6 2.0 INTRODUCTION AND BACKGROUND 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. The elementary school located in Englewood Cliffs, NJ, is a 24,971 square foot single story block structure with a high bay gym and multipurpose room. H VAC equipment is located on the ground outside the gym, on t he roof, and in the mechanical room. The high bay gym and all purpose room condensers are located on the ground adjacent to the gym. The building was constructed in Occupancy includes approximately 215 students and 30 full time staff. The school operates Monday through Friday from 8:00 AM to approximately 3:00 PM, with some afterschool use. New Jersey BPU - Energy Audits Page 5 of 33

7 3.0 EXISTING CONDITIONS 3.1 Building - General Built in 1963, the 24,971 square foot, one-story facility has high bay areas for the multipurpose room (gym, auditorium, and cafeteria). The spaces include classrooms, administrative offices, small kitchen, and support spaces. The following block diagram/drawing (not to scale) shows the general school layout. NORTH The school has approximately 215 students and 30 full time staff, and appeared fully utilized during the field survey. The building can be assumed to be fully occupied by about 245 people from 8:00 AM until 3:00 PM during the week, and on Saturday and Sunday for the gym. Custodial staff is in the building for approximately three hours after 3:00 PM during the week. The building is constructed of masonry walls having a brick veneer and a structural steel roof framing system. With the exception of the multipurpose room, the roof is flat and has an asphalt sheet roof covering. The multipurpose room has a cathedral ceiling with wood rafters and tongue and groove interior wood finish, and residential type asphalt shingles at the exterior. The windows and doors were replaced in 2007 during a major capital improvement project. The windows are double glazed aluminum framed and have insulated fiberglass reinforced plastic (FRP) panels. The doors are also insulated FRP. 3.2 Utility Usage Utilities include electricity, natural gas, and potable water. Electricity is delivered by PSE&G and supplied by SJEC. Natural gas is delivered by PSE&G and supplied by Hess. Potable water is provided New Jersey BPU - Energy Audits Page 6 of 33

8 by the municipally owned water department at a charge. See Appendix A for a detailed elementary school utility analysis. The school has one electric meter. Electrical usage for October 2010 through September 2011 was approximately 240,810 kwh at a cost of about $25,200. Review of electricity bills during this period showed that electricity was charged at the following rates: supply unit consumption cost of $0.136 per kwh; demand unit cost of $7.51 per kw; and blended unit cost of $0.154 per kwh. From October 2010 through September 2011, the elementary school had a m aximum electrical demand of kw and minimum of kw. The monthly average over the observed 12 m onth period was kw. Electrical usage was generally higher in the summer months when air conditioning equipment was operational. The school has one natural gas meter. From October 2010 through September 2011, gas-fired equipment consumed about 16,690 therms of natural gas. Based on the annual cost of $16,400, the blended price for natural gas was $0.98 per therm. Natural gas consumption was highest in winter months for heating. Potable water billing data was not received from the client. Rather, an average water usage rate was obtained from the Englewood Cliffs public utility as $3.29 per 1000gallons. 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 $ per kwh and $0.954 per therm. The electrical supply rate charged by SJEC for the 12 month period from October 2010 through September 2011 resulted in a lower cost to the school district than having PSE&G provide both supply and delivery (see table below). When compared to the average state values, it is recommended that the present natural gas be maintained and the present electricity supply rate charge be monitored and checked monthly. Elementary School Electric Supply Costs SJEC vs. PSE&G Electricity Consumption (kwh) SJEC Supply Costs (Actual) PSE&G Supply Costs (For Comparison) Month October ,460 $10, $9, November-10 22,680 $2, $2, December-10 12,540 $1, $1, January-11 12,660 $1, $1, February-11 11,250 $1, $1, March-11 12,150 $1, $1, April-11 10,530 $1, $1, May-11 11,160 $1, $1, June-11 12,450 $1, $1, July-11 9,240 $ $1, August-11 5,130 $ $ September-11 19,560 $1, $2, Total 240,810 $25, $25, Savings by using SJEC for electric supply $ New Jersey BPU - Energy Audits Page 7 of 33

9 A list of approved electrical and natural gas energy commodity suppliers can be found in Appendix A. 3.3 HVAC Systems The systems and equipment described below serve the building. Specifics on the mechanical equipment can be found within the equipment inventory located in Appendix B Heating Hot Water Systems The heating system consists of two Eastco fire tube boilers having Power Flame full modulation gas burners. The boilers have an input capacity of 3,344 MBH. The heating system uses two 2 HP pumps that distribute the heating hot water to all terminal units. The pumps and boilers operate in a lead/lag manner. A Heat Timer Multi-Mod Platinum boiler controller provides the boiler and pump enable/disable, lead/lag, and hot water reset control sequences. A digital three-way mixing valve enables the boiler water to mix with the heating loop water to provide loop water temperature reset. The heating hot water is pumped to heating only classroom unit ventilators, perimeter fintube radiators, and small cabinet heaters in corridors and vestibules. There are exterior wall exposures that are heated by perimeter hot water fintube radiators with wall mounted thermostats. Corridors, entrance vestibules, and some rooms are heated by ceiling mounted hot water cabinet unit heaters controlled by space thermostats. There is no central air handling system in this building Ductless Split System Air Conditioning Systems Cooling is provided in the library and multipurpose room by individual ductless split system air conditioning systems. The library has a 36,000 Btuh system and the multipurpose room has four 60,000 Btuh systems. The faculty lounge also has a small 9,000 Btu/h Fujitsu ductless split system air conditioning unit Window Air Conditioning Units Some rooms and spaces have window air conditioning units installed to provide additional cooling. The main office, nurse s office, and resource rooms each have residential window air conditioners ranging in size from 5,000 12,000 Btuh Exhaust Systems Exhaust fans are used for restrooms and custodial closets throughout the building. There are small restrooms in most of the classrooms for the students and separate adult and faculty restrooms with standard exhausts. 3.4 Control Systems The building has an Automated Logic direct digital controls (DDC) system that only manages the classroom unit ventilators. The perimeter fintube radiators have self-contained control valves that are manually adjusted by the teachers. All cooling systems are also manually controlled by the staff. Occupied space temperatures are maintained at F heating and F cooling, 5:00 AM to 8:00 PM during the school year. Unoccupied heating temperatures are maintained the same as occupied, and cooling is manually turned on by t he teachers in the morning and turned off by the maintenance staff at 8:00 PM during summer months. New Jersey BPU - Energy Audits Page 8 of 33

10 The boilers and pumps are independently controlled by the Heat Timer controls. 3.5 Lighting/Electrical Systems Since building construction, the facility has reballasted and relamped all fixtures. The facility primarily utilizes fixtures with T-8 32 watt bulbs, compact fluorescent spiral bulbs; older style incandescent bulbs are also used in select areas. Four feet, 4 lamp T-8 light fixtures are used in the high bay gym. The primary source of control for the lights is switches manually turned off at the end of the school day. Exterior lights consist mainly of wall mounted shoebox type metal halides on Tork timers, incandescent lightbulbs, and some LED spotlights. The wall mounted metal halide lights, incandescent lightbulbs, and LED lights are powered by the building s electrical system and are part of the lighting systems analysis. 3.6 Plumbing Systems Domestic Hot Water System The building has an independent domestic hot water heating system. The system consists of an RBI gas fired boiler that has a gross input capacity of 530,000 BTU/h. The boiler produces 150 F hot water that is stored in a 119 gallon glass-lined storage tank at approximately 130 F. A small 1/6 HP pump circulates the water between the boiler and storage tank. The 130 F hot water is then mixed with cold water at a master mixing valve and distributed to the plumbing fixtures at 105 F. A separate 1/4 HP pump circulates the 105 F domestic hot water to the fixtures. This pump is controlled by water temperature Plumbing Fixtures The building has several student and staff restrooms. There are also small restrooms within some classrooms. Cooking or dishwashing is not performed. The majority of the plumbing fixtures are the same vintage as the building construction. The water closets and urinals use older manual flush valves that are assumed to be 3.5 gallons per flush or greater. All lavatories use older metered faucets that flow at least 3 gallons per minute and operate for seconds. Janitor closets are provided with mop sinks and faucets. The small warming kitchen and classrooms have residential type stainless steel sinks and faucets. New Jersey BPU - Energy Audits Page 9 of 33

11 4.0 ENERGY CONSERVATION MEASURES 4.1 ECM-1 Install HVAC Occupancy Sensors The HVAC system is controlled by a DDC system that only controls the unit ventilators in the classrooms. O ccupied space temperatures are maintained at F heating and F cooling. Occupied temperatures are maintained the same as u noccupied. T his measure assessed installing occupancy sensors that would automatically dial back the heating of spaces when they are unoccupied. This will reduce natural gas consumption during the heating months and electrical consumption during the cooling months. These sensors would not be used to control the ventilation quantity for each classroom. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM-1 Install HVAC Occupancy Sensors Budgetary Estimated Total Payback Payback Cost Annual Utility Savings Maintenance Savings ROI Incentive * (without (with Electric Electric Nat Gas Total Savings incentive) incentive) $ kwh kw Therms $ $ $ $ Years Years 18,000 7, $ 2, , Expected Life: 25 years Lifetime Savings: 188,200 kwh 20,800 therms $ 52,500 * Incentive shown is per the New Jersey Smart Start Program. See section 5.0 for other incentive opportunities. This measure is recommended. 4.2 ECM-2 HVAC Condensing Boiler Addition The school is heated by two Eastco fire tube boilers having Power Flame full modulation gas burners. The boilers have an input capacity of 3,344 M BH. The heating system contains two 2 H P pumps that distribute the heating hot water to all of the terminal units. The boilers each have efficiencies of 80%. Due to the relatively low efficiency of the two existing boilers, an evaluation was performed for adding one high efficiency condensing boiler to operate as the primary boiler during the shoulder months (March-May and September-November) with the existing two boilers operating as secondary. The majority of the savings will be achieved during these months when the lower return water temperature enables the condensing boiler to achieve the highest efficiencies. The boiler fuel consumption was calculated from the natural gas used annually for the shoulder months per utility bills and boiler efficiency. The results were compared to the improved operating efficiency of a new condensing boiler. The difference in fuel usage was the savings. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: New Jersey BPU - Energy Audits Page 10 of 33

12 ECM-2 Budgetary Install Condensing Boiler for Shoulder Months Estimated Total Payback Payback Cost Annual Utility Savings Maintenance Savings ROI Incentive * (without (with Electric Electric Nat Gas Total Savings incentive) incentive) $ kwh kw Therms $ $ $ $ Years Years 39, $ (0.9) 2,900 >20 >20 Expected Life: 25 years Lifetime Savings: 0 kwh 4,000 therms $ 5,000 * Incentive shown is per the New Jersey Smart Start Program. See section 5.0 for other incentive opportunities. This measure is not recommended. 4.3 ECM-3 Install Hot Water Reset Controller on Condensing Boiler This ECM evaluated installation of hot water reset in conjunction with the addition of condensing boilers to the system (ECM-2). The purpose of hot water reset is to modulate the heating hot water temperature depending on the outdoor air temperature; on a warmer day, the boiler can produce lower temperature heating hot water to meet heating demands. Savings were determined through improved boiler efficiency as the heating hot water temperature decreased. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM-3 Install a Hot Water Reset Controller on Condensing Boiler Budgetary Estimated Total Payback Payback Cost Annual Utility Savings Maintenance Savings ROI Incentive * (without (with Nat Electric Electric Gas Total Savings incentive) incentive) $ kwh kw Therms $ $ $ $ Years Years 1, $ (0.1) Expected Life: 15 years Lifetime Savings: 0 kwh 900 therms $ 1,500 * Does not qualify for an Incentive per the New Jersey SmartStart Program. See section 5.0 for other incentive opportunities. This measure is not recommended because of interaction with ECM ECM-4 Install High Efficiency Domestic Hot Water Heater The school has one domestic hot water heater that provides hot water to the facility. The RBI unit is tank type, natural gas standard efficiency, with an input of 530 MBH. During periods of little or no domestic hot water use, the unit must still heat the water within the storage tank. Energy required maintaining the 119 gallons of hot water temperature setpoint during times of zero demand is known as standby losses; replacing this unit with a higher efficiency condensing natural gas unit was evaluated. According to the U.S. Department of Energy, 2.5% of stored capacity is lost every hour during hot water heater standby. This value was applied to the total volume of the existing DHW heater storage tank to determine the annual standby losses. Proposed efficiency was based on a typical tank type, high New Jersey BPU - Energy Audits Page 11 of 33

13 efficiency, condensing hot water heater; it was calculated that 650 therms of natural gas would be saved per year. The new water heater will require gas and water piping modifications, venting, and electrical connections. The implementation cost and savings related to this ECM are presented in Appendix C and summarized as follows: ECM-4 Install High Efficiency Domestic Hot Water Heater Budgetary Estimated Total Payback Payback Cost Annual Utility Savings Maintenance Savings ROI Incentive * (without (with Electric Electric Nat Gas Total Savings incentive) incentive) $ kwh kw Therms $ $ $ $ Years Years 4, $ Expected Life: 12 years Lifetime Savings: 0 kwh 7,900 therms $ 8,400 * Incentive shown is per the New Jersey SmartStart Program. See section 5.0 for other incentive opportunities. This measure is recommended. 4.5 ECM-5 Install Insulation in Ceiling The roof is constructed of flat asphalt sheets with minimal insulating board, and concrete decking. This ECM addressed installing 6 thick fiberglass insulation (R-19) between the joists of the ceiling to minimize heating losses. To calculate the savings, the heat losses through the roof assembly of the facility was found using an estimated roof R-value of 5 and bin weather data for nearby Newark, NJ. The values were totaled to determine the existing annual energy losses. Heating energy loss values were then determined with a thermal resistance which included the additional R-19 fiberglass insulation. The annual energy savings of installing insulation in between the ceiling joists is expected to be about 5,500 therms. The implementation cost and savings related to this ECM are presented in Appendix C and summarized as follows: ECM-5 Install Insulation in Ceiling Budgetary Estimated Total Payback Payback Cost Annual Utility Savings Maintenance Savings ROI Incentive * (without (with Electric Electric Nat Gas Total Savings incentive) incentive) $ kwh kw Therms $ $ $ $ Years Years 20, ,550 $ 5, , Expected Life: 35 years Lifetime Savings: 0 kwh 194,300 therms $ 192,500 * Does not qualify for an Incentive per the New Jersey SmartStart Program. See section 5.0 for other incentive opportunities. This measure is recommended. New Jersey BPU - Energy Audits Page 12 of 33

14 4.6 ECM-6 Install Low Flow Plumbing Fixtures The facility has vintage 1963 plumbing fixtures in the restrooms. Older fixtures consume more water than modern units. It was determined that there is a combination of 32 toilets and urinals with an average water use of 3.25 gal/flush and 14 faucets with a water discharge rate of 3 gal/min. Per the number of occupants, it was estimated that each toilet and faucet is utilized approximately 2 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 cases. The basis of this calculation is the number of times each fixture is used, gallons per use, and number of fixtures. Replacing the existing fixtures in the restrooms with 1.6 gals/flush toilets, 1.0 gal/flush urinals, and 1.5 g al/min faucets would save 33 KGal annually. The implementation cost and savings related to this ECM are presented in Appendix C and summarized as follows: ECM-6 Install Low Flow Fixtures in Bathrooms Budgetary Estimated Total Payback Payback Cost Annual Utility Savings Maintenance Savings ROI Incentive * (without (with Electric Electric Water Total Savings incentive) incentive) $ kwh kw kgal $ $ $ $ Years Years 29, $ (0.9) 0 >20 >20 Expected Life: 15 years Lifetime Savings: 0 kwh 500 kgal $ 1,500 * Incentive shown is per the New Jersey SmartStart Program. See section 5.0 for other incentive opportunities. This measure is not recommended. 4.7 ECM-7 Install High Efficiency Condensing Units The facility uses split system direct expansion (DX) air conditioning equipment in the library and in the multipurpose room. T hese systems are rated at 11.0 EER and use more energy than higher SEER condensing units available today. It was determined that there are six DX units in place totaling 285 MBH of electric cooling. The electrical savings associated with replacing these units with higher EER condensing units was calculated by taking the difference in electrical usage for the proposed and base case. The calculation uses bin temperature data adjusted for the months when school is in session to account for only the hours when the cooling system is in regular use. U pgrading the existing EER 11 units with EER 17.6 condensing units would result in an electricity savings of 1,630 kwh annually. New Jersey BPU - Energy Audits Page 13 of 33

See section 5.0 for other incentive opportunities. This measure is not recommended. 4.8 ECM-8 Lighting Replacement / Upgrades The classrooms and other occupied spaces have upgraded to electronic ballasts and utilize mainly 4 foot 2 lamp 32W T-8 fluorescent bulbs, U-tube T-8s, and 2 foot T-8s are also used in some fixtures. Biaxial compact fluorescent lights (CFLs) are utilized in can lights and surface mounted standard bulb fixtures to replace original incandescent bulbs. A fluorescent lamp converts electrical power into useful light more efficiently than an incandescent lamp or T-12 bulbs. A comprehensive fixture survey was conducted of the entire building. E ach 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 by upgrading the classrooms to super T-8 fixtures, and the exterior metal halides to LED fixtures. Energy savings for this measure were calculated by applying the existing and proposed fixture wattages to estimated times of operation. T he difference between energy requirements resulted in a t otal annual savings of 26,070 kwh with an electrical demand reduction of about 8.7 kw. 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-8 Upgrade Current Lighting Fixtures Budgetary Estimated Total Payback Payback Cost Annual Utility Savings Maintenance Savings ROI Incentive * (without (with Electric Electric Nat Gas Total Savings incentive) incentive) $ kwh kw Therms $ $ $ $ Years Years 54,000 26, $ 4, , , Expected Life: 15 years Lifetime Savings: 391,100 kwh 0 therms $ 64,500 *Incentive shown is per the New Jersey Smart Start Program. See section 5.0 for other incentive opportunities. This measure is not recommended in lieu of ECM-10. New Jersey BPU - Energy Audits Page 14 of 33

16 4.9 ECM-9 Lighting Controls Installation The current lighting is controlled by manual switches. Lights are generally turned on in the morning and shut off at night. During school hours, there are rooms that are not occupied; however, the lights sometimes remain on. A dding occupancy controls to individual rooms will control the lights based on occupancy. The occupancy sensor can be wall mounted near the switch or placed at the ceiling for larger room coverage. All occupancy sensors are equipped with a manual override feature. These sensors are generally not recommended in public restrooms. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM-9 Install Occupancy Sensors Budgetary Estimated Total Payback Payback Cost Annual Utility Savings Maintenance Savings ROI Incentive * (without (with Electric Electric Nat Gas Total Savings incentive) incentive) $ kwh kw Therms $ $ $ $ Years Years 6,000 42, , , , Expected Life: 15 years Lifetime Savings: 641,300 kwh 0 therms $ 87,000 * Incentive shown is per the New Jersey Smart Start Program.

17 4.11 System Improvement Opportunities The following item can be implemented by the owner to provide additional energy savings: It is recommended that vending misers be added to all district owned vending machines. It is also recommended the school requests that vendor owned machines be upgraded or removed if they are not high efficiency equipment. New Jersey BPU - Energy Audits Page 16 of 33

18 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. T he 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 m onths exceeds 100 kw. T his 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 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 d etermined 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: 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 New Jersey BPU - Energy Audits Page 17 of 33

19 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 Incentives #2 and #3 can be combined to yield additive savings. Total P4P incentives are summarized below: Incentives $ Electric Gas Total Incentive #1 $0 $0 $5,000 Incentive #2 $7,357 $8,806 $16,163 Incentive #3 $7,357 $8,806 $16,163 Total $14,714 $17,612 $37,326 The current ECM s meet the minimum savings of 15% and therefore the building would be eligible for incentives #2 and #3. See Appendix D for additional details New Jersey Smart Start Program For this program, specific incentives for energy conservation measures are calculated on an individual basis utilizing the 2012 New Jersey Smart Start incentive program. T his program provides incentives dependent upon mechanical and electrical equipment. I f applicable, incentives from this program are reflected in the ECM summaries and attached appendices. If the complex 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 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 or natural gas utility companies. On a case-by-case 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, natural gas, refrigeration, and other equipment upgrades with higher efficiency alternatives. I f 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. I nstallations must be completed by a Direct Install participating contractor, a list of which can be found on t he 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. New Jersey BPU - Energy Audits Page 18 of 33

20 The facility is eligible to receive funding from the Direct Install Program due to its low peak electric demand 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. L ocal units should carefully consider all alternatives to develop an approach that best meets their needs. New Jersey BPU - Energy Audits Page 19 of 33

21 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. T he building s roof has sufficient room to install a l arge solar cell array. A ll rooftop areas have been replaced, and are in good condition. 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. The PVWATT solar power generation model is provided in Appendix F. Federal tax credits are also available for renewable energy projects up to 30% of installation cost. Since the facility is a non-profit organization, federal taxes are paid and this project is 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). T his 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. One SREC credit is equivalent to 1,000 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 $80/ 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 100 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, for a 100 kw 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 F and summarized as follows: Photovoltaic (PV) Rooftop Solar Power Generation 100 kw System New Jersey Budgetary Annual Utility Savings Total Federal Renewable Payback Payback Cost Savings Tax Credit * SREC** (without incentive) (with incentives) Natural Electricity Gas Total $ kw kwh Therms $ $ $ $ Years Years $400, ,897 0 $20,382 $20,382 $0 $9, * 30% federal tax credit-not available for schools ** Solar Renewable Energy Certificate Program (SREC) for 2012 is $80/1000kwh New Jersey BPU - Energy Audits Page 20 of 33

22 The existing roof would need a structural analysis to ensure that it can support the additional weight of the panels. Installing a photovoltaic system is recommended if SREC credits can be secured to offset the high installation cost of the system. At the current SREC rate, this measure is not recommended 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. D HW is presently produced by gas-fired water heaters and, therefore, this measure would offer natural gas utility savings. Currently, an incentive is not available for installation of thermal solar systems; a Federal tax credit of 30% of installation cost for the thermal applications is available. This is not recommended since the facility currently uses natural gas, the building is not occupied year-round, and domestic hot water demand is not excessive. The implementation cost and savings related to this ECM are presented in Appendix F and summarized as follows: Budgetary Annual Utility Savings Total Federal Tax Credit Cost Savings * Electricity Natural Gas Total Payback (without incentive) Payback (with incentives) $ kw kwh Therms $ $ $ Years Years $5, ,220 $130 $130 1,500 >25 >25 This measure is not recommended. 6.2 Demand Response Curtailment Presently, electricity is delivered by South Jersey Energy Company, which receives the electricity from PSE&G. South Jersey Energy Company is a regional transmission organization (RTO) that coordinates the movement of wholesale electricity in all or parts of 13 states and the District of Columbia including the State of New Jersey. New Jersey BPU - Energy Audits Page 21 of 33

23 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. P art 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 October 2010 through September 2011, the Englewood Cliffs North Cliffs Elementary School had a maximum electricity demand of 90.6 kw and a minimum of 16.8 kw. The monthly average over the observed 12 month period was 45.1 kw. This measure is not recommended because the facility does not meet the minimum required load, is not operating year round, and does not have back up/emergency generator power.

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 S ite 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 ECMs, 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). S ite EUI is a m easure of a building s annual energy utilization per square foot. Site EUI is a good measure of a building s energy use and is utilized regularly for comparison of energy performance for similar building types. Site Energy Intensity = (Electric Usage in kbtu + Natural Gas in kbtu) Building Square Footage To provide an equitable comparison for different buildings with varying proportions of primary and secondary energy consumption, the Portfolio Manager uses the convention of Source EUIs. The source energy also accounts for all losses incurred in production, storage, transmission, and delivery of energy to the site; which provides an equivalent measure for various types of buildings with different energy sources. Source Energy Intensity = (Electric Usage in kbtu X Site/Source Ratio + Natural Gas in kbtu X Site/Source Ratio) Building Square Footage The EPA Score, Site EUI, and Source EUI for Englewood Cliffs North Cliffs Elementary School are as follows: Energy Intensity Englewood Cliffs North Cliffs Elementary School National Average EPA Score Site (kbtu/sf/year) Source (kbtu/sf/year) The North Cliffs Elementary School is considered a lower than average energy consumer by the EPA Portfolio Manager which gives it a higher than average EPA score. F or the North Cliffs Elementary School to qualify for the Energy Star label the EPA score is required to be above 75. There are several energy conservation measures recommended in this report, that if implemented will further reduce the energy use intensity and increase the EPA score of the school.

The Notice covers a model ESCO (Energy Services Company) Request for Proposal document and provides information on using the Do-It-Yourself process for implementing an ESIP. This Notice supplements Local Finance Notice concerning ESIPs. Model ESCO Request for Proposal Document General Issues The Division of Local Government Services and the Board of Public Utilities have completed development of a model ESCO Request for Proposal Document. It is designed to assist all organizations (contracting units) covered by the LPCL and PSCL hire an energy services company (ESCO) to develop and implement an Energy Savings Plan (ESP) as part of an Energy Savings Improvement Program as authorized under N.J.S.A. 40A: and 18A:18A-4.6. Specifically, the document serves as the starting point for these government agencies to select an ESCO through the competitive contracting procedure (N.J.S.A. 40A: et seq. and 18A:18A-4.1 et seq.). Notwithstanding the efforts of the State agencies to ensure that the RFP is consistent with all relevant procurement procedures, laws, and regulations, there are several issues contracting unit personnel should keep in mind: 1) Local legal advisors should review the document to ensure it is consistent with any allowable local practices and legal considerations. 2) The individual responsible for managing the project should review the entire RFP in order to be able to answer questions and ensure the document meets local needs. 3) Forms have been carefully designed to meet the need of this specific process. Care should be taken if proposed forms are removed and replaced with ones normally used by the contracting unit.

58 Local Finance Notice June 16, 2011 Page 2 Feedback from users about the model is encouraged and the Division plans to update it as experience warrants. To start this feedback process two immediate options are available to users. 1. An ESIP webpage has been established for ESIP issues (the model document will be posted there as well) and it has the ability for users to comments directly to the Division. 2. The Division will hold a meeting to accept comments from interested parties on the RFP. The meeting is scheduled for Thursday, July 28, 2011 at 9:30, to take place at DCA offices at 101 South Broad Street in Trenton. Attendees are asked to register (via ) if they plan to attend or speak; if too many people sign up, we may move the location and will need to contact attendees. This is not an educational session there will be no staff presentations on the RFP and is expressly to take comments that are not submitted in writing. It is expected that professional organizations will sponsor training sessions this fall. As changes are made, they will be noted in text or in a tracked document and posted to the website. Users are urged to check the site to be sure they are using the latest version. The GovConnect Local Procurement role will be used to notify procurement officials when a new version has been posted. Using the Model ESCO RFP The Model ESCO RFP is broken into several self-explanatory sections: Part A. Instructions to Proposers Part B. Terms and Conditions Part C. Scope of Work Part D. Proposal Evaluation Part E. Form of Proposal and Content Part F. Appendix Part G. Proposal Forms It is designed to be used by contracting units under the LPCL and PSCL, but it requires the user to edit the document to reflect the specific type of contracting unit. These edits are substantive and reference-related edits, and are listed below. The RFP is designed to minimize the amount of drafting of technical issues related to an ESIP effort. Since development of an Energy Savings Plan (ESP) is based on an audit that meets the statutory requirements previously conducted by the contracting unit, it is the responsibility of the contracting unit to provide proposers with a copy of the audit as part of the ESCO RFP package (or linked to an online posting of the audit). The audit should guide contracting units to make preliminary decisions concerning energy conservation measures to include in their ESIP. To inform proposers of these decisions, Appendix A of the RFP must be completed by the contracting unit to inform proposers of the projects to be undertaken and any special considerations that proposers are to incorporate into their proposal.

59 Local Finance Notice June 16, 2011 Page 3 The RFP also uses a formal process for potential proposers to submit questions and requests for clarifications. Appendix B is a form for the submission of these requests and is referred to throughout the text. Contracting units are also reminded the Competitive Contracting process does not allow for negotiating proposals. While legal elements of the contract (project development agreement) may require legal determinations and modifications, the process does not allow for negotiation of price or related substantive elements and any element that would have provided less than a level playing field for proposers. Contracting units are also cautioned that setting qualification standards that arbitrarily limit competition is inconsistent with public bidding requirements. Office of State Comptroller Filing: Contracting units are also reminded of their obligations to meet State Comptroller requirements for public contracts. In accordance with N.J.S.A 52:15C- 10, contracting units must notify OSC as early as practicable, but no later than 30 days before advertisement, of any negotiation or solicitation of a contract that may exceed $10 million. Contracting units must also provide post-award notification for any contract for an amount exceeding $2 million. Notification must be given within 20 days of the award. Substantive Edits: Several sections are highlighted in green. These sections should be carefully edited to meet contracting unit needs. This has important application to evaluation criteria in Section D. Once finalized, the green highlight should be removed. Section B-16; Insurance should be reviewed by the contracting unit s Risk Management professionals to be sure the standards are appropriate to the contracting unit and the work to be done. The following Sections also require local decisions and editing: A-3: # of copies of proposal and # of CDs to be submitted A-4: Web posting address, if desired A-5: If extra credit is to be provided on evaluation scoring for attending site walk through B-11: Delete LPCL or PSCL section as appropriate B-34: Use only if PSCL C-1: Explanation of type of audit information C-3(k): Include if ESCO is to provide financing option Use of Appendix F and Proposal Requirements #8: These forms are related to submission of Political Contribution Disclosure forms. Only PSCL agencies are required to use these forms as pursuant to Public School Fiscal Accountability Procedures (N.J.A.C. 6A23A- 6.3). The forms and references to it should be removed for all LPCL users.

60 Local Finance Notice June 16, 2011 Page 4 Reference Editing: <Brackets> are used to highlight text that requires user editing. Users need to review each set and edit as necessary to properly reflect the contracting unit s circumstances. For example, brackets are used to reflect statutory references (i.e., LPCL or PSCL listings), the name of owner, or refer to a website. It is urged that preparers use the search function to locate brackets to be sure all references are corrected. Header: the header section should be edited to reflect the name of the contracting unit Footer: The footer includes a reference to the version of the RFP document. It is recommended that the reference be removed when the RFP is circulated. The model includes a draft Cover letter to send to potential proposers. Located immediately following the cover page, it should be removed and used as a separate document, not part of the RFP. Consider how to refer to the owner s full name or where owner is used. The ESIP Alternative to ESCO: the Do-it-Yourself Process The ESIP law (see Local Finance Notice ) allows two approaches to taking advantage of the financing options the law provides. It allows development and implementation using an ESCO and permits a Do-It-Yourself (DIY) option. The DIY approach involves the contracting unit properly procuring services from different organizations to perform the various elements of an ESIP (i.e., audit, ESP preparation, developing construction plans and specification, etc.). It is an alternative to the ESCO approach, where a single organization provides a wide range of services. Under both contracting models, it is important that contractors performing a range of services do not have conflicts (e.g., the firm developing plans and specifications cannot conduct the final system verification, or the firm that conducts the audit cannot serve as an ESCO). The DIY approach allows the contracting unit to contract for an energy audit from a NJ Division of Property Management and Construction (DPMC) approved energy auditor. At the conclusion of the audit, the contracting unit can choose to specify energy conservation measures (ECM s) in its ESP than can be implemented through a DYI process. The process (ESCO or DIY) also requires that an independent organization verify the ESP. Once the governing body approves the ESP, the contracting unit can then hire (subject to procurement law) a DPMC approved professional architect or engineering firm to design the improvements and prepare the plans and specifications for implementing the Energy Savings Plan. In these cases, subject to the contracting unit procurement requirements, the firm conducting the audit and preparing the ESP, if DPMC qualified, may also provide the services necessary to develop plans and specifications for the contracting unit to use for bidding purposes, as long as they provide the contracting unit Errors and Omissions insurance coverage.

61 Local Finance Notice June 16, 2011 Page 5 Under the ESIP DIY approach, there would be no conflict in a properly procured single organization conducting the audit, developing the ESP, then preparing plans and specifications. This does not apply when using the ESCO approach, where the auditor and ESCO must be independent. Once construction plans and specifications are complete, the contracting unit would then conduct the bidding process as it would any public works construction project: manage the project as it sees fit (the firm that did the plans could also serve as construction manager), and then contract as necessary for commissioning and final third party verification. The two verification steps (the ESP and verifying implementation) must be performed by an organization independent of the ones preparing the ESP, overseeing construction and commissioning. By following this process, the contracting unit can then apply to the Local Finance Board for the issuance of ESIP-based energy saving obligations or enter into appropriate lease financing. The ESIP approach to energy improvement provides a range of options for contracting units to accrue energy savings while improving the environment, taking advantage of low-cost financing and state and federal incentives. DLGS and the BPU encourage comments and questions (through the ESIP web page) on this new opportunity so we can improve it as time goes on. Approved: Thomas H.
