II. FACILITY DESCRIPTION

The Wightman Gym is a 47,001 SF athletics facility built in 1960 with no renovations. The building is a two story facility with a basement comprised of gym spaces, pool, mechanical room, offices, and classrooms.

Occupancy Profile

The typical hours of operation for the Wightman Gymnasium are Monday through Thursday between 8:00 am and 9:00 pm, Friday and Saturday between 9:00 am and 5:00 pm. The Wightman Gym occupancy can vary during the day and this specific facility employs 22 people.

Building Envelope

The exterior walls for the Wightman Gym are brick faced. The amount of insulation within the walls is approximately ¾” foam insulation. The windows throughout the Wightman Gym are in good condition and appear to be maintained. Typical windows throughout the Wightman Gym are double pane, operable, ¼” clear glass with aluminum frames. . The roof is a flat, built up rubber roof where the HVAC equipment resides. The amount of insulation below the roofing ranges from 2” to 5” depending on the location and slope of the roof.

HVAC Systems

The Wightman Gym system consists of seven (7) hot water boilers, four (4) Air conditioning units, one (1) roof top unit and three (3) Heating & Ventilator units.

The boilers are gas-fired condensing hot water boilers with an input of 2,000 MBH and an output of 1,706 MBH. The boilers are manufactured by Aerco and have a boiler efficiency of 86%. These boilers serve the unit ventilators which run throughout the perimeter of the building. The boilers also serve the domestic hot water system, pool heating, and the hot water coils within the Heating & Ventilator units located in the attic. These boilers were installed nine years ago and operating within their ASHRAE recommended service life and are in good condition.

Hot water is circulated throughout the building’s heating hot water loop via eight (8) inline end suction circulating pumps. From the eight (8) pumps, P-7 & P-8 alternate run time for domestic hot water, Pumps P-9 & P-10 circulate pool heating water, and pumps P-1 to P-6 alternate operation for space heating hot water. These pumps have horsepower rating from 2 to 10. The circulating pumps are installed 4 years ago and appear to be in good condition.

The HV units manufactured by Trane serve the Gym and are located in the Attic. These units provide outside air and heating to the space. Each unit is equipped with a hot water coil and three way control valve. The HV units are over the ASHRAE recommended useful life and are good candidates for replacement. These units will be improved by new equipment with better operating efficiency.

The AC units are manufactured by York and only provide cooling throughout the office section of building. The Cooling Capacities of the AC units are from 4 to 12.5 Tons and are charged by Refrigerant R-22. These units were installed 20 years ago and are well past their useful service



life per ASHRAE. The only RTU manufactured by AAON is located on the lower roof level and has a cooling capacity of 4 tons. This unit (RTU-1) has included a cooling unit and a Central Furnace with a Heating input of 90 MBH supplied by natural gas. This unit is under ASHRAE recommended useful life and is in good condition.

The unit ventilators located in the Classrooms 202 & 203 are being served by the Gas-Fired hot water boilers. These units are currently defected and their function is trying to be replaced by electrical AC windows.

Exhaust System

Air is exhausted from the toilet rooms through the roof exhausters. The Gym Exhaust System is being served by four (4) EF units in the Attic above the Gym. These units are manufactured by Trane and are over useful life recommended by ASHRAE. These units are good candidate for replacement.

HVAC System Controls

Individual spaces temperature within the Wightman Gym is controlled through wall mounted thermostats. The Wightman Gym is one of the buildings controlled via vintage electronic controls, manufactured by Andover. The building equipment (unit ventilators, exhaust fans, H&V units) operational status (on/off) are controlled through a switchboard, located in the boiler room. Occupied modes are set for the same hours of operation in that 8:00 am to 9:00 pm from Monday to Thursday and 9:00 am to 5:00 pm on Friday and Saturday, the temperature set-points are approximately 72°F for cooling and 70°F for heating in occupied with roughly a 10 degree setback during unoccupied. The outside air is shut off from the building during unoccupied periods. The room set points are approximately 72°F for cooling and 70°F for heating.

Domestic Hot Water

Domestic hot water is provided by one (1) Indirect Fired Tank manufactured by Alfa Laval. The DHWH is located in the boiler room and the Domestic Hot water is circulated via two (2) Inline End Suction pumps. These pumps (P-9 & P-10) have 2 HP motors and have 2 minutes off delay run time after the call to run is removed.

ECM #1: Replace AC Unit with High Efficiency Unit

Description:

The Wightman Gym Facility has four (4) AC units. The cooling capacities range from 4 to 13 Tons. These units are in good condition; however the current units in operation are not high efficiency units when compared to a modern unit. New condensing units provide higher full load and part load efficiencies due to advances in inverter motor technologies, heat exchangers and higher efficiency refrigerants such as R410A which would be used in place of R22 that is currently used in the units. This ECM includes one-for-one replacement of the older units with a new higher efficiency system. It is recommended to fully evaluate the capacity needed for all new systems prior to moving forward with this ECM. A summary of the unit replacement for this ECM can be found in the table below:

ECM #2: Install NEMA Premium® Efficiency Motors Description: Three (3) Heating and Ventilator units and hot water heating pump motors can be replaced with improved efficiency of the NEMA Premium® efficient motors 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. This energy conservation measure replaces existing inefficient electric motors with NEMA Premium® efficiency motors of 2 to 10 HP. NEMA Premium® is the most efficient motor designation in the marketplace today. IMPLEMENTATION SUMMARY

ECM #3: Pool Cover Description: The Pool is used throughout the year at the University however there is still a significant amount of time when the pool area is unoccupied. While the pool is occupied and unoccupied evaporation occurs from the pool to the space resulting in heat loss and water loss. As the evaporation occurs the buildings boiler system and domestic water system make up for the losses heat and water. Over the course of a year these losses add up to almost 70% of the operating cost of an indoor pool. This ECM recommends installing a pool cover that used during unoccupied periods to reduce the evaporation rate. This measure includes the purchasing of the cover and roller. Energy Savings Calculations: Savings are calculated based using the Shah described in “Calculating Evaporation from Indoor Water Pools” (Shah, 2004). Based on DOE data pool covers can save anywhere from 25% to 50% of the evaporative losses during unoccupied times. Water savings were also estimated for this ECM based on an estimated water rate of $5.00 per 1,000 gallons.

ECM #4: Vending Miser Controls Description: The Wightman Gym currently has vending machines in the reception areas for the Wightman Gym which can be in use for a limited time during the day. The installation of the Vending Miser system will help reduce the operating hours of vending machines. Cold beverage machines regularly operate inefficiently trying to maintain a constant cool temperature within the machine and snack machines with no cooling usually have lights that operate 24/7. The VendingMiser® system incorporates innovative energy-saving technology into a small plug-and-play device that in conjunction with a passive infrared sensor regulate the operation of the cold beverage and snack machines based on occupancy and room temperature. This ECM approximates the installation of two (2) of these control systems, one (1) for the snack machines and one (1) for the cold beverage machines. Energy Savings Calculations: See Vending Miser Appendix for calculation methods and analysis. Energy Savings Summary:

ECM #5: 100 kW Combined Heat and Power Description: Combined heat and power, or cogeneration is the simultaneous production of two useful forms of energy (electricity and thermal) from a single fuel source. The standard CHP system is comprised of a prime mover (reciprocating engine or turbine generator) and a heat recovery unit. The heat recovery unit utilizes the waste and exhaust heat from the prime mover to produce hot water or steam. The hot water or steam can in turn be utilized to produce chilled water. In some cases the prime mover exhaust can be directly vented into an absorption chiller, which will produce chilled water without the need for a heat recovery unit.

Depending on the design and application CHP systems can have total efficiencies of 70% to 90%. This is much higher than the traditional utility grid generation with simple cycle generators (25% to 45%) and combined cycle power plants (50% to 60%) due to the more complete utilization of the exhaust and/or waste heat from the prime mover. The higher efficiency of CHP can result in significant energy cost savings. In addition the higher fuel efficiency results in lower emissions per unit of power produced compared to traditional electrical and steam generating units.

The efficiency and cost savings of CHP systems depend on the complete use of the exhaust thermal energy from the prime mover. The economics of CHP are very sensitive to the thermal energy production and consumption. If the prime mover exhaust thermal energy cannot be completely used, the system efficiency is reduced, which will negatively impact the project lifecycle cost and payback. Therefore when examining a potential CHP system it is important to consider the thermal load profiles first and then review the electrical profiles.

Based on review of the existing facilities thermal load and the year round nature of the pool load it was determined that only a small combined heat and power plant could be installed on site that would operate at peak efficiency. The analysis assumes the plant will operate year round at a 92% availability, which takes into account periodic downtime for maintenance. Based on the load information we recommend the installation of one TeCogen 100 kW engine. The proposed plant will recover the waste engine heat and utilize it for domestic hot water, building space heating, and pool heating. The installation will include the necessary heat exchangers, electrical interconnection equipment, and radiator. Energy Savings Calculations: See Appendix for Combined Heat and Power Analysis. Incentives for this measure are based on current NJ Clean Energy CHP Incentive Program.

ECM #6: Lighting Controls Description: While many of the areas of the facility utilize occupancy sensors to control the operation of lights, some of the lights in the building 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 2005. 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. This ECM includes installation of ceiling or switch mount sensors for the weight room, auxiliary gym, offices, locker rooms, and classroom. 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. Energy Savings Calculations:

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 but save energy none the less.

A. Install sub metering equipment to track electric usage for this facility.

B. Small Lighting Upgrade See Appendix E for three (3) T12 fixtures to be retrofitted and one (1) LED Exit Sign.

C. Chemically clean the condenser and evaporator coils periodically to optimize efficiency. Poorly maintained heat transfer surfaces can reduce efficiency 5-10%.

D. Maintain all weather stripping on windows and doors.

E. Clean all light fixtures to maximize light output.

F. Provide more frequent air filter changes to decrease overall system power usage and maintain better IAQ.

G. Ensure outside air dampers are functioning properly and only open during occupied mode.
