II. FACILITY DESCRIPTION

The William Paterson University, Cheng Library is a 102,634 SF Public Library was built in 1965 with renovations done in 1995. The building is a two story facility with a basement and penthouse mechanical room and consists of group study rooms, book stack areas, conference rooms, lecture hall, and utility rooms.

Occupancy Profile

The typical hours of operation for the Cheng Library are Monday through Thursday between 8:00 am and 9:00 pm, Friday and Saturday between 8:00 am and 5:00 pm. The Cheng Library’s occupancy can vary during the day. The library employs 54 people.

Building Envelope

The exterior walls for the Cheng Library are brick faced with a concrete block construction. The amount of insulation within the walls is approximately ¾” foam insulation. The windows throughout the Cheng Library are in good condition and appear to be maintained. Typical windows throughout the Cheng Library are single panel, without exterior shading. The roof is a flat, built up rubber roof where the AC units reside as well as the Cooling Towers. The amount of insulation below the roofing ranges from 2” to 5” depending on the location of the roof.

HVAC Systems

The Cheng Library system consists of two (2) hot water boiler, two (2) Water Chillers with its respective Cooling Tower, and six (6) Air handling units.

The boilers are two (2) gas-fired condensing hot water boilers with an input of 2,000 MBH and an output of 1,706 MBH. The units were manufactured by Aerco and have a boiler efficiency of 85%. These boilers were installed last year (based on the model and serial number) and they look in good conditions.

Hot water is circulated throughout the building’s heating hot water loop via two (2) base mounted end suction pumps. These pumps have 25 HP motors with a flow rating of 800 GPM at 95 foot of head pressure and were installed during the renovation done in 1995. The motor efficiencies of the pumps are 89.5% and look in good conditions under the ASHRAE recommended service life. These pumps are also fit with variable speed drives.

The Chillers are two (2) McQuay Centrifugal Water-cooled Chillers with a cooling capacity of 250 Tons each and an efficiency of 0.62 kW/ton. These units were installed in 2011.

Chiller water is circulated throughout the building via two (2) base mounted end suction pumps. These pumps have 50 HP motors with a flow rating of 1000 GPM at 100 foot of head pressure and were installed during the renovation done in 1995. The motor efficiencies of these pumps are 89.5%. These pumps are also fit with variable speed drives.

The Cooling Tower model NC3022GS is manufactured by Marley. This unit serves the Water-cooled Chillers located in the lower Lever MER and it is within its ASHRAE recommended



service life. The unit is fitted with a 20 horsepower fan motor and does not have two speed or variable speed controls.

Condenser water is circulated from the cooling tower to the chillers via two (2) base mounted end suction pumps located in the Lower Level MER. These pumps have 40 HP motors and were installed during the renovation done in 1995. The motor efficiencies of these pumps are 89.5% and are within the ASHRAE recommended service life. These pumps are also fit with variable speed drives.

The Library is conditioned by six air handling units, two located indoor and four on the roof. The four roof top air handlers (AHU-1 to 4) are cooling only units with chilled water coils and condition the perimeter spaces on the first and second level. Units 1 to 4 feed into variable air volume terminal boxes with hot water reheat coils. The two indoor units (AHU-5 &6) condition mainly the core space on levels 1 and 2. These units have chilled water and hot water coils and supply variable air volume terminal boxes that distribute to multiple zones.

Exhaust System

Air is exhausted from the toilet rooms through the roof exhausters. The Exhaust Fans are located on the roof and were operating during survey.

HVAC System Controls

The HVAC systems within the Cheng Library are controlled through non-programmable thermostats. A time clock controls which thermostat is utilized based on the occupancy schedule. Currently, the Cheng Library is one of the buildings controlled via the building management system in the Facility Management Building. Occupied modes are set for the same hours of operation in that 8:00 am to 9:00 pm from Monday to Thursday and 8:00 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 DDC system is manufactured by Andover

The boilers are operated based on outside air reset controller from Aerco’s controller with the BMS System. A three way control valve modulates the flow of the boilers into the loop based on an outside sensor. The primary boiler loop runs continuously.

Domestic Hot Water

Domestic hot water is provided by a 75 gallon gas fired hot water heater with an input capacity of 75 MBH. The DHWH is located in the Lower Level MER manufactured by Rheem Ruud. This unit was installed three years ago and is under ASHRAE recommended service life.

ECM #1 - ENERGY SAVINGS SUMMARY



ECM #2: Vending Miser Controls Description: The Cheng Library has two vending machines located one snack and one cold beverage. These machines run continuously throughout the day even though they are sporadically used. 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.

ECM #3: Install VFD on Cooling Tower Fan Description: The Cooling Tower for the Cheng Library is an older Marley Tower with a constant volume fan. The tower is a single cell with one fan, and was originally sizes for use with an absorption chiller that has not been upgraded to an electric centrifugal. The installation of a VFD will allow the tower fan to modulate based on the required amount airflow needed to maintain the necessary condenser water temperature for the chiller. This ECM includes the installation of a variable frequency drive and inverter duty premium efficiency motor on each tower fan along with the required tower controls to modulate the fan speed. It should be noted that the tower is near the end of its useful life and while retrofitting the tower is more cost effective then replacing the entire tower, the University should consider replacement of the tower as an alternative option. A new tower should greatly reduce make up water consumption and improve chiller performance. Energy Savings Calculations: Load Factor = 75% (without VFD)

ECM #4: 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.

After review of the facility’s existing thermal load and resultant high summer thermal usage, it was determined that 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 building space heating/reheating. The installation will include the necessary heat exchangers, electrical interconnection equipment, and radiator. Energy Savings Calculations:

ECM #5: Lighting Upgrade Description: There are still some areas in the Cheng Library utilizing older T12 fluorescent technology and incandescent style lamps. By upgrading these lamps to newer more efficiency fluorescent and compact fluorescent technology a significant reduction in energy can be realized for these fixtures. This ECM replaces the existing incandescent down lights in the Auditorium and 2x2 recessed T12 fixtures located in the Men’s and Women’s Restroom.

ECM #6: Lighting Controls Description: Many of the areas of the facility utilize standard wall mounted switches to control the operation of lights, resulting some of the lights in the building being 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 study rooms, labs, lounge, and administrative offices. 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.

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. 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.
