8 II. FACILITY DESCRIPTION The Christopher Columbus Middle School is located at 350 Piaget Avenue in Clifton, New Jersey. The 83,990 SF Middle School was built in 1929 with a 39,105 SF addition completed in The building is a three story facility comprised of classrooms, offices, cafeteria, auditorium, gym, media center, and mechanical rooms. Occupancy Profile The typical hours of operation for the Middle School are Monday through Friday between 7:00 am and 4:00 pm. Maintenance staff is present in the building as early as 6:00 am. The school s enrollment is approximately 1,216 students, grades 6 th through 8 th, and has 120 teachers, support staff, and administrative personnel. Building Envelope Exterior walls for the middle school are brick faced with a concrete block construction. The amount of insulation within the walls is unknown. The windows throughout the school are in good condition and appear to be maintained. Typical windows throughout the school are double pane, operable, ¼ clear glass with aluminum frames. Some windows, however, are a frosted plastic material. The roof is a flat, EPDM rubber roof on steel decking. The amount of insulation below the roof is estimated to be between 2 to 5 inches. HVAC Systems The middle school HVAC system consists of two hot water boilers, two heating and ventilation units, and unit ventilators in the classrooms. Additionally, there are window mounted air conditioners in various spaces throughout the building. The boilers are gas-fired, cast iron, sectional hot water boilers manufactured by HB Smith. These boilers are 450 mills boilers with 21 sections each. With an input of 6,630 MBH and an output of 4,678 MBH each, these boilers serve the hot water heating coils throughout the facility. Hot water is circulated via eight pumps. There are two 1 HP pumps, one 1.5 HP pump, four 2 HP pumps, and one 5 HP pump that circulate hot water to the various zones in the building. Fresh air is supplied to the building by the unit ventilators in each classroom. These units are capable of heating and ventilation only. They have a hot water coil for heat and a fan to distribute air directly to the space in which they are located. The gym and cafeteria are served by larger heating and ventilation units located in a fan room above the girl s gym. Exhaust System Air is exhausted from the toilet rooms through the roof exhausters. The kitchen has a dedicated exhaust hood system, operated by a disconnect switch. Many of the Art and Shop classrooms had window mounted exhaust fans that were switch operated. May 23, 2013 FINAL Page 7 of 36

9 HVAC System Controls The HVAC Systems within the building are controlled through a pneumatic system. Unit ventilators have pneumatic hot water control valves and thermostats. Domestic Hot Water Domestic hot water for the restrooms is provided by an AO Smith model BC water heater. This heater has an input capacity of 870 MBH. The kitchen dishwasher has a Hatco electric booster heater rated at 45 kilowatts. Lighting Refer to the Investment Grade lighting Audit Appendix for a detailed list of the lighting throughout the facility and estimated operating hours per space. Miscellaneous The kitchen is equipped with one walk-in freezer and one walk-in refrigerator. Each has a dedicated condensing unit located outside on the roof. The kitchen also has one Hobart conveyor style dishwasher model C-44. The kitchen serving line has electric food warmers. The major cooking appliances are gas-fired and some of which are Energy Star Rated. May 23, 2013 FINAL Page 8 of 36

14 ECM #1: Lighting Upgrade General Description: The majority of the interior lighting throughout Christopher Columbus Middle School is provided with fluorescent fixtures with older generation, 700 series and 741/ECO 32W T8 lamps and electronic ballasts. Although these 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. Concord Engineering recommends that most of these fixtures remain unmodified due to the extensive costs which will be incurred if these fixtures are to be re-lamped and re-ballasted which results in a long payback period. For other areas that are over lit, Concord Engineering recommends that the fixture be retrofitted with new Super T-8 lamps/reflector, de-lamped to the appropriate light levels, and a new high-efficiency electronic ballast be installed. This 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. 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. 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. 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 burn-hours. 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.

16 ECM #2: Lighting Upgrade Other Description: The Kitchen, upper and lower gyms and boiler rooms at Christopher Columbus Middle School are currently lit via 400 and 250 watt Metal Halide HID fixtures, and high put T12 fluorescent fixtures. These spaces would be better served with a more efficient, fluorescent lighting system. Concord Engineering recommends upgrading the lighting to an energy-efficient T5 high output system that includes new six, four and two lamp, T5 high output fixtures. This measure replaces all the HID, 400 and 250 watt HID MH fixtures with a well-designed T5 high output (HO) system. Energy Savings Calculations: A detailed Investment Grade Lighting Audit can be found in Investment Grade Lighting Audit Appendix that outlines the proposed retrofits, costs, savings, and payback periods.

17 ECM #3: Lighting Controls Upgrade Occupancy Sensors Description: Some of the lights in the Christopher Columbus Middle School 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 (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 Media Centers. 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.

19 ECM #4: Digital Energy Management System (DDC EMS) Description: Currently, Christopher Columbus Middle School uses a pneumatic control system. This system is very old and offers limited control options for the HVAC systems. Concord Engineering recommends installing a DDC system throughout the school to control all of the HVAC systems including the boilers, indoor air handling units, and roof exhaust fans. The system will include new temperature sensors and new local thermostats with limited override capability, a front end computer and main controller. The system will also include central controls for lighting. With the communication between the control devices and the front end computer interface, the facility manager will be able to take advantage of scheduling for occupied and unoccupied periods based on the actual occupancy of each space in the facility. Due to the fact that the building may have diverse hours of occupancy, including evening and weekend activities, having supervisory control over all of the equipment makes sense. The DDC system will also aid in the response time to service / maintenance issues when the facility is not under normal maintenance supervision, i.e. after-hours. The new DDC system has the potential to provide significant savings by controlling the HVAC systems as a whole and provide operating schedules and features such as space averaging, night set-back, temperature override control, etc. 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 referenced report: Energy Management and Control System Savings: 5%-15%. Savings resulting from the implementation of this ECM for energy management controls are estimated to be 10% of the electricity and 10% for natural gas in these buildings. The basis for the DDC system expansion is the Automated Logic Energy Management System or similar. Energy Savings Calculations: Energy savings for each utility is calculated with the equation below. Energy Savings (Utility) = Current Energy Consumption Estimated Savings, % Following table summarizes energy savings for this facility via implementation of an Energy Management System: May 23, 2013 FINAL Page 18 of 36

The cost of a full DDC system with new field devices, controllers, computer, software, programming, etc. is approximately $546,980 based on recent Contractor pricing for systems of this magnitude. Savings from the implementation of this ECM will be from the reduced energy consumption currently used by the HVAC system by proper control of schedule and temperatures via the DDC system. Currently, there are no prequalified NJ SmartSmart Incentives for installation of the DDC system. May 23, 2013 FINAL Page 19 of 36

22 ECM #5: Condensing Boiler Installation Description: The central heating plant at the Christopher Columbus Middle School consists of two gas fired HB Smith Cast iron sectional boilers. These boilers were built in 1987 and are beyond the 25 year useful service life as prescribed by ASHRAE. These boilers have been maintained well, however, due to their age and overall condition they are good candidates for replacement with newer condensing boilers. 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 92%. The existing boiler s efficiency is approximately 70%, which makes the condensing boilers an 22% increase in efficiency. This ECM is based on variable supply water temperature adjusted based on outdoor temperature. This ECM includes installation of four condensing gas fired boilers to replace the existing boilers, as well as any necessary piping and natural gas service modifications. The basis for this ECM is Aerco condensing boiler; model number BMK 2.0. The boiler installation is based on a one for one replacement based on capacity of the existing boiler.

25 ECM #6: Install NEMA Premium Efficiency Motors Description: The improved efficiency of the NEMA Premium efficient motors is primarily due to better designs with use of better materials to reduce losses. Surprisingly, the electricity used to power a motor represents 95 % of its total lifetime operating cost. Because many motors operate continuously 24 hours a day, even small increases in efficiency can yield substantial energy and dollar savings. The electric motors driving the hot water pumps are candidates for replacing with premium efficiency motors. These standard efficiency motors run considerable amount of time over a year. This energy conservation measure replaces existing inefficient electric motors with NEMA Premium efficiency motors. NEMA Premium is the most efficient motor designation in the marketplace today.

28 ECM #7: Variable Speed Drive for Air Handling Units Description: The existing gym and cafeteria air handling units supply heated and tempered air to their respective spaces. It was noted at the time of survey that many of the air grilles were not properly cleaned and had excessive amounts of dust surrounding the terminal. In order to correct this problem and reduce the energy consumption of the supply fan a variable speed drive should be installed on the units. The drive will be controlled off a duct mounted static pressure sensor. Energy Savings Calculations: Variable Speed Drive (VSD) savings were calculated with an Excel Spreadsheet using the Affinity Laws (see Appendix G). It was assumed that the fan operates continuously for 3,000 hours per year as suggested by the schedule provided by the owner. The percentage of load for the fan was considered to be at 80% load for 65% of the time, 90% load for 20% of the time, and 100% load for 15% of the time.

32 ECM #9: Window AC Unit Replacement Description: Cooling is provided to several classrooms via window air conditioning units. These units vary in size, capacity and efficiency. The units have been fixed or replaced on an as needed basis throughout the building. Some of these units are old and inefficient. It is recommended to utilize the energy star ratings as a minimum standard for replacing any window unit that is in need of replacement. Existing units that are old but still working should be considered for replacement if the efficiency is below 8.0 to 8.5 EER. Window AC units that are over 10 years old are very likely to fall in this efficiency range. This ECM shows the savings and payback for replacing inefficient window air conditioners with new, Energy Star rated units. Qualifying product list can be found at Energy Star website at: Although energy star rated products provide a valuable benchmark, it is recommended to consider even higher EER ratings for potential AC unit replacements where available.

34 ECM #10: Occupancy Controlled Power Strips Description: Plug loads in buildings are increasingly becoming a majority share of electrical consumption annually as HVAC and lighting technologies are becoming more efficient and more energy is being utilized other equipment. The Christopher Columbus Middle School has approximately two-hundred (200) computers used by staff and students. During the survey it was noted that many of these computers were on and operating while no one was using the work station. To reduce idle power draw load from the computer and peripheral equipment while not in use, CEG recommends the installation of Watt Stopper IDP-3050 occupancy controlled power strip. The power strip has the same features of a typical strip except it is fitted with an infrared occupancy sensor. The sensor reads when an occupant is using their workstation and insures all equipment is fully powered, however when an occupant is not present the strip shuts power off to devices plugged into the control outlets of the strip. Installing these power strips could substantially reduce energy waste due to plugged in equipment. The intent of this ECM is to provide control of ancillary devices such as computer monitors, speakers, printers, task lights, and etc. that can be shut off by the control outlets when the user is not present. Energy Savings Calculations: The manufacturer has estimated that typical savings for their power strip can save 75 kilowatthours per work station or more.

37 V. 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. While the District is already performing many of these functions through routine maintenance it is important to continue to address these items as they provide an energy savings benefit. 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. F. Replace older style CRT monitors with newer energy efficient LCD/LED monitors. G. Ensure classroom televisions are turned off at the end of the day and while not in use. H. Ensure outside air dampers are functioning properly and only open during occupied mode. May 23, 2013 FINAL Page 36 of 36
