Cost and savings calculations for a given measure were estimated to within ±20%, and are based on data obtained from the owner, data obtained during site observations, professional experience, historical data, and standard engineering practice. Cost data does not include soft costs such as engineering fees, legal fees, project management fees, financing, etc. A thorough walkthrough of the school was performed, which included gathering nameplate information and operating parameters for all accessible equipment and lighting systems. Unless otherwise stated, model, efficiency, and capacity information included in this report were collected directly from equipment nameplates and /or from documentation provided by the owner during the site visit. Typical operation and scheduling information was obtained from interviewing staff and spot measurements taken in the field. New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit iii

5 1.0 EXECUTIVE SUMMARY This energy audit is performed by CHA in connection with the New Jersey Board of Public Utilities Local Government Energy Audit Program for the Parsippany-Troy Hills Board of Education. The purpose of this report is to identify energy savings opportunities associated with major energy consumers and inefficient practices. This report details the results of the energy audit conducted for: Building Name Troy Hills Elementary School Address 509 South Beverwyck Road Parsippany, NJ Square Construction Feet Date 36,954 Original:1967 The potential annual energy and cost savings for each energy conservation measure (ECM) is shown below in Table 1. Each individual measure s annual savings are dependent on that measure alone, theree are no interactive effects calculated. There are threee options shown for Lighting ECM savings; only one option can be chosen. Incentives shown (if any) are based only on the SmartStart Incentive Program. Other NJBPU or local utility incentives may also be available/ applicable and are discussed in Section 5.0. Each measure recommended by CHA typically has a simple payback period of 15 years or less to be consistent with the requirements of thee Energy Savings Improvement Plan (ESIP) which has a maximum payback period of 15 years. Occasionally, we will recommend an ECM that has a longer payback period, based on the need to replace that piece(s) of equipment, such as a boiler for example. If the recommended measures are implemented a total potential annual savings of $4,900 may be realized with an average simple payback period of 4.0 years.

7 2.0 INTRODUCT TION AND BACKGROU UND The Troy Hills Elementary School is a 36,954 square foot building consisting of one floor. The building was constructed in The school includes the following spaces: classrooms, offices, multi-purpose room, storage, toilet rooms, media center and a mechanical room. The school hours of operation are from 8:45 AM 3:25 PM Monday through Friday. The school has approximately 287 K-5 studentss and 55 faculty and staff members. The school has 153 computers.

8 3.0 UTILITY New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit Page Utilities include electricity and natural gas. Electricity is delivered and supplied by Central Power and Lighting (JCP&L). District personnel indicated that electricity bills for Troy Hills Elementary School were not available forr analysis because JCP&L has failed to send them bills for this period. Therefore electrical data from Rockaway Meadow Elementary School was used to establish a rate because the schools weree built around the same time and have almost identical construction. Natural gas is delivered by New Jersey Natural Gas and supplied by Compass through a Consortium. The school district is charged for water/ sewer which are provided by the Parsippany-Troy Hills municipal water utility. For the 12-month period ending in October 2012, thee utilities usage for the building was as follows: Table 2: Actual Cost & Site Utility Usage Electric (Estimated) Annual Usage Annual Cost Blended Rate Supply Rate Demand Rate Peak Demand Min. Demand Avg. Demand 175,280 22, Natural Gas kwh/year $ $/kwh $/kwh $/kw kw kw kw Annual Usage Annual Cost Rate 23,270 22, Water / Sewer Therms/year $ $/Therm Annual Usage Annual Cost Rate 373,600 7, Gallons/year $ $/Gallon Electrical usage was generally lower in the summer months when the school is unoccupied. Natural gas consumption was highestt in winter months for heating. See Appendix A for a detailed utility analysis. 4

The supply portion is open to competition, and customers can shop around for thee best price for their energy suppliers. The electric and natural gas distribution utilities will still deliver the gas/ electric supplies through their wires and pipes and respond to emergencies, should they arise regardless of where those supplies are purchased. Purchasing the energy supplies from a company other than your electric or gas utility is purely an economic decision; it has no impact on the reliability or safety of the service. Additional information on selecting a third party energy supplier is available here: http: // See Appendix A for a list of third-party energy suppliers licensed by the Board of Public Utilities to sell within the building s service area. 5

10 4.0 EXISTING CONDITIONS & AREAS OF ENERGY OPPORTUNITY Energy conservation measures (ECM s) are energy savingss recommendations that typically require a financial investment. Energy savings can be in the form of electrical demand (KW= kilowatts), electrical usage (Kwh=Kilowatt-hour), natural gas (Therms=100,0000 BTU), propane gas (Gallons= =91,650 BTU), Fuel Oil (Gallons =138,700 Btu) and water (KGAL=1000 gallons). These recommendations are influenced by the timee period thatt it takes to break even referred to as Simple Payback. Simple payback iss calculated by dividing the cost of implementing the ECM by the energy cost savings (in dollars) off that ECM. Another financial indicator of the performance of a particularr ECM is the Return on Investment or ROI. The ROI is the lifetime savings (in dollars) minus the cost of the ECM, divided by the cost of the ECM. ECM s having a positive ROI s are worth pursuing. Two other financial analysis included in this report are Internal Rate of Return (IRR) and Net Present Value (NPV). Internal Rate of Return is the discount rate at which the present value of a project costs equals the present value of the project savings. Net Present Value is the difference between present value of an investment s future net cash flows and the initial investment. If the NPV equals 0, the project would equate to investing the same amount of dollars at the desiredd rate. NPV is sometimes referred to as Net Present Worth. Thesee values are provided in the summary in appendix C. Operational and maintenance measures (OMM)) are low or no cost operational opportunities, which can be implemented to have positive impacts on overall building operation, comfort levels, or energy usage. 4.1 Building Envelope The original building is built of concretee masonry units with brick veneer. The interior walls are painted block. Windows throughout the classrooms and offices in the school building are operable aluminum framed single glazing windows. The window seals are in poor condition and should be replaced to prevent outdoor air infiltration. Windows in hallways are non- operable aluminum frame single pane. The doors are aluminumm framed with single pane windows. They are in fair condition, but the seals around the doors have deteriorated with time allowing outside air to infiltrate the building and need to be replaced. The roof of the school is combination of a built up roofing system on rigid insulation with gravel surface and a rolled rubber membrane type roofing system. During the site visit it was noted that the roof was in fair condition. The built up roof system has had some reinforcement added to compensate for the addition of photovoltaic (PV) solar panels. The following energy conservation measures were identifiedd for building envelope improvements: ECM-1 Replace Window Seals New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit Page 6

11 The windows in classrooms and offices are operable aluminum frame single glazing windows. Hallway windows are non-operable aluminum frame, single glazing. The windows seem to be in fair condition, however, the seals along the window perimeters are in poor condition allowing outdoor air to infiltrate into the building. The seals around exterior windows fail over time. This leads to unwanted infiltration of unconditioned outside air and exfiltration of conditioned air resulting in increased heating energy usage. This measure calls for the replacement of all exterior window seals. Replacement of these seals will result in a reduction of the building s heating load, therefore providing natural gas savings. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM-1 Replace Window Seals Budgetary Annual Utility Savings Estimated Total Potential Payback Payback Cost Maintenance Savings ROI Incentive* (without (with Electricity Natural Gas Total Savings Incentive) Incentive) $ kw kwh Therms $ $ $ $ Years Years 24, (0.8) 0 >20 >20 * Incentive shown is per the New Jersey SmartStart Program. See section 5.0 for other incentive opportunities Expected Life: 5 years Lifetime Savings: 0 kwh 4,000 therms $4,000 This measure is not recommended due to the long payback period and negative ROI ECM-2 Replace Door Seals & Sweeps During the site visit it was observed that seals and sweeps on doors have deteriorated and are no longer useful in preventing outdoor air infiltration. Gaps between the doors and frames were noticeable and allowed for outdoor air to infiltrate the building. The calculation uses bin weather data to estimate the occupied and unoccupied bin hours. This is converted to existing energy for the occupied and unoccupied cases using the existing estimated infiltration rate and the heating temperature. The two are summed together to create the annual utility usage for the baseline. The same steps are done to calculate the proposed utility usage. The difference in heating losses through the doors results in annual heating natural gas savings.

An older Weil-McLain Series boiler rated at 2,028 MBH output and 77% efficiency operates as the lead boiler. The lag boiler is a Smith Series 28A-12 boiler rated at 2,232 MBH output and 78% efficiency. The Smith boiler was installed in Two 78.5% efficient 1.5 HP primary pumps circulate the HW through the boilers. Two 80% efficient 3 HP pumps operating in lead/lag circulate the heating HW throughout the building to provide heating to various rooms and hallways. Heating in classrooms are provided by heating only unit ventilators which are controlled by pneumatic thermostats. Hallways are heated by ceiling mounted fan coil units with thermostats located in the hallways throughout the school. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B. 4.2.b Cooling Systems The majority of the original school does not have any air conditioning systems in place. There is (1) DX split system dedicated to the guidance office with a condensing unit on the roof that provides cooling to that area. The unit has a rated cooling capacity of 9,000 btu/h and an energy efficiency ratio (EER) of There were also a number of window air conditioning units utilized in classrooms and the main office which ranged in age. These units are controlled by the teachers in those classrooms. Some of the units were quite old and could be upgraded to energy star units. It was noted during the field survey that the window units may change location in order to accommodate students with allergies. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B. New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit 8 Page

13 4.2.c Ventilation Systems Every classroom in Troy Hills Elementary School has a unit ventilator. Unit ventilators (UV) provide heating and ventilation to the classroom using hot water coils fed from the boilers. A small fan moves the air through the coil to provide heating. Modulating dampers control the amount of indoor recirculated air and outdoor air flow. The units are typically attached to an exterior wall which allows the unit to get ventilation air directly from the outdoors without using ducting. The UV s are controlled by pneumatic thermostats that regulate the heating to the user set point. There is one ceiling hung heating & ventilation (HV) unit located in the multipurpose room. This unit was controlled by a thermostat on the wall inside the multipurpose room. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B. 4.2.d Exhaust Systems As ventilation units bring outdoor air into the building, exhaust systems move indoor air into the atmosphere. During the site visit it was recorded that approximately (9) exhaust fans were located on the roof to remove air from classrooms, hallways, bathrooms, and the multipurpose room. The exhaust fans were found to be in good condition. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B. The following ECMs were identified as HVAC system improvements: ECM-3 Install Condensing Hot Water Boilers There is a Weil-McLain Boiler operating at efficiency of 77% and a Smith Boiler operating at an efficiency of 78% serving the school. Both boilers are non-condensing hot water boilers. A heating system with a 92% efficiency was proposed as a replacement. The boiler fuel consumption was calculated from the estimated system efficiency and the natural gas consumed annually per the utility bills. This was then compared to the improved efficiency of a new condensing boiler and hot water distribution system. The difference in fuel usage was the savings. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit 9 Page

See section 5.0 for other incentive opportunities Expected Life: 25 years Lifetime Savings: 0 kwh 92,500 therms $87,500 This measure is not recommended due to the high capital cost and therefore long payback period. Note: there may be insufficient ventilation levels within the building per current code requirements, but ventilation levels were not evaluated as part of the measure. If ventilation must be increased to meet codes the boiler fuel consumption may increase ECM-4 Install Premium Efficiency Pump Motors The existing heating system pumps do not have premium efficiency motors. This ECM evaluated replacing the existing standard efficiency pump motors with premium efficiency units. Savings were determined by comparing the energy usage of the existing fan motors to the energy usage with premium efficiency motors. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM-4 Install Premium Efficiency Pump Motors Budgetary Annual Utility Savings Estimated Total Potential Payback Payback Cost Maintenance Savings ROI Incentive* (without (with Electricity Natural Gas Total Savings Incentive) Incentive) $ kw kwh Therms $ $ $ $ Years Years 2, , * Incentive shown is per the New Jersey SmartStart Program. See section 5.0 for other incentive opportunities Expected Life: 20 years Lifetime Savings: 28,000 kwh 0 therms $4,000 This measure is recommended ECM-5 Replace Window A/C units with Energy Star A/C Units The elementary school is equipped with (10) window mounted AC units of varying capacity for classrooms and office spaces. These units are standard efficiency, and the New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit 10 Page

15 condition of some units ranges from fair to poor. Replacement of the existing window units with newer energy star appliances was assessed. It is assumed that the maintenance staff will install the units. It was noted during the field survey that some window mounted AC units change location between school years in order to accommodate students with allergies. The assumption of this calculation is that the operating hours and capacity stay the same. The energy savings result from operating a higher efficiency unit. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM-5 Replace Window A/C units w/energy Star Units Budgetary Annual Utility Savings Estimated Total Potential Payback Payback Cost Maintenance Savings ROI Incentive* (without (with Electricity Natural Gas Total Savings Incentive) Incentive) $ kw kwh Therms $ $ $ $ Years Years 10, (0.9) 0 >20 >20 * Does not qualify for Incentive from the New Jersey SmartStart Program. See section 5.0 for other incentive opportunities. Expected Life: 10 years Lifetime Savings: 6,000 kwh 0 therms $1,000 This measure is not recommended due to the low energy sayings and long payback period. However the additional maintenance costs associated with constantly moving the window a/c units year to year might justify the installation of more portable air conditioning units such as Move N Cool. 4.3 Control Systems The hydronic heating system includes classroom unit ventilators, HV units cabinet heaters. The boilers utilize electronic controls tied into a boiler management system (BMS), however the rest of the building is still maintained by pneumatics. The BMS allows the temperature of the hot water to be reset based on the outdoor air temperature. The pneumatic system includes valves; actuators and dampers controlled by (2) split HP air compressor motors. Thermostats are located in classrooms, hallways and the multipurpose room. The typical setpoint for the pneumatic sections is 72 o F heating, with a setback temperature of 65 o F. The HW pumps and HV unit in the multipurpose room are controlled by Hand-Off-Auto (HOA) switched. There are no ECMs associated with the controls systems.

16 4.4 Domestic Hot Water System Domestic hot water (DHW) is heated by (1) 98% efficient Bradford-White 80 gallon electric water heater rated at 4.5 kw. The DHW system is maintained at 120F and serves toilet rooms and sinks located throughout the school. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B. The following ECMs identify an improvement to the school s Domestic Hot Water System: ECM-6 Replace Domestic Hot Water Heater with Instantaneous unit This ECM assesses replacing this domestic water heater with a tankless type natural gas domestic water heater of appropriate size for the building. According to the U.S. Department of Energy, 2.5% of stored capacity is lost every hour during DHW heater standby. This value was applied to the total volume to determine annual standby losses. Proposed efficiency was based on a typical high efficiency natural gas condensing type hot water heater. The new water heater will require water and gas piping modifications, venting, and electrical connections. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM-6 Replace Domestic Hot Water Heater w/ Instantaneous unit Budgetary Annual Utility Savings Estimated Total Potentia l Payback Payback Maintenanc Incentiv Cost e Savings ROI e* (without (with Electricity Natural Gas Total Savings Incentive) Incentive) $ kw kwh Therms $ $ $ $ Years Years 10, ,400 (800) 2, , * Incentive shown is per the New Jersey SmartStart Install Program.

17 4.5 Kitchen Equipment There is no kitchen at the Troy Hills Elementary School. Food is prepared at either Parsippany High School or Brooklawn Middle School and delivered to Troy Hills each day. The food is then served to students and kept warm in electric powered warming stations. There are no ECMs associated with the controls systems. 4.6 Plumbing Systems Troy Hills Elementary School has older style fixtures in the classroom restrooms. Several of the hallway restrooms have newer, low flow fixtures. The older style plumbing fixtures consume more water than modern plumbing fixtures. There are (13) water closets in the school with an average water usage of 5.5 gallons per flush (GPF), and (11) low flow water closets with an average water usage of 1.6 GPF. There are (10) urinals in the school, with an average of 2.5 GPF and 40 faucets with an average flow rate of 3 gallons per minute (GPM). Each classroom has a sink, while only the kindergarten and first grade classrooms have restrooms. Per the number of occupants, it was estimated that each toilet and faucet is utilized approximately 4 times per day. The following ECM identifies an improvement to the school s Domestic Hot Water System: ECM-7 Water Conservation (Low Flow Fixtures) The water savings associated from replacing these fixtures with low-flow fixtures was calculated by taking the difference of the annual water usage for the proposed and base case. The basis of this calculation is the number of times each fixture is used, gallons per use, and number of fixtures. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM-7 Water Conservation (Low Flow Fixtures) Budgetary Annual Utility Savings Estimated Total Potential Payback Payback Cost Maintenance Savings ROI Incentive* (without (with Electricity Water Total Savings Incentive) Incentive) $ kw kwh Kgal $ $ $ $ Years Years 91, , ,500 (0.5) 0 >20 >20 * Does not qualify for an Incentive per the New Jersey SmartStart Program.

18 4.7 Lighting/Electrical Systems The majority of the lighting in Troy Hills Elementary School is comprised of T-8 fluorescent tube fixtures with electronic ballasts and incandescent lamps. The lighting in the Multi-Purpose room has been recently upgraded to fluorescent T5 fixtures with electronic ballasts. The bathrooms in the kindergarten classrooms have single bulb incandescent fixtures. The building s exterior lighting includes several high pressure sodium wall pack units. The pole lights in the parking lot and playground are property of Jersey Central Power and Light, and are billed monthly. A comprehensive lighting survey can be found in Appendix B. Troy Hills Elementary School utilizes 153 computers throughout the building in classrooms, offices, media centers and computer labs. All computers have flat screen LCD monitors. The following ECMs identified are improvements to Troy Hills Elementary School s lighting and electrical system: ECM-8 Lighting Replacement / Upgrades The school uses mostly T-8 fixtures with electronic ballasts in classrooms, offices, and hallway spaces. Single bulb incandescent fixtures were used in closets, storage rooms, and small bathrooms. Each switch and circuit was identified, and an inventory of fixtures, controls and locations was established during the field survey (Appendix B). There is an opportunity to reduce consumption by upgrading the incandescent fixtures to compact fluorescent lamps. This would involve a replacement of the bulb, The exterior lighting on the building walls is proposed to be changed from high pressure sodium to LED, which has a longer life and consumes much less energy. This will involve a full replacement. Energy savings for this measure were calculated by applying the existing and proposed fixture wattages to estimated times of operation. These calculations are based upon 1 to 1 replacements with the fixtures. They do not take into account lumen output and square footage. A more comprehensive study may be performed to determine correct lighting levels. Supporting calculations, including assumptions for lighting hours and annual energy usage for each fixture, are provided in Appendix C. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit 14 Page

See section 5.0 for other incentive opportunities. Expected Life: 15 years Lifetime Savings: 37,500 kwh 0 therms $ 6,000 This measure is not recommended in lieu of ECM ECM-9 Install Lighting Controls (Occupancy Sensors) Currently the light fixtures within classrooms, multipurpose room and the media center are controlled via switches regardless of occupancy. Therefore, installing an occupancy sensor in these spaces to turn off lights when the areas are unoccupied was assessed. This measure recommends installing occupancy sensors for the current lighting system. Using a process similar to that utilized in section 4.7.1, the energy savings for this measure was calculated by applying the known fixture wattages in the space to the estimated existing and proposed times of operation for each fixture. The difference between the two values resulted in an annual savings of 40,500 kwh. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM-9 Install Lighting Controls (Occupancy Sensors) Budgetary Annual Utility Savings Estimated Total Potential Payback Payback Incentive Cost Maintenance Savings ROI * (without (with Electricity Natural Gas Total Savings Incentive) Incentive) $ kw kwh Therms $ $ $ $ Years Years 4, , , , * Incentive shown is per the New Jersey Direct Install Program.

21 5.0 PROJECT INCENTIVES 5.1 Incentives Overview New Jersey Smart Start Program For this energy audit, The New Jersey Smart Start Incentives are used in the energy savings calculations, where applicable. This program is intended for medium and large energy users and provides incentives for: Electric Chillers Gas Chillers Gas Heating Unitary HVAC Ground Source Heat Pumps Variable frequency Drives/ motors Refrigeration Prescriptive and performance lighting and lighting controls The equipment is procured using a typical bid- buildd method, installed and paid for and then the incentives are reimbursed to the school. If the School District wishes to and is eligible too participate in the Energy Savings Improvement Plan (ESIP) program and/ /or the Pay for Performance Incentive Program (P4P), It cannot participate in either the Smart Startt or Direct Install Programs. Refer to appendix D for more information on the Smart Start program Direct Install Program The Direct Install Program applies to smaller facilities that have a peak electrical demand of 150 kw or less in any of the previous 122 months. Buildings must be located in New Jersey and served by one of the state s public, regulated electric utility companies. Direct Install is funded through New Jersey s Clean Energy Program and is designed to provide capital for building energy upgrade projectss to fast track implementation. The program will pay up to 70% of the costs for lighting, HVAC, motors, refrigeration, and other equipment upgrades with higher efficiency alternatives. If a building is eligible for this funding, the Direct Install Program can reducee the implementation cost of energy conservation projects. The Direct install program has specific HVAC equipment and lighting requirements and are generally applicable only to smaller package HVAC units, small boilers and lighting retrofits. The program pays a maximum amount of $75,000 per building, and up to $250,000 per customer per year. Installations must be completed by an approved Direct Install participating contractor, a list of which can be found on the New Jersey Clean Energy Website. Contractors will coordinate with the applicant to arrange installation of New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit Page 17

22 recommended measures identified in a previous energy assessment, such as this energy audit. The incentive is reimbursed to the school upon successful replacement and payment of the equipment. This school is eligible to receive funding from the Direct Install Program because the electrical demand is less than the maximum peak electrical demand of 150 kw in the last 12 month period. Refer to appendix D for more information on this program New Jersey Pay For Performance Program (P4P) The facility will be eligible for incentives from the New Jersey Office of Clean Energy. The most significant incentives are available from the New Jersey Pay for Performance (P4P) Program. The P4P program is designed for qualified energy conservation projects applied to facilities whose demand in any of the preceding 12 months exceeds 100 kw. This average minimum has been waived for buildings owned by local governments or municipalities and non-profit organizations, however. Facilities that meet this criterion must also achieve a minimum performance target of 15% energy reduction by using the EPA Portfolio Manager benchmarking tool before and after implementation of the measure(s). If the participant is a municipal electric company customer, and a customer of a regulated gas New Jersey Utility, only gas measures will be eligible under the Program. Available incentives are as follows: Incentive #1: Energy Reduction Plan This incentive is designed to offset the cost of services associated with the development of the Energy Reduction Plan (ERP). Incentive Amount: $0.10/SF Minimum incentive: $5,000 Maximum Incentive: $50,000 or 50% of Facility annual energy cost The standard incentive pays $0.10 per square foot, up to a maximum of $50,000, not to exceed 50% of facility annual energy cost, paid after approval of application. For building audits funded by the New Jersey Board of Public Utilities, which receive an initial 75% incentive toward performance of the energy audit, facilities are only eligible for an additional $0.05 per square foot, up to a maximum of $25,000, rather than the standard incentive noted above. Incentive #2: Installation of Recommended Measures This incentive is based on projected energy savings as determined in Incentive #1 (Minimum 15% savings must be achieved), and is paid upon successful installation of recommended measures. Electric Base incentive based on 15% savings: $0.09/ per projected kwh saved. For each % over 15% add: $0.005 per projected kwh saved. Maximum incentive: $0.11/ kwh per projected kwh saved Gas Base incentive based on 15% savings: $0.90/ per projected Therm saved.

Maximum incentive: $1.25 per projected Therm saved Combining incentives #2 and #3 will provide a total of $0.18/ kwh and $1.8/therm not to exceed 50% of total project cost. Additional incentives for #2 and #3 are increased by $0.005/kWh and $0.05/therm for each percentage increase above the 15% minimum target to 20%, calculated with the EPA Portfolio Manager benchmarking tool, not to exceed 50% of total project cost. Total P4P incentives are summarized below: Incentives $ Electric Gas Total Incentive #1 $0 $0 $5,000 Incentive #2 $0 $0 $0 Incentive #3 $0 $0 $0 Total $0 $0 $5,000 For the purpose of demonstrating the eligibility of the ECM s to meet the minimum savings requirement of 15% for the Pay for Performance Program, all recommended ECM s have been included in the incentive calculations resulting in a 2.8% energy savings. Based on this savings, the school would not be eligible for the Pay for Performance Program. Refer to appendix D for more information on this program Energy Savings Improvement Plan (ESIP) The Energy Savings Improvement Program (ESIP) allows government agencies to make energy related improvements to their facilities and pay for the costs using the value of energy savings that result from the improvements. Under the recently enacted Chapter 4 of the Laws of 2009 (the law), the ESIP provides all government agencies in New Jersey New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit 19 Page

24 with a flexible tool to improve and reduce energy usage with minimal expenditure of new financial resources. ESIP allows local units to use energy savings obligations to pay for the capital costs of energy improvements to their facilities. This can be done over a maximum term of 15 years. Energy savings obligations are not considered new general obligation debt of a local unit and do not count against debt limits or require voter approval. They may be issued as refunding bonds or leases. Savings generated from the installation of energy conservation measures pay the principal of and interest on the bonds; for that reason, the debt service created by the ESOs is not paid from the debt service fund, but is paid from the general fund. For local governments interested in pursuing an ESIP, the first step is to perform an energy audit. Pursuing a Local Government Energy Audit through New Jersey's Clean Energy Program is a valuable first step to the ESIP approach. The Local Finance Notice outlines how local governments can develop and implement an ESIP for their facilities. The ESIP can be prepared internally if the entity has qualified staff. If not, the ESIP must be implemented by an independent contractor and not by the energy savings company producing the Energy Reduction Plan. The ESIP approach may not be appropriate for all energy conservation and energy efficiency improvements. Local units should carefully consider all alternatives to develop an approach that best meets their needs. Refer to appendix D for more information on this program.

25 6.0 ALTERNATIVE ENERGY SCREENING EVALUATION Solar Photovoltaic Rooftop Solar Power Generation The facility was evaluated for the potential to install rooftop photovoltaic (PV) solar panels for power generation. Present technologyy incorporates the use of solar cell arrays that produce direct current (DC) electricity. This DC current is converted to alternating current (AC) with the use of an electrical device known as an inverter. The building s roof has sufficient room to install a solar cell array. However, there is not sufficient room to accommodate a system that will provide the entire electrical demand of the building. For this analysis we will consider a 30.0 KW system. An existing PV system takes up a large section of the existing roof space. The PVWATTS solar power generation model was utilized generation; this model is provided in Appendix E. to calculate PV power Installation of (PV) arrays in the state New Jersey will allow the owner to participate in the New Jersey solar renewable energy certificates program (SREC). This is a program that has been set up to allow entities with large amounts of environmentally unfriendly emissions to purchase credits from zero emission (PV) solar-producers. An alternative compliance penalty (ACP) is paid for by the high emission producers and is set each year on a declining scale of 3% per year. One SREC credit is equivalent to 1000 kilowatt hours of PV electrical production; these credits can be traded for period of 15 years from the date of installation. Payments that will be received by the PV producer (school) will change from year to year dependent upon supply and demand. There is no definitive way to calculate an exact price that will be received by the PV producer for SREC credits over the next 15 years. Renewablee Energy Consultants estimates an average of $82/ SREC for 2012 and this number was utilized in the cash flow for this report. The system costs for PV installations were derived from recent solar contractor budgetary pricing in the state of New Jersey and include the total cost of the system installation (PV panels, inverters, wiring, ballast, controls). The cost of installation is currently about $4.00 per watt or $4,000 per kw of installed system, for a typical 100 kw system. There are other considerations that have not been included in this pricing, such as the condition of the roof and need for structural reinforcement. Photovoltaic systems can be ground mounted if the roof is not suitable, however this installation requires a substantial amount of open property (not wooded) and underground wiring, which adds more cost. PV panels have an approximate 20 year life span; however, the inverte device that converts DC electricity to AC has a life span of 10 to 12 years and will most likely need to be replaced during the useful life of thee PV system. The implementat tion cost including replacing the current roof membrane which is out of warranty and savings related to this ECM are presented in Appendix E and summarized as follows: New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit Page 21

It is suggested, however, that the school continue to monitor the SREC credits and evaluate the PV installation again should the SREC credit values increase. It is also important to note that a feasibility study should be performed by a third party solar contractor, before any installation takes place Solar Thermal Hot Water Generation Active solar thermal systems use solar collectors to gather the sun s energy to heat water, another fluid, or air. An absorber in the collector converts the sun s energy into heat. The heat is then transferred by circulating water, antifreeze, or sometimes air to another location for immediate use or storage for later utilization. Applications for active solar thermal energy include providing hot water, heating swimming pools, space heating, and preheating air in residential and commercial buildings. A standard solar hot water system is typically composed of solar collectors, heat storage vessel, piping, circulators, and controls. Systems are typically integrated to work alongside a conventional heating system that provides heat when solar resources are not sufficient. The solar collectors are usually placed on the roof of the building, oriented south, and tilted around the site s latitude, to maximize the amount of radiation collected on a yearly basis. Several options exist for using active solar thermal systems for space heating. The most common method involves using glazed collectors to heat a liquid held in a storage tank (similar to an active solar hot water system). The most practical system would transfer the heat from the panels to thermal storage tanks and transfer solar produced thermal energy to use for domestic hot water production. DHW is presently produced by gasfired water heaters and, therefore, this measure would offer natural gas utility savings. 6.2 Demand Response Curtailment Presently, Electricity is delivered by JCP&L, which receives the electricity from regional power grid RFC. PMJ is the regional transmission organization (RTO) that coordinates the movement of wholesale electricity in all or parts of 13 states and the District of Columbia including the State of New Jersey. New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit 22 Page

27 Utility Curtailment is an agreement with the utility provider s regional transmission organization and an approved Curtailment Service Provider (CSP) to shed electrical load by either turning major equipment off or energizing all or part of a facility utilizing an emergency generator; therefore, reducing the electrical demand on the utility grid. This program is to benefit the utility company during high demand periods and utility provider offers incentives to the CSP to participate in this program. Enrolling in the program will require program participants to drop electrical load or turn on emergency generators during high electrical demand conditions or during emergencies. Part of the program also will require that program participants reduce their required load or run emergency generators with notice to test the system. A pre-approved CSP will require a minimum of 100 kw of load reduction to participate in any curtailment program. From November 2011 through October 2012 the facility had a peak electricity demand of 68.0 kw and a minimum of 40.8 kw. The monthly average over the observed 12 month period was 51.1 kw. This measure is not recommended because the school will be unable to meet the minimum electrical load reduction of 100 kw.

28 7.0 EPA PORTFOLIO MANAGER The EPA Portfolio Manager benchmarkin ng tool was used to assess the building s energy performance. Portfolio Manager provides a site andd source Energy Use Intensity (EUI), as well as an Energy Star performance rating for qualifying building types. The EUIs are provided in kbtu/ /ft 2 /year, and the performance rating represents how energy efficient a building is on a scale of 1 to 100, with 100 beingg the most efficient. In order for a building to receive and Energy Star label, the energy benchmark rating must be at least 75. As energy use decreases from implementation of the proposed measures, the Energy Star rating will increase. The site EUI is the amount of heat and electricity consumed by a building as reflected in utility bills. Site energy may be deliveredd to a facilityy in the form of primary energy, which is raw fuel burned to create heat or electricity, such as natural gas or oil; or as secondary energy, which is the product created from a raw fuel such as electricity or district steam. To provide an equitable comparison for different buildings with varying proportions of primary and secondary energy consumption, Portfolio Manager uses the convention of source EUIs. The source energy also accountss for lossess incurred in production, storage, transmission, and delivery of energy to the site, which provide an equivalent measure for various types of buildings with differingg energy sources. The results of the Portfolio Manager benchmarking tool are contained in the table below. Building Troy Hills Elementary School Site EUI kbtu/ft /yr Source EUI Btu/ft /yr Energy Star Rating (1-100) 55 The Troy Hills Elementary School has a below average site EUI and therefore an above average Energy Star Rating Score of 555 (50 being the median score). By implementing the measures discussed in this report, it is expected that the EUI can be reduced and the Energy Star Rating increased. The Portfolio Manager account can be accessed by entering the username and password shown below at the login screen of the Portfolio Manager website ( Username: parsippanyboe Password: energystar A full EPA Energy Star Portfolio Manager Report is located in Appendix G.
