6 2.0 EXECUTIVE SUMMARY This report details the results of the Roxbury library, located in Roxbury, New Jersey. The single story, approximately 13,600 square foot building houses about 82,000 public reference items. The following areas were evaluated for energy conservation measures: Lighting replacement with occupancy sensors Door seals Energy Management Control System Condensing boiler Restroom/kitchen fixture upgrades Domestic hot water heater Boiler outdoor air reset Rooftop unit replacement Various potential Energy Conservation Measures (ECMs) were identified for the above categories. Measures which are recommended for implementation have a payback of 10 years or less. This threshold is considered a viable return on investment. Potential annual savings of $31,100 for the recommended ECMs may be realized with a payback of 4.2 years. The ECMs identified in this report will allow for the building to reduce its energy usage and if pursued has the opportunity to qualify for the New Jersey SmartStart Buildings Program.

8 3.0 EXISTING CONDITIONS 3.1 Building General Structure The library is a 13,600 square foot building constructed in 1974, which has expanded twice. The first addition in 1983 provided supplemental space for adult and children s materials. The second addition, completed in 1993, provided quiet study space, increased seating, expanded Reference Department, improved check-out area, computer resources center, periodical reading room, and small meeting room. In addition, the exterior of the building was modified to reflect the aesthetics of other buildings in the Main Street Historic District. The exterior is composed of face brick and concrete with some glass walls built on a concrete foundation. The interior walls are constructed of concrete masonry unit (CMU), or metal studs and gypsum board. The windows and doors are single pane glass with metal frames. The building has two main entrances, one for the front of the building; the other for the rear parking lot. The roof system is flat, ballasted, with a rubber membrane. According to township personnel, the roof is leaking in four or five locations. The roof is scheduled to be replaced due to age Operating Hours The library is open from 9:30 AM 9:00 PM Monday through Thursday, 9:30 AM 5:00 PM Fridays, 9:30 AM 3:00 PM Saturdays, and 2:00 PM 5:00 PM Sundays. The custodian typically arrives at 6:30 AM Monday through Friday. 3.2 Utility Usage The library uses electricity, natural gas, municipal water, and is connected into the municipal sewage system. Electricity is purchased and delivered by Jersey Central Power & Light (JCP&L), and natural gas purchased and delivered by New Jersey Natural Gas (NJNG). For 2008, the building had an annual electrical consumption of 290,000 kwh at a cost of $47,200, natural gas usage of 11,740 therms at a cost of $18,400, and water usage of 126,400 gallons at a cost of $800. The total utility bill for 2008 was $66,400. The largest portion of energy usage is for electricity and the average blended rate was $0.163 per kwh. The electrical usage trend shows higher consumption during the summer cooling months. The majority of natural gas is used for building heating as indicative of the higher usage trend during the colder months of November through April. The average rate for natural gas was $1.57 per therm. The average rate for water usage was $6.22 per 1000 gallons. Utility data is provided in Appendix A. New Jersey BPU - Energy Audits Page 4 of 26

9 3.3 HVAC Systems Central System The current HVAC system is comprised of six rooftop units (RTUs). Two are direct expansion cooling/electric heating rooftop units (RTU Nos. 3 and 6), and four are direct expansion cooling/hot water coil heating rooftop units (RTU Nos. 1, 2, 4 and 5) supplied with hot water from the natural gas fired boiler. RTU-1 has a variable air volume (VAV) distribution system; all other RTUs supply air directly to the spaces they serve. RTU No. 2 is a Carrier unit which serves the meeting room and surrounding office areas. Rust is visible on the unit, which is assumed to be over 20 years old. This unit is nearing its useful life expectancy and should be replaced. The remaining five RTUs are manufactured by Lennox and between one and six years old. The Lennox units have not experienced any operational issues. Three direct expansion (DX) ductless split systems provide air conditioning to the small rooms adjacent to the main entrance and file room. The periodical area has a small amount of electric baseboard heating. See Appendix B for an Equipment Inventory Hot Water Heating Systems The library is primarily heated by hot water produced by a natural gas fired boiler and circulated through a piping system to perimeter fintube radiation. The boiler is rated at 1,600 MBH input and is estimated to be 65% efficient based on its age. Based on discussions with library staff, the boiler is approximately 20 years old and has undergone several recent repairs, including section replacement Controls The building does not have a functional direct digital control (DDC) system to monitor the heating, air conditioning, and ventilating systems. The current DDC system for the boiler failed in 2009 and was removed from service. Wall mounted thermostats control the space temperature provided by most HVAC rooftop units. The exception is RTU-1 which uses a wall mounted VAV controller that, in conjunction with space temperature sensors, satisfies heating and cooling requirements to the book stack area. A new DDC system would provide the building with a central user interface used to schedule the HVAC equipment to turn off or provide temperature setback during unoccupied hours. 3.4 Lighting/Electrical Systems The interior lighting within the building is comprised of mainly inefficient T-12 fluorescent light fixtures with a few compact fluorescent light (CFL) screw-type bulb fixtures. Lighting is controlled by either individual switches or by breakers located on two separate main control panels. In most cases, the lighting on breakers is turned on and off by the custodian and staff. The lighting remains on depending on occupancy, generally about 10 hours a day. The exit signs are all energy efficient LED type wired individually to breakers. The building s parking lot and exterior building lighting consists of a mixture of metal halide and mercury vapor fixtures that utilize bulbs ranging from 55 to 400 watts. There are also compact fluorescent lights outside the front building entrance. The exterior lighting is controlled by a timer. New Jersey BPU - Energy Audits Page 5 of 26

10 There are several lights within a maintenance shed next to the library that are not used frequently. These lights consist of one 8 T-12 and one 4 T-8 fluorescent fixtures. 3.5 Plumbing Systems Hot water is produced by one A.O. Smith electric hot water tank located in the boiler room. The tank has a capacity of 50 gallons and utilizes 4.5 kw of electricity when both elements are energized. The unit was installed in The plumbing system consists of domestic water, sanitary, and vent piping. Plumbing fixtures include urinals, toilets, sinks, and floor drains.

11 4.0 ENERGY CONSERVATION MEASURES 4.1 ECM-1 Lighting Replacements A comprehensive fixture survey was conducted of the entire building. Each switch and circuit were identified, and the number of fixtures, locations, and existing wattage established. Most of the lighting consists of T-12 fluorescent fixtures with inefficient T-12 lamps. Each fixture is equipped with two 2 utube bulbs, two 4 straight bulbs, or four 4 straight bulbs. Overall energy consumption can be reduced by retrofitting the approximately 325 T-12 fixtures with more efficient T-8 fluorescent lamps. Existing T-12 lamps and ballasts of each fixture can be replaced with electronic ballasts and two or four 4, T-8 fluorescent lamps as required. This measure will allow the facility to stock only T-8 fixtures in the future. Presently, the facility has a mixture of T-12 lamps with multiple ballast combinations. In the future, the facility should only purchase low wattage super T-8s and ballasts such as the low wattage 4-foot 28 watt units. These lamps may be directly installed into any existing 34 watt fixture when lamps fail. By installing these lamps over time, the most efficient lighting system available will be consistent throughout the facility. This measure also considers replacing the building s exterior wallpack lights (consisting of 250 watt high pressure sodium lamps) and parking lot pole fixtures (consisting of 400 watt metal halide lamps) with new high efficient induction lighting technology. Induction lamps incorporate a fluorescent lamp without electrodes, where magnetic induction is used to ignite the phosphors rather than electrodes. Typically, a 250 watt induction lamp can be compared to a new 400 watt metal halide lamp from a light output standpoint, and have the added benefit of being rated at up to 100,000 hours. The lighting replacements have an expected life of 15 years, according to the manufacturer, and total energy savings over the life of the project are estimated at 613,500 kwh and $105,000. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM-1 Lighting Replacements Budgetary Annual Utility Savings Potential Payback Payback Cost Incentive* (without incentive) (with incentive) Electricity Natural gas Total ROI $ kw kwh Therms $ $ Years Years 45, , , , *Incentive is based on the New Jersey Smart Start Prescriptive Lighting Measures. This measure is recommended when combined with ECM-2; see ECM ECM-2 Install Occupancy Sensors It is proposed that occupancy sensors be installed in selected rooms to turn off lights when the area is unoccupied. A lighting survey was conducted of all fixtures to determine the average time lights are presently on in each space. Occupancy sensors were not considered for the general library areas as well as mechanical or utility rooms due to safety concerns. Other areas were not considered due to the proposed location of occupancy sensors. If a sensor does not have a clear view of the area, it may darken even with people in the space, creating an unsafe condition. New Jersey BPU - Energy Audits Page 7 of 26

12 Lighting fixtures are manually switched on and off at switches or breakers at main control panels. The lights are operational from opening to closing of the building based on occupancy. Each interior building light is operated approximately 65 hours per week. Typical traffic patterns for each space were then taken into account to approximate the actual occupancy hours per day. Approximately nine occupancy sensors and minor standard electrical work are required for this measure. Occupancy sensors are recommended for the offices, kitchen/breakroom, meeting room, and periodical storage. Lighting controls have an expected life of 15 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 48,000 kwh, and $7,500. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM-2 Install Occupancy Sensors Budgetary Annual Utility Savings Potential Payback Payback Cost Incentive* (without incentive) (with incentive) Electricity Natural gas Total ROI $ kw kwh Therms $ $ Years Years 1, , *Incentive is based on the New Jersey Smart Start Prescriptive Lighting Measures. This measure is recommended when combined with ECM-1; see ECM ECM-3 Lighting Replacements with Occupancy Sensors This measure is a combination of ECMs 1 and 2 to allow for maximum energy and demand reduction. Due to interactive effects, the energy and cost savings for occupancy sensors and lighting upgrades are not cumulative. The lighting retrofits and controls have an expected lifetime of 15 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 643,500 kwh, and $108,000. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below: ECM-3 Lighting Replacements with Occupancy Sensors Budgetary Annual Utility Savings Potential Payback Payback Cost Incentive* (without incentive) (with incentive) Electricity Natural gas Total ROI $ kw kwh Therms $ $ Years Years 46, , , , *Incentive is based on the New Jersey Smart Start Prescriptive Lighting Measures. This measure is recommended. New Jersey BPU - Energy Audits Page 8 of 26

13 4.4 ECM-4 Install Door Seals The doors are original to the building s construction and the gaps around the perimeters result in air infiltration. Installing door seals will reduce infiltration and save energy. This measure determined the perimeter length and gap spacing of the doors. Infiltration reductions and associated energy savings were then calculated by using weather bin heating and cooling hour data. Door seals have an expected life of 10 years, according to the manufacturer, and total energy savings over the life of the project are estimated at 1,700 kwh, 7,000 therms and $11,000. The implementation cost and savings related to this ECM are presented in Appendix D and summarized below: ECM-4 Install Door Seals Budgetary Annual Utility Savings Potential Payback Payback Cost Incentive* (without incentive) (with incentive) Electricity Natural gas Total ROI $ kw kwh Therms $ $ Years Years 1, , NA * There is no incentive available through the New Jersey Smart Start program for this ECM. This measure is recommended. 4.5 ECM-5 Night Setback Controls The building s HVAC systems are comprised of a mixture of programmable thermostats and temperature sensors for controlling space temperature. Temperature setback is not fully utilized. This measure proposes that a DDC system be installed in conjunction with the existing 13 thermostats and temperature sensors. It was assumed that four thermostats or temperature sensors of the 13 existing units will need to be replaced due to age or the inability to be connected to the proposed DDC system. The DDC system will be programmed for night setback of heating and cooling space temperatures. Temperatures could, therefore, be controlled and programmed from a central computer. As part of this measure, all air cooled condensers should be cleaned to reduce the operating head pressure of the compressors, thereby improving system efficiency. It should be noted that the Township of Roxbury could achieve similar energy savings without installation of a centralized DDC if the existing thermostats were programmed for a night setback of 80 F for unoccupied summer cooling, and 60 F for unoccupied winter heating. The thermostats would need to be secured such that occupants could not change the programmed night setback. Night setback has an expected lifetime of 15 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 244,500 kwh, 27,000 therms and $82,500.

14 The implementation cost and savings related to this ECM are presented in Appendix E and summarized below: ECM-5 Night Setback Controls Budgetary Annual Utility Savings Potential Payback Payback Cost Incentive* (without incentive) (with incentive) Electricity Natural Gas Total ROI $ kw kwh Therms $ $ Years Years 14, ,300 1,800 5, NA * There is no incentive available through the New Jersey Smart Start program for this ECM. This measure is not recommended in lieu of ECM ECM-6 Night Shutdown The building s HVAC systems have programmable thermostats for controlling space temperature; however, presently system set back or shut down is not utilized when not occupied. This measure proposes that the DDC control system be installed in conjunction with new thermostats to be programmed for night shutdown. This measure calculates energy savings based on shutting down electric components such as exhaust fans and compressors. It should be noted that the Township of Roxbury could achieve similar energy savings without installation of a centralized DDC. Local controls or timeclocks could achieve the same effect at lower cost. Night shutdown has an expected life of 15 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 736,500 kwh and $120,000. The implementation cost and savings related to this ECM are presented in Appendix F and summarized below: ECM-6 Night Shutdown Budgetary Annual Utility Savings Potential Payback Payback Cost Incentive* (without incentive) (with incentive) Electricity Natural Gas Total ROI $ kw kwh Therms $ $ Years Years 10, , , NA * There is no incentive available through the New Jersey Smart Start program for this ECM. This measure is not recommended in lieu of ECM ECM-7 Enthalpy Economizer Heat internal to the building such as people, lights, computers, copy machines, motors, and other machines causes the temperature inside to increase. This energy conservation measure considers turning off the packaged rooftop units compressors and using cool outside air to satisfy the cooling needs of the building when outside temperature makes this option feasible. An economizer with enthalpy control that measures the outdoor temperature and humidity is proposed for this measure. The enthalpy control would measure both sensible and latent heat in the air and allow outside air to be used for cooling if sufficiently cool and dry to satisfy the space conditions. This condition has been calculated to occur approximately New Jersey BPU - Energy Audits Page 10 of 26

15 from 47 to 60 of outdoor air temperature. If the indoor thermostat calls for cooling and the outside air enthalpy is sufficiently low, the economizer would bring in the cooler and less humid air and use it for cooling. Using outside air for cooling is less costly than operating the compressor to provide cooling. It should be noted that the Township of Roxbury could achieve similar energy savings without installation of a centralized DDC. Local controls could achieve the same effect at a lower cost. Enthalpy economizers have an expected life of 15 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 136,500 kwh and $22,500. The implementation cost and savings related to this ECM are presented in Appendix G and summarized as follows: ECM-7 Enthalpy Economizer Budgetary Annual Utility Savings Potential Payback Payback Cost Incentive* (without incentive) (with incentive) Electricity Natural Gas Total ROI $ kw kwh Therms $ $ Years Years 7, , , NA * There is no incentive available through the New Jersey Smart Start program for this ECM. This measure is not recommended in lieu of ECM ECM-8 Install Demand Control Ventilation An energy savings option would be to utilize demand control ventilation (DCV), which measures carbon dioxide (CO 2 ) in the return air stream to an air handler and adjusts the outside air ventilation to maintain a CO 2 specified setpoint. An increase in CO 2 is representative of an increase in the number of occupants in a space. Outside air dampers would modulate and allow only the required amount of outside ventilation needed to match room occupancy. By controlling the ventilation based on occupancy, savings of natural gas and electricity can be achieved. To determine savings, the energy required for full constant outside air ventilation was compared to the energy needed for variable ventilation based on room occupancy. The outside air CFM rates are based on equipment information and code requirements for outside air ventilation. Hourly weather bin data for heating and cooling periods and current room temperature setpoints were used to determine savings. Installing DCV would require CO 2 sensors, upgrades to the outside air damper actuators, control system programming, and electrical wiring modifications. Demand control ventilation has an expected life of 15 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 30,660 kwh and $35,900.

16 The implementation cost and savings related to this ECM are presented in Appendix H and summarized below: ECM-8 Install Demand Control Ventilation Budgetary Annual Utility Savings Potential Payback Payback Cost Incentive* (without incentive) (with incentive) Electricity Natural Gas Total ROI $ kw kwh Therms $ $ Years Years 6, , *Incentive is based on the New Jersey Smart Start Prescriptive Electric Unitary HVAC Measures. This measure is not recommended in lieu of ECM ECM-9 Energy Management Control System This measure combines ECM-5, 6, 7, and 8 into an integrated control system by installing a DDC system to control space temperature from a single location. Implementing these measures would result in savings since less energy will be required to heat and cool the outside air. Utilizing a DDC system will also provide occupant comfort. The DDC system has an expected life of 15 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 1,128,000 kwh, 34,500 therms and $237,000. The implementation cost and savings related to this ECM are presented in Appendix I and summarized below: ECM-9 Energy Management Control System Budgetary Annual Utility Savings Potential Payback Payback Cost Incentive* (without incentive) (with incentive) Electricity Natural Gas Total ROI $ kw kwh Therms $ $ Years Years 29, ,200 2,300 15, , *Incentive is based on the New Jersey Smart Start Electric Unitary HVAC Measures. This measure is recommended ECM-10 Boiler Outdoor Air Reset on Existing Boiler This measure proposes to install an outdoor air reset on the existing boiler, which would control space temperature from a single location. Reset control is an electronic energy management system that balances boiler water temperature with the outdoor temperature. By constantly measuring outside temperature, the system determines the optimum hot water loop temperatures needed to heat the building at the optimal boiler efficiency. Reset control requires an outdoor air sensor on the north side of the building and a sensor mounted at the boiler loop to sense water temperature. The equipment has an expected life of 15 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 1,500 therms and $2,250.

This measure is not recommended ECM-11 Condensing Boiler Installation The library utilizes a hot water boiler to heat the building. The boiler has undergone extensive repairs including section replacement, according to library staff, and is nearing its useful life expectancy. It is approximately 65% efficient. More efficient units, such as condensing boilers, provide efficiencies of 93%. The energy saved is determined by comparing the difference in the energy used by the existing boiler and proposed condensing boiler for hot water heating. Condensing boilers work on the principle of recovering as much waste heat as possible, which is normally ejected into the atmosphere from the flue of a conventional (non-condensing) boiler. This design maximizes the heat transfer from the burner and recovers useful heat which would normally be lost with the flue gases. When in condensing mode, (condensing boilers do not condense continually) the flue gases give up latent heat which is then recovered by the heat exchanger within the boiler. As a result, the temperature of the gases exiting the flue of a condensing boiler is typically F. This measure proposes replacing the existing boiler with two new 750 MBH condensing boilers in the same boiler room area. Modifications to the existing piping, electrical wiring, and flue stacks would also be required. The condensing boiler has an expected life of 20 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 70,000 therms and $112,000. The implementation cost and savings related to this ECM are presented in Appendix K and summarized below: ECM-11 Condensing Boiler Installation Budgetary Annual Utility Savings Potential Payback Payback Cost Incentive* (without incentive) (with incentive) Electricity Natural Gas Total ROI $ kw kwh Therms $ $ Years Years 45, ,500 5, , *Incentive is based on the New Jersey Smart Start Gas Heating Measures. This measure is recommended. New Jersey BPU - Energy Audits Page 13 of 26

18 4.12 ECM-12 Replace Domestic Hot Water Heater Currently, domestic hot water is produced utilizing an electric hot water heater and storage tank, with a 4.5 kw heating element immersed in a 50 gallon storage tank. The unit is installed in the boiler room. This measure proposes installing a condensing natural gas fired domestic hot water heater. Condensing efficiency of up to 94% is achieved by adding more heating surface than other water heaters while maintaining the same Btu input. Due to the extra heating surface, flue gases in the water heater are cooled to the point where moisture in the flue gases can no longer remain as vapor and condenses on the heating surfaces inside the water heater. This change releases energy through the heating surface into the stored water helping to raise water temperature. The heater s ability to capture the energy created by the vapor-to-liquid change results in higher thermal efficiencies. This energy is wasted out of the flue in other gas or oil fired water heaters. Condensate collects at the base of the unit and is evacuated from the appliance. Natural gas as well as flue gas modifications would be required for this upgrade. Condensing natural gas fired domestic hot water boiler has an expected life of 20 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 110,000 kwh, additional gas usage equivalent to (2,500) therms for a net total savings of $14,000. The implementation cost and savings related to this ECM are presented in Appendix L and summarized below: ECM-12 Replace Domestic Hot Water Heater Budgetary Annual Utility Savings Potential Payback Payback Cost Incentive* (without incentive) (with incentive) Electricity Natural Gas Total ROI $ kw kwh Therms $ $ Years Years 5, ,500 (125) *Incentive is based on the New Jersey Smart Start Gas Water Heating Measures. This measure is recommended ECM-13 Rooftop Unit Replacement The existing rooftop unit is over 20 years old and nearing its useful life expectancy, and the efficiency has decreased. This measure proposes to replace the existing 7.5 ton RTU #2 with a new higher efficiency unit. The average energy efficiency ratio (EER) of the existing unit is approximately 7.0 EER; the proposed unit is approximately 11.5 EER. RTUs have an expected life of 20 years, according to ASHRAE, and total energy savings over the life of the project are estimated at 48,000 kwh and $8,000.

This measure is not recommended on energy savings alone, but due to the fact the unit needs to be replaced this energy savings can be realized ECM-14 Replace Urinal Flush Valves with Low Flow Types There is one urinal in the building, utilizing an inefficient flush valve, which would be replaced with a low flow model to conserve water usage. Usage was assumed to be 40 flushes per day. The existing urinal is rated for 3.0 gallons per flush (gpf) and has an estimated annual water usage of 44 thousand gallons (Kgal) per year. The proposed valve is rated for 1.0 gpf, therefore this measure would result in an annual water savings of about 29 Kgal per year. At a combined water and sewer charge of $6.32 per Kgal, this results in a cost savings of about $200 per year. Low flow urinal flush valves have an expected lifetime of about 20 years, and total estimated annual water and sewer savings over the life of the project are 580 Kgal and $3,800. The implementation cost and savings related to this ECM are presented in Appendix N and summarized below: ECM-14 Replace Urinal Flush Valves with Low Flow Types Budgetary Annual Utility Savings Estimated Potential Payback Payback Maintenance (without Cost Savings Incentive* incentive) (with incentive) Water / Sewer Total $ Kgal $ $ Years Years NA 3.0 NA * There is no incentive available through the New Jersey Smart Start program for this ECM. This measure is recommended ECM-15 Replace Toilet Flush Valves with Low Flow Types There are three toilets in the building with non-efficient flush valves, which would be replaced with low flow flush valves. By installing low flow valves, water usage would be reduced. For the calculation, 20 flushes per day per toilet. The existing toilets are rated for 3.5 gallons per flush and have an estimated annual water usage of approximately 77 Kgal per year. New Jersey BPU - Energy Audits Page 15 of 26

20 The proposed toilets are rated for 1.6 gallons per flush; therefore this measure would result in an annual water savings of about 42 Kgal per year. At a combined water and sewer charge of $6.32 per Kgal, this results in a cost savings of about $300 per year. Low flow flush valves have an expected lifetime of about 20 years, and total estimated annual water and sewer savings over the life of the project are 840 Kgal and $5,200.

21 5.0 POTENTIAL INCENTIVES 5.1 Incentives Overview The library energy conservation project may be eligible for incentives by the New Jersey Office of Clean Energy. The largest incentives available will be for the New Jersey Pay for Performance (P4P) Program. The P4P program is designed for qualified energy conservation projects in facilities that consume a minimum annual peak electric demand of 200 kw per month (building is eligible if the demand in any of the preceding 12 months exceeds 200kW). Facilities that meet this criterion must also achieve a minimum performance target of 15% by using an approved simulation modeling tool before and after construction. To utilize this program, a P4P Partner would need to be engaged. Incentives for the P4P program include the following: Incentive #1: The P4P Program pays $0.05 per square foot to a maximum of $50,000 or 50% of building annual energy cost for the P4P Partner to develop an Energy Reduction Plan (ERP). This incentive is paid after approval of the ERP and signed Installation Agreement. Applicant must agree to commit to implementation of the ERP within 6 months or the incentive must be returned to the state. Incentive #2: Paid after installation of recommended measures; base incentives deliver $0.11/kWh and $1.10/therm not to exceed 30% of total project cost. Incentive #3: Paid after acceptance of Post-Construction Benchmarking Report showing energy savings over one year utilizing the approved simulation modeling tool and EPA Portfolio Manager. Incentive #3 base incentives deliver $0.07/kWh and $0.70/therm not to exceed 20% of total project cost. Combining Incentives #2 and #3 will deliver a total of $0.18/ kwh and $1.80/therm not to exceed 50% of total project cost. Incentives for #2 and #3 are increased by $0.005/kWh and $0.05/therm for each percentage increase above the minimum performance target calculated with the approved simulation modeling tool, not to exceed 50% of total project cost. A new incentive structure has been announced for projects exceeding 20% in energy savings utilizing the required EPA portfolio manager benchmarking tool. The new incentive structure will double incentives #2 and #3 therefore producing a total of $0.36/kWh and a $3.60/ therm for those projects exceeding 20%. Incentive #1 for application preparation and energy reduction plan development has not changed however the maximum incentive has now been raised to 80% of project costs. The 200 kw/month minimum annual peak electric demand has been dropped so any structure can apply. This incentive structure will be in effect until December 31, Incentives are also available for prescriptive measures for various types of equipment under the New Jersey SmartStart Buildings incentive program. This program provides incentives dependent upon the existing equipment type and proposed equipment retrofit measure. Prescriptive measures under this program are paid after installation and no energy savings verification will be required. If applicable, incentives from this program are reflected in the ECM summaries and attached appendices. If the building qualifies and enters into the New Jersey P4P Program, all energy savings from recommended ECMs are included in the total building energy usage and savings to be applied towards the P4P incentive, including any ECMs that may have incentives available in the SmartStart Buildings program. A project is not applicable for incentives in both programs. New Jersey BPU - Energy Audits Page 17 of 26

22 5.2 Building Incentives New Jersey P4P Program The building is eligible for incentives under the New Jersey P4P Program. For the 13,600 square foot building, Incentive #1 corresponds to approximately $700. Since the overall energy reduction for the building is estimated to exceed the 15% minimum, the building is eligible for Incentives #2 and #3. When calculating the total Incentive #2 and #3 for the New Jersey P4P Program, all energy conservation measures are included as the amount received is based on building wide energy improvements. If all the energy conservation measures analyzed in this report are implemented, the total available incentive is up to $68,700 and would reduce payback from 5.5 to 2.5 years New Jersey SmartStart Buildings Program The building is also eligible for incentives under the New Jersey SmartStart Buildings Program for the ECM Nos. 3, 8, 9, 11, 12 and 13 analyzed in this study. The total amount of all qualified incentives is about $10,900. As mentioned previously, a project cannot apply for incentives from both the P4P Program and the SmartStart Buildings Program for the same project. See Appendix Q for calculations.

23 6.0 ALTERNATIVE ENERGY SCREENING EVALUATION 6.1 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. The building has an older boiler that serves the perimeter hot water fin tube radiation and (6) rooftop units with hot water coils. Cooling is also supplied by (3) ductless spit DX units. The periodical area has a small amount of electric baseboard heating. To take advantage of a GHP system, the building would have to install a low temperature closed loop water source heat pump system to realize the benefit of the consistent temperature of the ground. This will also include the removal of the existing heating and cooling system. This measure is not recommended due to the high cost to replace the existing HVAC systems. 6.2 Solar Photovoltaic Rooftop Solar Power Generation The building 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. A structural analysis would be required to determine if the roof framing could support a cell array. The PVWATTS solar power generation model was utilized to calculate PV power generation. The New Jersey Clean Power Estimator provided by the New Jersey Clean Energy Program is presently being updated; therefore, the site recommended use of the PVWAT solar grid analyzer version 1. The closest city available in the model is Newark, New Jersey and a fixed tilt array type was utilized to calculate energy production. The PVWAT solar power generation model is provided in Appendix R. The State of New Jersey incentives for non-residential PV applications is $1.00/watt up to 50 kw of installed PV array. Federal tax credits are also available for renewable energy projects up to 30% of installation cost. Municipalities do not pay federal taxes; therefore, would not be able to utilize the federal tax credit 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) solar-producers. An alternative compliance penalty (ACP) is paid for by the high emission New Jersey BPU - Energy Audits Page 19 of 26

24 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. The cost of the ACP penalty for 2009 is $689; this is the amount that must be paid per SERC by the high emission producers. The expected dollar amount that will be paid to the PV producer for 2009 is expected to be $600/SREC credit. Payments that will be received from the PV producer will change from year to year dependent upon supply and demand. Renewable Energy Consultants is a third party SREC broker that has been approved by the New Jersey Clean Energy Program. As stated above there is no definitive way to calculate an exact price that will be received by the PV producer per SREC over the next 15 years. Renewable Energy Consultants estimated an average of $487/ SERC per year and this number was utilized in the cash flow for this report. The library had a maximum kw demand of 92.9 kw and a minimum kw of 56.1 kw over the 12 months considered in this study. The monthly average over the observed 12 month period was 72 kw. The building s existing load should justify the use of a 20 kw of installed PV solar array; therefore, a 20 kw system size was selected for the calculations. The system costs for PV installations were derived from the most recent NYSERDA (New York State Energy Research and Development Agency) estimates of total cost of system installation. It should be noted that the cost of installation is currently $10 per watt or $10,000 per kw of installed system. This has increased in the past few years due to the rise in national demand for PV power generator systems. 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.

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. New Jersey BPU - Energy Audits Page 20 of 26

25 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 for the site would transfer the heat from the panels to thermal storage tanks and transfer solar produced thermal energy to use for domestic hot water production. As of the writing of this report, there are no incentives available for installation of thermal solar systems. Presently there is a federal tax credit of 30% of installation cost for the thermal applications; however, the Township of Roxbury does not pay federal taxes and, therefore, would not benefit from this program. The implementation cost and savings related to this ECM are presented in Appendix S and summarized as follows: ECM S2 Solar Thermal Domestic Hot Water Plant Budgetary Annual Utility Savings Total Cost Electricity Natural gas Total Savings New Jersey Renewable Payback Payback Energy (without (with Incentive incentive) incentive) $ kw kwh Therms $ $ $ Years Years 5, NA >30 NA * No incentive is available in New Jersey at this time. This measure is not recommended. 6.3 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 sliprings 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 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. Federal tax credits are also available for renewable energy projects up to 30% of installation cost for systems less than 100 kw. However, as noted previously, municipalities do not pay federal taxes and are, therefore, not eligible for the tax credit incentive. The most important part of any small wind generation project is the mean annual wind speed at the height of which the turbine will be installed. In the Roxbury New Jersey area, the map indicates a mean annual New Jersey BPU - Energy Audits Page 21 of 26

26 wind speed of below 10 miles per hour. For the building, there are site restrictions. Parking lots, radio communication towers, trees, and local residential housing would greatly affect a tower location. An aerial satellite image of the site and wind speed map is included in Appendix T. This measure is not recommended due to the low mean annual wind speed. 6.4 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 building some or all of the time, with the balance of electric needs satisfied by purchase from the grid. 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 Library 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, and thermal energy produced by the CHP plant 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. This measure is not recommended due to limited use of summertime heat. 6.5 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: New Jersey BPU - Energy Audits Page 22 of 26

27 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 This measure is not recommended because the site does not have room to store the waste organic materials, noise issues, and potential zoning issues. 6.6 Demand Response Curtailment Presently, the library has electricity delivered and supplied by Jersey Central Power and Lighting Corporation (JCP&L). Utility curtailment is an agreement with the regional transmission organization and an approved Curtailment Service Providers (CSP) to shed electrical load by either turning major equipment off or energizing all or part of a building utilizing an emergency generator, therefore reducing the electrical demand on the utility grid. JCP&L 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. This program is to benefit the utility company during high demand periods and JCP&L 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 their 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 their emergency generators with notice to test the system. A minimum of 100 kw of curtailable load is required to enter the program. Discussions with the EnerNoc Corporation, an approved CSP, indicate that existing emergency generators will not pass the emissions requirements to enter the program. Presently, the building does not have back-up generation. This measure is not recommended because the building does not have the ability to shed the required minimum load reduction.

28 7.0 EPA PORTFOLIO MANAGER The United State Energy Protection Agency (EPA) is a federal agency in charge of regulating environment waste and policy in the United States. The EPA has released the EPA Portfolio Manager for public use. The program is designed to allow property owners and managers to share, compare and improve upon their building s energy consumption. Inputting such parameters at electricity, heating fuel, building characteristics and location into the website based program generates a naturalized energy rating score out of 100. Once an account is registered, monthly utility data can be entered to track the savings progress and retrieve an updated energy rating score on a monthly basis. The building includes the main library area, office areas, breakroom, and utility rooms. Since more than 10% of the space is designated by EPA Portfolio Manager as Other-Library, the building does not fall under the listed space description categories needed to generate a full report and provide an energy star rating. The portfolio manager did provide energy intensity ratings of a site intensity of 159 kbtu/ft 2. The building s performance, however, can be compared to national site and source EUI averages. With a Source Energy Intensity of 159 kbtu/ft 2 /year, the building is considered a moderate-high energy consumer per the Portfolio Manager (Note: Average Site EUI for Libraries is 104 kbtu/ft 2 /year). Reducing energy loss associated with lighting retrofit, occupancy sensor installation, door seals, applying an energy management control system, replacing the boiler and domestic water heater, and RTU #2 will result in a more favorable score. If all the measures identified in this report are fully implemented, it is projected that a Source Energy Usage Index of 81 kbtu/ft 2 /year can be obtained. A full EPA Energy Star Portfolio Manager Report is located in Appendix U. The user name and password was provided to Valarie Wyble, Executive Assistant, Township of Roxbury.

Savings will result from the avoided heating and cooling of excessive outside air. Cooling System Eff kw/ton (Includes ancillary equipment) Heating System Eff. 65% (Includes distribution losses) Method: The outdoor air introduced into the spaces is currently constant based on design occupancy conditions. This ECM proposes the installation of CO2 sensors in the space to allow for reduced outdoor air flows when conditions allow. An average reduction of 50% is assumed possible with the implementation of DCV The DCV system will automatically adjust the outdoor air damper position through the EMS to reduce outdoor air flows based on indoor CO2 levels. This ECM has been interacted with the new boiler ECMs and accounts for the reduced operating hours of the unit via EMS scheduling.
