II. FACILITY DESCRIPTION

The Howell Township Newbury Elementary School is located on 179 Newbury Road in Howell, New Jersey. The Elementary School was built in 1964 with an addition in 1973 and in 1989. The facility has a total square footage of 79,850 SF. The Elementary School consists of classrooms, offices, gymnasium, an auditorium and cafeteria.

Occupancy Profile

The typical hours of operation for the Elementary School are Monday through Friday from 8:45 am to 3:15 pm for students but further occupancy occurs from 3:15 pm to 11:00 pm for cleaning. The Elementary School employs approximately 73 people, with student enrollment estimated to be around 395.

Building Envelope

Exterior walls for the Elementary School facility are a 4” brick. The exterior wall assembly consists of 4 inches of brick, 2 inches of cavity and 6 inches of concrete block. The amount of insulation within the walls is not known. The windows throughout the School are in good condition and appear to be well maintained. Typical windows throughout facility are double pane, ¼” tinted glass with aluminum frames. Some sections of the school, such as hallways and entrances, have single pane, ¼”, un-insulated glass windows.

The roof is a flat built up roofing system with a light stone covering. The amount of insulation below the roofing is unknown.

HVAC Systems

The boiler plant section consists of two (2) H.B Smith cast iron sectional boilers. The boilers are both gas-fired. Both boilers have an input raring of 4,258 MBH and output rating of approximately 2,930 MBH with an estimated efficiency of 75%. These boilers were installed approximately 24 years ago (based on model and condition), and appear to be replacements to the original building boilers. These boilers are within their ASHRAE recommended service life and are in good condition. Newer, high efficiency condensing boilers would provide superior operating efficiency over the existing boilers making these boilers candidates for replacement.

Hot water is circulated throughout the building’s heating hot water loop via two (2) base mounted end suction pumps. These pumps have 7-1/2 HP motors and appear to be original to the building. The motors, however, appear to be replacements. These motors are standard efficiency and are ideal candidates for replacement.

The classrooms of the school are served by perimeter unit ventilator units. These units are heating and ventilation only and have hot water coils controlled by two-way valves and wall mounted thermostats.

The multi-purpose room is served by a roof mounted hot water H&V unit. This unit provides outside air and heating to the space. This unit is a McQuay model and is equipped with a hot water coil and three-way control valve.



The Media Center, Computer room, Music room and band rooms are each served by packaged rooftop air conditioning units with cooling only capabilities. These units are all McQuay models and vary in size. These units all appear to have been installed at the same time and range in size from 3-1/2 Tons up to 16 tons.

The Cafeteria and Kitchen are served by indoor heat only air handling units. These units provide heating and ventilation air to their respective spaces.

The Nurse’s office and main office are each served by a packaged rooftop cooling only air conditioning unit. These units are each approximately 23 years old and have surpassed their useful service life.

Exhaust System

Air is exhausted from classrooms and toilet rooms through the roof mounted exhaust fans.

HVAC System Controls

The HVAC systems throughout the facility are controlled via vintage electronic controls, manufactured by Barber Coleman. The building equipment (Unit ventilators, exhaust fans, H&V units) operational status (on/off) are controlled through a switchboard, located in the boiler room. These controls operate based on a time clock. Individual space temperature is controlled via wall mounted thermostats.

The packaged rooftop units each have their own individually controlled space thermostat. The T-Stats in the main office and nurse’s office are 7-programmable Honeywell thermostats.

Domestic Hot Water

Domestic hot water is provided by an A.O. Smith, condensing style hot water heater. The water heater is rated for 399.9 MBH input with an overall efficiency of up to 95%. This unit is in excellent condition and is within the ASHRAE recommended service life. 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.

ECM #1: Lighting Upgrade – General Description: The majority of the interior lighting throughout Newbury Elementary School is provided with fluorescent fixtures with older generation, 700 series 32W T8 lamps and electronic ballasts. While newer, 800 series 28W T8 lamps would be more efficient, field survey of the existing ballasts revealed that they are not rated for 28W lamps. The gymnasium is currently lit via forty two HID, 400W, Metal Halide fixtures. The space would be better served with a more efficient, LED lighting system. CEG recommends upgrading the existing lighting to energy efficient, 93 Watt LED lamps. These lamps can be retrofitted within the existing MH fixture, reducing the overall cost of the replacement. This ECM includes re-lamping of the existing HID fixtures with the 93 Watt LED 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. Currently, there are no Smart Start incentives for re-lamping of existing fixtures. Energy Savings Summary:

ECM #1 - ENERGY SAVINGS SUMMARY



ECM #2: Lighting Controls Upgrade – Occupancy Sensors Description: Some of the lights in Newbury Elementary 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 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 (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. Energy Savings Calculations:

ECM #3: Boiler Systems Upgrade – Condensing Boilers Description: Space heating for Newbury Elementary School is provided by a heating hot water loop. The source of hot water for this equipment is two cast iron sectional hot water boilers located in the boiler room. The output capacity of each boiler is 2,930 MBH. The boilers were installed approximately 24 years ago, which brings them close to their ASHRAE service life. The units are still in service and are in fair condition, however it is recommended that at least one boiler be replaced with newer high efficiency units. This ECM provides insight into the energy efficiency benefit of condensing boiler technology compared to standard cast iron boilers. Standard (non-condensing) boilers provide lower than nominal efficiency compared to condensing boilers. Standard boilers suffer further efficiency losses at part load operating conditions mainly due to limitations in the reduction of the flue gas temperature. Current average combustion efficiency of each boiler is estimated to be 70% due to standard non-condensing boiler technology, limited turn down ratio, cycling losses and outdated design and controls. A new condensing boiler 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. This ECM is based on the replacement of one of the hot water boilers with two (2) Aerco Benchmark 2.0 modular condensing boilers. This would allow the remaining boiler to act as a backup. Since the boilers currently installed operate as primary and standby, installing two boilers that would run at part load would result in less runtime at full load, compared to the existing boilers. The annual average operating efficiency of the proposed boiler set is expected to be 90%, which gives the heating system a 20% increase in efficiency. This ECM is based on variable supply water temperature adjusted based on outdoor temperature. The owner is recommended to retain a professional engineer to confirm equipment sizing and finalize design.

BOILER REPLACEMENT SUMMARY



First, domestic hot water usage is estimated and subtracted from the total usage in order to estimate the net natural gas usage for space heating. It should be noted that the off-heating season (May thru September) gas usage is higher than normal. It is unclear what the cause of this usage is, but it is assumed that the boilers are operating year round. For the purpose of this calculation, we have assumed that the average off season gas usage is used by the domestic hot water heater. Current total hot water usage can be found in the table below:

ECM #4: RTU Upgrades

Description:

The main office, nurse’s office, Media Center, computer room, music room and band room of Newbury Elementary School are air conditioned by six (6) packaged rooftop units ranging insize from 3-1/2 Tons up to 16 Tons. These units are in fair to poor condition and have surpassed their useful ASHRAE service life. The units currently installed are less efficient compared to modern equipment and can be replaced with new high efficiency units. New air conditioners provide higher full load and part load efficiencies due to advances in inverter motor technologies, heat exchangers and refrigerants. This ECM includes one-for-one replacement of the old air conditioning units with new higher efficiency systems. 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 replacements for this ECM can be found in the table below:

The manufacturers used as the basis for this calculation is Carrier. Units are one for one style replacements with matching capacity of the new units to the old units. The unit pricing and install cost were estimated based on current rates. The payback may change based on actual unit pricing and install costs if the ECM is implemented.

ECM #5: Install Unit Ventilators with Energy Recovery Description: The heating and air conditioning for the classrooms in the School are provided by a combination of Nesbitt, American Air Filter (AAF) and McQuay unit ventilators, all varying in age. Some of the units have had control upgrades/replacements; however, they have all surpassed their expected useful service life, which is fifteen (15) years per ASHRAE. The estimated total number of older unit ventilators in the school is 34. The units are heating only and controlled with electronic controllers and actuators. It is recommended to replace older unit ventilators with modern unit ventilators with energy recovery wheels. The advantage of this setup is the utilization of the energy recovery system to recover the energy in the exhaust air in order to reduce the heating and cooling demand of the classrooms. This ECM replaces existing 34 older unit ventilators with new unit ventilators with hot water heating coils and built-in energy recovery wheels. The basis for this ECM is Trane HUVC series unit ventilator with corresponding Energy Recovery ventilators. The ECM also includes attaching the unit ventilator controls to the Building Energy Management System (ECM#10) to achieve superior scheduling and controls. Energy Savings Calculations: The energy savings calculations are based reduction of the outside air heating, reduction of the overheating and infiltration due to opening of the windows and temperature setback during nights and weekends. Nominal recovery capacity of the proposed unit is calculated based on typical outside air percentage, heating degree days and design day temperature difference. Total energy recovery of each unit at heating modes is calculated using heating degree days:

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. Due to the fact that many motors operate continuously 24 hours a day, even small increases in efficiency can yield substantial energy and dollar savings. The school has two motors that are candidates to be replaced with NEMA Premium® efficiency motors. These motors are located in the boiler room which serves the hot water loop and zone loops. Boiler operating hours were estimated based on hours of operation obtained from the school. The pumps operate in parallel, which means these pumps operate simultaneously. This energy conservation measure replaces the existing lower efficiency electric motors with NEMA Premium® efficiency motors. NEMA Premium® is the most efficient motor designation in the marketplace today. The energy savings and payback are subject to change based on the pool filtration usage during the year. An implementation summary of the motor is provided below.

ECM #7: Install HW Pump VFD’s Description: The heating and ventilation units and the unit ventilators are utilizing a constant volume pumping design. 2-way control valves provide flow through the heat exchanger equipment only when there is a call for heating or cooling, unlike 3-way control valves that allow constant flow of the water loop. 3-way control valves require full pumping energy continuously, while 2-way control valves allow the system to reduce flow when it is not needed. This measure includes capping off the bypass port on the 3-way control valves which effectively turns the valves into “2-way” control valves. When the unit is not calling for heating, the control valve closes reducing overall flow of the system. Variable frequency drives allow the pumps to slow down in response to a reduction in overall system flow. The reduction in operating flow allows the pumps to reduce energy consumption for all hours that the heating system is not at its peak load. This ECM includes the installation of Variable Frequency Drives on the two (2) existing pumps within the boiler room. To control flow through the system, this ECM includes piping modifications at the H&V units, and unit ventilators to cap off the bypass port on the 3-way control valves. The VFD’s would be controlled by a differential pressure sensor in the water loop to measure demand for water (typical for each of the three pump sets). The furthest unit from the loop pumps would remain as 3-way control valves (constant flow) to eliminate dead heading potential. This ECM also includes replacement of the existing pump motors with inverter duty motors that meet NEMA Premium Efficiency Standard, which also helps to reduce energy consumption. CEG recommends that this ECM be implemented in conjunction with ECM#6, replacement of the existing hot water pump motors with inverter duty motors that meet NEMA Premium Efficiency Standard. Implementation of both measures will further reduce energy consumption. Energy and cost savings calculations are based on calculation software “PumpSave v4.2,” provided by ABB. The PumpSave calculation software is used to estimate the pumping energy for variable speed pump systems. The boiler water loop pumps operate approximately 4,320 Hrs per year since this system is used for about 6 month’s total. The pump flow, HD, and resultant energy are calculated based on the existing pump horse power installed. The calculation is based on all existing equipment to be modified to operate as 2-way control valves. Where control valves are already 2-way style, these control valves shall remain. The exact quantity of equipment with hot water coils is unknown. The operation of all equipment control valves should be verified before implementing this ECM. Energy Savings Calculations:

ECM #8: Demand Controlled Ventilation – Cafeteria Demand Controlled Ventilation (DCV) is a means to provide active, zone level control of ventilation for spaces within a facility. The basic premise behind DCV is monitoring indoor CO2 levels versus outdoor CO2 levels in order to provide proper ventilation to the spaces within the facility as well as saving costly dollars treating unconditioned ventilation air. Carbon dioxide ventilation control or demand controlled ventilation (DCV) allows for the measurement and control of outside air ventilation levels to a target cfm/person ventilation rate in the space (i.e., 15 cfm/person) based on the number of people in the space. It is a direct measure of ventilation effectiveness and is a method whereby buildings can regain active and automatic zone level ventilation control, without having to open windows. The fixed ventilation approach depends on a set-it-and-forget-it methodology that is completely unresponsive to changes in the way spaces are utilized/occupied or how equipment is maintained. A DCV system utilizes various control algorithms to maintain a base ventilation rate. The system monitors space CO2 levels and the algorithm automatically adjusts the outdoor and return air dampers to provide the quantity of outdoor air to maintain the required CO2 level in the space. System designs are normally designed for maximum occupancy and the ventilation rates are designed for this (maximum) occupancy. In areas where occupancy swings are prevalent there is ample opportunity to reduce outdoor air quantity to satisfy the needs of the actual number of occupants present. By installing the DCV controls, energy savings are realized by the reduced quantities of outdoor air that do not require heating and cooling energy from the steam and chilled water plants. There are two (2) heating and ventilation units that serve the Cafeteria. When operating, this unit provides minimum amount of outside air to the space. The outside air volume is typically based on the maximum occupancy of the space conditioned. When a given space is not fully occupied the outside air quantity delivered to the space is greater than the amount needed for adequate ventilation. This ECM includes the installation of CO2 sensors integrated into a demand control ventilation system, for the unit mentioned above. This system allows the air handling unit to respond to changes in occupancy and therefore reduce the amount of outside air that has to be conditioned. Outside air accounts for a large portion of the energy consumption in the HVAC system, especially in high occupancy spaces. The components required for the demand control ventilation system installation include damper actuators, Variable Frequency Drives, CO2 sensors, wiring, Energy Management System equipment expansion and programming. Each occupied zone would require minimum one CO2 sensor installed to monitor occupancy levels. Often heating and air conditioning units switch to occupied mode several hours before the actual occupancy in order to provide pre-heating or pre-cooling of the space. Energy savings achieved through “Demand Control Ventilation” is calculated based on actual occupancy of the spaces and the hours the units are in occupied mode.

ECM #9: Valve Blanket Insulation

Description: The boiler plant supplies heating hot water to the facility for heating season. The piping remains heated at approximately 180°F continuously during this period (approximately 6 months). Un-insulated piping and valves have significant heat losses due to the exposure of the steel piping to the surrounding air. Insulated piping has a heat loss which is a small fraction of the heat loss from un-insulated piping. It was noted that numerous valves throughout the system were un-insulated. Valve blankets are designed to provide insulation value over large hydronic valves that must remain accessible. This ECM includes installation of valve blankets on all exposed boiler system valves within the boiler room. Energy Savings Calculations: Heat Loss for un-insulated steel piping is based on ASHRAE 2009 Fundamentals – “Insulation for Mechanical Systems” Bare Steel Piping Heat Loss 6” pipe: 373 BTU/HR per Linear FT

ECM #10: DDC Controls Upgrade Description:

Newbury Elementary School is currently controlled primarily through the use of vintage electronic control systems. CE recommends installing a central DDC system to control the HVAC systems in the school including the air handling units, unit ventilators, wall thermostats, air conditioning units, rooftop units, boilers and pumps. The addition of DDC control systems will allow easier, and remote operation for building facility management personnel. This ECM includes installation of a Building Automation system to include control of the majority of the HVAC equipment in the facility. The system will include new temperature sensors and new local thermostats with limited over-ride 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 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 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 the gas utility in this building.

The basis for the DDC system expansion is the Automated Logic Energy Management System or similar. Energy Savings Calculations: Since some of the key utility consumption and cost information was not available, estimated values are used for the unit cost of natural gas, total electricity usage and unit cost of electricity.

Energy savings for each utility is calculated with the equation below.

ECM #11: Water Efficiency & Conservation Description: The facility utilizes standard plumbing fixtures. The typical water closet and urinal water consumption only meet the minimum federally required standard for water efficiency. New fixtures are available that use less water than today’s requirements and can add up to significant water reduction over a long period. This ECM includes the replacement of the existing sink faucets, water closets and urinals within the bathrooms the facility. The estimated usage of the plumbing fixtures is based on the total population of the facility. The proposed retrofit includes installation of auto flow sink faucets, low flow aerators, low flow flushometer style water closets that utilize 1.28 gallons per flush and ultra-low flushometer style urinals that utilize 1/8 gallons per flush. For the basis of this calculation the LEED rating system was used to estimate the occupancy usage for students within the school. When water consumption information was not available, the GPF values were estimated for the existing fixtures. Energy Savings Calculations: Urinals and Toilets:

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 systempowerusage 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.
