Honeywell takes its commitment to partner with the Customer for the life of the contract seriously, and looks forward to a successful, long-term partnership. Honeywell will provide a cost avoidance guarantee to the Customer. It will contain both energy and operational savings based on data from your utility bills, building operation, and budget information. The energy savings guarantee is structured to accommodate changes in utility rates, changes in building structures, changes in building occupancy patterns, and weather variances. In simple terms, this means that Honeywell guarantees a level of energy consumption based on conditions as they existed in the base year. Any changes or modifications to the buildings operating conditions need to be communicated on a regular basis. An example of this would be constructing an addition on a building. This addition would increase your energy baseline and would need to be documented. The energy guarantee is documented with any assumptions in our final contract and is shown in Attachments F & G, in our contract. Honeywell considers the guarantee to be the cornerstone of our service to you. To be considered a performance contract an energy guarantee is a required component. The basis of an energy performance contract is that the majority of risk is shifted from the customer to the vendor. The strength of the Guarantee is only as good as the Company backing it and their financial solvency. SECTION E: MEASUREMENT, VERIFICATION AND GUARANTEE OF ENERGY SAVINGS / RECOMMENDED MAINTENANCE 10 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Honeywell has entered into over 4,300 energy performance contracts and has had over $1 Billion in energy guarantees. We have the strength and background to support the Customer for the long term. It is important to make a distinction between Honeywell’s guarantee and other possible savings assurance structures. Honeywell guarantees that the Customer will benefit from 100% of the cost savings, reductions, and cost avoidance realized. Alternate structures that may be proposed by other vendors include having the Customer share savings with the vendor, effectively reducing both the scope achievable under the savings captured by the Customer and limiting the overall financial benefits. The guarantee is generally structured to cover the ongoing monitoring and auditing. Honeywell will work with the Customer to determine the scope of ongoing maintenance services required in order for the guarantee to remain in place and for the savings to be achieved.

Honeywell offers a uniquely comprehensive portfolio of services – one of the most extensive in the industry. As part of the Energy Savings Plan, we recommend the following services for consideration to ensure achievement of the Enrgy Savings outlined in this plam According to the NJ ESIP program, all services are required to be bid by the school district for services as desired. Based on Honeywell’s vast service organization, we are uniquely qualified to develop design specification for the public bidding according to NJ Law. Honeywell strongly believes that the long-term success of any conservation program is equally dependent upon the appropriate application of energy savings technologies, as well as solid fundamental maintenance and support. One of the primary contributors to energy waste and premature physical plant deterioration is the lack of operations, personnel training and equipment maintenance. Honeywell recommends routine maintenance on the following systems throughout the district for the duration of an energy guarantee of savings Maintenance, Repair and Retrofit Services: Mechanical Systems Building Automation Systems Temperature Control Systems Air Filtration Honeywell will work with the School District to evaluate current maintenance practices and procedures. This information will be the basis of a preventive maintenance and performance management plan designed to maximize building operating efficiencies, extend the useful life of your equipment and support the designed Energy Savings Plan.

SECTION F: DESIGN APPROACH 2 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Design Approach In accordance with the ESIP PL 2009, c.4 as part of the implementation process, an agreement between your school district and Honeywell will determine the energy conservation measures (ECM’s) to be implemented. Honeywell is then required to secure the services of a New Jersey Licensed Engineering firm and/or Architectural firm in order to properly comply with local building codes, compliance issues and New Jersey Public contract law. Specifications will be designed and developed to exact standards as recommended by Honeywell in order to achieve all savings outlined in this Energy Savings Plan (ESP). Once specifications are completed, Honeywell will publicly solicit contractors capable of meeting the requirements of the specification for each trade. However, even before the completion of the bidding process, Honeywell will be providing construction and project management services in order to maintain a schedule in order to meet the School District’s expectations. An overview of these activities and functions are detailed below. Project Management – Construction Management Planning A Honeywell Project Management Plan defines plans and controls the tasks that must be completed for your project. But more than task administration, our project management process oversees the efficient allocation of resources to complete those tasks. Each project and each customer’s requirements are unique. At Honeywell we address customer needs through a formal communication process. This begins by designating one of our project managers to be responsible for keeping the customer abreast of the status of the project. As the facilities improvements portion of the partnership begins, the Project Manager serves as a single focal point of responsibility for all aspects of the partnership. The Project Manager monitors labor, material, and project modifications related to the Frankford/Honeywell partnership and makes changes to ensure achievement of performance requirements in the facilities modernization component. The Project Manager regularly reviews the on-going process of the project with the customers. The Project Manager will develop and maintain effective on-going contact with the District and all other project participants to resolve issues and update project status. There are several challenges in this position. The Project Manager must staff the project and create a work force capable of handling the technologies associated with the project and plan for and use these personnel to achieve optimum results focused on occupant comfort and guarantee requirements. The project management process applies technical knowledge, people and communication skills, and management talent in an on-site, pro-active manner to ensure that our contract commitments are met on time, within budget, and at the quality you expect. SECTION F: DESIGN APPROACH 3 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan There are ten distinctive phases of the project management process: Construction Management Prior to any work in the buildings, our Project Manager, Jim Freeman will sit down with your administrative and building staff to outline the energy conservation upgrades that we will be installing in the buildings. We will discuss proper contractor protocol of checking in and out of the buildings on a daily basis, wearing identifiable shirts, and checking in with your facilities staff. We will coordinate certain projects for different times of the day so we do not interrupt the building and learning environments. Our staff will work a combination of first and second shifts to accomplish the pre-set implementation schedule. Communication is the key success factor in any construction management plan, and our project manager will be the key focal point during the installation process. Our team will prevent schedule slippages by continuously tracking the location of all equipment and components required for the project. We make sure all equipment and components will be delivered on time prior to the scheduled date of delivery. Our thorough survey, evaluation and analysis of existing conditions, performed prior to the commencement of construction, will also prevent schedule slippages. SECTION F: DESIGN APPROACH 4 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Subcontracting As indicated above, Honeywell would develop detailed specifications with a NJ Licensed Engineering firm for each ECM project accepted by the School District. The contractor would need to be able to meet all requirements of New Jersey Public contracting laws regarding insurance, bonding, and performance requirements. Typical areas that are subcontracted are as follows: Electrical Installation Water Conservation (Plumbing) HVAC Installation Renewable technologies Associated General Contracting specialty items to support the project etc., (ceilings, windows, concrete, structural steel, roofing, demolition and removal of equipment, painting and rigging) Honeywell uses the following guidelines in hiring subcontractors to perform work on our projects. Firm’s Qualifications and WBE/MBE Status Firm’s Financial Stability Ability to perform the work within the project timeline Price Ability to provide service on the equipment or materials installed over a long period of time. Approval of subcontractors that Honeywell proposes to use lies with the School District. Installation Standards When Honeywell designs a solution, we take into account current and future operations. For any upgrades we install, we follow building codes/standards, which dictate certain standards for energy or building improvements. Listed in tables following this section are standards for building design. During the life of the agreement, there is a partnership approach to maintaining these standards for reasons of comfort and reliability. For lighting our standard is generally to meet or exceed current light levels, achieving the relevant standards wherever possible. In the case of lighting upgrades, we recommend that a group re-lamping of lamps be done around five years after the initial installation depending upon run times. Your building facility staff, on an as needed basis, can complete normal routine maintenance of lamps and ballasts. This maintains the quality of the lighting levels, and color rendering qualities of the lamps. Space temperatures will be set by the energy management system and local building controls, and will be maintained on an annual basis. Flexibility will be maintained to regulate space temperatures as required to accommodate building occupant needs. SECTION F: DESIGN APPROACH 5 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Your facility staff and building personnel will do the operation of the energy management system with ongoing training from Honeywell. Therefore, both the District and Honeywell will maintain the standards of comfort. The comfort standards will be maintained throughout the life of the agreement through sound maintenance planning and services recommended as part of this ESP. With regard to ventilation, Honeywell will upgrade ventilation to meet current standards in those areas where our scope of work involves upgrades to or replacement of systems providing building ventilation. We generally will not upgrade ventilation in those areas where our work doesn’t involve the upgrade or replacement of systems or equipment providing ventilation to a building or facility. Heating and Cooling Standards Heating Temperatures 68-70° F Cooling Temperatures 75° F Unoccupied Temperatures 55-60° F Lighting Standards: Recommended Light Levels Task Area Foot-candles Corridors/Stairways/Restrooms 10-20 Storage Rooms 10-50 Conference Rooms 20-50 General Offices 50-100 Drafting/Accounting 100-200 Areas with VDTs 75 Classrooms 50-55 Cafeterias 50 Gymnasiums 30-50 SECTION F: DESIGN APPROACH 6 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Honeywell uses a variety of in-house labor as well as subcontractors to install the energy conservation measures. We have on staff trained professionals in fire, security, energy management systems, all temperature control systems, and HVAC. However, according to the ESIP law, all trades will be publicly bid except for specific controls applications. Honeywell will also utilize the control system that is already in the facility so long as it can achieve the performance goals of the School District. Listed below is a sampling of some of the disciplines that would apply to the District, but is not all encompassing.

Honeywell will work with the School District to review your hazardous material reports, and will identify the areas where work will be completed so that the District can contract to have any necessary material abatement completed. Honeywell can help schedule or coordinate waste removal, but cannot contract for or assume responsibility for the abatement work. Honeywell also has the capabilities to assist the District in working with the EPA under compliance management issues. We also develop and manufacture automated systems to track and report a wide variety of environmental factors. SECTION F: DESIGN APPROACH 7 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan Commissioning Honeywell provides full commissioning of energy conservation measures (ECM’s) at the request of the customer. We will customize this process based on the complexity of Energy Conservation Measures and make our services available to the school district appointed commissioning agent as directed. Upon project acceptance by the Frankford School District, the assigned Commissioning Agent (CA) will be responsible for start-up and commissioning of the new equipment and systems to be installed during the project. This will include verifying that the installed equipment meets specifications, is installed and started up in accordance with manufacturer’s recommendations, and operates as intended. A commissioning plan will be prepared that describes the functional tests to be performed on the equipment and the acceptance criteria. Prior to customer acceptance of the project, the CA submits the final commissioning report containing signed acceptance sheets for each ECM. Signed acceptance sheets are obtained upon demonstrating the functionality of each ECM to an agency-appointed representative. Honeywell provides training for agency operators and personnel as needed when each ECM is completed and placed into service. All training is documented in the final commissioning report. Financing the ESIP Upon adoption of this ESP, Honeywell will explore and obtain financing arrangements to fund the implementation phase of the process. Several options are available under the ESIP act PL 2009, c.4 An ESIP can be financed through energy savings obligations. The term refers to the two primary financing tools, debt and lease-purchase instruments. Each of these options is discussed below. Financing an ESIP is based on the principle, that with certain exceptions (i.e., audit and verification costs), the cost of the improvements (including planning, design, engineering, construction, etc.) will be paid through the value of reduced energy costs. Using the BPU protocols for calculating savings, energy costs, and inflation as standards across all local units is a critical component of the ESIP. Energy savings obligations shall not be used to finance maintenance, guarantees, or the required third party verification of energy conservation measures guarantees. Energy saving obligations, however, may include the costs of an energy audit and the cost of verification of energy savings as part of adopting an energy savings plan or upon commissioning. While the audit and verification costs may be financed, they are not counted in the energy savings plan as a cost to be offset with savings. In all cases, the maturity schedules for energy savings obligations must not exceed the estimated useful life of the individual energy conservation measure. SECTION F: DESIGN APPROACH 8 Confidential & Proprietary Frankford Township School District District‐Wide Energy Savings Plan An ESIP can also include installation of renewable energy facilities, such as solar panels. Under an energy savings plan, solar panels can be installed, and the reduced cost of energy reflected as savings. The law also provides that the cost of energy saving obligations may be treated as an element of the local unit’s utility budget, as it replaces energy costs. Debt Issuance The law specifically authorizes municipalities, school districts, counties, and fire districts to issue refunding bonds as a general obligation, backed with full faith and credit of the local unit to finance the ESIP. Because an ESIP does not effectively authorize new costs or taxpayer obligations, the refunding bond is appropriate and proper, as it does not affect debt limits, or in the case of a board of education, voter approval. The routine procedures for refunding bonds found in the Local Bond Law and Public School Bond Law would be followed for issuance of debt, along with any required Bond Anticipation Notes as authorized pursuant to law. With regard to bonds for public schools, the Department of Education (DOE) has concluded that debt financed ESIP projects are not covered by State aid for debt service or a “Section 15 EFFCA Grant” as there is no new local debt being authorized. Lease Purchase Financing A local unit can enter into a lease-purchase agreement to implement an ESIP with a single investor lease or certificates of participation. The agreement can be entered into directly by the local unit, with ESCO, other private financing party, or through a county improvement authority or the New Jersey Economic Development Authority. The following additional requirements affect ESIP leasing: i. Ownership of the energy savings equipment or improvements shall remain with the third party financing entity until all lease payments have been made or other requirements of the financing documents for the satisfaction of the obligation are met. If improvements are made to facilities owned by the local unit, the local unit will have to enter into a ground lease of the facilities to be leased back to the local unit. ii. The duration of a lease-purchase agreement shall not exceed 15 years, except that the duration of a lease purchase agreement for a combined heat and power (CHP) or cogeneration project shall not exceed 20 years. CHP and cogeneration facilities are specialized types of energy conservation measures. The law supersedes the existing 5 year limit on lease-purchase financing for these types of projects. iii. Any lease purchase agreement may contain a clause making it subject to the availability of sufficient funds as may be required to meet the extended obligation; or a non-substitution clause maintaining that if the agreement is terminated for non-appropriation, the contracting unit may not replace the leased equipment. While normal for these types of leases, the optional nature in the law permits the transaction attorney to negotiate them as terms of a lease agreement.
