8 Cherry Hill Twp BOE Cherry Hill High School West Energy Audit II. FACILITY DESCRIPTION The Cherry Hill Township BOE Cherry Hill High School West is located on 2101 Chapel Avenue West, Cherry Hill, NJ The original building constructed in 1959 was 125,900 SF. Three additions were added in 1964 a 126,090 SF addition, in ,325 SF, and in 1994 a 13,230 SF addition. The building is a total of 272,580 SF, divided into wings A through H, and contains multiple levels. Occupancy Profile The typical hours of operation for the school students and teachers are between 7:30 AM and 2:30 PM on the weekdays. The facility remains occupied till 8:00 PM for afterschool activities as well as the custodial services. The facility is open on Saturdays and Sundays for sports activities. The student enrollment at the Cherry Hill High School West is approximately 1,585. Estimated total number of staff is 150. Building Envelope The exterior walls of the original building construction are a brick and block type with minimal insulation that would be typical for a building constructed in the 1960 s. It is estimated that due to the age, the building envelope is not as tightly insulated as new construction would provide. Windows have been replaced from the original construction with double pane ¼ thermal panels with aluminum frames. The weather stripping and caulking on the outside of the windows is in good to fair condition. Blinds are utilized in the building for occupant comfort, and provide a minimal amount of solar heat gain in the summer months. The building contains a built up roofing system. It was replaced at an undetermined point during the building s life cycle and is currently maintained by building staff to prevent roof failures and leaks. Roof insulation could not be determined based on a visual inspection, but it is assumed to be minimal. HVAC Systems Heating for part the building is provided through a heating hot water loop and boilers. These systems are described in a brief description below: Heating Plant: The heating plant is split between two separate boiler rooms. The first room operates two Cleaver Brooke CB900 natural gas fire tube boilers. The boiler provide approximately half of the heating hot water for the school, with an input of 8369 MBH per boiler and an efficiency of 72%. The boilers there are in poor condition and have exceeded their useful service life. The second boiler room contains an additional two Cleaver Brooks CB552 natural gas fire tube boilers. The boilers operate each with a heating input of 8,375 MBH and an efficiency of 72%. These boilers however are much older than the units in boiler room one. Each unit is 48 years old, poor condition, and well past the service life as defined by ASHRAE. Concord Engineering Group, Inc. 9C11001 October 11, 2011 FINAL Page 7 of 33

9 Cherry Hill Twp BOE Cherry Hill High School West Energy Audit Located in boiler room one is a series of Bell & Gossett zone pumps. These end suction pumps range from 1.5 to 5 HP and provide heating hot water pumping from the boiler to the various building zones labeled A through E. The pumps range in efficiency from 87.5% to 82.5% though none of them are classified based on inspection as NEMA motors. Specific serial number information could not be gathered off the nameplate, therefore the age of the pumps could not be estimated. In addition some of the pumps were being replaced while the survey was taking place so some data is subject to change with the new pumps. The second boiler room houses two Bell & Gossett end suction pumps. The pumps operate with a constant 1760 RPM, 15 HP motor, and provide ft head. Based on inspection the pumps were determined to be 35 years old, therefore exceeding their useful service life by 15 years. The pumps should be replaced with high efficiency pumps and motors. Cherry Hill High School West contains a number of packaged rooftop units and heat pump unit ventilators that provide both heating and cooling to the areas. Those systems and the areas that they serve are briefly summarized below. Music Wing and Auditorium: The music wing of the building receives both heating and cooling from four packaged units on the roof. A single McQuay model RPS020CSA unit provides 20 Tons of cooling with an efficiency of 10 EER. The unit uses forced draft as a gas fired furnace to provide the area with 250 MBH of heating input. The unit was installed in 2000 and is in good condition, within its useful service life. The music wing receives additional cooling and heating from a Trane packaged unit with an output of 15 cooling Tons at 9.6 EER. The natural gas combustion burner has an efficiency of 80% and provides 250 MBH of heating to the area. The Trane unit is still operating within its useful service life based on the site inspection. The music wing roof also contains two McQuay model RPS0400LA rooftop packaged units which provide room condition to the auditorium. These units operate with newer R- 410A cooling capabilities and provide 40 Tons of cooling per unit. The forced draft gas fired furnace in each unit is able to provide 500 MBH of heating input per unit with a gas combustion efficiency of 80%. Cafe: The café receives room heating and cooling from a Trane rooftop packaged heating and cooling unit. This natural gas unit provides heating of 150 MBH to the area. The R- 22 DX cooling has a capacity of 12.5 Tons and an efficiency of 9.6 EER. The unit based on a visual site inspection is in good condition still within the useful service life. An additional packaged heat pump located above the café adds additional cooling and heating to the space. The 13 Ton Addison unit operates with an efficiency of 11 EER and provides heating using a heat pump. The unit appeared in good condition and was nine years old. H-Wing: The H-Wing of the building contains six roof installed packaged units from York. The units each provide 10 Tons of DX R-22 cooling to areas located in the H-Wing Concord Engineering Group, Inc. 9C11001 October 11, 2011 FINAL Page 8 of 33

10 Cherry Hill Twp BOE Cherry Hill High School West Energy Audit of the school. The units also provide heating for the space, with each gas fired combustion section providing 245 MBH of heating at an operating efficiency of 80%. Each unit also contains an attached economizer. The units however appear in poor condition and have exceeded their useful life, based on the inspection the units are 25 years old. Heat Pump Unit Ventilators: AAF unit ventilators are located throughout the classrooms of D-Wing. These unit ventilators provide combined heating and cooling to the classrooms. The unit ventilators were recently installed in 2010, they contain modern R- 410A cooling capabilities, though they are not as highly efficient as some model, they currently have a 10.1 SEER rating with a capacity of 3 Tons. The units also provide heating to the classrooms through the use of heat pump with an estimated heating capacity of 40 MBH. Cooling for sections of the building are provided by a chilled water loop and split system condensing units. A brief description of these units is provided below. Chilled Water Loop: Cooling for the D-wing is provided by unit ventilator heat pumps. The chilled water loop extends from D-wing to a separate trailer outside which contains a cooling tower atop along with pumps, variable frequency drives and heat exchangers inside. These Trane heat pumps are approximately 6 tons each with an efficiency of 10.1 SEER. These units are only one to three years old and within their useful service life. Music Wing: Cooling in the music wing is supplemented by a series of split system condensing units. Two Trane condensing units provide 4 Tons of cooling at an efficiency of 10 SEER. Two more Trane condensing units provide an additional 2.5 Tons of cooling each with an efficiency of 10 SEER. The units are nine years old and within their useful service life. These units provide additional cooling to the packaged units described previously. E-Wing Roof: Cooling for the E-Wing is provided by a single Lennox DX split system condensing unit with a cooling capacity of 5 Tons and an efficiency of 14 SEER. The unit is connected to a 7.5 HP motor energy recovery unit. Exhaust System Air is exhausted from the toilet rooms through the roof exhausters. HVAC System Controls The building HVAC is controlled by a Honeywell DDC controller that converts the existing pneumatic room systems to DDC use P/E switches. The original equipment from 1956 has all pneumatic controls that control room or zone thermostats. The addition in 2001 is fitted with single zone thermostats to allow them to be monitored and controlled from the space. The addition room thermostats are currently set between F. This system uses a modem allowing information to be sent to the administration building to be Concord Engineering Group, Inc. 9C11001 October 11, 2011 FINAL Page 9 of 33

The system monitors the outside air temperature, status of hot water pumps, air compressor, boiler failure, and hot water supply temperatures. This system is capable of shutting down systems in the building or adjusting the minimum unoccupied set points in building zones. Domestic Hot Water Boiler Room #1: A fire tube boiler is located within boiler room #1 to provide domestic hot water to the building. This boiler operates with an input capacity of 2,092 MBH. A visual inspection of the unit was used to determine the condition of the unit. The boiler is currently in poor condition and has exceeded its useful service life. The boiler could be replaced with a more conventional domestic hot water system to increase efficiency. Boiler Room #2: The second boiler room contains an AO Smith domestic hot water tank heater to supply hot water for use in the building kitchens and bathrooms facilities. The unit has a capacity of 100 gallons, with an input capacity of 199 MBH, and a recovery rate of 192 gallons per hour. The unit is estimated to operate with an efficiency of 80%, the unit was recently replaced in 2008, but a newer high efficiency unit could offer increased energy savings. Electric Hot Water Heater: In addition to the gas fired heaters an electric hot water heater is used to provide hot water for school bathrooms. The AO Smith unit has a capacity of 50 gallons, with a heating input of 9 KW. The unit was installed in 2008 and is in good condition. Lighting and Electronics Cherry Hill High School West contains a mixture of newer LCD based computer monitors and CRT monitors. Based on the building survey approximately half of the monitors in use are of CRT type. The CRT monitors use additional power and lack the energy saving features of newer model LCD monitors. In addition the majority of classrooms contain a CRT television for displaying content to students. A number of CRT televisions are also used on pushcarts to display content to students in other areas of the school. Refer to the Investment Grade Lighting Audit Appendix for a detailed list of the lighting throughout the facility and estimated operating hours per space.

16 Cherry Hill Twp BOE Cherry Hill High School West Energy Audit ECM #1: Lighting Upgrade Description: There are still some T-12 fixtures throughout the Cherry Hill High School West. Improved fluorescent lamps and ballasts are available as direct replacements for the existing lamps and ballasts. A simple retrofit of the existing fixture can provide substantial savings. For example, a conventional drop-ceiling lay in fixture with four, 4-foot lamps (34 Watt lamps with magnetic ballast) has a total wattage of 144 Watts per fixture. By using T-8 lamps and electronic ballasts, the total wattage would be reduced to 86 Watts. The light levels would increase by about 15% and the light quality would increase by 35%. Some of the remaining interior lighting at the Cherry Hill High School West is provided with fluorescent fixtures with older generation, 700 series 32W T8 lamps and electronic ballasts. Although 700 series T8 lamps are considered fairly efficient, further energy savings can be achieved by replacing the existing T8 lamps with new generation, 800 series 28W T8 lamps without compromising light output. CEG recommends, re-lamping all of the fixtures with 28W T8 lamps. This ECM includes retrofitting each of the existing T-12 fluorescent lamp and magnetic ballast fixtures with T-8 lamps and high-power electronic ballasts. High efficiency electronic ballasts reduce overall wattage while maintaining the existing lumen levels of the various rooms. This ECM also includes re-lamping of the existing fluorescent fixtures with 800 series, 28W T8 lamps. Additionally, the retrofit of all older fluorescent fixtures with T8 or T5 fluorescent fixtures with electronic ballasts in the building would prove to be more energy efficient. The new, energy efficient T8 fixtures will provide adequate lighting and will save on electrical costs due to better performance of the lamp and ballasts. This ECM also includes maintenance savings through the reduced number of lamps replaced per year. The expected lamp life of a T8 lamp is approximately 30,000 burn-hours, in comparison to the existing T12 lamps which is approximately 20,000 burn-hours. The facility will need approximately 33% less lamps replaced per year for each one for one fixture replaced. The ECM also includes replacement of any incandescent lamps with compact fluorescent lamps. Compact fluorescent lamps (CFL s) were designed to be direct replacements for the standard incandescent lamps which are common to table lamps, spot lights, hi-hats, bathroom vanity lighting, etc. The light output of the CFL has been designed to resemble the incandescent lamp. The color rendering index (CRI) of the CFL is much higher than standard fluorescent lighting, and therefore provides a much truer light. The CFL is available in a myriad of shapes and sizes depending on the specific application. Typical replacements are: a 13-Watt CFL for a 60-Watt incandescent lamp, an 18-Watt CFL for a 75-Watt incandescent lamp, and a 26-Watt CFL for a 100-Watt incandescent lamp. The CFL is also available for a number of brightness colors that is indicated by the Kelvin rating. A 2700K CFL is the warmest color available and is closest in color to the incandescent lamp. CFL s are also available in 3000K, 3500K, and 4100K. The 4100K would be the brightest or coolest output. A CFL can be chosen to screw right into your existing fixtures, or hardwired into your existing fixtures. Where the existing fixture is controlled by a dimmer switch, the CFL bulb must be compatible with a dimmer switch. In some Concord Engineering Group, Inc. 9C11001 October 11, 2011 FINAL Page 15 of 33

17 Cherry Hill Twp BOE Cherry Hill High School West Energy Audit locations the bulb replacement will need to be tested to make sure the larger base of the CFL will fit into the existing fixture. The energy usage of an incandescent compared to a compact fluorescent approximately 3 to 4 times greater. In addition to the energy savings, compact fluorescent fixtures burn-hours are 8 to 15 times longer than incandescent fixtures ranging from 6,000 to 15,000 burn-hours compared to incandescent fixtures ranging from 750 to 1000 burnhours. However, the maintenance savings due to reduced lamp replacement is offset by the higher cost of the CFL s compared to the incandescent lamps. Energy Savings Calculations: The Investment Grade Lighting Audit Appendix outlines the hours of operation, proposed retrofits, costs, savings, and payback periods for each set of fixtures in the each building. Rebates and Incentives: From the NJ Smart Start Incentive Appendix, the retrofit of a T-12 fixture to a T-5 or T-8 fixture or the retrofit of existing 32 watt T-8 system to reduced wattage (28w/25w 4') warrants the following incentive: $10 per fixture.

18 Cherry Hill Twp BOE Cherry Hill High School West Energy Audit ECM #2: Lighting Controls Upgrade Occupancy Sensors Description: Some of the lights in the Cherry Hill High School West are left on unnecessarily. In many cases the lights are left on because of the inconvenience to manually switch lights off when a room is left or on when a room is first occupied. This is common in rooms that are occupied for only short periods and only a few times per day. In some instances lights are left on due to the misconception that it is better to keep the lights on rather than to continuously switch lights on and off. Although increased switching reduces lamp life, the energy savings outweigh the lamp replacement costs. The payback timeframe for when to turn the lights off is approximately two minutes. If the lights are expected to be off for at least a two minute interval, then it pays to shut them off. Lighting controls come in many forms. Sometimes an additional switch is adequate to provide reduced lighting levels when full light output is not needed. Occupancy sensors detect motion and will switch the lights on when the room is occupied. Occupancy sensors can either be mounted in place of a current wall switch, or on the ceiling to cover large areas. The U.S. Department of Energy sponsored a study to analyze energy savings achieved through various types of building system controls. The referenced savings is based on the Advanced Sensors and Controls for Building Applications: Market Assessment and Potential R&D Pathways, document posted for public use April The study has found that commercial buildings have the potential to achieve significant energy savings through the use of building controls. The average energy savings are as follows based on the report: Occupancy Sensors for Lighting Control 20% - 28% energy savings. Savings resulting from the implementation of this ECM for energy management controls are estimated to be 20% of the total light energy controlled by occupancy sensors and daylight sensors (The majority of the savings is expected to be after school hours when rooms are left with lights on) This ECM includes installation of ceiling or switch mount sensors for individual offices, classrooms, large bathrooms, and libraries. Sensors shall be manufactured by Sensorswitch, Watt Stopper or equivalent. The Investment Grade Lighting Audit Appendix of this report includes the summary of lighting controls implemented in this ECM and outlines the proposed controls, costs, savings, and payback periods. The calculations adjust the lighting power usage by the applicable percent savings for each area that includes lighting controls.

20 Cherry Hill Twp BOE Cherry Hill High School West Energy Audit ECM #3: Computer Monitor Replacement Description: The computers throughout Cherry Hill High School West utilize a mixture of CRT computer monitors and LCD computer monitors. Computers are located in the offices, computer labs, media centers, and classrooms. The CRT computer monitors are outdated and have several disadvantages such as; significantly increased higher energy consumption, uses large amount of desk space, poor picture quality, distortions and flickering image, secular glare problems, and high weight, and electromagnetic emissions. Many of these drawbacks are difficult to quantify except for the energy use. CRT monitors use considerably more energy than an alternative flat panel LCD monitor. Replacement of the existing CRT monitors with LCD monitors saves considerable energy as well as provides other ergonomic benefits. Based on the site survey it was noted that in some conditions the computers were left on and allowed to run 24 / 7, while in other rooms the computers were shut down. Some of the monitors were left in screen saver mode, which is deceiving since this mode only saves the computer screen from image burn in, however it does not save on energy consumption. The average operating hours for all computers and monitors is estimated based on the site survey observations. Energy consumption of computer monitors is based on manufacture s specifications. This ECM includes replacement of all existing CRT monitors with LCD flat panel monitors throughout the school. Installation costs were neglected for this ECM with the intention that this ECM would be replaced by the school employees. The calculations are based on the following operating assumptions: Energy Savings Calculations: No. of CRT Monitors: 161 Weeks per Yr: 40 Hrs per Week: 60 (12 hrs per day. 5 days per week) # of Electric Usage Computers Monitor Power 1000 W KW W Operation Hrs Energy Cost Electric Usage $ kwh kwh Ave Elec Cost Concord Engineering Group, Inc. 9C11001 October 11, 2011 FINAL Page 19 of 33

23 Cherry Hill Twp BOE Cherry Hill High School West Energy Audit ECM #4: Condensing Boiler Installation Description: The Cherry Hill High School West contains two boiler plants for the entire school. Both plants contain two Cleaver Brooks fire tube gas-fired boilers each that serve the building s heating hot water loops. Two boilers were installed as part of the original construction of the building in 1956 and the other two boilers were installed as part of the 1980 s addition, but all the boilers are years beyond their useful service life as defined by ASHRAE. With the increased efficiency of the condensing boilers, the savings can be substantial. New condensing boilers could substantially improve the operating efficiency of the heating system of the building. Condensing boiler s peak efficiency tops out at 99% depending on return water temperature. Due to the operating conditions of the building, the annual average operating efficiency of the proposed condensing boiler is expected to be 88%.

ADDITIONAL RECOMMENDATIONS The following recommendations include no cost/low cost measures, Operation & Maintenance (O&M) items, and water conservation measures with attractive paybacks. These measures are not eligible for the Smart Start Buildings incentives from the office of Clean Energy but save energy none the less. A. Chemically clean the condenser and evaporator coils periodically to optimize efficiency. Poorly maintained heat transfer surfaces can reduce efficiency 5-10%. B. Maintain all weather stripping on windows and doors. C. Clean all light fixtures to maximize light output. D. Provide more frequent air filter changes to decrease overall system power usage and maintain better IAQ. E. Turn off computers when not in use. Ensure computers are not running in screen saver mode which saves the monitor screen not energy. F. Ensure outside air dampers are functioning properly and only open during occupied mode. G. Educate staff and students on awareness of wasteful energy practices such as leaving lights on unnecessarily, leaving on of non-essential computer and/or equipment at the end of the day, leaving of outside doors/windows open as a means to control room temperature, etc. Concord Engineering Group, Inc. 9C11001 October 11, 2011 FINAL Page 33 of 33
