I. EXECUTIVE SUMMARY

This report presents the findings of the energy audit conducted for:

Atlantic County Utilities Authority Operations B Building 1801 Absecon Blvd. ACUA Contact Person: Matthew von der Hayden

Facility Contact Person: Robert Carlson This audit is performed in connection with the New Jersey Clean Energy - Local Government Energy Audit Program. The energy audit is conducted to promote the mission of the office of Clean Energy, which is to use innovation and technology to solve energy and environmental problems in a way that improves the State’s economy. This can be achieved through the wiser and more efficient use of energy. The annual energy costs estimated for the B Building are as follows: This wastewater facility is unique in that it generates its own power via the first commercial wind project in New Jersey and the nation’s first coastal and urban wind farm. The rate is set by the Power Purchase Agreement at 8¢ per kWh. In addition, the site contains a 500-kilowatt photovoltaic solar array consisting of ground-mounted, roof-mounted and parking area canopy systems. Note: Electricity is delivered to the Operations B Building from the solar arrays or the local utility. When purchased from the local utility, the average blended rate is approximately 12¢ per kWh. When the electricity is supplied by the wind farm or solar arrays, the internally calculated rate is 8¢ per kWh. The actual usage split cannot be determined since the building is not sub-metered for usage from the local utility versus the wind or solar generated power. By reducing the usage of electricity at the Operations B Building, the facility will be using less power from the utility company and more of the wind generated power. Conservatively, CEG has used the 8¢ per kWh blended rate for all of the energy calculations in this report. The potential annual energy cost savings for each energy conservation measure (ECM) and renewable energy measure (REM) are shown below in Table 1. Be aware that the ECM’s and REM’s are not additive because of the interrelation of some of the measures. This audit is consistent with an ASHRAE level 2 audit. The cost and savings for each measure is ± 20%. The

Concord Engineering Group (CEG) recommends proceeding with the implementation of all ECM’s that provide a calculated simple payback at or under ten (10) years. The following Energy Conservation Measures are recommended for the facility:

• ECM #1: Lighting Upgrade

• ECM #2: Lighting Controls

• ECM #3: Steam Boiler Replacement

• ECM #4: Computer Monitor Replacement

• ECM #5: Water Conservation Opportunities

The ECM for the steam boiler replacement has a simple payback of over 10 years but due to the age of the boiler and that it is seriously oversized for the control room/office/lab heating load it is strongly recommended that it be replaced. In addition, a small increase in fuel oil pricing would change the simple payback to less than 10 years (for example, from $1.80 to $2.20 per gallon).

In addition to the ECMs, there are maintenance and operational measures that can provide significant energy savings and provide immediate benefit. The ECMs listed above represent investments that can be made to the facility which are justified by the savings seen overtime. However, the maintenance items and small operational improvements below are typically achievable with on site staff or maintenance contractors and in turn have the potential to provide substantial operational savings compared to the costs associated. The following are recommendations which should be considered a priority in achieving an energy efficient building: 1. Chemically clean the condenser and evaporator coils periodically to optimize efficiency.

Poorly maintained heat transfer surfaces can reduce efficiency 5-10%. 2. Maintain all weather stripping on entrance doors. 3. Clean all light fixtures to maximize light output. 4. Provide more frequent air filter changes to decrease overall system power usage and maintain

better IAQ.



II. INTRODUCTION

This comprehensive energy audit covers the 19,150 SF Operations B Building which consists of the Control Room, Water/Wastewater Environmental Testing Laboratory, Administration Offices, Conference Room, Shops, Receiving, Storage and Restroom/Lockers. No. 2 fuel oil and natural gas utility information was collected and analyzed for one full year’s energy use for the B Building. No. 2 fuel oil is used for the steam boiler to produce heating hot water through a steam converter and the natural gas is used for the infrared heating units in the shops, receiving, storage, etc. Electrical usage for the entire facility (single electric meter for the entire facility) was obtained in order to calculate a blended kWh rate for the energy savings calculations. The utility information allows for analysis of the building’s operational characteristics; calculate energy benchmarks for comparison to industry averages, estimated savings potential, and baseline usage/cost to monitor the effectiveness of implemented measures. The Energy Use Index (EUI) is established for the building. Energy Use Index (EUI) is expressed in British Thermal Units/square foot/year (BTU/ft2/yr), which is used to compare energy consumption to similar building types or to track consumption from year to year in the same building. The EUI is calculated by converting the annual consumption of all energy sources to BTU’s and dividing by the area (gross square footage) of the building. Blueprints (where available) are utilized to verify the gross area of the facility. The EUI is a good indicator of the relative potential for energy savings. A low EUI indicates less potential for energy savings, while a high EUI indicates poor building performance therefore a high potential for energy savings. Existing building architectural and engineering drawings (where available) are utilized for additional background information. The building envelope, lighting systems, HVAC equipment, and controls information gathered from building drawings allow for a more accurate and detailed review of the building. The information is compared to the energy usage profiles developed from utility data. Through the review of the architectural and engineering drawings a building profile can be defined that documents building age, type, usage, major energy consuming equipment or systems, etc. The preliminary audit information is gathered in preparation for the site survey. The site survey provides critical information in deciphering where energy is spent and opportunities exist within a facility. The entire site is surveyed to inventory the following to gain an understanding of how each facility operates:

• Building envelope (roof, windows, etc.) • Heating, ventilation, and air conditioning equipment (HVAC) • Lighting systems and controls



The building site visit is performed to survey all major building components and systems. The site visit includes detailed inspection of energy consuming components. Summary of building occupancy schedules, operating and maintenance practices, and energy management programs provided by the building manager are collected along with the system and components to determine a more accurate impact on energy consumption.



III. METHOD OF ANALYSIS

Post site visit work includes evaluation of the information gathered, researching possible conservation opportunities, organizing the audit into a comprehensive report, and making recommendations on HVAC, lighting and building envelope improvements. Data collected is processed using energy engineering calculations to anticipate energy usage for each of the proposed energy conservation measures (ECMs). The actual building’s energy usage is entered directly from the utility bills provided by the owner. The anticipated energy usage is compared to the historical data to determine energy savings for the proposed ECMs. It is pertinent to note, that the savings noted in this report are not additive. The savings for each recommendation is calculated as standalone energy conservation measures. Implementation of more than one ECM may in some cases affect the savings of each ECM. The savings may in some cases be relatively higher if an individual ECM is implemented in lieu of multiple recommended ECMs. For example implementing reduced operating schedules for inefficient lighting will result in a greater relative savings. Implementing reduced operating schedules for newly installed efficient lighting will result in a lower relative savings, because there is less energy to be saved. If multiple ECM’s are recommended to be implemented, the combined savings is calculated and identified appropriately. ECMs are determined by identifying the building’s unique properties and deciphering the most beneficial energy saving measures available that meet the specific needs of the facility. The building construction type, function, operational schedule, existing conditions, and foreseen future plans are critical in the evaluation and final recommendations. Energy savings are calculated base on industry standard methods and engineering estimations. Energy consumption is calculated based on manufacturer’s cataloged information when new equipment is proposed. Cost savings are calculated based on the actual historical energy costs for the facility. Installation costs include labor and equipment costs to estimate the full up-front investment required to implement a change. Costs are derived from Means Cost Data, industry publications, and local contractors and equipment suppliers. The NJ Smart Start Building® program incentives savings (where applicable) are included for the appropriate ECM’s and subtracted from the installed cost. Maintenance savings are calculated where applicable and added to the energy savings for each ECM. The life-time for each ECM is estimated based on the typical life of the equipment being replaced or altered. The costs and savings are applied and a simple payback, simple lifetime savings, and simple return on investment are calculated. See below for calculation methods:

IV. HISTORIC ENERGY CONSUMPTION/COST A. Energy Usage / Tariffs The energy usage for the facility has been tabulated and plotted in graph form as depicted within this section. Each energy source has been identified and monthly consumption and cost noted per the information provided by the Owner. This wastewater facility is unique in that it generates its own power via the first commercial wind project in New Jersey and the nation’s first coastal and urban wind farm. In addition, the site contains a 500-kilowatt photovoltaic solar array consisting of ground-mounted, roof-mounted and parking area canopy systems. The Operations B Building was sub-metered for an 8-month period when Rowan University was performing an energy audit of this building. This electric usage profile represents the estimated electrical usage for the Operations B Building. Note: Electricity is delivered to the Operations B Building from the solar arrays or the local utility. When purchased from the local utility, the average blended rate is approximately 12¢ per kWh. When the electricity is supplied by the wind farm or solar arrays, the internally calculated rate is 8¢ per kWh. The actual usage split cannot be determined since the building is not sub-metered for usage from the local utility versus the wind or solar generated power. By reducing the usage of electricity at the Operations B Building, the facility will be using less power from the utility company and more of the wind generated power. Conservatively, CEG has used the 8¢ per kWh blended rate for all of the energy calculations in this report. The gas usage profile shows the actual natural gas energy usage for the B Building. South Jersey Gas provides natural gas to the facility. The gas utility measures consumption in cubic feet x 100 (CCF), and converts the quantity into Therms of energy. One Therm is equivalent to 100,000 BTUs of energy. The oil usage profile shows the actual oil consumption for the facility. Oil is provided by Major Petroleum Industries to the facility. The oil provider measures consumption in gallons. One gallon of #2 fuel oil is equivalent to 140,000 BTUs of energy. The overall cost for utilities is calculated by dividing the total cost by the total usage. Based on the utility history provided, the average estimated cost for utilities at the B Building is as follows: Description Average

Electricity 8¢ per kWh Natural Gas $1.20 / Therm #2 Fuel Oil $1.80 /Gallon

B. Energy Use Index (EUI) Energy Use Index (EUI) is a measure of a building’s annual energy utilization per square foot of building. This calculation is completed by converting all utility usage consumed by a building for one year, to British Thermal Units (BTU) and dividing this number by the building square footage. EUI is a good measure of a building’s energy use and is utilized regularly for comparison of energy performance for similar building types. The Oak Ridge National Laboratory (ORNL) Buildings Technology Center under a contract with the U.S. Department of Energy maintains a Benchmarking Building Energy Performance Program. The ORNL website determines how a building’s energy use compares with similar facilities throughout the U.S. and in a specific region or state. Source use differs from site usage when comparing a building’s energy consumption with the national average. Site energy use is the energy consumed by the building at the building site only. Source energy use includes the site energy use as well as all of the losses to create and distribute the energy to the building. Source energy represents the total amount of raw fuel that is required to operate the building. It incorporates all transmission, delivery, and production losses, which allows for a complete assessment of energy efficiency in a building. The type of utility purchased has a substantial impact on the source energy use of a building. The EPA has determined that source energy is the most comparable unit for evaluation purposes and overall global impact. Both the site and source EUI ratings for the building are provided to understand and compare the differences in energy use. The site and source EUI for this facility is calculated as follows:

C. EPA Energy Benchmarking System The United States Environmental Protection Agency (EPA) in an effort to promote energy management has created a system for benchmarking energy use amongst various end users. The benchmarking tool utilized for this analysis is entitled Portfolio Manager. The Portfolio Manager tool allows tracking and assessment of energy consumption via the template forms located on the ENERGY STAR website (www.energystar.gov). The importance of benchmarking for local government municipalities is becoming more important as utility costs continue to increase and emphasis is being placed on carbon reduction, greenhouse gas emissions and other environmental impacts. Based on information gathered from the ENERGY STAR website, Government agencies spend more than $10 billion a year on energy to provide public services and meet constituent needs. Furthermore, energy use in commercial buildings and industrial facilities is responsible for more than 50 percent of U.S. carbon dioxide emissions. It is vital that local government municipalities assess facility energy usage, benchmark energy usage utilizing Portfolio Manager, set priorities and goals to lessen energy usage and move forward with priorities and goals. In accordance with the Local Government Energy Audit Program, CEG has created an ENERGY STAR account for the municipality to access and monitoring the facility’s yearly energy usage as it compares to facilities of similar type. The login page for the account can be accessed at the following web address; the username and password are also listed below:

V. FACILITY DESCRIPTION

The 19,151SF Operations B Building is a two-story with basement facility comprised of administration offices, control room, conference room, IT office, electronics shop, environmental labs, 4-bay garage, maintenance/repair shop, storage and a shipping/receiving area. The basement and second floor are no longer occupied and are kept at approximately 50°F during the winter months.

HVAC Systems

The facility is heated by a Cleaver Brooks oil-fired, sectional steam boiler with a rated capacity of 4,000 MBH input and 3,200 MBH output. A large portion of the steam feeds a steam-to-hot water convertor and the hot water is circulated to duct-mounted hot water coils, unit heaters, cabinet heaters and baseboard heaters via two (2) 1.5 HP pumps delivering 90 GPM at 30 feet TDH. The balance of the steam feeds several steam unit heaters. The basement and second floor of the original building are no longer used. The repair shops, storage and receiving areas have been converted to infra-red gas-fired heating. The domestic hot water that was produced by another steam-to-hot water convertor has been replaced by two (2) electric domestic hot water heaters. Therefore the estimated thermal efficiency for this boiler that is partially loaded, even in the coldest weeks of the winter, is approximately 50%.

The office, control room, and lab spaces are cooled by seven (7) rooftop units (cooling only) that range in size from 4 to 10 tons [two (2) of the units are heat pumps]. A 1.5 ton split unit serves the data room.

Exhaust System

Air is exhausted from the toilet rooms, locker rooms, and hallways through roof exhausters.

HVAC System Controls

The HVAC systems within the facility are controlled via a Honeywell which controls the hot water convertor, unit heaters, duct-mounted coils, and several exhaust fans. All of the rooftop units are controlled by thermostats located in various offices, the control room, conference room and labs.

Domestic Hot Water

Domestic hot water for the office restrooms and locker rooms is provided by a 120-gallon A. O. Smith electric hot water heater with two (2) electric elements rated at 3,375 watts each. The domestic hot water is circulated throughout the building by a hot water re-circ pump. The circulation pump is controlled by an aqua stat. The domestic hot water piping insulation appeared to be in good condition. The shops/receiving area restroom is serviced by an A. O. Smith domestic hot water heater with a 40-gallon capacity and two (2) electric elements rated at 3,375 watts each.



Lighting Typical lighting throughout the office/lab portion of the building is fluorescent tube lay-in fixtures with T-8 lamps and electronic ballasts. Some of the offices, corridors, storage spaces, utility closets and bathrooms in the buildings still have a variety of older fixtures with T12 lamps with magnetic ballasts. In addition, some of the existing exit signs have 7-Watt Compact Fluorescent Lamps (CFLs) or incandescent bulbs.



VI. MAJOR EQUIPMENT LIST

The equipment list contains major energy consuming equipment that through implementation of energy conservation measures could yield substantial energy savings. The list shows the major equipment in the facility and all pertinent information utilized in energy savings calculations. An approximate age was assigned to the equipment in some cases if a manufactures date was not shown on the equipment’s nameplate. The ASHRAE service life for the equipment along with the remaining useful life is also shown in the Appendix.

Refer to the Major Equipment List Appendix for this facility.



VII. ENERGY CONSERVATION MEASURES

ECM #1: Lighting Upgrade Description: The majority of the lighting throughout the Atlantic County Utilities Authority is provided with modern fixtures with T8 lamps and electronic ballasts. However, some of the offices, corridors, storage spaces, utility closets and bathrooms in the buildings still have a variety of older fixtures with T12 lamps with magnetic ballasts. It is recommended to replace all of the T12 fixtures in these areas with higher efficiency fluorescent T8 fixtures with electronic ballasts. This ECM includes retrofit of all T12 fixtures with Super T8 fixtures with electronic ballasts in the building. The new, energy efficient Super T8 fixtures will provide adequate lighting and will save on electrical costs due to better performance of the lamp and ballasts. Therefore, ACUA should not wait until the fixtures have reached their life expectancy since these electrical savings would be lost. This ECM also includes maintenance savings through the reduced number of lamps replaced per year. The expected lamp life of a Super T8 lamp is approximately 30,000 burn-hours, in comparison to the existing T12 lamps which is approximately 20,000 burn-hours. The facility will need approximately 33% less lamps replaced per year for each one for one fixture replaced. The last part of this ECM involves replacing some of the existing exit signs that have 7-Watt Compact Fluorescent Lamps (CFLs) or incandescent bulbs with the newer LED technology units. 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. From the Smart Start Incentive Appendix, the following incentives are warranted: For the LED Exit Sign: $20/LED Exit sign (≤75kW facility connected load) and $10/LED Exit sign (≥75kW facility connected load). Smart Start ® Incentive = (# of LED Exit fixtures x $10 per fixture) Smart Start ® Incentive = 5 fixtures x $10 per fixture = $50. For replacement of T12 to Super T8 with electronic ballast is $10 per fixture. Smart Start ® Incentive = (# of T8w/EB fixtures x $10 per fixture) Smart Start ® Incentive = 266 fixtures x $10 per fixture = $2,660.

ECM #1 - ENERGY SAVINGS SUMMARY



ECM #2: Lighting Occupancy Sensors / Daylight Sensors Description: In some areas the lighting is 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. Photocell control senses light levels and turn off or reduce lights when there is adequate daylight. Photocells are mostly used outside, but are becoming more popular in energy-efficient interior lighting designs as well. 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 10% of the total light energy controlled by occupancy sensors and 25% for daylight 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 wall-mounted and ceiling type sensors for individual offices, conference rooms, locker rooms, small repair shops, restrooms, etc. 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.

ECM #3: Heating System Upgrade Description:

The heating for the offices, control room, conference room, locker rooms, etc. is provided via an oil-fired 4,000 MBH, water-tube, Model 4, Series 100, low pressure steam boiler made by Cleaver Brooks. The boiler is approximately 24 years old and is near the end of its expected useful service life, which is thirty (30) years per ASHRAE. The boiler provides steam to a hot water converter. Generated heating hot water is circulated through the duct heaters, baseboard heaters and cabinet heaters in the building via a set of older hot water pumps.

Steam heating is an inherently inefficient process due to higher operating temperature of the system. An alternative to reduce the heating energy consumption of the building is to convert the entire heating system into hot water. In addition, the boiler is oversized for the current heating load since most of the heating and all of the domestic hot water load was taken off the boiler. Because of this, the boiler runs at part load conditions year round. Current average combustion efficiency of the boiler is estimated to be 55% due to part load conditions, limited turndown ratio or cycling losses, age of the equipment, rusting and sediment build-up on the heat transfer surfaces, deteriorating or missing insulation, outdated design and controls.

CEG recommends replacing the original 4,000 MBH oil-fired steam boiler with a smaller, gas-fired, high-efficiency, condensing, modular, hot water boiler to carry the load during the entire heating season. The efficiency of a condensing, hot water boiler can reach as high as 90% when the return water temperature is lowered. It is also recommended to install two (2) new hot water pumps to replace the existing hot water pumps, which are oversized for the current heating load.

Calculations are based on one (1) Aerco Benchmark 1.5 high efficiency, gas-fired, modular, condensing hot water boiler rated at 1,500 MBH input and a maximum output of between 1290 MBH and 1409 MBH output depending on return water temperature. The calculation results can be used for comparative purposes between existing and new system and can be used as a basis for overall heating energy use or operating cost. The Owner should retain a professional engineer to verify heating loads as well as the flow requirements prior to moving forward with this ECM. Energy Savings Calculations: Fuel consumption of the steam boiler plant is gathered in order to calculate the estimated annual steam production of the boiler plant. Then, the steam production info is used in a reverse calculation to obtain proposed annual fuel consumption based on improved efficiency.

ECM #4: Computer Monitor Replacement Description: The computers throughout the Atlantic County Utility Authority utilize CRT computer monitors. These computer monitors are used at almost every computer work station including the offices, computer labs, lounges, conference rooms, etc. These computer monitors are outdated and have several disadvantages such as; significantly increased higher energy consumption, uses large amount of desk space, poor picture quality, distortions and flickering image, secular glare problems, and high weight, and electromagnetic emissions. Many of the drawbacks are difficult to quantify except for the energy use. CRT monitors use considerably more energy than an alternative flat panel LCD monitor. Replacement of the existing CRT monitors with LCD monitors saves considerable energy as well as provides other ergonomic benefits as well. Based on the site survey it was noted that a large number of the computers were left on and allowed to run 24 / 7. The majority of the monitors were left in screen saver mode, which is deceiving since this mode only saves the computer screen from image burn in, however it does not save on energy consumption. The average operating hours for all computers and monitors is estimated based on the site survey observations. Energy consumption of computer monitors are based on manufacture’s specifications. This ECM includes replacement of all existing CRT monitors with LCD flat panel monitors throughout the administration offices / control room. Installation costs were neglected for this ECM with the intention that this ECM would be replaced by the ACUA employees.

ECM #5: Water Conservation Opportunities Description: Water conservation is defined as any action that reduces the amount of water withdrawn from water supply sources, reduces consumptive use, reduces the loss or waste of water, improves the efficiency of water use, increases recycling and reuse of water, or prevents the pollution of water. Conversely, water waste is the excessive use of potable water that is unproductive or does not reasonably sustain economic benefits or life forms, particularly where there is a shortage of potable water. Faucets for restrooms, kitchen, and workroom sinks vary in flow rates. Restroom sinks need no more than 1.5 gallons per minute and kitchen sinks need about 2.5 gallons per minute while workroom sinks may include automated controls and pre-mixed temperatures. Toilets and urinals account for almost half of a typical building’s water consumption. According to the Plumbing Foundation, replacing all existing toilets with 1.6 gallons per flush, ultra-low flow models and urinals with 1.0 gallons per flush models would save almost 5,000 gallons of water per person each year. A conventional showerhead is rated to use 3 to 5 gallons per minute at normal water pressure, about 60 psi. A 5-minute shower with a conventional showerhead typically consumes 15 to 25 gallons of water. High quality replacement showerheads that deliver 1 to 2.5 gallons per minute can save many gallons per shower. Products vary in price from $10 to $50. This ECM would install low flow high performance sink aerators and high performance shower heads with ultra low flow. Water Savings Calculations: The water savings for the faucet aerators and showerheads were calculated by using the U. S. Department of Energy Federal Energy Management Program (FEMP) energy cost calculators for faucets, showerheads and urinals. Additional information on the referenced calculators can be found at www1.eere.energy.gov/femp/technologies. Water and sewer rates obtained from Atlantic County are as follows: Water: $3.10/1,000 gallons + Sewer: $2.80/1,000 gallons = Total: $5.90/1,000 gallons Summary of the water savings for this facility are as follows: Plumbing Fixture # of Units Water/Sewer Savings Material $ Payback(Yrs.) Faucet Aerators 4 $45 $80 1.7 Showerheads 4 $43 $160 3.7



The basis of calculation for the low flow high performance sink aerator and high performance shower heads with ultra low flow is the UtilitySavers™ high performance Spray Stream. It is also assumed that the facility operators will install the new faucet aerators and showerheads. Cost Savings Summary:

Further Considerations Waste Heat Geothermal Technology Description: The Operations B Building is presently heated by a steam boiler that feeds a steam-to-hot water converter and cooled by rooftop units. This ECM would replace this heating/cooling system with a technology that incorporates heat pumps. Heat pumps move heat from one location to another, drawing heat from air or groundwater sources and transferring that heat into buildings. Wastewater follows a highly predictable temperature curve relative to outside air, and is warm in the winter and cool in the summer. NovaThermal Energy combines a geothermal heat pump with a patented anti-block filtration device to transfer heat energy directly from wastewater for commercial HVAC applications. In the heating cycle, warm wastewater is transported to the NovaThermal heat pump which absorbs this heat. The heat pump then transfers heat to the building’s clean water circulation loop, heating the building. The wastewater is then returned to the treatment plant, whereupon the 8-15°F temperature differential is dissipated. This ECM would install a NovaThermal Energy anti-block filtration unit and heat pump skid in the existing boiler room, pipe into the existing hot water circulation system, and provide the controls for the system. The cost does not include piping to/from the wastewater feed line, chilled water piping to the rooftop air handling units nor the installation of chilled water coils into the rooftop units and associated controls. These costs will need to be estimated once the preliminary engineering is completed. Energy Savings Calculations: See the Novathermal Energy Appendix for a detailed energy savings and capital cost study performed by NovaThermal Energy. This system uses intellectual property developed by NovaThermal Energy and this study/analysis should be considered proprietary information.

ENERGY SAVINGS SUMMARY



VIII. RENEWABLE/DISTRIBUTED ENERGY MEASURES This wastewater facility is unique in that it generates its own power via the first commercial wind project in New Jersey and the nation’s first coastal and urban wind farm. In addition, the site contains a 500-kilowatt photovoltaic solar array consisting of ground-mounted, roof-mounted and parking area canopy systems. Therefore renewable energy measures were not analyzed.



IX. ENERGY PURCHASING AND PROCUREMENT STRATEGY This wastewater facility is unique in that it generates its own power via the first commercial wind project in New Jersey and the nation’s first coastal and urban wind farm which contains five 1.5 MW wind turbines. This wind farm was installed under a Power Purchase Agreement. In addition, the site contains a 500-kilowatt photovoltaic solar array consisting of ground-mounted, roof-mounted and parking area canopy systems. Note: Electricity is delivered to the Operations B Building from the solar arrays or the local utility. When purchased from the local utility, the average blended rate is approximately 12¢ per kWh. When the electricity is supplied by the wind farm or solar arrays, the internally calculated rate is 8¢ per kWh. The actual usage split cannot be determined since the building is not sub-metered for usage from the local utility versus the wind or solar generated power. By reducing the usage of electricity at the Operations B Building, the facility will be using less power from the utility company and more of the solar and wind generated power. Conservatively, CEG has used the 8¢ per kWh blended rate for all of the energy calculations in this report. The ACUA is representative of a trend-setter within the state of New Jersey. The ACUA’s executive management and engineering staff are ahead of the majority of end users when it comes to both procuring energy and creating their own energy via renewable energy systems. Therefore, recommendations that would typically be made for an entity are not valid due to the ACUA’s forward thinking.



X. INSTALLATION FUNDING OPTIONS CEG has reviewed various funding options for the facility owner to utilize in subsidizing the costs for installing the energy conservation measures noted within this report. Below are a few alternative funding methods:

i. Energy Savings Improvement Program (ESIP) – Public Law 2009, Chapter 4

authorizes government entities to make energy related improvements to their facilities and pay for the costs using the value of energy savings that result from the improvements. The “Energy Savings Improvement Program (ESIP)” law provides a flexible approach that can allow all government agencies in New Jersey to improve and reduce energy usage with minimal expenditure of new financial resources.

ii. New Jersey Environmental Infrastructure Trust – The loan program functions as

a trust that allows environmental assistance to projects involving wastewater, drinking water, storm water, landfills, brown fields, open space acquisition, and several others. The program abides by the N.J.A.C. 7:22 - Financial Assistance Programs for Environmental Infrastructure Facilities. For further information regarding the loan process please refer to the following website: www.njeit.org.

iii. Power Purchase Agreement – Public Law 2008, Chapter 3 authorizes contractor

of up to fifteen (15) years for contracts commonly known as “power purchase agreements.” These are programs where the contracting unit (Owner) procures a contract for, in most cases, a third party to install, maintain, and own a renewable energy system. These renewable energy systems are typically solar panels, windmills or other systems that create renewable energy. In exchange for the third party’s work of installing, maintaining and owning the renewable energy system, the contracting unit (Owner) agrees to purchase the power generated by the renewable energy system from the third party at agreed upon energy rates.

iv. Pay For Performance – The New Jersey Smart Start Pay for Performance

program includes incentives based on savings resulted from implemented ECMs. The program is available for all buildings that were audited as part of the NJ Clean Energy’s Local Government Energy Audit Program. The facility’s participation in the program is assisted by an approved program partner. An “Energy Reduction Plan” is created with the facility and approved partner to shown at least 15% reduction in the building’s current energy use. Multiple energy conservation measures implemented together are applicable toward the total savings of at least 15%. No more than 50% of the total energy savings can result from lighting upgrades / changes.

Total incentive is capped at 50% of the project cost. The program savings is broken down into three benchmarks; Energy Reduction Plan, Project Implementation, and Measurement and Verification. Each step provides



additional incentives as the energy reduction project continues. The benchmark incentives are as follows:

1. Energy Reduction Plan – Upon completion of an energy reduction plan by

an approved program partner, the incentive will grant $0.10 per square foot between $5,000 and $50,000, and not to exceed 50% of the facility’s annual energy expense. (Benchmark #1 is not provided in addition to the local government energy audit program incentive.)

2. Project Implementation – Upon installation of the recommended measures

along with the “Substantial Completion Construction Report,” the incentive will grant savings per KWH or Therm based on the program’s rates. Minimum saving must be 15%. (Example $0.11 / kWh for 15% savings, $0.12/ kWh for 17% savings, … and $1.10 / Therm for 15% savings, $1.20 / Therm for 17% saving, …) Increased incentives result from projected savings above 15%.

3. Measurement and Verification – Upon verification 12 months after

implementation of all recommended measures, that actual savings have been achieved, based on a completed verification report, the incentive will grant additional savings per kWh or Therm based on the program’s rates. Minimum savings must be 15%. (Example $0.07 / kWh for 15% savings, $0.08/ kWh for 17% savings, … and $0.70 / Therm for 15% savings, $0.80 / Therm for 17% saving, …) Increased incentives result from verified savings above 15%.

CEG recommends the Owner review the use of the above-listed funding options in addition to utilizing their standard method of financing for facilities upgrades in order to fund the proposed energy conservation measures.



XI. ADDITIONAL RECOMMENDATIONS The following general 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. Use cog-belts instead of v-belts on all belt-driven fans, etc. These can reduce electrical consumption of the motor by 2-5%.

D. Reduce lighting in specified areas where the foot candle levels are above 70 in private offices and above 30 in corridor, lobbies, etc.

E. Provide more frequent air filter changes to decrease overall fan horsepower requirements and maintain better IAQ.

F. Recalibrate existing sensors serving the office spaces

G. Install a Vending Miser system to turn off the vending machines when not in use.

H. Clean all light fixtures to maximize light output.

I. Confirm that outside air economizers on the rooftop units are functioning properly to take advantage of free cooling.



XII. ENERGY AUDIT ASSUMPTIONS The assumptions utilized in this energy audit include but are not limited to following:

A. Cost Estimates noted within this report are based on industry accepted costing data such as RS MeansTM Cost Data, contractor pricing and engineering estimates. All cost estimates for this level of auditing are +/- 20%. Prevailing wage rates for the specified region has been utilized to calculate installation costs. The cost estimates indicated within this audit should be utilized by the owner for prioritizing further project development post the energy audit. Project development would include investment grade auditing and detailed engineering.

B. Energy savings noted within this audit are calculated utilizing industry standard procedures and accepted engineering assumptions. For this level of auditing, energy savings are not guaranteed.

C. Information gathering for each facility is strongly based on interviews with operations personnel. Information dependent on verbal feedback is used for calculation assumptions including but not limited to the following:

a. operating hours b. equipment type c. control strategies d. scheduling

D. Information contained within the major equipment list is based on the existing owner documentation where available (drawings, O&M manuals, etc.). If existing owner documentation is not available, catalog information is utilized to populate the required information.

E. Equipment incentives and energy credits are based on current pricing and status of rebate programs. Rebate availability is dependent on the individual program funding and applicability.

F. Equipment (HVAC, Plumbing, Electrical, & Lighting) noted within an ECM recommendation is strictly noted as a basis for calculation of energy savings. The owner should use this equipment information as a benchmark when pursuing further investment grade project development and detailed engineering for specific energy conservation measures.

Utility bill annual averages are utilized for calculation of all energy costs unless otherwise noted. Accuracy of the utility energy usage and costs are based on the information provided. Utility information including usage and costs is estimated where incomplete data is provided.

Discussion • Total current heating load is 2934 KBTU/Hr (153BTU/Sq ft/Hr)

• NovaThermal heating load is 546.7 KBTU/Hr (29BTU/Sq ft/Hr), which is 20% of the heat that the current

system is delivering to the building.

• The current hot water for heating is approximately 180F. We could provide hot water at a maximum temperature of 160F. If the delivery device has enough heating capacity, this temperature will be sufficient. We assume the delivery system will meet the NovaThermal requirements.

• The cooling calculation utilizes two options: 51 tons and 45 tons. The 45 ton cooling capacity should be sufficient.

• Cooling uses a roof unit through refrigerant coil and AHU. The building requires a new AHU system with a water coil so that hot water and chilled water can be circulated. AHU will have extra cost.

• With redundant settings, the project cost will be increased.
