7 2.0 INTRODUCTION AND BACKGROUND The Woods Road Elementary School building is a single story 58,000 square foot facility. Woods Road Elementary School was originally constructed in 1967, and consists of perimeter classrooms surrounding a cafeteria, library, and other core spaces. The school was expanded in 1994 with a classroom and gymnasium wing to the west of the original building. The school hours of operation are from 8:30 AM 3:05 PM Monday through Friday, with various afterschool activities. The building is occupied approximately 10 hours per day Monday through Friday; totaling 5060 hours per week. The school has approximately 430 students and 85 facility members. New Jersey s Clean Energy Program, funded by the New Jersey Board of Public Utilities, supports energy efficiency and sustainability for Municipal and Local Government Energy Audits. Through the support of a utility trust fund, New Jersey is able to assist state and local authorities in reducing energy consumption while increasing comfort. New Jersey BPU Energy Audits 7

8 3.0 EXISTING CONDITIONS 3.1 Building General The building envelopes of the main building and the addition are constructed of 6 block walls (CMU), 2 rigid insulation, 2 air space, 4 CMU and plaster. The majority of the interior walls are also painted plaster walls. The roof is constructed of metal roof decking, 2.5 isocyanurate insulation, and a fully adhered 0.60 EPDM roofing membrane system. The roof over the original building was replaced in The area over the gym was redetailed in The rest of the roof has surpassed its useful life and needs to be replaced per the ARMM Associates assessment, provided by the school district. Windows and doors have been upgraded within the last decade. Windows are double pane glazing with an aluminum frame. 3.2 Utility Usage Utilities include electricity, natural gas, and potable water. Electricity is delivered by Public Service Electric and Gas (PSE&G) and supplied by Direct Energy. Natural gas supplied by Hess and Woodruff Energy and delivered by PSE&G. Water is paid for through New Jersey American Water. The school has one electric meter serving the site. From June 2011 through May 2012, the electric usage for the facility was approximately 378,800 kwh at a cost of about $57,300. Review of electricity bills during this period showed that the facility was charged at the following rates: supply unit cost of $0.125 per kwh; demand unit cost of $6.83 per kw; and blended unit cost of $0.151 per kwh. Electrical usage was generally higher in the winter months when heating equipment was operational. From June 2011 through May 2012, gasfired equipment consumed about 21,700 therms of natural gas. Based on the annual cost of about $20,900, the blended price for natural gas was $0.96 per therm. Natural gas consumption was highest in winter months for heating. See Appendix A for a detailed utility analysis. The delivery component of the electric and natural gas bills will always be the responsibility of the utility that connects the facility to the power grid or gas line; however, the supply can be purchased from a third party; as is currently the case with electricity and natural gas. The electricity or natural gas commodity supply entity will require submission of one to three years of past energy bills. Contract terms can vary among suppliers. According to the U.S. Energy Information Administration, the average commercial unit costs of electricity and natural gas in New Jersey during the same periods as those noted above was $0.141 per kwh and $0.959 per therm. When compared to the average state values, it is recommended that the present natural gas and electricity supply rate be maintained. 3.3 HVAC Systems Boilers produce hot water which is used to heat the school. The school is served by three gas fired boilers; two (2) WeilMcLain 764 MBtu/hr boilers that were installed when the building was expanded in 1994, and one (1) HB Smith 2,378 MBtu/hr boiler that is original to the school s 1967 construction. The two Weil McLain boilers appear to be in good condition. The 1967 HB New Jersey BPU Energy Audits 8

9 Smith boiler also appears to be in good condition but has reached its useful life. These boilers are controlled using a hot water reset schedule based on outdoor air temperature, but can only be reset to provide 160 F supply water, as they are noncondensing boilers. The hot water is pumped throughout the addition by two (2) 2 HP pumps, which operate in a lead/ lag fashion and by a single 3HP pump for the original building. The electrical efficiency of these pumps is 87.5%. The heating hot water is distributed to classroom unit ventilators, cabinet unit heaters, perimeter fin tube radiation and larger heating and ventilating units (HV) serving the gym. The classroom unit ventilators are the same vintages as the original building and the addition. Of the school s 58,000 square feet, approximately 33%, or 19,000 square feet, is provided with mechanical cooling. Most classrooms are provided with window mounted air conditioners having a capacity of approximately 12,000 BTU/hr. Support spaces such as the administration offices, guidance office, nurses office, library and faculty room are provided with cooling from either ducted or ductless split DX systems which have air cooled condenser units mounted on the roof. These units range in size from 18,000 BTU/hr up to 72,000 BTU/hr. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B. 3.4 Control Systems The mechanical systems of the building are controlled by antiquated pneumatic controls that are supplied with air constantly be a single air compressor. It was reported by maintenance staff that there are many leaks in the system which result in excessive compressor operation and poor temperature regulation. It appears that the entire system is time clock controlled to set the temperatures down (up) during unoccupied times. The building is maintained at 6872 F in in occupied heating and 55 F in unoccupied heating mode. Cooling is generally set to maintain 74 F during occupied times and off when the building is not occupied. 3.5 Lighting/Electrical Systems The facility has upgraded incandescent fixtures to compact florescent lighting (CFLs). The ballasts have been upgraded from magnetic to electronic as well. A majority of the lighting fixtures in instructional areas, office spaces, corridors, etc., are T8 fluorescent fixtures, with specialty lighting in the gymnasiums and building exterior. The gym has 400W metal halides. There are also a very small percentage of ancillary areas lit from incandescent bulbs. The majority of lights are switched manually; exception is the gymnasium. Parking lot lighting consists of pole mounted high pressure sodium light fixtures which are on a timer. The building exterior utilizes 150W high pressure sodium and 75W incandescent lamps. 3.6 Plumbing Systems The domestic hot water needs of the original main portion of the building is served by a 250 gallon indirect water heater /storage tank that is supplied with hot water from the heating boilers year round. The addition is served by a single A.O Smith 100 gallon tank type hot water heater New Jersey BPU Energy Audits 9

10 having an input of 78 MBH installed in This unit is standard 80% efficiency but appears to be in good condition. The water closets lavatories and urinals in the original 1967 portion of the school are of the same vintage and have high flow flush valves and faucets. These fixtures are in fair visual condition. The 1994 addition have plumbing fixtures of the same vintage and are compliant with the EPAct 1992 Energy Code. New Jersey BPU Energy Audits 10

11 4.0 ENERGY CONSERVATION MEASURES 4.1 ECM1 Boiler Replacement for Original Building The original building is served by a single HB Smith boiler that was installed in The boiler is in god condition but has exceeded its useful life. The thermal efficiency of this boiler is about 82% however is appears oversized for the area that it serves, making it less efficient. This ECM assesses the replacement of the old boiler with a single high efficiency condensing boiler, sized appropriately. Condensing boilers have the ability to run at low water temperatures enabling them to take full advantage of a more aggressive hot water reset schedule. This calculation is based on a comparison of the estimated boiler gas consumption and efficiency with a new smaller capacity boiler having increase efficiency. The result is a savings in natural gas consumption. Natural gasfired boilers have an expected life of 25 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 45,000 therms of natural gas and $45,000. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM1 Boiler Replacement for Original Building Budgetary Annual Utility Savings Estimated Total Potential Payback Payback Cost Maintenance Savings ROI Incentive* (without (with Incentiv Electricity Natural Gas Water Total Savings e) Incentive) $ kw kwh Therms Gals $ $ $ $ Years Years 163, , , ,800 (0.7) 3,000 >20 >20 * Incentive shown is per the New Jersey SmartStart Program. See section 5.0 for other incentive opportunities This measure is recommended based on the age and condition of the equipment. 4.2 ECM2 Add Condensing Boiler to Addition for Shoulder Months The addition is served by two Weil McLain boilers. These boiler were installed in 1994 and are in good condition, however they are standard 82% 84% efficiency. This ECM assesses adding a supplemental condensing boiler to act as the primary boiler while maintaining the two older boilers as secondary heat sources. The condensing boilers will operate at higher efficiencies when producing lower water temperatures, such as those needed during the shoulder months of September November, March and April when the outdoor temperature is moderate, versus the older boilers constant 8284%. This new boiler and pump would be sized to meet 100 % of the peak heating load requirements of the addition, although it would rarely operate at full capacity. The increased system efficiency will result in lower natural gas usage. Natural gasfired boilers have an expected life of 25 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 5,000 therms of natural gas and $5,000. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: New Jersey BPU Energy Audits 11

12 ECM2 Add Condensing Boiler to Expansion for Shoulder Months Budgetary Annual Utility Savings Estimated Total Potential Payback Payback Cost Maintenance Savings ROI Incentive* (without (with Incentiv Electricity Natural Gas Water Total Savings e) Incentive) $ kw kwh Therms Gals $ $ $ $ Years Years 154, (1.0) 3,000 >20 >20 * Incentive shown is per the New Jersey SmartStart Program. See section 5.0 for other incentive opportunities This measure is not recommended due to the high payback period. 4.3 ECM3 Domestic Hot Water System Improvements The original building wing has a 250 gallon storage tank that is connected to the hot water piping system. The original building domestic hot water is produced by a single HB Smith boiler that was installed in The boiler typically operates from October 15 April 15. The tank storage capacity is significantly oversized based on typical elementary school usage and has somewhat lower system efficiency than the boiler efficiency alone. Converting to a high efficiency instantaneous water heater would provide adequate hot water and reduce gas consumption. The piping from this the new water heater can be tied directly into the domestic hot water system, eliminating the connections to the boilers. The 1994 addition utilizes an A.O Smith BTR110 tank type water heater having an input of 78 MBH and a capacity of 100 gallons. This water heater has an overall efficiency of 80% and can also be replaced with an instantaneous type water heater having an efficiency of 9596 %. The new water heaters will require gas and water piping modifications, venting, and electrical connections. According to the U.S. Department of Energy, 2.5% of stored capacity is lost every hour during standby when the water heater is not in use. This value was applied to the total volume of the existing domestic hot water storage tanks to determine the annual standby losses. The proposed efficiency is based on a typical instantaneous hot water heater at 94%. Results of the calculations show 600 therms of natural gas would be saved per year. Domestic hot water heaters have an expected life of 12 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 4,800 therms and $4,800. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM3 Domestic Hot Water System Improvements Budgetary Annual Utility Savings Estimated Total Potential Payback Payback Cost Maintenance Savings ROI Incentive* (without (with Electricity Natural Gas Water Total Savings Incentive) Incentive) $ kw kwh Therms Gals $ $ $ $ Years Years 17, (0.2) 600 >20 >20 * Incentive shown is per the New Jersey SmartStart Program. See section 5.0 for other incentive opportunities. New Jersey BPU Energy Audits 12

13 This measure is not recommended 4.4 ECM4 Replace Window A/C Units with a Ductless Splits System Some Classrooms are conditioned by a 12,000 BTU/hr window mounted air conditioners. The school has approximately 25 of these units. These units are estimated to have an efficiency of 9.0 SEER and their condition appears to be fair to poor. This ECM assesses replacing (1) window unit with a high efficiency, ductless split A/C system. 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. Ductless split systems units have an expected life of 15 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 43,500 kwh and $6,000. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM4 Replace Window A/C Unit with a Ductless Split System Budgetary Annual Utility Savings Estimated Total Potential Payback Payback Cost Maintenance Savings ROI Incentive* (without (with Electricity Natural Gas Water Total Savings Incentive) Incentive) $ kw kwh Therms Gals $ $ $ $ Years Years 3, (0.9) 100 >20 >20 * Incentive shown is per the New Jersey SmartStart Program. See section 5.0 for other incentive opportunities. This measure is recommended if the long term plan is to add air conditioning to all of the classrooms. 4.5 ECM5 Replace Direct Expansion (DX) Split Systems The school has several ducted split systems to provide cooling to larger spaces. These units are less efficient that there current counterparts. Also the units use R22 refrigerant, which is being phased out of production and will become exceedingly expensive. The replacement units are the same capacity, use environmentally friendly 410A refrigerant and have higher energy efficiencies. It is recommended that the these split system condensing units be replaced through attrition with higher energy efficiency ratio (EER) models. This ECM looks at replacing each size of split system and gives the energy savings opportunity. To gather the total energy savings each type should be multiplied by the number of units of that type. 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. Split systems units have an expected life of 15 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 21,000 kwh and $3,000. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: New Jersey BPU Energy Audits 13

See section 5.0 for other incentive opportunities. This measure is recommended through attrition. 4.6 ECM6 Upgrade Controls The building currently uses older pneumatic controls to operate the HVAC systems. The pneumatic air lines are leaking which requires the air compressor to operate excessively and contributes to poor temperature regulation. The pneumatic control valves and damper actuators have exceeded their useful life and may not operate as intended. This ECM assesses the replacement of the failing pneumatic controls system and air compressor with modern direct digital controls (DDC) which can be integrated into the District s current Building Automation System. The new system will provide more accurate temperature regulation and provide for remote scheduling, which would allow the District to take advantage of their current third party New Jersey BPU Energy Audits 14

15 controls management firm. This calculation estimates the fuel savings based on similar projects and data provided by the third party controls management firm. Digital controls have an expected life of 15 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 160,500 kwh, 145,500 therms and $165,000. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM6 Upgrade Controls Budgetary Annual Utility Savings Estimated Total Payback Payback Cost Maintenance Savings ROI Incentive* (without (with Electric Electric Nat Gas Total Savings incentive) incentive) $ kwh kw Therms $ $ $ $ Years Years 25,000 10, ,700 11, , * Does not qualify for an Incentive per the New Jersey SmartStart Program. See section 5.0 for other incentive opportunities. This measure is recommended. 4.7 ECM7 Demand Controlled Ventilation (DCV) for Gym The Gym has two dedicated heating and ventilation (HV) units that are heated by the boilers. The HV units are designed to provide adequate ventilation air for maximum occupancy which does not occur often. By reducing the amount of cold outside air during semi occupied times will reduce heating energy. The quantity of ventilation can be based on maintaining an acceptable Carbon dioxide (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 could be installed to measure the space CO 2 concentration and used to control the outdoor air dampers on the HV units. During unoccupied periods, the outside air dampers would be closed. Bin weather data was utilized to obtain the estimated 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 CO2 controls will reduce the amount of OA to be conditioned by 20% from the original design quantity. The energy saving is the difference in natural gas usage. Controls have an expected life of 15 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 22,500 therms and $22,500. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: New Jersey BPU Energy Audits 15

See section 5.0 for other incentive opportunities. This measure is recommended. 4.8 ECM8 Lighting Replacement / Upgrades The facility has upgraded incandescent fixtures to compact florescent lighting (CFLs). The ballasts have been upgraded from magnetic to electronic as well. A majority of the lighting fixtures in instructional areas, office spaces, corridors, etc., are T8 fluorescent fixtures, with specialty lighting in the gymnasiums and building exterior. There are also a very small percentage of ancillary areas lit from incandescent bulbs. The majority of lights are switched manually; exception is the gymnasium. A comprehensive fixture survey was conducted of the entire building. Each switch and circuit was identified, and the number of fixtures, locations, and existing wattage established (Appendix C). There is an opportunity to continue to reduce consumption more by upgrading the classrooms to a super T8 fixture. Energy savings for this measure were calculated by applying the existing and proposed fixture wattages to estimated times of operation. The difference between energy requirements resulted in a total annual savings of 15,100 kwh with an electrical demand reduction of about 6.0 kw. Supporting calculations, including assumptions for lighting hours and annual energy usage for each fixture, are provided in Appendix C. Lighting has an expected life of 15 years, according to the manufacturer, and total energy savings over the life of the project are estimated at 226,500 kwh and $36,000.

See section 5.0 for other incentive opportunities. This measure is not recommended in lieu of ECM ECM9 Install Lighting Controls (Occupancy Sensors) Review of the comprehensive lighting survey determined that lighting in classrooms, restrooms, and various other spaces, are typically operational, regardless of occupancy. Therefore, installing New Jersey BPU Energy Audits 16

17 an occupancy sensor in these spaces to turn off lights when the areas are unoccupied was assessed. Using a process similar to that utilized in section 4.8, the energy savings for this measure were 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 45,900 kwh. Ceilingmounted occupancy sensors with dimmer control are required for this measure. Occupancy sensors have an expected life of 15 years, according to the manufacturer, and total energy savings over the life of the project are estimated at 688,500 kwh and $87,000.

18 4.11 ECM11 Roof Replacement The roof is constructed of metal roof decking, 2.5 isocyanurate insulation, and a fully adhered 0.60 EPDM roofing membrane system. The roof over the original building was replaced in The area over the gym was redetailed in The rest of the roof has surpassed its useful life and needs to be replaced per the ARMM Associates assessment. 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 facility was found using the existing roof s Rvalue of 13.0 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 Rvalue of 18.0 The annual energy savings of replacing the roof is detailed in the summary table below. A roof has an expected life of 30 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 9,000 kwh, 15,000 therms, and $15, 0001,185,000.

19 5.0 PROJECT INCENTIVES 5.1 Incentives Overview New Jersey Pay For Performance Program 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 nonprofit 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. 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: PostConstruction 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. New Jersey BPU Energy Audits 19

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 $5,800 Incentive #2 $7,669 $17,953 $25,622 Incentive #3 $7,669 $17,953 $25,622 Total $15,339 $35,906 $157,044 The current ECM s meets the minimum savings of 15% and therefore the building would be eligible for incentives #2 and #3. See Appendix D for additional details. A separate calculation was done which didn t include the roof replacement measure. The results are shown in Appendix D New Jersey Smart Start Program For this program, specific incentives for energy conservation measures are calculated on an individual basis utilizing the 201 New Jersey Smart Start incentive program. This program provides incentives dependent upon mechanical and electrical equipment. If applicable, incentives from this program are reflected in the ECM summaries and attached appendices. If the facility qualifies and enters into the New Jersey Pay for Performance Program, all energy savings will be included in the total site energy reduction, and savings will be applied towards the Pay for Performance incentive. A project is not applicable for both New Jersey incentive programs. The facility is eligible for several incentives available under New Jersey Smart Start Programs. The total amount of all qualified incentives is about $4, Direct Install Program The Direct Install Program targets small and medium sized facilities where the peak electrical demand does not exceed 150 kw 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. On a New Jersey BPU Energy Audits 20

21 casebycase basis, the program manager may accept a project for a customer that is within 10% of the 150 kw peak demand threshold. 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 significantly reduce the implementation cost of energy conservation projects. The program pays 70% of each project cost up to $75,000 per electrical utility account; total funding for each year is capped at $250,000 per customer. Installations must be completed by a Direct Install participating contractor, a list of which can be found on the New Jersey Clean Energy Website at Contractors will coordinate with the applicant to arrange installation of recommended measures identified in a previous energy assessment, such as this document. This program is applicable to the school based on the school s average peak demand of kw Energy Savings Improvement Plans (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 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 (see Appendix E). 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. New Jersey BPU Energy Audits 21

22 6.0 ALTERNATIVE ENERGY SCREENING EVALUATION 6.1 Solar Photovoltaic Rooftop Solar Power Generation The facility 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 large solar cell array. The PVWATTS solar power generation model was utilized to calculate PV power generation. The closest city available in the model is Newark, New Jersey and a fixed tilt array type was utilized to calculate energy production. Federal tax credits are also available for renewable energy projects up to 30% of installation cost. Since the facility does not pay taxes this project is not eligible for this incentive. 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) solarproducers. 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. The average SREC value per credit is estimated to be about $95/ SREC per year based on current market data, and this number was utilized in the cash flow for this report. The existing load justifies the use of a 300 kw PV solar array. The system costs for PV installations were derived from contractor budgetary pricing in the state of New Jersey for estimates of total cost of system installation. It should be noted that the cost of installation is currently about $4.00 per watt or $4,000 per kw of installed system. Other cost considerations will also need to be considered. 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 need to be replaced multiple times 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: Photovoltaic (PV) Rooftop Solar Power Generation 300 kw System Budgetary Annual Utility Savings Total Cost Electricity Natural Gas Total Savings New Jersey Renewable Energy Incentive* New Jersey Renewable Payback Payback SREC** (without incentive) (with incentives) $ kw kwh Therms $ $ $ $ Years Years 1,280, , ,578 56, ,102 > ** Estimated Solar Renewable Energy Certificate Program (SREC) for 15 years at $75/1000 kwh New Jersey BPU Energy Audits 22

23 This measure is not recommended due to the long payback time. It is suggested, however, that the market for SREC credits is closely monitored. This market is fluctuating, and if the value per SREC is increased the measure could potentially show for a shorter payback in the near future Solar Thermal Hot Water Plant 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 Public Service Electric and Gas (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 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 preapproved CSP will require a minimum of 100 kw of load reduction to participate in any curtailment program. From June 2011 through May 2012 the facility had a maximum electricity demand of kw and a minimum of 75.6 kw. The monthly average over the observed 12 month period was kw. This measure is not recommended. New Jersey BPU Energy Audits 23

24 7.0 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 facility 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 Energy Star Rating (1100) Woods Road Elementary School The facility has an above average EUI. By implementing the measures discussed in this report, it is expected that the EUI can be reduced. The Portfolio Manager account can be accessed by entering the username and password shown below at the login screen of the Portfolio Manager website ( The account has been shared with the NYSERDABENCHMARKING master account.
