There may be energy procurement opportunities for the Hardyston Township Middle School to reduce annual electricity utility costs, which are $17,295 higher, when compared to the average estimated NJ commercial utility rates. SWA has entered energy information about the Hardyston Township Middle School in the U.S. Environmental Protection Agency‘s (EPA) ENERGY STAR® Portfolio Manager energy benchmarking system. This facility is categorized as a K-12 School space type. The Hardyston Township Middle School has a national energy performance rating of 28. The Site Energy Use Intensity is 109 kBtu/sqft/yr compared to the national average of a K-12 School building consuming 90 kBtu/sqft/yr. Based on the current state of the building and its energy use, SWA recommends implementing various energy conservation measures from the savings detailed in Table 1. The measures are categorized by payback period in Table 2 below:

Table 2: Energy Conservation Measure Recommendations

ECMs First Year

INTRODUCTION Launched in 2008, the Local Government Energy Audit (LGEA) Program provides subsidized energy audits for municipal and local government-owned facilities, including offices, courtrooms, town halls, police and fire stations, sanitation buildings, transportation structures, schools and community centers. The Program will subsidize up to 100% of the cost of the audit. The Board of Public Utilities (BPUs) Office of Clean Energy has assigned TRC Energy Services to administer the Program. Steven Winter Associates, Inc. (SWA) is a 38-year-old architectural/engineering research and consulting firm, with specialized expertise in green technologies and procedures that improve the safety, performance, and cost effectiveness of buildings. SWA has a long-standing commitment to creating energy-efficient, cost-saving and resource-conserving buildings. As consultants on the built environment, SWA works closely with architects, developers, builders, and local, state, and federal agencies to develop and apply sustainable, ‗whole building‘ strategies in a wide variety of building types: commercial, residential, educational and institutional. SWA performed an energy audit and assessment for the Hardyston Township Middle School at 183 Wheatsworth Road, Hamburg, NJ 07419. The process of the audit included facility visits on October 27, 2010 and November 2, 2010, benchmarking and energy bills analysis, assessment of existing conditions, energy modeling, energy conservation measures and other recommendations for improvements. The scope of work includes providing a summary of current building conditions, current operating costs, potential savings, and investment costs to achieve these savings. The facility description includes energy usage, occupancy profiles and current building systems along with a detailed inventory of building energy systems, recommendations for improvement and recommendations for energy purchasing and procurement strategies. The goal of this Local Government Energy Audit is to provide sufficient information to the Hardyston Township Board of Education to make decisions regarding the implementation of the most appropriate and most cost-effective energy conservation measures for the Hardyston Township Middle School.

Energy benchmarking

SWA has entered energy information about the Hardyston Township Middle School in the U.S. Environmental Protection Agency‘s (EPA) ENERGY STAR® Portfolio Manager energy benchmarking system. This facility is categorized as a K-12 School space type. The Hardyston Township Middle School has a national energy performance rating of 19. The Site Energy Use Intensity is 109 kBtu/sqft/yr compared to the national average of a K-12 School building consuming 90 kBtu/sqft/yr. See ECM section for guidance on how to improve the building‘s rating. Due to the nature of its calculation based upon a survey of existing buildings of varying usage, the national average for K-12 School space types is very subjective, and is not an absolute bellwether for gauging performance. Additionally, should the Hardyston Township desire to reach this average there are other large scale and financially less advantageous improvements that can be made, such as envelope window, door and insulation upgrades that would help the building reach this goal.

Per the LGEA program requirements, SWA has assisted the Hardyston Township Board of Education to create an ENERGY STAR® Portfolio Manager account and share the Hardyston Township Middle School facilities information to allow future data to be added and tracked using the benchmarking tool. SWA has shared this Portfolio Manager account information with the Hardyston Township (user name of ―hardystontwpboe‖ with a password of ―hardystontwpboe‖) and TRC Energy Services (user name of ―TRC-LGEA‖). Tariff analysis

Tariff analysis can help determine if the Hardyston Township Middle School is paying the lowest rate possible for electric and gas service. Tariffs are typically assigned to buildings based on size and building type. Rate fluctuations are expected during periods of peak usage. Natural gas prices often increase during winter months since large volumes of natural gas is needed for heating equipment. Similarly, electricity prices often increase during the summer months when additional electricity is needed for cooling equipment. As part of the utility bill analysis, SWA evaluated the current utility rates and tariffs for the Hardyston Township Middle School. The Hardyston Township Middle School is currently paying a general service rate for natural gas including fixed costs such as meter reading charges. The electric use for the building is direct-metered and purchased at a general service rate with an additional charge for electrical demand factored into each monthly bill. The general service rate is a market-rate based on electric usage and electric demand. Demand prices are reflected in the utility bills and can be verified by observing the price fluctuations throughout the year.

The Hardyston Middle School currently has a contract with North American Power Partners (NAAP) for a Demand Response program up to 260 kW. Therefore, upon request by NAPP, the Middle School agreed to be able to reduce their electrical demand up to 260 kW. In return for the willingness to reduce electric demand the program provides approximately $1,400 per quarter to the Township even if they are not called. Building staff has been able to accommodate the load shed in the past by operating certain sections of the building in Unoccupied Mode or Holiday Mode through the Building Management System.

Energy Procurement strategies

Billing analysis was conducted using an average aggregated rate which is estimated based on the total cost divided by the total energy usage for each utility over a 12 month period. Average aggregated rates do not separate demand charges from usage, and instead provide a metric of inclusive cost per unit of energy. Average aggregated rates are used in order to equitably compare building utility rates to average utility rates throughout the state of New Jersey. The average estimated NJ commercial utility rates for electric are $0.150/kWh, while Hardyston Township Middle School pays a rate of $0.166/kWh. The Hardyston Township Middle School annual electric utility costs are $17,295 higher, when compared to the average estimated NJ commercial utility rates. Electric bill analysis shows fluctuations up to 15% over the most recent 12 month period.

The average estimated NJ commercial utility rates for gas are $1.550/therm, while Middle School pays a competitive rate of $1.283/therm. Natural gas bill analysis shows fluctuations up to 79% over the most recent 12 month period.

Utility rate fluctuations may have been caused by adjustments between estimated and actual meter readings; others may be due to unusual high and recent escalating energy costs. The unusual trend in the graph above is due to low natural gas usage during the summer months and a minimum service charge. For graphical purposes, the months of July and August are set to zero. SWA encourages the Hardyston Township Middle School to continue with the demand response program through NAPP. After energy saving measures have been implemented, building staff should test the system to ensure that load shedding up to 260 kW is still feasible. SWA also recommends that the Hardyston Township further explore opportunities of purchasing both natural gas and electricity from third-party suppliers in order to reduce rate fluctuation and ultimately reduce the annual cost of energy. Appendix C contains a complete list of third-party energy suppliers for the Hardyston Township Board of Education service area.

Building Occupancy Profiles

The Hardyston Township Middle School approximate hours of operation are: Monday through Friday 7:30am-4:00am when teachers arrive/leave, students arrive at 8:00am and depart at 2:45pm; sport activities afterhours to 9:00pm. The last gym class during the day is at 10:00am.

Page 14: Hardyston Township Board of Education - Amazon S3 · Smart Start: Most of energy savings equipment and design measures have moderate incentives under this program. Renewable Energy

Steven Winter Associates, Inc. - LGEA Report Hardyston Township – Middle School Page 14/78

Heating/cooling setback is 4:00pm - 6:00am and weekends. School cleaning activities continue on weekdays to 11:00pm. There are no summer activities except for the front offices, and Tuesday and Thursday 4:00pm - 8:00pm there is Men‘s basketball.

Building Envelope

Due to unfavorable weather conditions (min. 18 deg. F delta-T in/outside and no/low wind), no exterior envelope infrared (IR) images were taken during the field audit. General Note: All findings and recommendations on the exterior envelope (base, walls, roofs, doors and windows) are based on the energy auditors‘ experience and expertise, on construction document reviews (if available) and on detailed visual analysis, as far as accessibility and weather conditions allowed at the time of the field audit.

Exterior Walls

The exterior wall envelope is mostly constructed of brick veneer and some decorative CMU (Concrete Masonry Unit) accents, over concrete block with 1-1/2 inches of polyisocyanurate board insulation. Other areas are constructed with 3 inches of EIFS (Exterior Insulation Finishing System) over concrete block. The interior is mostly painted gypsum wallboard, brick and painted CMU. Note: Wall insulation levels could not be verified in the field and are based on available construction plans. Exterior wall surfaces were inspected during the field audit. They were found to be in overall good condition with no signs of uncontrolled moisture, air-leakage or other energy-compromising issues detected on all facades. Interior walls were found to have cracks. The following specific exterior wall problem spots and areas were identified:

Efflorescence on brick and masonry walls indicate moisture presence within the wall cavity.

Insect nesting poses a safety threat and un-caulked/un-sealed exterior wall penetrations reduces building tightness

Steven Winter Associates, Inc. - LGEA Report Hardyston Township – Middle School Page 15/78

Cracked interior walls due to settling foundation

Roof

The building‘s roof is a combination salt box, shed and gable type over a steel structure, with an asphalt shingle finish. It was renovated in 2009. One and a half inches of polyiso (polyisocyanurate, foil faced) foam board attic/ceiling insulation was recorded. Other parts of the building are also covered by a flat and parapet type over steel decking with a built-up asphalt finish and reflective coating. One and a half inches of polyiso (polyisocyanurate, foil faced) foam board attic/ceiling insulation, and one and a half inches of polyiso (polyisocyanurate, foil faced) foam board roof insulation, were recorded. There was an issue with the Media center experiencing water damage near windows. The suspected cause is water infiltration through the soffit vent. During the 2009 renovation the vent was repaired, but a perforated panel still allows for water leakage through the soffit which is at a 45° Angle. Note: Roof insulation levels could not be verified in the field, and are based on available construction plans. Roofs, related flashing, gutters and downspouts were inspected during the field audit. They were reported to be in overall good condition, with only a few signs of uncontrolled moisture, air-leakage or other energy-compromising issues mostly detected on flat roof areas. The following specific roof problem spots were identified:

Signs of standing water/pooling; 45° Soffit at Media Center

Base The building‘s base is composed of a slab-on-grade floor with a perimeter footing with concrete block foundation walls and slab edge/perimeter insulation.

Slab/perimeter insulation levels could not be verified in the field and are based on available construction plans. The building‘s base and its perimeter were inspected for signs of uncontrolled moisture or water presence and other energy-compromising issues. Overall the base was reported to be in good condition with no signs of uncontrolled moisture, air-leakage and/ or other energy-compromising issues neither visible on the interior nor exterior. Windows The building contains basically two different types of windows. The majority of windows in the open spaces including the lobby, gymnasium, cafeteria, stair case, and media center are fixed type, with an insulated aluminum frame, low-E coated, double glazed. The fixed windows vary in size throughout the building. Other windows are single hung with an insulated frame, low-E coated and double glazed. The single hung windows are predominantly located in the classrooms with interior roller shades. Windows, shading devices, sills, related flashing and caulking were inspected as far as accessibility allowed for signs of moisture, air-leakage and other energy compromising issues. Overall, the windows were found to be in good condition with no signs of uncontrolled moisture, air-leakage and/ or other energy-compromising issues. Exterior doors The building contains three different types of exterior doors:

Aluminum type exterior doors are located in the front of the building and are original/have never been replaced.

Aluminum and tempered glass type exterior doors are located on rear and either side of the building, and are original/have never been replaced.

Glass with aluminum frame type exterior doors are located in the front and east façade of the building, and are original/have never been replaced.

All exterior doors, thresholds, related flashing, caulking and weather-stripping were inspected for signs of moisture, air-leakage and other energy-compromising issues. Overall, the doors were found to be in acceptable condition with only a few signs of uncontrolled moisture, air-leakage and/ or other energy-compromising issues. The following specific door problem spots were identified:

Building air-tightness Overall the field auditors found the building to be reasonably air-tight, considering the building's use and occupancy, as described in more detail earlier in this chapter. The air tightness of buildings helps maximize all other implemented energy measures and investments, and minimizes potentially costly long-term maintenance, repair and replacement expenses.

Mechanical Systems

Heating Ventilation Air Conditioning The Hardyston Township Middle School has heating, cooling and ventilation for all occupied spaces. There is a system wide Building Management System (BMS) which monitors the operation and set points for all mechanical equipment. During the field visit there was no major comfort issues reported.

Equipment

The Hardyston Township Middle School is heated and cooled by several air handling units which deliver heated and cooled air to the building spaces. The air handling units are served by three condensing boilers and two air-cooled chillers. A comprehensive Equipment List can be found in Appendix A. Condensing boilers can reach efficiencies up to 95% due to their design. Typical boilers have a single heat exchanger to transfer hear between the hot flue gases and the heating water. Condensing boilers however have a second heat exchange, transferring more heat to the water. As a result the flue gas temperature can drop to 130°F and the water vapor within the flue gases condenses to a liquid and falls to the base of the flue pipe. The Middle School has three Aerco Benchmark 2.0 condensing boilers with 2,000 MBH capacity each, 92.0% rated thermal efficiency and 20:1 rated turn-down. The boilers appear in good operating condition. One of the boilers was operating during the field audit yet all of the outside air dampers in the mechanical room were closed, which is a Fire Code violation. The current sequence of operations indicates that the outside air dampers will open upon activation of any of the three boilers; however this was not the case. This issue should be investigated to ensure safe operation of combustion equipment.

Three Aerco Condensing Boilers with Stainless Steel Flue; Boiler Air Intake Fan

The condensing boilers produce hot water for air handling unit hot water coils, a domestic hot water heat exchanger, unit heaters, cabinet unit heaters and fin tube radiators. The Middle School is cooled during the summer season by two air-cooled chillers. One is a Carrier Twin-Screw Chiller with three compressors providing a total of 191.9 tons cooling capacity at a rated efficiency 9.56 EER with ten condenser fans. The second chiller is a Carrier Air-Cooled Reciprocating Chiller with two compressors providing 60 tons at a rated efficiency of 9.5 EER and four condenser fans although. One of the compressors is not operating and needs to be replaced. Multiple compressor design allows for compressor staging for high part load efficiency. The chillers are installed outside in an open-roof mechanical room and therefore the piping requires freeze protection. During the winter the chilled water piping is isolated at the building, drained, and a glycol solution is pumped into the piping to ensure that it does not freeze. The glycol is then drained and the piping is filled with water for the cooling season. Although this method of freeze protection is not as per design, there is no indication that draining the system requires more energy than using an electric heater as per design.

There is also one DX split unit for the kitchen walk-in refrigerator. The condenser is installed on the roof and appears in good condition.

Walk-In Refrigerator Condenser

There are eight Carrier air handling units, AHU-1 through AHU-8 serving the building. The air handlers have either one or two air distribution fans or heating and cooling coils to serve occupied spaces. There is also a Reznor gas-fired air pre-heater installed to compensate heat loss to the kitchen due the high volume of air loss for exhaust. Staff reports that there are no heating issues in the kitchen and therefore the gas supply to the heater is normally closed. The AHUs range in capacity, from 8,000 CFM to 15,000 CFM and they are installed in mechanical rooms and on the roof. The units were installed in 2003 and appear in good operating condition.

AHU-1 Supply Fan and Motor

AHU- 5 and AHU-7 are installed in the 2nd floor mechanical room and have separated return air fans, RAF-5 and RAF-7 respectively. In this arrangement the mechanical room acts as an air plenum as the return air fills the space and the supply fans draw in a measurable amount of return air. Each of the air handlers have a dedicated outside air intake damper to balance with the amount of return air. There is also a mechanical room outside air damper which provides additional ventilation air for the units. Using the mechanical room as a return air plenum requires that the space is tightly sealed to avoid thermal and pressure losses and is generally not recommended.

Separated RAF-5 and AHU-5 in 2nd Fl MER; AHU-8 in Mezzanine MER

The various spaces of the building are provided ventilation by outside air intake louvers on each of the air handling units as well as outside air dampers in each mechanical room. The outside air louvers are motorized to allow economizer operation when the outside air conditions are favorable. Each AHU has a purge damper to exhaust enough return air to balance with the volume of fresh air drawn into the unit. AHU-2 and AHU-3 in the gymnasium have wall-mounted motorized dampers which exhaust directly to the outside.

AHU-1 Return Air and Outside Air Damper with actuator linkage

There are also 12 exhaust fans located on the roof which serve the bathrooms, the kitchen and general exhaust for offices and classrooms. Not all fans were accessible during the field visit since several are installed above hard ceilings. The fans range from 0.25 HP for bathrooms to 3.0 HP for the kitchen. In general, the building exhaust fans have an estimated 65% useful operating life left and appear in good operating condition.

Rooftop Exhaust Fans

There are several supplementary hot water fin tube radiators, cabinet unit heaters and unit heaters for mechanical rooms and entrance/exits.

Perimeter Hot Water Fin Tubes; Hot Water Cabinet Unit Heater

Hot Water Unit Heater

Distribution Systems An air handling unit (AHU) has at least one motorized fan which draws in fresh air and brings it into a mixing box, where it is combined with return air from the building. A small portion of the return air is purged and vented outside prior to entering the mixing box. The mixed air inside the air handler is sent through a filter before passing through the chilled water cooling coil. The air then passes through the hot water heating coil and then the conditioned air is distributed to the building spaces. The heating coil is typically only active in the heating season and the cooling coil is only active in the cooling season. During moderate outside air conditions only the air supply fan will remain active to provide ventilation to the building as per code requirement. Some units have the Economizer Mode feature where a motorized outside air damper adjusts the amount of outside air intake when conditions are favorable to cool the building, or uses heat from exhaust air to heat the building, saving energy. CO2 monitors in the return air system of the building ensure that the ventilation code requirement is met for all operating modes.

Page 23: Hardyston Township Board of Education - Amazon S3 · Smart Start: Most of energy savings equipment and design measures have moderate incentives under this program. Renewable Energy

Steven Winter Associates, Inc. - LGEA Report Hardyston Township – Middle School Page 23/78

The hot water and chilled water is distributed to air handling unit coils and heating equipment by a series of pump sets. There are two primary chilled water pumps sized 7.5 HP and 15.0 HP which distribute water between the chiller and the mechanical room and two secondary pumps sized for 25.0 HP which distribute chilled water to air handing units. There are two hot water pumps sized for 25.0 HP. The pump motors are all standard efficiency, between 88.5% and 91.7% and have approximately 65% remaining useful life. The chilled water distribution pump motors are controlled by Variable Speed Drives (VSD) for increased part load efficiency.

Boiler Room Pump Sets

There are also ten freeze protection pumps installed on the hot water or chilled water piping serving the AHUs, which circulates hot water through the piping when the outside air temperature drops below 38°F. AHU-1, 2 and 3 are installed outside and therefore have freeze protection pumps on the hot water supply and chilled water supply piping. All other AHUs have the freeze protection pumps only on the hot water return piping. The pumps are 1/6 HP each and appear in good operating condition. The Hardyston Township Middle School has a Variable Air Volume (VAV) system, using VAV boxes throughout the ductwork system. The VAV boxes have a motorized modulating damper within the ductwork to adjust the amount of supply air to satisfy the temperature settings of the room(s) that it serves. The VAVs have direct digital control with Automated Logic Control software to perform the controls logic. There are hot water reheat coils upstream of each VAV box to provide supplemental heat when supply air is cooled below set point for dehumidification. The boilers, therefore, operate in the summer.

Steven Winter Associates, Inc. - LGEA Report Hardyston Township – Middle School Page 24/78

VAV Box installed upstream of supply diffuser

Controls All the heating and cooling equipment is controlled by programmable thermostats which are adjustable through a computerized Building Management System (BMS) by Automated Logic Corporation (ALC). The building occupants can adjust the setpoint 2°F plus or minus the standard setpoint by adjusting a manual lever at each thermostat. Also there is an LED indicator for Occupied Mode operation on each thermostat. During unoccupied hours the teachers and staff can override this mode and force the thermostat to operate in Occupied Mode. The level of controllability by occupants is completely modifiable by building staff through the BMS. All AHU fans have VFD control except for AHU-2 and AHU-3 which are constant volume units since they only serve the Gymnasium. In each room, as the VAV boxes close, the required air volume changes and the VFDs can increase or decrease the AHU fan motor speed to optimize efficiency. There is a cubed relationship between Brake Horsepower and speed. Therefore, when the VFD reduces the motor speed by 50%, the Brake horsepower reduces by 87.5%, generating significant energy savings during part load operation. As mentioned there is also VFD control for the secondary chilled water pumps so that as cooling coil valves close, and less water is needed, the VFD can reduce the pump motor speed. Installing VFDs for the hot water distribution pumps would provide additional energy savings.

VFDs for AHU-5, AHU-7 & AHU-1 fan motors; Typical ALC thermostat

The boilers and chillers operate based on outside air reset, building temperature set points and a specific occupancy schedule based on season. The hot water and chilled water control system including pump VFDs and motorized valves operates to satisfy the temperature set point. The air volume control system including AHU fan VFDs, VAV Boxes and motorized dampers operate to satisfy static pressure. There is a 3˚F deadband built into the thermostats which indicates that the heating and cooling equipment will not operate when the space is within that temperature range to avoid excessive hunting. The ALC control system at the Middle School provides graphic interface to monitor the building conditions and equipment operation.

First Floor Graphic on ACL

Each AHU can be monitored by several control points such as, damper % open position, return air temp, fan VFD % speed, outside air temp and CFM, hot water and chilled water valve % open position, freezestat status, static pressure, mixed air temperature and supply air temperature. Each control point is a visual display of a physical sensor reading which requires regular calibration.

ALC also allows for long term trending data to observe building behavior over time. This tool can be instrumental in observing times of peak operation and can be used to adjust setpoints and schedules for optimal operation.

AHU-2 24 hour Zone Temp Trending through ACL

It was observed that during the winter season, the hot water supply and return water temperature were nearly the same, no more than 1.0°F. During the field visit the BMS Hot Water supply temperature displayed on the BMS was 4.0°F lower than the temperature on a physical thermostat installed on the piping downstream of an active hot water supply pump. SWA monitored the hot water system through the BMS intermittently and the same trend occurred. During one particular scenario, during Occupied hours, the AHU-4 hot water coil valve indicated ―100% open‖ and heating 10,241 CFM of mixed air from 64.0°F to 81.5°F air, which requires 194,630 Btu/hr. The ―Hot Water System‖ graphic at the same time indicated that the main Hot Water Return temperature is 158.0°F and Hot Water Supply temperature

Page 27: Hardyston Township Board of Education - Amazon S3 · Smart Start: Most of energy savings equipment and design measures have moderate incentives under this program. Renewable Energy

is only 158.5°. Hot water pump P-4a was operating at 100% speed, pumping 425 GPM, and therefore the heat produced would only be 106,250 Btu/hr. The graphic therefore indicates that the boiler is producing almost half of the heat being used by AHU-4 alone and the boilers serve much more than AHU-4. The hot water system sensors are therefore not properly calibrated or may be located on a branch of the piping near a boiler that does not normally operate. The temperature sensors should be installed on the main supply and return branch piping to avoid inaccurate temperature variations based on boiler operation, and regularly calibrated.

Domestic Hot Water The domestic hot water (DHW) for the Hardyston Township Middle School is provided by a water to water heat exchanger with 1,000 gallons storage capacity. The exchanger uses boiler hot water to storage heated water for the building. The tank was originally sized to supply the Gymnasium locker room showers, but they are not used and therefore the heater is grossly oversized. The heater has 72% estimated useful operating life remaining and appears in good condition. The Middle School domestic cold water is provided by a well pump in the exterior mechanical room. The pump set is sized for 5.0 HP with 90 gallons storage and maintains 35.0 psig pressure

Lighting See attached lighting schedule in Appendix B for a complete inventory of lighting throughout the building including estimated power consumption and proposed lighting recommendations. As of July 1, 2010 magnetic ballasts most commonly used for the operation of T12 lamps will no longer be produced for commercial and industrial applications. Also, many T12 lamps will be phased out of production starting July 2012. Interior Lighting – The Hardyston Township Middle School currently contains mostly T8 fixtures, recessed compact fluorescent bi-pin fixtures and recessed compact fluorescent

Appliances and process

SWA has conducted a general survey of larger, installed equipment. Appliances and other miscellaneous equipment account for a significant portion of electrical usage within the building. Typically, appliances are referred to as ―plug-load‖ equipment, since they are not inherent to the building‘s systems, but rather plug into an electrical outlet. Equipment such as process motors, computers, computer servers, radio and dispatch equipment, refrigerators, vending machines and printers all create an electrical load on the building that is hard to separate out from the rest of the building‘s energy usage based on utility analysis.

Vending machines found in lobby and faculty room.

Elevators The Hardyston Township Middle School elevator serves the Ground, 1st and 2nd floors. It is an Arrow hydraulic type operated by a pump driven by a 40.0 HP motor. Other electrical systems There are several energy-impacting electrical systems installed at the Middle School. During an emergency the 60.0 kVa Cummins Emergency Generator activates to supply power to the emergency panel. There are also seven electrical transformers sized between 9.0 kVa and 112.5 kVa serving large mechanical equipment. During a fire emergency, in addition to the emergency generator, a fire pump activates. The fire pump is sized for 25.0 HP and 89.5% efficiency and is only intermittently tested, and generally not operating. The emergency electrical equipment is regularly tested and appears in good condition. There are two server rooms in the building with server equipment which generate a significant heat load. Staff reported concerns that one of these rooms does not have

adequate cooling or ventilation to dissipate the heat. Often server equipment can easily withstand temperatures as high as 92°F without damage. The Middle School should investigate the manufacturers recommended temperature setpoint for the equipment and adjust the room controls to match.

RENEWABLE AND DISTRIBUTED ENERGY MEASURES Renewable energy is defined as any power source generated from sources which are naturally replenished, such as sunlight, wind and geothermal. Technology for renewable energy is improving and the cost of installation is decreasing due to both demand and the availability of government-sponsored funding. Renewable energy reduces the need for using either electricity or fossil fuel, therefore lowering costs by reducing the amount of energy purchased from the utility company. Solar photovoltaic panels and wind turbines use natural resources to generate electricity. Geothermal systems offset the thermal loads in a building by using water stored in the ground as either a heat sink or heat source. Cogeneration or Combined Heat and Power (CHP) allows for heat recovery during electricity generation.

Existing systems Currently there are no renewable energy systems installed in the building. Evaluated Systems Solar Photovoltaic Photovoltaic panels convert light energy received from the sun into a usable form of electricity. Panels can be connected into arrays and mounted directly onto building roofs, as well as installed onto built canopies over areas such as parking lots, building roofs or other open areas. Electricity generated from photovoltaic panels is generally sold back to the utility company through a net meter. Net-metering allows the utility to record the amount of electricity generated in order to pay credits to the consumer that can offset usage and demand costs on the electric bill. In addition to generation credits, there are incentives available called Solar Renewable Energy Credits (SRECs) that are subsidized by the state government. Specifically, the New Jersey State government pays a market-rate SREC to facilities that generate electricity in an effort to meet state-wide renewable energy requirements. Based on utility analysis and a study of roof conditions, the Middle School is a good candidate for a 50 kW Solar Panel installation. See ECM# 6 for details.

Solar Thermal Collectors Solar thermal collectors are not cost-effective for this building and would not be recommended due to the insufficient and intermittent use of domestic hot water throughout the building to justify the expenditure.

Wind

The Middle School is not a good candidate for wind power generation due to insufficient wind conditions in this area of New Jersey. Geothermal The Middle School is not a good candidate for geothermal installation since it would require replacement of the entire existing HVAC system, of which major components still have between 65% and 80% remaining useful life.

Steven Winter Associates, Inc. - LGEA Report Hardyston Township – Middle School Page 33/78

Combined Heat and Power The Middle School is not a good candidate for CHP installation and would not be cost-effective due to the size and operations of the building. Typically, CHP is best suited for buildings with a high electrical baseload to accommodate the electricity generated, as well as a means for using waste heat generated. Typical applications include buildings with an absorption chiller, where waste heat would be used efficiently.

ECM#1: Upgrade (2) Incandescent Flood Light Fixtures to CFLs During the field audit, SWA completed a building lighting inventory (see Appendix B). The existing lighting also contains inefficient incandescent lamps. SWA recommends that each incandescent lamp is replaced with a more efficient, Compact Fluorescent Lamp (CFL). CFLs are capable of providing equivalent or better light output while using less power when compared to incandescent, halogen and Metal Halide fixtures. CFL bulbs produce the same lumen output with less wattage than incandescent bulbs and last up to five times longer. The labor for the recommended installations is evaluated using prevailing electrical contractor wages. The building owner may decide to perform this work with in-house resources from the Maintenance Department on a scheduled, longer timeline than otherwise performed by a contractor.

ECM#3: Replace 21 Standard Efficiency Motors with Premium Efficiency During the field audit, SWA completed the building equipment inventory and observed standard efficiency motors. Efficiency varies by motor size, with larger motors tending toward higher efficiency. The highest-efficiency motors available commercially today have efficiencies of 93-94%, and higher for the largest motors. Premium-efficiency motors cost 15-25% more than standard motors but they pay for themselves quickly in operating costs. SWA recommends replacing 21 motors ranging from 3 HP and 10 HP, which are used for air handling unit supply and return fans, chilled water pumps and the hot water distribution pumps, as listed in the table below. Even though most of these motors operate with Variable Speed Drives, there is still significant savings by increasing motor efficiencies by 0.6% to 3%. This is particularly true for air handling unit motors which operate during all seasons to provide minimum ventilation. All of the motors are original except for AHU-1 supply and return fan motors, and therefore, their efficiencies have likely depreciated over the past seven years of operation. SWA assumed that the existing motors operate at their rated efficiencies and the savings are based on the hours of operation of each unit as indicated on the Building Management System. The exact length of the payback period depends on several factors, including annual hours of use, energy rates, costs of installation and downtime, and the availability of utility rebates. The labor for the recommended installations is evaluated using prevailing electrical contractor wages. The building owner may decide to perform this work with in-house resources from the Maintenance Department on a scheduled, longer timeline than otherwise performed by a contractor.

Assumptions: SWA assumed that the air handling unit motors will operate for 10 hours each week day regardless of season at variable speed based on the temperature conditions. A diversity factor of 63.1% based on HDD and CDD was used to account for the effect of the VFDs. AHU-2 and AHU-3 motor savings did not have a diversity factor. For the pump motor savings it was assumed that 10 hours of operation each weekday from October through May for hot water pumps and June and September for chilled water pumps. Again, a separate diversity factor based on season applied to each pump calculation. As a conservative measure, it was also assumed that the motors would not operate during July and August.

ECM#4: Replace (24) Pulse Start and Quartz Halogen Fixtures with New T8 fixtures During the field audit, SWA completed a building interior as well as exterior lighting inventory (see Appendix B). The existing Hardyston Township Middle School lighting consists of 14 Pulse Start Metal Halide (PSMH) and 10 Quartz Halogen lamps. SWA recommends replacing the interior higher wattage PSMH and quartz halogen fixtures with T8 lamps and electronic ballasts which offer the advantages of standard PSMH lamps, but minimize the disadvantages. They produce higher light output both initially and over time, operate more efficiently, produce whiter light, and turn on and re-strike faster. Due to these characteristics, energy savings can be realized via one-to-one substitution of lower-wattage systems, or by taking advantage of higher light output and reducing the number of fixtures required in the space. The labor for the recommended installations is evaluated using prevailing electrical contractor wages. The building owner may decide to perform this work with in-house resources from the Maintenance Department on a scheduled, longer timeline than otherwise performed by a contractor.

ECM#5: Retro-Commissioning Retro-commissioning is a process that seeks to improve how building equipment and systems function together. Depending on the age of the building, retro-commissioning can often resolve problems that occurred during design or construction and/or address problems that have developed throughout the building‘s life. Owners often undertake retro-commissioning to optimize building systems, reduce operating costs, and address comfort complaints from building occupants. The Middle School is a new building with a sophisticated controls system yet the energy usage is high, resulting in a performance rating in the 28th percentile based on comparison of similar buildings. In particular, the natural gas consumption seems high, contributing 57% of the total energy usage. This may be due to the issues with the boiler hot water return controls and also the part load operation of the boilers during the summer for reheats and the domestic hot water heat exchanger. The domestic hot water tank is 1,000 gallons capacity which is grossly oversized for the building hot water usage which is limited to bathroom sinks, laboratory sinks and kitchen equipment. Also, based on periodic viewing of the Variable Air Volume system through the Building Management System, there appears to be calibration issues in many locations. As per good engineering practice, the HVAC system should be air balanced periodically to ensure accurate settings for each area of the building. The controls set points are only useful if the equipment is properly calibrated and the damper positions are set to accommodate the maximum air supply as per design. In addition, the arrangement of the air handling units in the Mechanical Room for AHU- 5 and AHU -7 is designed to use the Mechanical Room as a return air plenum. This type of design requires a very tight envelope to avoid pressure and thermal losses and may be a source of wasted energy. SWA recommends undertaking retro-commissioning to optimize system operation and to ensure that all equipment and sensors are properly calibrated. The retro-commissioning process should include a review of existing operational parameters for both newer and older installed equipment. During retro-commissioning, the individual loop temperatures and (setback) schedules should also be reviewed to identify opportunities for optimizing system performance, besides air balancing and damper proper operation.

ECM#6: Upgrade BMS System to Include Lighting Controls During the field audit, SWA completed a building HVAC controls analysis and observed that the controls system fully integrates the HVAC equipment, however there can be an added benefit by including the lighting controls in the Building Management System. Based utility analysis and field inspections, the current lighting electric consumption is 26% of the total electric consumption, and 11% of the total energy consumption. A significant amount of lighting is tied to emergency panels and remains on 24-hours a day, 5 days a week. Many of these fixtures are located in non-critical locations such as bathrooms, closets and mechanical rooms. It was estimated that the non-critical lighting on the emergency lighting system consumes 24,943 kWh annually, which is 8.8% of the total lighting usage. The only way to disable these lights currently is by a manual disconnect switch in the mechanical room; currently staff manually disconnect the emergency lighting over the weekend when the building is unoccupied. In addition, the lighting on each of the two main Corridors consists of 114 3'T8 fixtures and 44 of these fixtures are on the emergency panel and currently operate 24 hours a day. A lighting meter was used to determine the foot-candles in the corridor with different light arrangements. The results are as follows:

All 114 lights on: 28 fc (no more than 10 fc needed)

All emergency lights OFF: 15 to 22 fc

Only emergency lighting: 5.8 fc to 12 fc, with an average closer to 10 fc (only 1 fc required)

All Emergency Lighting on and only half of the non-emergency lights on: 16 to 22 fc The emergency lighting level in hallways as per code is 1 foot-candle and typically no more than 10 fc of light is needed for normal use. Therefore, SWA recommends that the BMS system be upgraded to include lighting controls for both non-emergency and emergency lighting and allow lighting controls based occupancy schedules. All savings and assumptions are conservatively based on measurable energy usage and full occupancy for the entire year however this level of controllability will likely result in even greater lighting energy savings particularly during the summer when many sections of the building are not used. The energy savings in the calculation below was based on the reducing the non-emergency lighting in the two main Corridors by 50% and that emergency lighting in non-critical spaces will operate for 12 hours a day instead of 24 hours. The integration of lighting into the BMS will also support installation of occupancy sensors which can be easily monitored for accuracy. Although not quantified in the savings calculation, the controls will also save staff maintenance costs by avoiding manual disconnect of emergency lighting.

Assumptions: SWA assumed a reduction by 50% of the electric consumption of the non-emergency lighting in the two main corridors and reduction of hours of operation by 50% for the non-critical lighting on the emergency panel. The specific fixtures are listed in the lighting spreadsheet in Appendix B. Rebates/financial incentives:

ECM#7: Install a 50 kW Solar Photovoltaic System Currently, the building does not use any renewable energy systems. Renewable energy systems such as photovoltaic (PV) panels can be mounted on the building roof facing south which can offset a portion of the purchased electricity for the building. Power stations generally have two separate electrical charges: usage and demand. Usage is the amount of electricity in kilowatt-hours that a building uses from month to month. Demand is the amount of electrical power that a building uses at any given instance in a month period. During the summer periods, electric demand at a power station is high, due to the amount of air conditioners, lights, and other equipment being used within the region. Demand charges increase to offset the utility‘s cost to provide enough electricity at that given time. Photovoltaic systems offset the amount of electricity used by a building and help to reduce the building‘s electric demand, resulting in a higher cost savings. Installing a PV system will offset electric demand and reduce annual electric consumption, while utilizing available state incentives. PV systems are modular and readily allow for future expansions. The size of the system was determined considering the available roof surface area, without compromising service space for roof equipment and safety, as well as the facilities‘ annual base load and mode of operation. It was determined that the roof can not support panels, therefore a PV system could be installed on open land behind the building or on a parking canopy with panels facing south. A commercial multi-crystalline 230 watt panel has 17.5 square feet of surface area (providing 13.1 watts per square foot). A 50 kW system needs approximately 218 panels which would take up 3,814 square feet. A PV system would reduce the building's electric load and allow more capacity for surrounding buildings as well as serve as an example of energy efficiency for the community. The building is not eligible for a residential 30% federal tax credit. The building owner may want to consider applying for a grant and / or engage a PV generator / leaser who would install the PV system and then sell the power at a reduced rate. Typically, a major utility provides the ability to buy SREC‘s at $600/MWh or best market offer. However, this option is not available from the local utility. Please see below for more information. Please note that this analysis did not consider the structural capability of the existing building to support the above recommended system. SWA recommends that the Hardyston Township Middle School contract with a structural engineer to determine if additional building structure is required to support the recommended system and what costs would be associated with incorporating the additional supports prior to system installation. Should additional costs be identified, the Hardyston Township Middle School should include these costs in the financial analysis of the project, as well as any roof covering and insulation upgrades.

Assumptions: SWA estimated the cost and savings of the system based on past PV projects. SWA projected physical dimensions based on a typical Polycrystalline Solar Panel (230 Watts, model #ND-U230C1). PV systems are sized based on Watts and physical dimensions for an array will differ with the efficiency of a given solar panel (W/sq ft). Rebates/financial incentives: NJ Clean Energy - Renewable Energy Incentive Program, Incentive based on $0.75 / watt Solar PV System up to 30 kW. Incentive amount for this application is $22,500 for the proposed option. http://www.njcleanenergy.com/renewable-energy/programs/renewable-energy-incentive-program NJ Clean Energy - Solar Renewable Energy Certificate Program. Each time a solar electric system generates 1,000kWh (1MWh) of electricity, a SREC is issued which can then be sold or traded separately from the power. The buildings must also become net-metered in order to earn SRECs as well as sell power back to the electric grid. A total annual SREC credit of $21,000 has been incorporated in the above costs however it requires proof of performance, application approval and negotiations with the utility. Options for funding ECM: This project may benefit from enrolling in NJ SmartStart program with Technical Assistance to offset a portion of the cost of implementation. http://www.njcleanenergy.com/commercial-industrial/programs/nj-smartstart-buildings/nj-smartstart-buildings Please see Appendix F for more information on Incentive Programs.

ECM#8: Upgrade (49) Metal Halide (MH) Fixtures to Pulse Start MH During the field audit, SWA completed a building interior as well as exterior lighting inventory (see Appendix B). The existing exterior lighting contains standard probe start Metal Halide (MH) lamps. SWA recommends replacing the higher wattage MH fixtures with pulse start MH lamps which offer the advantages of standard probe start MH lamps, but minimize the disadvantages. They produce higher light output both initially and over time, operate more efficiently, produce whiter light, and turn on and re-strike faster. Due to these characteristics, energy savings can be realized via one-to-one substitution of lower-wattage systems, or by taking advantage of higher light output and reducing the number of fixtures required in the space. The labor for the recommended installations is evaluated using prevailing electrical contractor wages. The building owner may decide to perform this work with in-house resources from the Maintenance Department on a scheduled, longer timeline than otherwise performed by a contractor.

ECM#9: Install (43) Occupancy Sensors

During the field audit, SWA completed a building lighting inventory (see Appendix B). SWA observed that the existing lighting has minimal to no control via occupancy sensors. SWA identified a number of areas that could benefit from the installation of occupancy sensors. SWA recommends installing occupancy sensors in areas that are occupied only part of the day and the payback on savings is justified. Typically, occupancy sensors have an adjustable time delay that shuts down the lights automatically if no motion is detected within a set time period. Advance micro-phonic lighting sensors include sound detection as a means to control lighting operation. The labor for the recommended installations is evaluated using prevailing electrical contractor wages. The building owner may decide to perform this work with in-house resources from the Maintenance Department on a scheduled, longer timeline than otherwise performed by a contractor.

PROPOSED FURTHER RECOMMENDATIONS

Capital Improvements Capital Improvements are recommendations for the building that may not be cost-effective at the current time, but that could yield a significant long-term payback. These recommendations should typically be considered as part of a long-term capital improvement plan. Capital improvements should be considered if additional funds are made available, or if the installed costs can be shared with other improvements, such as major building renovations. SWA recommends the following capital improvements for the Middle School:

Install premium motors when replacements are required - Select NEMA Premium motors when replacing motors that have reached the end of their useful operating lives.

Repair OA damper control in Boiler Room. As per code requirement, OA dampers must be open while combustion equipment is operating.

Replace damaged compressor on CH-2 with high efficiency, 30 ton unit as per manufacturer‘s recommendations. Expected cost is $28,000 to $32,000 to replace compressor.

Locate Boiler HWS and HWR sensors and calibrate (should be addressed in ECM#5, Retro-Commissioning). One or both sensors may be installed on a branch of the Hot Water header near a boiler which does not normally operate. The hot water temperature differential should be at least 10°F degrees for proper boiler performance. The efficiency benefit of condensing boilers is in having a low return water temperature as shown in the chart below and therefore it is essential that the boiler return water temperature be accurate:

Aerco Performance Curve

Source:http://www.rmcotton.com/ftpgetfile.php?id=73

The benefit of the BMS system is to accurately monitor the real time conditions of the system so that adjustments can be made to optimize the system. Without properly calibrated sensors, this value is lost.

Steven Winter Associates, Inc. - LGEA Report Hardyston Township – Middle School Page 50/78

Operations and Maintenance Operations and Maintenance measures consist of low/no cost measures that are within the capability of the current building staff to handle. These measures typically require little investment, and they yield a short payback period. These measures may 183 Wheatsworth School equipment settings or staff operations that, when 183 Wheatsworth Schooled will reduce energy consumption or costs.

Unclog and maintain all roof drains/scuppers.

Clean gutters and downspouts

Install/replace and maintain weather-stripping around all exterior doors and roof hatches.

Replace perforated soffit panels with solid panels on Media Center roof soffit in accordance with Cool-Vent manufacturer‘s recommendations. Repeat on any other sections experiencing water damage near windows.

Provide water-efficient fixtures and controls - Adding controlled on/off timers on all lavatory faucets is a cost-effective way to reduce domestic hot water demand and save water. Building staff can also easily install faucet aerators and/or low-flow fixtures to reduce water consumption. There are many retrofit options, which can be installed now or incorporated as equipment is replaced. Routine maintenance practices that identify and quickly 183 Wheatsworth School water leaks are a low-cost way to save water and energy. Retrofitting with more efficient water-consumption fixtures/appliances will reduce energy consumption for water heating, while also decreasing water/sewer bills.

SWA recommends that the building considers purchasing the most energy-efficient equipment, including ENERGY STAR® labeled appliances, when equipment is installed or replaced. More information can be found in the ―Products‖ section of the ENERGY STAR® website at: http://www.energystar.gov.

Use smart power electric strips - in conjunction with occupancy sensors to power down computer equipment when left unattended for extended periods of time.

Create an energy educational program - that teaches how to minimize energy use. The U.S. Department of Energy offers free information for hosting energy efficiency educational programs

and plans. For more information please visit: http://www1.eere.energy.gov/education/. Note: The recommended ECMs and the list above are cost-effective energy efficiency measures and building upgrades that will reduce operating expenses for the Hardyston Township Middle School. Based on the requirements of the LGEA program, Hardyston Township must commit to implementing some of these measures, and must submit paperwork to the Local Government Energy Audit program within one year of this report‘s approval to demonstrate that they have spent, net of other NJCEP incentives, at least 25% of the cost of the audit (per building). The minimum amount to be spent, net of other NJCEP incentives, is $3,834.

APPENDIX E: GLOSSARY AND METHOD OF CALCULATIONS Net ECM Cost: The net ECM cost is the cost experienced by the customer, which is typically the total cost (materials + labor) of installing the measure minus any available incentives. Both the total cost and the incentive amounts are expressed in the summary for each ECM. Annual Energy Cost Savings (AECS): This value is determined by the audit firm based on the calculated energy savings (kWh or Therm) of each ECM and the calculated energy costs of the building. Lifetime Energy Cost Savings (LECS): This measure estimates the energy cost savings over the lifetime of the ECM. It can be a simple estimation based on fixed energy costs. If desired, this value can factor in an annual increase in energy costs as long as the source is provided. Simple Payback: This is a simple measure that displays how long the ECM will take to break-even based on the annual energy and maintenance savings of the measure. ECM Lifetime: This is included with each ECM so that the owner can see how long the ECM will be in place and whether or not it will exceed the simple payback period. Additional guidance for calculating ECM lifetimes can be found below. This value can come from manufacturer‘s rated lifetime or warranty, the ASHRAE rated lifetime, or any other valid source. Operating Cost Savings (OCS): This calculation is an annual operating savings for the ECM. It is the difference in the operating, maintenance, and / or equipment replacement costs of the existing case versus the ECM. In the case where an ECM lifetime will be longer than the existing measure (such as LED lighting versus fluorescent) the operating savings will factor in the cost of replacing the units to match the lifetime of the ECM. In this case or in one where one-time repairs are made, the total replacement / repair sum is averaged over the lifetime of the ECM. Return on Investment (ROI): The ROI is expresses the percentage return of the investment based on the lifetime cost savings of the ECM. This value can be included as an annual or lifetime value, or both. Net Present Value (NPV): The NPV calculates the present value of an investment‘s future cash flows based on the time value of money, which is accounted for by a discount rate (assumes bond rate of 3.2%). Internal Rate of Return (IRR): The IRR expresses an annual rate that results in a break-even point for the investment. If the owner is currently experiencing a lower return on their capital than the IRR, the project is financially advantageous. This measure also allows the owner to compare ECMs against each other to determine the most appealing choices. Gas Rate and Electric Rate ($/therm and $/kWh): The gas rate and electric rate used in the financial analysis is the total annual energy cost divided by the total annual energy usage for the 12 month billing period studied. The graphs of the monthly gas and electric rates reflect the total monthly energy costs divided by the monthly usage, and display how the average rate fluctuates throughout the year. The average annual rate is the only rate used in energy savings calculations.

* The lifetime operating cost savings are all avoided operating, maintenance, and/or component replacement costs over the lifetime of the ECM. This can be the sum of any annual operating savings, recurring or bulk (i.e. one-time repairs) maintenance savings, or the savings that comes from avoiding equipment replacement needed for the existing measure to meet the lifetime of the ECM (e.g. lighting change outs).

Excel NPV and IRR Calculation In Excel, function =IRR (values) and =NPV(rate, values) are used to quickly calculate the IRR and NPV of a series of annual cash flows. The investment cost will typically be a negative cash flow at year 0 (total cost - incentive) with years 1 through the lifetime receiving a positive cash flow from the annual energy cost savings and annual maintenance savings. The calculations in the example below are for an ECM that saves $850 annually in energy and maintenance costs (over a 10 year lifetime) and takes $5,000 to purchase and install after incentives:

Solar PV ECM Calculation There are several components to the calculation: Costs: Material of PV system including panels, mounting and net-metering +

Labor Energy Savings: Reduction of kWh electric cost for life of panel, 25 years Incentive 1: NJ Renewable Energy Incentive Program (REIP), for systems of size

50kW or less, $1/Watt incentive subtracted from installation cost Incentive 2: Solar Renewable Energy Credits (SRECs) – Market-rate incentive.

Calculations assume $600/Megawatt hour consumed per year for a maximum of 15 years; added to annual energy cost savings for a period of 15 years. (Megawatt hour used is rounded to nearest 1,000 kWh)

Assumptions: A Solar Pathfinder device is used to analyze site shading for the building and determine maximum amount of full load operation based on available sunlight. When the Solar Pathfinder device is not implemented, amount of full load operation based on available sunlight is assumed to be 1,180 hours in New Jersey.

Total lifetime PV energy cost savings = kWh produced by panel * [$/kWh cost * 25 years + $600/Megawatt hour /1000 * 15 years]

ECM and Equipment Lifetimes Determining a lifetime for equipment and ECM‘s can sometimes be difficult. The following table contains a list of lifetimes that the NJCEP uses in its commercial and industrial programs. Other valid sources are also used to determine lifetimes, such as the DOE, ASHRAE, or the manufacturer‘s warranty. Lighting is typically the most difficult lifetime to calculate because the fixture, ballast, and bulb can all have different lifetimes. Essentially the ECM analysis will have different operating cost savings (avoided equipment replacement) depending on which lifetime is used. When the bulb lifetime is used (rated burn hours / annual burn hours), the operating cost savings is just reflecting the theoretical cost of replacing the existing case bulb and ballast over the life of the recommended bulb. Dividing by the bulb lifetime will give an annual operating cost savings. When a fixture lifetime is used (e.g. 15 years) the operating cost savings reflects the avoided bulb and ballast replacement cost of the existing case over 15 years minus the projected bulb and ballast replacement cost of the proposed case over 15 years. This will give the difference of the equipment replacement costs between the proposed and existing cases and when divided by 15 years will give the annual operating cost savings.
