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 Springfield 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 James Caldwell Elementary School Address 36 Caldwell Place, Springfield, NJ Square Feet Construction Date 39, 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, there are no interactive effects calculated. There are three 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 6.0. Each measure recommended by CHA typically has a simple payback period of 15 years or less to be consistent with the requirements of the 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 $4,650 may be realized with an average simple payback period of 11.9 years.

7 2.0 INTRODUCTION AND BACKGROUND The James Caldwell Elementary School is a 39,300 square foot building consisting of three floors. The building was constructed in 1901 with additions in 1925 and The school includes the following spaces: classrooms, offices, multipurpose room, storage, toilet rooms and a media center. The school hours of operation are from 8:40 AM 3:00 PM Monday through Friday, with various after-school activities and Saturdays. The school has approximately 255 students and 31 faculty and staff members. The school is a 1 to 1 policy which implies that each student has their own laptop. The total number of computers is approximately 260 computers. Figure 1: James Caldwell Elementary School New Jersey BPU Springfield Board of Education- Energy Audit 3 P age

8 3.0 UTILITY Utilities include electricity and natural gas. Electricity is delivered by JCP&L (Jersey Central Power & Lights) and is currently supplied by South Jersey Energy. Natural gas is delivered and supplied by Public Service Enterprise Group (PSE&G). The school district is charged for water/ sewer which is provided by New Jersey American Water. For the 12-month period ending in April 2012, the utilities usage for the building was as follows: Table 2: Actual Cost & Site Utility Usage Electric Annual Usage 142,120 kwh/year Annual Cost 22,478 $ Blended Rate $/kwh Supply Rate $/kwh Demand Rate 4.88 $/kw Peak Demand 73.7 kw Min. Demand 40.0 kw Avg. Demand 58.0 kw Natural Gas Annual Usage 18,113 Therms/year Annual Cost 17,998 $ Rate $/Therm Water Annual Usage 496 Kgal/year Annual Cost 3, $ Rate 7.78 $/Kgal Electrical usage was generally higher in the summer months when air conditioning equipment is operational. Natural gas consumption was highest in winter months for heating. See Appendix A for a detailed utility analysis. New Jersey BPU Springfield Board of Education- Energy Audit 4 P age

The supply portion is open to competition, and customers can shop around for the 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: 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 4.1 Building Envelope The building is built of concrete masonry units with brick veneer. The interior walls are block walls with painted plaster. There is currently no insulation in the walls of the school. Windows throughout the school building are operable aluminum framed double pane glazing windows. The windows seem to be in fair condition. During the kickoff meeting it was noted that the windows were replaced within the last decade and there were no issues with infiltration. The doors were in fair condition as well. The seals around the doors were intact. The roof of the school is a four ply built up roofing system on rigid insulation. During the site visit it was noted that the roof was in fair condition. 4.2 HVAC Systems 4.2.a Heating Systems James Caldwell Elementary School has two steam boilers. One (1) Parker boiler was installed in 1997 and has a 2,100 MBH input. The other boiler is an H.B. Smith Boiler with an input of 1,310 MBH. The boilers operate in a lead / lag fashion and the control system is programmed to alternate the lead and lag boilers. The boilers operate at 5 PSI of pressure during the day and 3 PSI at night. The boilers are required to operate during the months of October through April. The boilers are completely shut down the remaining months. The classrooms are heated and ventilated by steam unit ventilators. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B. 4.2.b Cooling Systems Cooling is provided to the classroom spaces through two (2) one-ton window air conditioning units. These units are controlled by the staff. There is no cooling in the auditorium / gymnasium. The Main Office, Principal Office and Nurse Office are served by a fan coil unit ducted to diffusers in the space. The system has a 5-ton remote condenser outside. This unit was installed in The Media Center has two (2) unit ventilators that are retrofitted with DX cooling coils connected to (2) remote condensing units. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B. 4.2.c Ventilation Systems The Auditorium / Gymnasium is heated and ventilated using two (2) 4,500 CFM HV Units. New Jersey BPU Springfield Board of Education- Energy Audit 6 P age

11 Ventilation is supplied to the classrooms through the unit ventilators. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B. 4.2.d Exhaust Systems The school utilizes exhaust fans of various sizes located on the roof to exhaust restrooms and storage areas. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B. 4.3 Control Systems The window units are controlled manually. The unit ventilators are controlled by a Siemens System 600 pneumatic control system. A Honeywell air compressor is used to provide compressed air for this pneumatic control system. The boilers have their own electrical control system by Honeywell. During the heating season, the temperature is set at 68 o F during occupied hours and 50 o F during unoccupied hours. During the cooling season, the temperature is set at 70 o F during occupied hours and 85 o F during unoccupied hours. The Unit Ventilators and Heating and Ventilation Units are controlled by pneumatic valves, dampers and actuators. The pneumatic controls are not precise due to the age of the system. 4.4 Domestic Hot Water System The school has (1) Rheem gas fired domestic hot water heater located in the mechanical room. The capacity is of 50 gallons with an input of 38,000 BTU. This unit is in good condition and installed in There is also (1) electric 4,500 W domestic water heater serving the building as well. The capacity of this water heater is 65 gallons. This water heater is in good condition. This water heater is under the stairs and natural gas is not present in this wing and venting is an issue. The domestic hot water heaters serves the toilet rooms and sinks located throughout the school. The 1-1/2 piping for this system has 15 feet of exposed pipe that is routed through an unconditioned space in the mechanical room. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B. 4.5 Kitchen Equipment The kitchen is for warming food only. All the cooking is done in the high school. There aren t any walk-in coolers / freezers, kitchen hoods, or a booster heater serving a dishwasher.

12 4.6 Plumbing Systems The plumbing fixtures varied in age with the age of the additions. Generally fixtures installed before the 90s consume more water than modern plumbing fixtures. On average these urinals consume approximately 3 gallons per flush (gpf) and toilets typically use 3.5 gpf. During the site visit the number of toilets and urinals were documented to be replaced with low flow fixtures. Low flow toilets and urinals use 1.28 gpf and 1.0 gpf respectfully. 4.7 Lighting/Electrical Systems The majority of the lighting in the elementary school is compact florescent lighting (CFLs) with electronic ballasts, twin biaxial fluorescent lamps and incandescent lamps. The school utilizes 34 watt T-8 fluorescent tube fixtures for offices, Auditorium / Gymnasium (multipurpose room), hallways, and classrooms and 100 W incandescent bulbs for storage closets and restrooms. Some spaces in the newest addition uses twin biaxial fluorescent lamps in the restrooms, hallway, and the media center. Lights are switched on manually. The building exterior utilizes a combination of MV175 and 400W metal halide wall packs that are controlled by a timer. 5.0 ENERGY CONSERVATION MEASURES Energy conservation measures (ECM s) are energy savings 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=100,000 BTU), propane gas (Gallons=91,650 BTU), Fuel Oil (Gallons =138,700 Btu) and water (KGAL=1000 gallons). These recommendations are influenced by the time 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) of that ECM. Another financial indicator of the performance of a particular ECM is the Return on Investment or ROI. Two other financial analyses 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 desired rate. NPV is sometimes referred to as Net Present Worth. These values are provided in the summary in appendix C. 5.1 Building Envelope There are no ECMs associated with the Building Envelope. New Jersey BPU Springfield Board of Education- Energy Audit 8 P age

13 5.2 HVAC Systems The following ECM is associated with the HVAC Systems: ECM-1 Replace Window A/C Units w/ductless Splits The school has uses (1) ton window air conditioning units to cool classrooms on hot days. The total of these units is 17. These units are traditional efficiency (EER Value of 11.0) units and the condition of the units is fair to good. This ECM assesses replacing these window units with DX cooling split systems and integration into the BAS. The assumption of this calculation is that the operating hours and capacity remain the same. The energy savings is the result of operating a higher efficiency unit. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM-1 Replace Window A/C Units w/ Ductless Splits Budgetary Estimated Total Potential Payback Payback Annual Utility Savings Incentive Cost Maintenance Savings ROI * (without (with Electricity Natural Gas Total Savings Incentive) Incentive) $ kw kwh Therms $ $ $ $ Years Years 8, (0.9) 200 >20 >20 * Incentive shown is per the New Jersey SmartStart Program. See section 5.0 for other incentive opportunities Expected Life: 15 years Lifetime Savings: 3,000 kwh 0 therms $ 500 This measure is not recommended. 5.3 Control Systems The following ECM is associated with the Controls Systems: ECM-2 Demand Controlled Ventilation (Auditorium / Gymnasium) The Auditorium / Gymnasium (Multi-purpose room) are heated by (2) Nesbitt heating & ventilation (HV) units. These units are designed to provide ventilation based on maximum occupancy. This occurs infrequently and reducing the amount of ventilation will result in energy savings. Installation of carbon dioxide (CO2) sensors will allow for a reduction of outside air during periods of low occupancy. The quantity of ventilation air will be based on maintaining an acceptable CO 2 level in the space as an indicator of indoor air quality. A limit of 1000 PPM of CO 2 is recommended in ASHRAE Standard , Ventilation for Acceptable Indoor Air Quality. Sensors will be installed to measure the building air CO 2 concentration, and the control sequence of operation changed. During unoccupied periods, the outside air dampers should be closed.

14 Bin weather data was utilized to obtain the annual operating hours required to maintain the current setpoint of 70 F. The BTU/Hr rating is calculated from the OA conditions and CFM. It is assumed that installing the controls will reduce the amount of OA to be conditioned by 20%. The annual thermal usage was estimated. The energy saving is the difference in natural gas usage. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM-2 DCV Controls (Gymnasium & Cafeteria) Budgetary Estimated Total Potential Payback Payback Annual Utility Savings Incentive Cost Maintenance Savings ROI * (without (with Electricity Natural Gas Total Savings Incentive) Incentive) $ kw kwh Therms $ $ $ $ Years Years 17, (0.2) * Incentive shown is per the New Jersey SmartStart Program. See section 5.0 for other incentive opportunities Expected Life: 15 years Lifetime Savings: - kwh 13,500 therms $ 13,500 This measure is not recommended. 5.4 Domestic Hot Water System The following ECM is associated with the Domestic Hot Water Systems: ECM-3 Insulate DHW Piping Insulation The 1-1/2 piping for the DHW system has 15 feet of exposed pipe routed through an unconditioned space in the mechanical room. The exposed piping loses heat to the ambient air and the efficiency of the heating system decreases. To minimize the heat transfer between the pipes and ambient air, the exposed piping should be insulated with fiberglass pipe insulation. To compute the amount of heat lost through the uninsulated hot water piping, the exposed surface area of the piping was determined. Transmission coefficients for copper piping were then utilized in conjunction with the ambient air and hot water temperatures to generate correction factors for the heat transfer calculation. By installing 1 polyethylene insulation on the hot water piping, it is expected this ECM will reduce annual natural gas usage. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: New Jersey BPU Springfield Board of Education- Energy Audit 10 P age

See section 5.0 for other incentive opportunities Expected Life: 25 years Lifetime Savings: - kwh 1,300 therms $ 1,300 This measure is recommended. 5.5 Kitchen Equipment There are no ECMs associated with the Kitchen Equipment. 5.6 Plumbing Systems The following ECM is associated with the Plumbing Systems: ECM-4 Install Low Flow Plumbing Fixtures The school has a mixture of older and newer fixtures in the restrooms. The older fixtures consume more water than modern plumbing fixtures. It was determined that there are 5 urinals and 15 toilets that have an average water usage of 3.0 gpf, 3.5 gpf respectfully. Per the number of occupants, it was estimated that each toilet and urinal is utilized approximately nine times per day. 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 J and summarized as follows: New Jersey BPU Springfield Board of Education- Energy Audit 11 P age

See section 5.0 for other incentive opportunities. Expected Life: 15 years Lifetime Savings: - kwh 1,500 kgals $ 15,000 This measure is not recommended. 5.7 Lighting/Electrical Systems The following are ECMs associated with the Lighting/Electrical Systems: ECM-5 Lighting Replacement / Upgrades The majority of the lighting in the elementary school is compact florescent lighting (CFLs) with electronic ballasts, twin biaxial fluorescent lamps and incandescent lamps. The school utilizes 34 watt T-8 fluorescent tube fixtures for offices, Auditorium / Gymnasium (multipurpose room), hallways, and classrooms and 100 W incandescent bulbs for storage closets and restrooms. Some spaces in the newest addition uses twin biaxial fluorescent lamps in the restrooms, hallway, and the media center. Lights are switched on manually. The building exterior utilizes a combination of MV175 and 400W metal halide wall packs that are controlled by a timer. 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: ECM-5 Lighting Replacement / Upgrades Budgetary Estimated Total Potential Payback Payback Annual Utility Savings Incentive Cost Maintenance Savings ROI * (without (with Electricity Natural Gas Total Savings Incentive) Incentive) $ kw kwh Therms $ $ $ $ Years Years 49, ,000-3, , , * Incentive shown is per the New Jersey SmartStart Install Program.

17 Expected Life: 15 years Lifetime Savings: 270,000 0 therms $ 48,000 This measure is not recommended in lieu of ECM ECM-6 Install Lighting Controls (Occupancy Sensors) Lighting in the spaces is controlled manually by light switches with the exception of the gymnasiums. In the gymnasiums there are fixture mounted motion sensors that power off the lights if no one is occupying the gyms. Review of the comprehensive lighting survey determined that lighting in classrooms and various other spaces are typically operational, 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 implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM-6 Install Lighting Controls (Occupancy Sensors) Budgetary Estimated Total Potential Payback Payback Annual Utility Savings Incentive Cost Maintenance Savings ROI * (without (with Electricity Natural Gas Total Savings Incentive) Incentive) $ kw kwh Therms $ $ $ $ Years Years 12,000-11,000-1, , , * Incentive shown is per the New Jersey SmartStart Install Program. See section 5.0 for other incentive opportunities. Expected Life: 15 years Lifetime Savings: 165,000 kwh 0 therms $ 25,500 This measure is not recommended in lieu of ECM ECM-7 Lighting Replacements with Controls (Occupancy Sensors) This measure is a combination of ECM-5 and ECM-6; recommending replace/upgrade the current lighting fixtures to more efficient ones and installing occupancy sensors on the new lights. Interactive effects of the higher efficiency lights and occupancy sensors lead the energy and cost savings for this measure to not be cumulative or equivalent to the sum of replacing the lighting fixtures alone and installing occupancy sensors without the lighting upgrade. The costs of the lighting are majority from lighting vendors quotations and the costs of the occupancy sensors are from R.S Means.

19 6.0 PROJECT INCENTIVES 6.1 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- build method, installed and paid for and then the incentives are reimbursed to the school. If the School District wishes to and is eligible to 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 Start 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 12 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 projects 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 reduce 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 recommended measures identified in a previous energy assessment, such as this New Jersey BPU Springfield Board of Education- Energy Audit 15 P age

20 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 school 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 School annual energy cost The standard incentive pays $0.10 per square foot, up to a maximum of $50,000, not to exceed 50% of school 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. 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 New Jersey BPU Springfield Board of Education- Energy Audit 16 P age

21 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, all ECM s (both recommended and not recommend) have been included in the incentive calculations. Based on this, the James Caldwell Elementary school building would be eligible for incentive #1 and not eligible for incentives #2 and #3. 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 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 New Jersey BPU Springfield Board of Education- Energy Audit 17 P age

22 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.

23 7.0 ALTERNATIVE ENERGY SCREENING EVALUATION 7.1 Solar Photovoltaic Rooftop Solar Power Generation The school was evaluated for the potential to install rooftop photovoltaic (PV) solar panels for power generation. Present technology 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 50.0 KW system. The PVWATTS solar power generation model was utilized to calculate PV power generation; this model is provided in Appendix E. 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. Renewable Energy Consultants estimates an average of $125/ SREC for 2013 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 50.0 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 inverter 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 the PV system. The implementation cost and savings related to this ECM are presented in Appendix E and summarized as follows: New Jersey BPU Springfield Board of Education- Energy Audit 19 P age

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. 7.2 Wind Small wind turbines use a horizontal axis propeller, or rotor, to capture the kinetic energy of the wind and convert it into rotary motion to drive a generator which usually is designed specifically for the wind turbine. The rotor consists of two or three blades, usually made from wood or fiberglass. These materials give the turbine the needed strength and flexibility, and have the added advantage of not interfering with television signals. The structural backbone of the wind turbine is the mainframe, and includes the slip-rings that connect the wind turbine, which rotates as it points into changing wind directions, and the fixed tower wiring. The tail aligns the rotor into the wind. To avoid turbulence and capture greater wind energy, turbines are mounted on towers. Turbines should be mounted at least 30 feet above any structure or natural feature within 300 feet of the New Jersey BPU Springfield Board of Education- Energy Audit 20 P age

25 installation. Smaller turbines can utilize shorter towers. For example, a 250-watt turbine may be mounted on a foot tower, while a 10 kw turbine will usually need a tower of feet. Tower designs include tubular or latticed, guyed or self-supporting. Wind turbine manufacturers also provide towers. The New Jersey Clean Energy Program for small wind installations has designated numerous preapproved wind turbines for installation in the State of New Jersey. Incentives for wind turbine installations are based on kilowatt hours saved in the first year. Systems sized under 16,000 kwh per year of production will receive a $3.20 per kwh incentive. Systems producing over 16,000 kwh will receive $51,200 for the first 16,000 kwh of production with an additional $0.50 per kwh up to a maximum cap of 750,000 kwh per year. This measure is not recommended due to space and code requirements. 7.3 Geothermal Geothermal heat pumps (GHP) transfer heat between the constant temperature of the earth and the building to maintain the building s interior space conditions. Below the surface of the earth throughout New Jersey the temperature remains in the low 50 F range throughout the year. This stable temperature provides a source for heat in the winter and a means to reject excess heat in the summer. With GHP systems, water is circulated between the building and the piping buried in the ground. The ground heat exchanger in a GHP system is made up of a closed or open loop pipe system. Most common is the closed loop in which high density polyethylene pipe is buried horizontally at 4-6 feet deep or vertically at 100 to 400 feet deep. These pipes are filled with an environmentally friendly antifreeze/water solution that acts as a heat exchanger. In the summer, the water picks up heat from the building and moves it to the ground. In the winter the system reverses and fluid picks up heat from the ground and moves it to the building. Heat pumps make collection and transfer of this heat to and from the building possible. To take advantage of a GHP system, the existing mechanical equipment would have to be removed or overhauled; and either a low temperature closed loop water source heat pump system or a water to water heat pump system would have to be installed to realize the benefit of the consistent temperature of the ground. This measure is not recommended because the extent of HVAC system renovation needed for implementation greatly outweighs the savings over the life of the equipment. 7.4 Combined Heat and Power Generation (CHP) Combined heat and power, cogeneration, is self-production of electricity on-site with beneficial recovery of the heat byproduct from the electrical generator. Common CHP equipment includes reciprocating engine-driven, micro turbines, steam turbines, and fuel cells. Typical CHP customers include industrial, commercial, institutional, educational institutions, and multifamily residential facilities. CHP systems that are commercially viable at the present time are sized approximately 50 kw and above, with numerous options in blocks grouped around 300 kw, 800 kw, 1,200 kw and larger. Typically, CHP systems are used to produce a portion of the electricity needed by a school some or all of the time, with the balance of electric needs satisfied by purchase from the grid. New Jersey BPU Springfield Board of Education- Energy Audit 21 P age

26 Any proposed CHP project will need to consider many factors, such as existing system load, use of thermal energy produced, system size, natural gas fuel availability, and proposed plant location. The school has sufficient need for electrical generation and the ability to use most of the thermal byproduct during the winter, thermal usage during the summer months is low. Thermal energy produced by the CHP plant in the warmer months will be wasted. An absorption chiller could be installed to utilize the heat to produce chilled water; however, there is no chilled water distribution system in the building. The most viable selection for a CHP plant at this location would be a reciprocating engine natural gas-fired unit. Purchasing this system and performing modifications to the existing HVAC and electrical systems would greatly outweigh the savings over the life of the equipment. This measure is not recommended based on the relatively low electrical and thermal usage of the school, the lack of a need for simultaneous heating and cooling and the low occupancy during the summer months. 7.5 Biomass Power Generation Biomass power generation is a process in which waste organic materials are used to produce electricity or thermal energy. These materials would otherwise be sent to the landfill or expelled to the atmosphere. To participate in NJCEP's Customer On-Site Renewable Energy program, participants must install an on-site sustainable biomass or fuel cell energy generation system. Incentives for bio-power installations are available to support up to 1MW-dc of rated capacity. *Class I organic residues are eligible for funding through the NJCEP CORE program. Class I wastes include the following renewable supply of organic material: Wood wastes not adulterated with chemicals, glues or adhesives Agricultural residues (corn stover, rice hulls or nut shells, manures, poultry litter, horse manure, etc) and/or methane gases from landfills Food wastes Municipal tree trimming and grass clipping wastes Paper and cardboard wastes Non adulterated construction wood wastes, pallets The NJDEP evaluates biomass resources not identified in the RPS. Examples of eligible facilities for a CORE incentive include: Digestion of sewage sludge Landfill gas facilities Combustion of wood wastes to steam turbine Gasification of wood wastes to reciprocating engine Gasification or pyrolysis of bio-solid wastes to generation equipment * from NJOCE Website New Jersey BPU Springfield Board of Education- Energy Audit 22 P age

27 This measure is not recommended due to noise issues and because the school does not have a steady waste stream to utilize as a fuel source. 7.6 Demand Response Curtailment Presently, Electricity is delivered by JCP&L (Jersey Central Power & Lighting) and Gas Public Service Enterprise Group (PSE&G), which receives the electricity from regional power grid RFC. PSE&G 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 school 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 May 2011 through April 2012 the school had a peak electricity demand of 73.7 kw and a minimum of 40.0 kw. The monthly average over the observed 12 month period was 58.0 kw. This measure is not recommended. New Jersey BPU Springfield Board of Education- Energy Audit 23 P age

28 8.0 EPA PORTFOLIO MANAGER The EPA Portfolio Manager benchmarking tool was used to assess the building s energy performance. Portfolio Manager provides a site and 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 being 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 delivered to a school 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 accounts for losses incurred in production, storage, transmission, and delivery of energy to the site, which provide an equivalent measure for various types of buildings with differing energy sources. The results of the Portfolio Manager benchmarking tool are contained in the table below. Building Site EUI kbtu/ft 2 /yr Source EUI Btu/ft 2 /yr James Caldwell Elementary School Energy Star Rating (1-100) The James Caldwell Elementary School has an 62 average site EUI and therefore an above average Energy Star Rating Score of 57 (50 being the median score). This is most likely attributed to the building envelope. 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 ( A full EPA Energy Star Portfolio Manager Report is located in Appendix F.
