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 Atlantic City Free Public Library building is a 30,000 square foot facility consisting of two floors. The original building was constructed in 1985 and is physically attached to the Atlantic City County Offices, which is an eight story office building. An aerial of the building is shown below.

EXISTING CONDITIONS

3.1 Building - General Built in 1985, the Atlantic County Office building includes the Free Public Library at the first two floors. The office building is eight stories tall and is physically connected to the library by an enclosed two-story atrium. The library is accessed from Tennessee Avenue on the south and through the atrium to the north. The library occupies approximately 30,000 square feet, 15,000 per floor. In addition to the traditional library functions, the library also provides free loan of books on tape, DVDs, music CDs and provides free computer use for the public. The first floor contains mostly book, CD and DVD displays and has open space for reading and computer research. There is also a reproduction office and the Alfred M. Heston archive collection room located on the lower level. The second floor includes the children’s library, teen lounge, community classroom, and all of the library support staff offices (administration, IT, conference room, break room, staff bathrooms). The library has approximately 40 full and part time employees and appeared to be fully utilized by the public during our field inspection. The hours of operation are:

• Monday, Tuesday and Wednesday 9:30 am to 8 pm. • Thursday, Friday and Saturday 9:30 am to 5 pm • Sunday 12 pm to 5 pm.

The library maintains 102 public and staff use PC’s and has 17 laptops available as well. There are also 5 full sized office copy machines, scanners, printers and microfiche viewing machines. The building is constructed of a steel frame having block exterior walls with a limestone veneer. The interior walls are 3-5/8” metal studs filled with fiberglass insulation finished with gypsum board. The flat roof system is comprised of a 6” concrete deck having 3-1/2” of ridged foam insulation and a single ply EPDM membrane with stone ballast. The windows are double pane glazed with a dark grey tint mounted in aluminum frames. The entrance doors also aluminum with single pane storefront glass. The library is has exposed walls facing the east, west and south directions. The atrium and eight story office building are located on the north side. The building has no basement, first floor is at grade.

3.2 Utility Usage Utilities include electricity, natural gas, and potable water. The Library has only a water meter, no electric or natural gas meters. All electric and gas is supplied to and metered by the County office building. The Library pays for its electricity and gas usage based on a square footage comparison calculation between the library and the County building, which has been determined to be 20.08% of the total charges. Electricity is supplied by Hess and delivered by Atlantic City Electric. Natural gas supplied and delivered by South Jersey Gas. Potable water is provided by Atlantic City Municipal Utility Authority (MUA). January 2010 through December 2010, the combined electric usage was approximately 725,000 kWh at a cost of about $468,242.46. The library pays a fixed 20.08% of the utility bills, so it was responsible for $90,429.65. Review of electricity bills during this period showed that the complex was charged at the following rates: supply unit cost of $0.119 per kWh; demand unit cost of $6.32 per kW; and blended unit cost of $0.133 per kWh. Electrical usage was generally higher in the summer months when air conditioning equipment was operational. From January 2010 through March 2011, gas-fired equipment consumed about 9,775 therms of natural gas.

_____________________________________________________________________________ New Jersey BPU - Energy Audits

Based on the annual cost of $82,060.82, the blended price for natural gas was $1.66 per therm. Since the library pays a fixed 20.08% of the utility bills, its contribution to the natural gas bill was roughly $16,477.81. Natural gas consumption was highest in winter months for heating. See Appendix A for a detailed utility analysis. The delivery component of the electric and natural gas bills will always be the responsibility of the utility that connects the facility to the power grid or gas line; however, the supply can be purchased from a third party; as is currently the case with electricity. The electricity or natural gas commodity supply entity will require submission of one to three years of past energy bills. Contract terms can vary among suppliers. According to the U.S. Energy Information Administration, the average commercial unit costs of electricity and natural gas in New Jersey during the same periods as those noted above was $0.141 per kWh and $0.959 per therm. When compared to the average state values, it is recommended that the present electricity supplier be maintained and a third party natural gas supplier be pursued. A list of approved electrical and natural gas energy commodity suppliers can be found in Appendix A.

3.3 HVAC Systems The library is heated with hot water supplied by boilers located on the top floor of the County office building. The heating hot water is pumped to perimeter fin tube radiation, cabinet unit heaters and to pre-heat coils located in three air handling units that also provide the library ventilation and cooling. The perimeter fin tube is divided into four controlled zones per floor, totaling 8 zones. Additional fin tube is located above the ceiling of the second floor to re-heat the return air. Cooling and ventilation is not provided by County office building systems, they are dedicated just to the library. Two of the three air handling units are actually self-contained Carrier HVAC units, as they include the cooling compressors, condenser fans, evaporator coils and fans into one cabinet. There are two identical units located on the second floor that serve a small portion of the first floor and the entire second floor. These units are completely self-contained and generate 8000 CFM each and approximately 40 tons of cooling. The third unit, which is located on the first floor serves the first floor only and has a separate condenser section that is piped to the compressors. This unit has a total air flow of 12,000 CFM and a cooling capacity of 30 tons. All of the air handling units draw fresh air in from the exterior through sidewall louvers and all of the units dispel hot condenser air to the exterior through similar sidewall louvers. The supply air duct feeds multiple parallel fan powered variable air volume (VAV) boxes located above the suspended ceilings. All of the return air is drawn back to the units through the plenum ceiling. The VAV boxes do not have any hot water reheat coils, however they do have motorized by-pass dampers that allow warm return air to mix with the supply air. This is basically a constant volume system that uses the by-pass feature of the VAV boxes to re-circulate the return air back through the VAV box when the zone thermostat is satisfied. The entire HVAC system is vintage 1985 and is showing signs of degradation. The outdoor air dampers do not seal properly and it was reported by the facilities director that the heating coils are in poor condition and could fail at any time. Each air handling unit has a pan-type humidifier that does not function. The elevator machine room is accessed only from the exterior and has a louvered door, presumably for ventilation. A ceiling mounted electric unit heater tries to maintain the space at 50 F, but has difficulty doing this on cold days. To maintain the hydraulic fluid at a viscous temperature, a supplemental immersion heater has been added.

Page 9: ATLANTIC CITY FREE PUBLIC LIBRARY ENERGY ASSESSMENT …City+Free... · ATLANTIC CITY FREE PUBLIC LIBRARY ENERGY ASSESSMENT for ... music CDs and provides free computer use for the

_____________________________________________________________________________ New Jersey BPU - Energy Audits

The small server room on lower level has a “Movin Cool” portable 23,300 BTU/H air conditioning unit that is set to maintain the space at 68 F. The condenser duct discharges into the return air plenum. This unit appears to be relatively new. There are two roof mounted toilet room exhaust fans that serve multiple rooms. There are also two utility set fans that are mounted to the end of each glass skylight to provide smoke control in the event of a fire. These fans can also be manually operated to provide general ventilation. Specifics on mechanical equipment can be found within the equipment inventory located in Appendix B.

3.4 Control Systems All of the library HVAC controls are Barber Coleman pneumatic controls. There is no user interface available, all set points are manually adjusted by the occupants or default settings within the control panel. The control sequence seems to be that the perimeter fin tube heating is always available, 24/ 7 and controlled to maintain 72 F by wall mounted thermostats located in each room (zone). Based on varying water temperature measurements, it appears that the perimeter hot water supplied by the main boilers is on an outdoor air reset schedule. The main ventilation (and cooling) air handlers provide tempered ventilation air using hot water coils having three –way mixing valves. These units appeared to be operated by a time clock to come on during occupied times only. The units provide a morning warm-up sequence and then revert to a constant discharge air temperature. The outdoor air dampers appear to be fixed at a semi-opened position. The cooling is enabled while the building is occupied (based on the same time clock settings) and can provide cooling when the space temperatures exceed 74 F. It is possible that simultaneous heating and cooling can occur. It does not appear that economizer cycle is being implemented. Each VAV box has a wall mounted thermostat to regulate the cooling to each zone. Cooling is typically maintained at 74 F during occupied times. A duplex 5 HP air compressor provides the control air to the pneumatic system. The exhaust fans appear to operate 24/ 7, however one fan was not operational at the time of our inspection, possible due to a motor failure. In General, the pneumatic HVAC controls operate only as a time clock to turn the main HVAC units on or off. The library is otherwise maintained at a constant winter temperature of 72 F and a constant summer temperature of 74 F.

3.5 Lighting/Electrical Systems The interior lighting system consists mainly of type types of fixtures/ lamp. The predominant fixtures are four foot single lamp T-12 34 watt recessed fluorescent fixtures that illuminate the book stacks and perimeter offices. Very few of these lights have been upgraded to T-8 lamps. All ballasted are magnetic type. The second prevalent fixture type is recessed spots having 24 volt

Page 10: ATLANTIC CITY FREE PUBLIC LIBRARY ENERGY ASSESSMENT …City+Free... · ATLANTIC CITY FREE PUBLIC LIBRARY ENERGY ASSESSMENT for ... music CDs and provides free computer use for the

_____________________________________________________________________________ New Jersey BPU - Energy Audits

par 56 watt incandescent lamps. Other fixtures include pendent type decorative lamps having 60 -75 watt incandescent lamps. All interior lights are switched manually. Exterior lights consist of unique pole mounted decorative lights (which were observed to be inoperative), bollard type delineating lights having 60 watt incandescent lamps (also mostly inoperative) and several recessed incandescent fixtures located in the entrance alcoves which have PAR type 75 watt lamps (of which 50% were inoperative). The Library also has three large metal halide spot lights mounted to the roof edge, however these lights are operated and maintained by the County. All exterior lighting is controlled by timers.

3.6 Plumbing Systems Water is provided by Atlantic City MUA and sewer services are provided by the Atlantic City Sewerage Department. A six inch water service enters the building at the first floor in the south-west corner and passes through a 2-1/2” water meter for domestic use and a 6” supervised riser for fire protection. The cold water is provided to 15 lavatories, 15 water closets, 4 urinals, 2 kitchen sinks, and 2 water coolers. The water closets and urinals have standard, manual 3.5 GPF flush valves and the lavatories have 2.5 GPM battery powered infrared faucets. Domestic hot water is produced by a single 40 gallon electric water heater having two (2) 4500 watt elements.

4.0 ENERGY CONSERVATION MEASURES

4.1 ECM-1 Boiler Installation The current library heating system is a separate hot water zone supplied by the main boilers located in the adjacent County office building. The County office building operates on a different schedule than the library, so heated hot water is always available during winter months. The County office boilers are standard efficiency fire-tube boilers, assumed to be operating between 75 and 82 % efficiency. The hot water supplied to the library is on a reset schedule that lowers the delivered water temperature based on the outdoor air temperature, which improves the overall system efficiency. The library has control valves located in the perimeter fin tube to regulate the amount of heat to each space. This ECM includes adding a dedicated gas boiler and pumps for the library and disconnecting the library from the main building heating system. An energy efficient condensing boiler would provide all of the heat for the library and be controlled to operate only as required for library occupancy. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

4.2 ECM-2 HVAC System Replacement The current library HVAC system consist of self-contained cooling units having hot water heating coils, constant volume supply fans and by-pass type variable air flow (VAV) boxes. The system has exceeded its useful life and is energy inefficient as compared to today’s standards. This ECM includes removing the three self-contained units and all VAV boxes and replacing them with three new indoor HVAC air handling units having hot water coils supplied by the ECM-1 boiler (or main boilers) and chilled water coils supplied by a new roof mounted, air cooled chiller. The by-pass VAV boxes would be replaced with regular modulating VAV boxes to form a true variable air volume system. This will also permit the use of variable speed drives for the main fans.

4.3 ECM-3 HVAC Controls Replacement The current library HVAC controls system consist of an antiquated pneumatic controls system that has little energy savings capabilities. This ECM proposes to replace this entire pneumatic system with a Direct Digital Control System that will enable the building facility operator to:

• Schedule the HVAC system to maintain higher/ lower temperatures during unoccupied times (unoccupied set back)

• Schedule the bathroom exhaust fans to operate only during occupied times. • Control of the outdoor air dampers based on actual carbon dioxide levels (CO2) • Control of the outdoor air dampers to provide economizer cooling rather than mechanical

cooling • Control and of the discharge air temperature based on actual internal loads (discharge air

reset) • Prioritize the HVAC system start-up time to reduce the peak demand (demand load

shedding) • Control the start/ stop times and temperatures to match the actual heat gain/ loss that the

building experiences based on outdoor temperature. (optimum Start/Stop) • Provide a means of measuring the duct static pressures (which will vary due to the new

VAV boxes discussed in ECM-2), and allow the main system fan speed to be controlled. Additional benefits of this system are that it can provide useful trending information to the owner such as daily, monthly and seasonal energy usage and also provide alarm messages to the facilities operator via the internet indicating that a piece of equipment needs repair or maintenance. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

4.4 ECM-4 Lighting Replacement and Lighting Controls The current library lighting consist of an antiquated fixtures having T-12 34 watt lamps and recessed can fixtures having PAR incandescent lamps and electronic ballasts. This ECM proposes to replace the florescent fixtures with similar troffer style florescent fixtures having Super T-8- 28 watt lamps with electronic ballasts and also to replace all of the recessed PAR fixtures with new recessed fixtures having LED lamps. Although the exterior bollard lighting was for the most part inoperative, the fixtures are not energy efficient and therefore it is recommended that these fixtures be replaced with LED lamped bollard fixtures. The current street lights have a unique design and should be refurbished and retrofitted with CFL type lamps. These lights are more decorative in nature than intended to provide high lighting levels. The current library lighting is controlled by manual switches located at several gang switch boxes. The lights are manually turned on in the morning and shut off at night. During occupied times, there are rooms that are not occupied, however the lights remain on. Adding occupancy controls to the individual rooms will automatically control the lights based on actual occupancy. These 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 recommend in public toilet rooms.

4.5 ECM-5 Add Door Seals The exterior doors have a 3/8” gap between the two leafs permitting outdoor air to infiltrate the library which adds load to the HVAC. This ECM includes adding new door seal to these main entrance doors to reduce the amount of infiltration.

4.6 ECM- 6 Elevator Machine Room Upgrades The elevator machine room is accessed from the exterior only. The door has a 16” X 20” louver that permits cold air to enter the room. A wall mounted 5 KW electric heater then heatsd this air to maintain the hydraulic fluid at a viscous temperature. On cold days, this unit heater cannot sufficiently heat the space and the fluid, which made it necessary for the library to add a supplemental electric immersion heater to the hydraulic fluid tank. This ECM includes adding a new door seal and adding a tight-sealing motorized damper to the louver, controlled by internal space temperature. The damper would remain closed until the space reached 70 F , at which time it would open to provide ventilation.

4.7 ECM-7 Network Controller Software The library currently has 107 PC’s that are used daily by the public and by staff members. The implementation of Network Controller Software will enable the Ethernet Network to go into a deep sleep mode during times of low usage (typically unoccupied times) without affecting the Network’s ability to perform necessary updates and after hours tasks. The PC Wattage will be reduced which will result in electrical energy savings. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

4.8 ECM-8 Point of Use Electric Water Heaters The library currently has a single 40 gallon electric water heater having two -4500 watt electric elements that provide hot water to the lavatories and sinks, which are relatively far from the water heater. Domestic hot water use is only needed momentarily for hand washing, yet 40 gallons of 120 F hot water is produced and stored. To make matters worse, the hot water re-circulation system is not operational, so the hot water never makes it to the fixtures when it is needed. By replacing this single tank-type water heater an re-circulation pump system with six small instantaneous electric water heaters, only the small amount of hot water that is needed to wash your hands is produced and available at the faucets.

4.9 ECM-9 Replace Plumbing fixtures with Low Consumption Fixtures The facility has a mixture of older style fixtures and newer style fixtures in the restrooms. The older style fixtures consume more water than modern plumbing fixtures. It was determined that there are 20 fixtures with an average water use of 3.5 gal/flush. Per the number of occupants, it was estimated that each toilet and faucet is utilized approximately nine times per day. The water savings associated from replacing these fixtures with low-flow fixtures was calculated by taking the difference of the annual water usage for the proposed and base case. The basis of this calculation is the number of times each fixture is used, gallons per use, and number of fixtures. Replacing the existing fixtures in the restrooms with 1.28 gals/flush toilets would save $6,200 annually. The implementation cost and savings related to this ECM are presented in Appendix C and summarized below:

5.0 PROJECT INCENTIVES

5.1 Incentives Overview 5.1.1 New Jersey Pay For Performance Program The facility will be eligible for incentives from the New Jersey Office of Clean Energy. The most significant incentives will be from the New Jersey Pay for Performance (P4P) Program. The P4P program is designed for qualified energy conservation projects in facilities whose demand in any of the preceding 12 months exceeds 200 kW. However, the 200 kW/month average minimum has been waived for buildings owned by local governments or municipalities and non-profit organizations. 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). The standard incentive pays $0.10 per square foot, up to a maximum of $50,000, not to exceed 50% of facility annual energy cost, paid after approval of application. For building audits funded by the New Jersey Board of Public Utilities, which receive an initial 75% incentive toward performance of the energy audit, facilities are only eligible for an additional $0.05 per square foot, up to a maximum of $25,000, rather than the standard incentive noted above. Incentive #2: Installation of Recommended Measures – This incentive is based on projected energy saving and designed to pay approximately 60% of the total performance-based incentive. Base incentives deliver $0.11/kWh and $1.10/therm not to exceed 30% 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. 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 provide a total of $0.18/ kWh and $1.8/therm not to exceed 50% of total project cost. Additional incentives for #2 and #3 are increased by $0.005/kWh and $0.05/therm for each percentage increase above the 15% minimum target to 20%, calculated with the EPA Portfolio Manager benchmarking tool, not to exceed 50% of total project cost. Under incentive #1 of the New Jersey Pay for Performance Program, the 30,000 square foot Library is eligible for about $1,400 toward development of an Energy Reduction Plan. When calculating the total amount under Incentives #2 and #3, all energy conservation measures are applicable as the amount received is based on site wide energy improvements. Since the overall energy reduction for the complex is estimated to exceed the 15% minimum, the building is eligible to receive monies based on Incentives #2 and #3 as discussed above in section 5.1.1. In total, incentives through the NJ P4P program are expected to total about $43,257, reducing the total project payback from 4.9 years to 3.5 years. See Appendix D for calculations.

5.1.2 New Jersey Smart Start Program For this program, specific incentives for energy conservation measures are calculated on an individual basis utilizing the 2011 New Jersey Smart Start incentive program. This program provides incentives dependent upon mechanical and electrical equipment. If applicable, incentives from this program are reflected in the ECM summaries and attached appendices. If the 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. 5.1.3 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. If a building is eligible for this funding, the Direct Install Program can significantly reduce the implementation cost of energy conservation projects. The program pays a maximum amount of $75,000 per building, and up to $250,000 per customer per year. Installations must be completed by a Direct Install participating contractor, a list of which can be found on the New Jersey Clean Energy Website at http://www.njcleanenergy.com. Contractors will coordinate with the applicant to arrange installation of recommended measures identified in a previous energy assessment, such as this document. The facility is potentially eligible to receive funding from the Direct Install Program. The total implementation cost for all ECMs potentially eligible for Direct Install funding is about $54,000 and installing HVAC controls and lighting system upgrades. The program would pay 70%, or about $32,400 of these initial costs, leaving only $21,600 to be paid out of pocket. Direct Install funding has the potential to significantly reduce the payback period of Energy Conservation Measures. For the Municipal Complex, the Direct Install Program brings the simple payback of all measures from about 8.6 years, to approximately 6.0 years.

6.0 ALTERNATIVE ENERGY SCREENING EVALUATION

6.1 Solar 6.1.1 Photovoltaic Rooftop Solar Power Generation The facility was evaluated for the potential to install rooftop photovoltaic (PV) solar panels for power generation. Present technology incorporates the use of solar cell arrays that produce direct current (DC) electricity. This DC current is converted to alternating current (AC) with the use of an electrical device known as an inverter. The building’s roof has sufficient room to install a large solar cell array, however due to the age of the roof (27 years) and the anticipated HVAC system changes, it is not advisable to proceed with a permanent PV array at this time. Once this rehabilitation work is completed, adding a PV should be considered. The Library has already received some proposals for adding PV arrays to the roof. The PVWATTS solar power generation model was utilized to calculate PV power generation. The closest city available in the model is Philadelphia, Pennsylvania and a fixed tilt array type was utilized to calculate energy production. The PVWATT solar power generation model is provided in Appendix E. The State of New Jersey incentives for non-residential PV applications is $0.75/watt up to 30 kW of installed PV array with a maximum system capacity of 50 kW. 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. One SREC credit is equivalent to 1000 kilowatt hours of PV electrical production; these credits can be traded for period of 15 years from the date of installation. The average SREC value per credit is estimated to be about $95/ SREC per year based on current market data, and this number was utilized in the cash flow for this report. From May 2010 through April 2011 the Atlantic City Free Public Library had a maximum electricity demand of 174 kW and a minimum of 99 kW. The monthly average over the observed 12 month period was 139 kW. The existing load justifies the use of the maximum incentive cap of 50 kW of installed PV solar array; where incentives can be applied to only 30 kW of the system. 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 $8.00 per watt or $8,000 per kW of installed system, for a 50 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.

This measure is not recommended. 6.1.2 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. Domestic hot water is presently produced by a relatively small electric water heater which is recommended to be replaced by several smaller point of use water heaters due to the small hot water demand. As an alternative, the solar DHW system could supplement the existing electric water heater which would offer some electricity savings, but would most likely be cost prohibitive. 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.

6.2 Demand Response Curtailment Presently, electricity is delivered by Atlantic City Electric, which receives the electricity from regional power grid RFC. Atlantic City Electric is the regional transmission organization (RTO) that coordinates the movement of wholesale electricity in all or parts of 13 states and the District of Columbia including the State of New Jersey. Utility Curtailment is an agreement with the utility provider’s regional transmission organization and an approved Curtailment Service Provider (CSP) to shed electrical load by either turning major equipment off or energizing all or part of a facility utilizing an emergency generator; therefore, reducing the electrical demand on the utility grid. This program is to benefit the utility company during high demand periods and utility provider offers incentives to the CSP to participate in this program. Enrolling in the program will require program participants to drop electrical load or turn on emergency generators during high electrical demand conditions or during emergencies. Part of the program also will require that program participants reduce their required load or run emergency generators with notice to test the system. A pre-approved CSP will require a minimum of 100 kW of load reduction to participate in any curtailment program. From May 2010 through April 2011 the Atlantic City Free Public library had a maximum electricity demand of 99 kW and a minimum of 174 kW. The monthly average over the observed 12 month period was 139 kW. Atlantic City Free Public Library currently does not have their own independent electric meter, however should this change the Library could consider pursuing Demand Response Curtailment.

7.0 EPA PORTFOLIO MANAGER The EPA Portfolio Manager benchmarking tool was used to assess the building’s energy performance. Portfolio Manager provides a site and source Energy Use Intensity (EUI), as well as an Energy Star performance rating for qualifying building types. The EUIs are provided in kBtu/ft2/year, and the performance rating represents how energy efficient a building is on a scale of 1 to 100, with 100 being the most efficient. In order for a building to receive and Energy Star label, the energy benchmark rating must be at least 75. As energy use decreases from implementation of the proposed measures, the Energy Star rating will increase. The site EUI is the amount of heat and electricity consumed by a building as reflected in utility bills. Site energy may be delivered to a facility in the form of primary energy, which is raw fuel burned to create heat or electricity, such as natural gas or oil; or as secondary energy, which is the product created from a raw fuel such as electricity or district steam. To provide an equitable comparison for different buildings with varying proportions of primary and secondary energy consumption, Portfolio Manager uses the convention of source EUIs. The source energy also accounts for losses incurred in production, storage, transmission, and delivery of energy to the site, which provide an equivalent measure for various types of buildings with differing energy sources. The results of the Portfolio Manager benchmarking tool are contained in the table below. Building Site EUI kBtu/ft2/yr Source EUI

kBtu/ft2/yr Energy Star Rating

(1-100) Atlantic City Free Public Library

114 308 N/A

The Atlantic City Library is considered a higher than average energy consumer by the Portfolio Manager with a Site EUI of 114 kBtu/sf/year, and Source EUI of 308 kBtu/sf/year (see Appendix G for a detailed Portfolio Manager report). The national average Site EUI for similar Library buildings is 92 kBtu/sf/year, and average Source EUI is 246 kBtu/ft2/year. The Library Source EUI is about 25% higher, therefore, slightly less efficient than the national average . The ENERGY star rating does not apply for this building type. The Portfolio Manager account can be accessed by entering the username and password shown below at the login screen of the Portfolio Manager website (https://www.energystar.gov/istar/pmpam/). The account has been shared with the NYSERDABENCHMARKING master account. Username: atlanticcitylib Password: energystar A full EPA Energy Star Portfolio Manager Report is located in Appendix G. The user name and password for the building’s EPA Portfolio Manager Account has been provided to Maureen Frank, library Director, Atlantic City Free Public Library.

8.0 CONCLUSIONS & RECOMMENDATIONS The energy audit conducted by CHA at the Atlantic City Free Public library in Atlantic City, New Jersey identified the following potential ECMs:

• HVAC Equipment Replacement • HVAC Control Replacement • Lighting Replacement • Plumbing Fixture Replacement • Envelope Improvements • Renewable Energy Technologies (Solar PV)

Potential annual savings of $40,400 may be realized for the recommended ECMs, with a summary of the costs, savings, and paybacks as follows:

The Atlantic City Free Public Library appears to be an excellent candidate for solar PV due to its open flat roof and open southern exposure. A solar array should be pursued further after all other renovation work is complete including any potential re-roofing and HVAC upgrades. Solar domestic hot water is less attractive primarily due to the low hot water usage and lack of incentives available. Other renewable energy technologies such as geothermal heat pumps and wind turbines would be not be practical for this building having significant first costs and difficult if not prohibitive permitting processes. As the library is currently not sub-metered from the main gas and electrical services provided to the Atlantic City County Building, a recommended first step would be to install sub-meters and BTU meters to get actual utility usage data for a period of one year and also establish a baseline building model using load building modeling software to verify the annual consumption of the lighting, plug loads and HVAC equipment. This model could then be used to simulate potential system upgrades and consequent energy savings which would aid in selection of the new equipment and provide investment grade cash flows for each option considered.

SA Set point, Winter 72.0 °FDescription: SA Set point, Summer 74.0 °FOutside air can be significantly reduced for most of the time that the building is occupied. 55.0 °FSavings will result from the avoided heating and cooling of excessive outside air. Cooling System Eff. 1.50 kW/Ton (Includes ancillary equipment)

Heating System Eff. 80% (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 DCVThe 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.

Pay for Performance - Existing BuildingsDownload program applications and incentive forms.

The Greater the Savings, the Greater Your Incentives

Take a comprehensive, whole-building approach to saving energy in your existing facilities and earn incentives that are directly linked to your savings. Pay for Performance relies on a network of

program partners who provide technical services under direct contract to you. Acting as your energy expert, your partner will develop an energy reduction plan for each project with a whole-building technical component of a traditional energy audit, a financial plan for funding the energy efficient measures and a construction schedule for installation.

Eligibility

Existing commercial, industrial and institutional buildings with a peak demand over 100 kW for any of the preceding twelve months are eligible to participate including hotels and casinos, large office buildings, multi-family buildings, supermarkets, manufacturing facilities, schools, shopping malls and restaurants. Buildings that fall into the following five customer classes are not required to meet the 100 kW demand in order

to participate in the program: hospitals, public colleges and universities, 501(c)(3) non-profits, affordable multifamily housing, and local governmental entities. Your energy reduction plan must define a comprehensive package of measures capable of reducing the existing energy consumption of your building by 15% or more.

Exceptions to the 15% threshold requirement may be made for certain industrial, manufacturing, water treatment and datacenter building types whose annual energy consumption is heavily weighted on process loads. Details are available in the high energy intensity section of the FAQ page.

ENERGY STAR Portfolio Manager

Pay for Performance takes advantage of the ENERGY STAR Program with Portfolio Manager, EPA's interactive tool that allows facility managers to track and evaluate energy and water consumption across all of their buildings. The tool provides the opportunity to load in the characteristics and energy usage of your buildings and determine an energy performance benchmark score. You can then assess energy management goals over time, identify strategic opportunities for savings, and receive EPA recognition for superior energy performance.

This rating system assesses building performance by tracking and scoring energy use in your facilities and comparing it to similar buildings. That can be a big help in locating opportunities for cost-justified energy efficiency upgrades. And, based on our findings, you may be invited to participate in the Building Performance with ENERGY STAR initiative and receive special recognition as an industry leader in energy efficiency.

Incentives

Pay for Performance incentives are awarded upon the satisfactory completion of three program milestones:

Incentive #1 - Submittal of complete energy reduction plan prepared by an approved program partner - Contingent on moving forward, incentives will be between $5,000 and $50,000 based on approximately $.10 per square foot, not to exceed 50% of the facility's annual energy expense.Incentive #2 - Installation of recommended measures - Incentives are based on the projected level of electricity and natural gas savings resulting from the installation of comprehensive energy-efficiency measures.Incentive #3 - Completion of Post-Construction Benchmarking Report - A completed report verifying energy reductions based on one year of post-implementation results. Incentives for electricity and natural gas savings will be paid based on actual savings, provided that the minimum performance threshold of 15% savings has been achieved.

A detailed Incentive Structure document is available on the applications and forms page.

Energy Efficiency Revolving Loan Fund (EE RLF)

New Jersey-based commercial, institutional or industrial entities (including 501(c)(3) organizations) that have received an approved energy reduction plan under Pay for Performance may be eligible for supplemental financing through the EE RLF. The financing, in the form of low-interest loans, can be used to support up to 80% of total eligible project costs, not to exceed $2.5 million or 100% of total eligible project costs from all public state funding sources. Visit the NJ EDA website for details.
