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 Lake Parsippany Elementary School Address 225 Kingston Road Parsippany, NJ Square Feet 36,747 Construction Date Original:1949 Additions: 1956, 1961 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 $8,400 may be realized with an average simple payback period of 4.4 years.

8 3.0 UTILITY Utilities include electricity and natural gas. Electricity is delivered and supplied by Central Power and Lighting (JCP&L). Natural gas is deliveredd by New Jersey Natural Gas. 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 Annual Usage Annual Cost Blended Rate Supply Rate Demand Rate Peak Demand Min. Demand Avg.

Natural gas consumption was highestt in winter months for heating. See Appendix A for a detailed utility analysis. New Jersey BPU Parsippany-T Troy Hills Board of Education- Energy Audit Page 4

9 Total Annual Energy Usage (kbtu) Natural Gas 82% Electric 18% Figure 2: Annual Site Energy Usage Naturall Gas 60% Total Annual Energy Cost Electric 40% Figure 3: Annual Energy Cost Under New Jersey s energy deregulation law, thee supply portion of the electric (or natural gas) bill is separated from the delivery portion. 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.

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 that it takes to break even referred to as Simple Payback. Simple payback is 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 savingss (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 a mixture of painted block in the old wing and painted plaster is some parts of the new wing. Many windows throughout the school in classroomss and offices are operable aluminumm framed double glazed windows. Windows in hallways are non-operable aluminum frame double pane. The windows seem to be in fair condition. The doors in the original section were wood framed doors that appeared to be in fair condition. Exterior doors in the hallways and lobby were aluminum frame and were in good condition. The roof of the original section of the building is asphalt and in fair condition. The roof of the new sections was a multi-ply built up roofingg system with a gravel surface. It appeared to be in good condition at the time of the visit. Theree are no ECMs associated with the Building Envelope. New Jersey BPU Parsippany-T Troy Hills Board of Education- Energy Audit Page 6

11 4.2 ECM-1 Door Replacement in 1941 Section The classroom hallway in the 1941 section has a set of wood doors on the building exterior. The doors are in are original to the building and in fair condition. To calculate the savings, the heat losses through the door assembly using were found using the existing U-value of 0.64 for a wood door, and bin weather data for nearby Newark, NJ. The values were totaled to determine the existing annual energy losses. Heating and cooling energy loss values were determined by using a thermal resistance with a new u-value for an aluminum door. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM-1 Door Replacement in 1941 Section 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 * Incentive shown is per the New Jersey SmartStart Program. See section 5.0 for other incentive opportunities Expected Life: 25 years Lifetime Savings: 0 kwh 500 therms $ 800 This measure is not recommended due to the high capital cost and long payback. 4.3 ECM-2 Replace Roof in 1941 Section The roof is constructed of metal roof decking, insulation, and a rubber mat system. The roof has surpassed its useful life and needs to be replaced. This ECM addresses replacing the roof to minimize heating and cooling energy losses. To calculate the savings, the heat losses through the roof assembly of the school was found using the existing roof s R-value of 19.0 and bin weather data for nearby Newark, NJ. The values were totaled to determine the existing annual energy losses. Heating and cooling energy loss values were then determined with a thermal resistance which included the replacement roof R-value of The annual energy savings of replacing the roof is detailed in the summary table below. 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 7 Page

See section 5.0 for other incentive opportunities Expected Life: 30 years Lifetime Savings: 0 kwh 6,000 therms $9,000 This measure is not recommended due to the high capital cost and long payback. However the useful lifetime of this roof has long past and replacement should be considered. 4.4 HVAC Systems 4.2.a Heating Systems The school had (2) boiler rooms. The main boiler room contains (2) Smith 28A-12 3,000 MBH steam boilers rated at 78% efficiency. A portion of this steam is used to heat hot water through the use of a shell and tube heat exchanger. It is estimated that about 44% of the school is heated by hot water. The boiler room in the original construction of the building contains a Weil-McLain 588 Series rated at 60% efficiency with 813 MBH steam output. The steam systems are maintained at 10 psi in the main boiler room and 8psi in the original construction. Steam condensate is returned to a condensate return tank which is mixed with makeup water and pumped back to the boilers. Heating hot water is circulated throughout the building via (2) 84% efficient 1.5 hp pumps. Heating in classrooms are provided by heating only unit ventilators which are controlled by pneumatic thermostats in the two new wings while controls in the original wing have been updated to electronic controls. Hallways are heated by a combination of fan coil units and perimeter fin tube radiators with thermostats located in the hallways throughout the school. The multi-purpose room is heated by (2) ceiling hung heating & ventilation (HV) units that utilize hot water coils. There are additionally (2) ceiling hung unit heaters that heat a few spaces in 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 school does not have any air conditioning systems in place. New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit 8 Page

13 There were a few window air conditioning units utilized in a number of places 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. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B. 4.2.c Ventilation Systems Every classroom in Lake Parsippany Elementary School has a unit ventilator. Unit ventilators (UV) are assemblies, typically attached to a wall with a window, which allows the unit to ventilate the space with outdoor air. According to the State of New Jersey, classrooms have to be ventilated in accordance with ASHRAE Standard and Standard to provide an acceptable indoor air quality for the students and school staff. Located within the unit ventilators are fans that force a mixture of ambient air and outdoor air over hot water coils to heat and ventilate the space in winter months. Most classrooms had UVs controlled by pneumatic, however some classrooms in the original wing had UVs that were digitally controlled. Hallways are ventilated similarly with ceiling mounted fan coil units. There were also two ceiling hung heating & ventilation (HV) units located in the multipurpose room. These units were controlled by a pneumatic 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. The amount of indoor air exhaust is in general less than the amount of outdoor air introduced into the building. This allows the building to be positively pressurized. A number of exhaust fans are 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. The exhaust fans in the 1944 construction were original to the building and were no longer 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 (1) Condensing Hot Water Boiler New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit 9 Page

14 There are two (2) A.O. Smith steam boilers operating at efficiencies of 78%. A portion of the steam is converted to hot water through the use of a shell and tube heat exchanger and used to heat approximately 44% of the building. For this calculation it was assumed that the heat exchanger will decreased the efficiency of the steam system by approximated 15% because of losses associated with the conversion from steam to hot water. A condensing hot water heating system with an average efficiency of 92% was proposed as a replacement for the hot water portion of the building only. While onsite it was observed that there is ample room in the existing boiler room to install a condensing hot water boiler. The existing shell and tube heat exchanger should remain in place to act as a backup to the system. Note: In order to properly size a condensing hot water boiler for the school an engineering rule of thumb of 40 btu/h per square foot of heater space was used. The same calculation was done for the existing boilers which resulted in almost 80 btu/h per ft 2. This means that the existing boilers might be grossly oversized for this building type which may dramatically reduce the heating system efficiency due to short cycling. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM-3 Install (1) Condensing Hot Water Boiler 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 134, ,600 5, , ,800 >20 >20 * Incentive shown is per the New Jersey SmartStart Program. See section 5.0 for other incentive opportunities Expected Life: 25 years Lifetime Savings: 0 kwh 115,000 therms $142,500 This measure is not recommended. Note: According to school personnel, this boiler room is prone to flooding. If this measure is pursued in the future to replace the existing boilers it should be place on a higher slab to prevent water damage due to flood waters. This will increase ECM costs ECM-4 Install Premium Efficiency Motors on Hot water Pumps The hot water system consists of two (2) 1/2 HP pumps serving the school. The pumps are constant volume with standard efficiency motors. The pumps operate in lead/lag formation cycling on and off during the entire heating season which contributes to the buildings electrical usage. By installing equivalently sized premium efficiency motors, the electricity usage can be dramatically reduced. New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit 10 Page

See section 5.0 for other incentive opportunities Expected Life: 18 years Lifetime Savings: 12,600 kwh 0 therms $ 1,800 This measure is not recommended. Note: According to school personnel, this boiler room is prone to flooding. If this measure is pursued in the future to replace the existing boilers it should be place on a higher slab to prevent water damage due to flood waters. This will increase ECM costs. 4.5 Control Systems The school had a Magnum Boiler Management System in place; however the controls cannot be accessed or changed by the school district. The district HVAC specialist indicated that the steam pressure reset based on outdoor air temperature was not enabled in the controls or not working properly. The heating system includes classroom unit ventilators, HV units, fan coil units and perimeter fin tube radiators. The new wing utilizes Trane electronic controls which were installed around the same time the boiler was added. The HVAC specialist mentioned that the Trane thermostats did not work very well. The newer wings are controlled through pneumatics with one wing heated by hot water and the other by steam. The pneumatic system includes valves, actuators and dampers controlled by (2) Marathon Electric split horsepower air compressor motors. Thermostats are located in classrooms, hallways and the multipurpose room. The typical heating set point for the pneumatic section is 72F heating with no setback controls. The old wing has digital controls set to 68F for heating and cooling but teachers can manually change the temperature whenever they want. There are setback controls in the old wing. The following ECMs identified are improvements to the school s HVAC control system: ECM-5 Replace Thermostats w/ Programmable T-stats and Enable Setback The heating system at Lake Parsippany Elementary School is programmed to maintain an indoor temperature of 72 o F during all hours. Energy savings could be recognized New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit 11 Page

16 with the implementation of setback controls to maintain a minimum temperature during unoccupied hours. The setback temperature considered in this calculation was 65 o F. The annual natural gas usage for the facility was taking from the utility bills. According to the US Energy Information Agency (EIA), implementing a night setback system typically saves 5% of a facility s annual heating cost. This savings is multiplied by the annual natural gas and converted to monetary savings using the unit cost of the fuel obtained from the utility analysis. Savings are seen from temperature scheduling for occupied and unoccupied hours. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM-5 Replace Thermostats w/ Programmable T-stats and Enable Setback Budgetary Estimated Total Payback Payback Annual Utility Savings Incentive Cost Maintenance Savings ROI * (without (with Electric Electric Nat Gas Total Savings incentive) incentive) $ kwh kw Therms $ $ $ $ Years Years 14, ,900 2, , * There is no incentive available through the New Jersey Smart Start Programs for this ECM. See section 5.0 for other incentive opportunities. Expected Life: 15 years Lifetime Savings: 0 kwh 28,500 therms $ 36,000 This measure is recommended ECM-6 Install Steam Pressure Reset Controller The elementary school currently houses two steam located in one boiler room. The boilers produce constant 8 psi low pressure steam regardless of the outdoor temperature conditions during the heating months in order to heat the facility. This ECM evaluates the installation of a steam pressure reset controller if the addition of condensing hot water boilers is not pursued. The purpose of the steam pressure reset is to modulate the steam pressure depending on the outdoor air temperature; meaning on a warmer day outside, the boiler can stand to produce lower pressure steam to meet facility heating demands. Savings were determined through improved boiler efficiency as the steam decreased. The calculation was performed by establishing a baseline by using 8 psi as the current low pressure setpoint at 233F, assuming saturated steam and comparing it to the proposed case. The proposed case assumed that they pressure could be dropped as low as 2 psi on some days during the shoulder months, therefore an average of 5 psi at 227F was used. The reduction in combustion and radiant losses produced the fuel savings. New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit 12 Page

See section 5.0 for other incentive opportunities. Expected Life: 15 years Lifetime Savings: 0 kwh 6,000 therms $ 7,500 This measure is not recommended. 4.6 Domestic Hot Water System There were two domestic hot water (DHW) heaters located in the school. One 40,000 btu/h natural gas unit had a 40 gallon capacity and was located in the main boiler. The second DHW heater was an 80 gallon electric unit with a maximum of electricity input of 4.5 kw. In general the DHW system maintained the water at about 120F. The DHW system serves the 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 identifies an improvement to the school s Domestic Hot Water System: ECM-7 Replace Electric Domestic Hot Water Heater with a Condensing Natural Gas Unit The school utilizes a 50 gallon Bradford White natural gas fired domestic hot water heater and an 80 gallon Rheem electric hot water heater. This ECM assesses replacing the electric domestic water heater with a more efficient tankless type domestic water heater sized to meet the domestic hot water requirements of 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. New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit 13 Page

See section 5.0 for other incentive opportunities. Expected Life: 20 years Lifetime Savings: 258,000 kwh (8,000) therms $ 30,000 This measure is recommended. 4.7 Kitchen Equipment There is no kitchen at the Lake Parsippany Elementary School. Food is prepared at either Parsippany High School or Brooklawn Middle School and delivered to Lake Parsippany each day. The food is then served to students and kept warm in electric powered warming stations. There are no ECMs associated with the kitchen equipment. 4.8 Plumbing Systems Lake Parsippany Elementary School has older style fixtures in the hallway and classroom restrooms. The older style plumbing fixtures consume more water than modern plumbing fixtures. There are (32) water closets in the school with a rate of 5.5 gallons per flush (GPF). There are (5) urinals in the school, with an average of 3.0 GPF and 41 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-8 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 New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit 14 Page

Expected Life: 30 years Lifetime Savings: 0 kwh 3,000 kgal $ 39,000 This measure is not recommended. 4.9 Lighting/Electrical Systems The majority of the lighting in Lake Parsippany 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. A comprehensive lighting survey can be found in Appendix B. Lake Parsippany Elementary School utilizes 192 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 Robert Erskine Elementary School s lighting and electrical system: ECM-9 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 New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit 15 Page

20 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.

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 4.6.1, 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.

22 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-T Troy Hills Board of Education- Energy Audit Page 18

23 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. New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit 19 Page

24 For each % over 15% add: $0.05 per projected Therm saved. Maximum incentive: $1.25 per projected Therm saved Incentive cap: 25% of total project cost Incentive #3: Post-Construction Benchmarking Report This incentive is paid after acceptance of a report proving energy savings over one year utilizing the Environmental Protection Agency (EPA) Portfolio Manager benchmarking tool. 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. For each % over 15% add: $0.05 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, recommended ECM s have been included in the incentive calculations resulting in a 6.8% 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 New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit 20 Page

25 of the Laws of 2009 (the law), the ESIP provides all government agencies in New Jersey 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.

26 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 KW system. 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 and savings related to thiss ECM are presented in Appendix E and summarized as follows: New Jersey BPU Parsippany-T Troy Hills Board of Education- Energy Audit Page 22

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 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. 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 New Jersey BPU Parsippany-Troy Hills Board of Education- Energy Audit 23 Page

28 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 73.9 kw and a minimum of 64.2 kw. The monthly average over the observed 12 month period was 69.8 kw. This building currently has a 125 kw natural gas generator on site. The district currently has a contract with Ener-Noc for a few of their school buildings. As of January 2013 their contract has been renewed with Ener-Noc. It is not recommended that they adjust their current contract at this time.

29 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 Lake Parsippany Elementary School Site EUI kbtu/ft /yr Source EUI Btu/ft /yr Energy Star Rating (1-100) 20 The Lake Parsippany Elementary School has a below average site EUI and therefore a below average Energy Star Rating Score of 20 (50 being the median score). This is most likely attributed to the poor building envelope and antiquated boilers. 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.
