3 EXECUTIVE SUMMARY The Matawan Borough Hall and Community Center is a single story 43,700-ft 2 facility which contains municipal official s offices, a court room, meeting rooms, cafeteria, kitchen, gymnasium, and a children s day care. The building consists of three distinct sections, the original 1955 construction which borders Church Street, the octagon section which houses the daycare facility which was built in 1969, and the addition and renovation which was constructed in The octagon area is leased to the YMCA. The following chart provides a comparison of the current building energy usage based on the period from October 2012 through September 2013 for electricity and July 2013 through June 2014 for natural gas with the proposed energy usage resulting from the installation of recommended Energy Conservation Measures (ECMs) excluding any renewable energy. Additionally, as fuel oil cost and consumption data was not available for analysis the Current Annual Cost of Energy, Site Energy Use Intensity, Source Energy Use Intensity and Joint Energy Consumption are underestimated.

4 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. Capital improvements may also constitute equipment that is currently being operated beyond its useful lifetime. 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 Improvement measure to reduce energy usage: Consider Installing a Photovoltaic System Replace 1955 Boiler with New Gas Fired Boiler Replace Roof of 1955 Annex Replace City Planning Unit with Heat Pump In addition to these ECMs, SWA recommends the following Operation and Maintenance (O&M) measures that would contribute to reducing energy usage at low or no cost: Install Water-Efficient Fixtures and Controls Purchase Energy Star Appliances There may be energy procurement opportunities for Borough Hall to reduce annual utility costs. The building currently pays a higher than average utility rate for gas, and should be able to further reduce utility costs. SWA recommends further evaluation with energy suppliers, listed in Appendix D. Energy Conservation Measure Implementation The following table shows an estimated implementation timeline for the recommended ECMs at Borough Hall. Est. Implementation Timeline Environmental Benefits Table 2: Estimated Energy Conservation Timeline Savings ($) Simple Payback Period Initial Investment ($) CO2 Savings (lbs/yr) 0-5 Year $5, $17,903 60, Year $1, $10,917 27,842 >10 year $4, $55,442 7,892 Total $12, $84,263 96,580 SWA estimates that implementing the recommended ECMs is equivalent to removing approximately 8 cars from the roads each year or is equivalent of planting 235 trees to absorb CO2 from the atmosphere.

5 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 40-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 Matawan Borough Hall/Community Center on July 14 th 2014, which includes benchmarking and energy bill analysis, assessment of existing conditions, 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 Borough of Matawan to make decisions regarding the implementation of the most appropriate and most costeffective energy conservation measures.

6 HISTORICAL ENERGY CONSUMPTION Energy Usage, Load Profile and Cost Analysis SWA reviewed electric utility bills from September 2012 through September 2013 and gas utility bills from July 2012 through June 2014 that were received from T&M Associates on behalf of the Borough of Matawan. A 12-month period of analysis from October 2012 through September 2013 was used for all calculations regarding electrical energy savings. Similarly, a 12-month period of analysis from July 2013 through June 2014 was used for all calculation regarding natural gas energy savings. For the purposes of benchmarking the building, these periods were treated as though they coincided with one another. Additionally, as no fuel oil bills were provided an analysis could not be completed. As a result, many of the total figures presented for the building are underestimates. This consumption would be solely attributed to the fuel oil fired steam boiler. Electricity The building is currently served by one electric meter, supplied by Direct Energy and delivered by Jersey Central Power and Light. Electricity is predominantly used for lighting, heating equipment, cooling equipment and miscellaneous plug loads. Electricity was purchased at an average aggregated rate of $0.115/kWh and Borough Hall consumed approximately 253,440 kwh, or $29,172 of electricity, for the electric billing analysis period. Monthly demand data was not available for Borough Hall. The chart below shows the monthly electric usage and costs. The dashed green line represents the approximate base load or minimum electric usage required to operate the building. The baseline usage for the facility is approximately 15,767 kwh. The consumption profile seen is typical for a building with similar characteristics as peak consumption occurs in June. It is expected that the building with electric cooling systems experience peak consumption during the summer months. However, the consumption from October and November are below the expected baseline. Building staff should consider investigating this anomalies and future anomalies to verify that the equipment and building systems are operating as expected. Figure 1 Annual Electric Usage and Costs Steven Winter Associates, Inc. - LGEA Report Borough of Matawan Borough Hall/Community Center Page 6/73

7 Figure 2 Electric Consumption and Cooling Degree Day Curves The chart above shows the monthly electricity usage along with the cooling degree days or CDD. Cooling degree days is the difference of the average daily temperature and a base temperature of 50 F, on a particular day. As seen in the chart the building does appear to respond well to cooling degrees. This is shown by a correlation between electricity consumption and cooling degree days. However, the deviation seen in October and November should be investigated. It is recommended that this analysis be performed periodically to provide a meaning of tracking performance with regard to cooling requirements. Steven Winter Associates, Inc. - LGEA Report Borough of Matawan Borough Hall/Community Center Page 7/73

8 Natural Gas The building is served by one natural gas meter, which is supplied by Direct Energy and delivered by New Jersey Natural Gas. Natural gas was purchased at an average aggregated rate of $1.15/therm and Borough Hall consumed 5,080 therms, or $5,841 of natural gas, for the natural gas billing analysis period. The chart below shows the monthly natural gas usage and costs. As expected, usage peaks in the winter months in conjunction with the enabling of heating mode. Consumption of natural gas then continues at a baseline value of 0 therms during the remainder of the year as domestic hot water is provided by an electric water heater. Figure 3 Annual Natural Gas Usage Steven Winter Associates, Inc. - LGEA Report Borough of Matawan Borough Hall/Community Center Page 8/73

9 Figure 4 Natural Gas Usage and Heating Degree Day Curves The chart above shows the monthly natural gas usage along with the heating degree days or HDD. Heating degree days is the difference of the average daily temperature and a base temperature of 65 F, on a particular day. The heating degree days are zero for the days when the average temperature exceeds the base temperature. As expected, the natural gas consumption profile follows a curve similar to the HDD curve. Here we also see that there are little to no anomalies and any variation in consumption from year to year is due to changes in HDD and therefore heating requirements. Fuel Oil The building is delivered fuel oil for use in the steam boiler responsible for heating much of the building. However, fuel oil data consumption was not available at the time of this study and could not be analyzed. Should this information become available SWA recommends analyzing the consumption in a similar fashion as the natural gas analysis above. This will provide the Borough of Matawan with a method of monitoring fuel oil consumption as it should respond to HDDs. The following pie charts and table show energy use for Borough Hall are based on utility bills for the analyzed billing periods. However, as fuel oil consumption data was not available for analysis the pie charts can be misleading. A tag designating the Building Space Heating (Fuel Oil) slice has been included in the table and pie charts but is shown with no value. Additionally, as the totals would be inaccurate without the fuel oil consumption included they have been removed. Note: Electrical cost at $34/MMBtu of energy is more than 3 times as expensive as natural gas at $11/MMBtu.

12 Energy Benchmarking SWA has entered energy information about the building in the U.S. Environmental Protection Agency s (EPA) ENERGY STAR Portfolio Manager energy benchmarking system. This facility is categorized as a Office" space type. However, an ENERGY STAR Energy Performance Rating could not be calculated without the missing fuel oil consumption data. Additionally, Site Energy Utilization Intensity (Site EUI) and Source Energy Utilization Intensity (Source EUI) would be underestimated and inaccurate without the fuel oil data and were not generated. Should this information become available SWA recommends inputting the fuel oil consumption data into the Portfolio Manager system and regenerating a Performance Rating. See the ECM section for guidance on how to further reduce the building s energy intensity. The ENERGY STAR Portfolio Manager uses a national survey conducted by the U.S. Energy Information Administration (EIA). This national survey, known as the Commercial Building Energy Consumption Survey (CBECS), is conducted every four years, and gathers data on building characteristics and energy use from thousands of buildings across the United States. Due to insufficient data in the 2007 survey, Portfolio Manager continues to use data provided by 2003 survey. The Portfolio Manager software uses this data to create a database by building type. By entering the building parameters and utility data into the software, Portfolio Manager is able to generate a performance scale from by comparing it to similar library buildings. This 100 point scale determines how well the building performs relative to other buildings across the country, regardless of climate and other differentiating factors. Figure 7 Monthly Site Energy Intensity Breakdowns per Energy Type (Without Fuel Oil Data) Per the LGEA program requirements, SWA has assisted the Borough of Matawan in creating an ENERGY STAR Portfolio Manager account and sharing the library information to allow future data to be added and tracked using the benchmarking tool. SWA has shared this Portfolio Manager account information with the Borough of Matawan ( ). Steven Winter Associates, Inc. - LGEA Report Borough of Matawan Borough Hall/Community Center Page 12/73

13 Tariff Analysis Tariff analysis can help determine if the Borough Hall 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 Borough Hall. The electric use for the building is direct-metered and purchased under a service rate schedule which includes an annual demand charge, peak summer demand charge and societal benefits charge. The rate schedule 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. Borough Hall is also paying for natural gas under a rate schedule, which includes fixed costs such as customer service charges. Energy Procurement Strategies Utility 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 rate provided by US Energy Information Administration for electric is $0.137/kWh, while Borough Hall pays a rate of $0.115/kWh. The building s annual electric utility costs are $5,549 lower, when compared to the average estimated NJ commercial utility rates. Electric bill analysis shows rate fluctuations up to 9% over the analyzed billing period. The electric rate fluctuations in the winter and spring can be attributed to a combination of demand charges and market rate changes. Borough Hall already utilizes a third-party supplier, which reduces the supply costs and brings the overall electric costs down. Steven Winter Associates, Inc. - LGEA Report Borough of Matawan Borough Hall/Community Center Page 13/73

14 Figure 9 Average NJ Electric Rate, Average Aggregated Electric Rate and Electric Demand The average estimated NJ commercial utility rate provided by US Energy Information Administration for gas is $0.811/therm, while the building pays a rate of $1.15/therm. Borough Hall s annual natural gas costs are $1,721 higher, when compared to the average estimated NJ commercial utility rates. The natural gas rate analysis shows fluctuations up to 319% over the analyzed billing period excluding months where there was no natural gas consumption. These periods are shown in the graph as $0/Therm. Utility rate fluctuations when entering and exiting the heating months were caused by a combination of low usage and the assessment of fixed fees and costs. Steven Winter Associates, Inc. - LGEA Report Borough of Matawan Borough Hall/Community Center Page 14/73

15 Figure 10 Average NJ Gas Rate and Monthly Gas Rates SWA recommends that the building continue utilizing the opportunity of purchasing electricity and natural gas from third-party suppliers in order to maintain the reduced rate. Additionally, SWA recommends that the building further explore opportunities of purchasing natural gas from another third-party supplier to reduce the annual cost of energy for Borough Hall. Appendix D contains a complete list of third-party energy suppliers for Borough Hall s service area.

16 EXISTING FACILITY AND SYSTEMS DESCRIPTION This section gives an overview of the current state of the facility and systems. Please refer to the Proposed Further Recommendations section for recommendations for improvement. Based on a visit from SWA in July 2014, the following data was collected and analyzed. Building Characteristics The Matawan Borough Hall and Community Center is a single story 43,700-ft 2 facility which contains municipal official s offices, a court room, meeting rooms, cafeteria, kitchen, gymnasium, and a children s day care. The building consists of three distinct sections, the original 1955 construction which borders Church Street, the octagon section which houses the daycare facility which was built in 1969, and the addition and renovation which was constructed in The octagon area is leased to the YMCA. There are several functions and end-users of the facility. The municipal offices house the local government employees; a court room is occupied sporadically for various appointments; there exists a gymnasium and cafeteria which houses various events; the YMCA octagon area serves as a child daycare center; the 1955 annex houses several employee offices, a weightlifting gym, classrooms, and storage areas. Image 1: Front Entrance Image 2: 1955 Section Building Occupancy Profiles The Matawan Borough Hall is occupied by approximately 100 people, including staff, teachers, and visitors. The administrative offices are open Monday through Thursday 7:30 a.m. 5:00 p.m.; however the YMCA is open Fridays and on occasional weekends. Building Envelope On July 14, 2014, SWA performed a building envelope analysis. At this time, the average outside dry bulb temperature was approximately 78 F with an average wind speed of 3 mph. The building envelope consists of the outer shell of the building including the walls, windows, doors, and roof. This section will examine the overall condition of the envelope and note any deficiencies discovered during the audit. Steven Winter Associates, Inc. - LGEA Report Borough of Matawan Borough Hall/Community Center Page 16/73

17 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 detailed visual analysis, as far as accessibility and weather conditions allowed at the time of the field audit. Exterior and Interior Walls The exterior construction of the 1955 annex section is comprised mainly of red brick with an unconfirmed level of insulation. Based on the year of construction of the section and staff provided information, SWA estimates that there is little insulation installed in the exterior walls. Because the building has little insulation, the exterior walls likely experience more heat loss. This section was found to be in poor-to-fair condition, with notable areas of uncontrolled moisture and air leakage issues, especially near entry doors, windows, and at the exterior locations of the unit ventilators. There were also several areas of deficient construction on the underside of the roof. However, the exterior and interior wall surfaces of the octagon section and new 2000 addition were also inspected during the field audit. They were found to be in overall fair condition with no signs of uncontrolled moisture, air-leakage, or other energy-compromising issues detected on all facades. Image 3: 1955 Section Exterior Image 4: YMCA Area Exterior Roof The 1955 roof section consists of low-sloped roof and contains exhaust fans. The 2000 addition consists of a flat roof with EPDM membrane, containing exhaust fans and RTUs. The 1969 addition consists of a sloped roof with EPDM membrane. SWA could not confirm the thickness or R-value of the insulation below the roofing material of any section. Roofs, related flashing, gutters and downspouts were inspected during the field audit. Aside from the 1955 annex, the roofs were reported to be in overall good condition with only a few minor leaks. The roof showed evidence of only a small amount of pooling or standing water. It is important to note that pooling water can accelerate deterioration of the roof membrane and allows ice to form in the winter. However, the 1955 annex was found to have large areas of infiltration on the underside of the roof (see image 6) indicating that the roof may be in need of replacement. Steven Winter Associates, Inc. - LGEA Report Borough of Matawan Borough Hall/Community Center Page 17/73

18 Image 5: Roof of 2000 Section Image 6: Decaying Roof Structure of 1955 Section Base The building s base contains no basement level and the entire building is built slab on grade. 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 fair condition with few signs of uncontrolled moisture, air-leakage and/or other energycompromising issues that were neither visible on the interior nor exterior. Windows The buildings windows consist of the following types: 1. Double Pane Windows with Aluminum Frames a section and 1969 section 2. Single Pane Windows with Wooden Frames a section Windows, shading devices, sill, related flashing and caulking were inspected as far as accessibility allowed for signs of moisture, air-leakage, and other energy compromising issues. The windows in the newer sections of the building are double pane for which the caulking and window frames were found to be in good condition. Windows in the 1955 section were found to be in extremely poor condition. Rotting was noted in the wooden frames and many of the glass panes have either cracked or have been replaced with plastic inserts. Windows in this section should be replaced as soon as possible. Exterior Doors The building contains the following exterior doors: 1. Aluminum swing doors, some with large double pane glazing windows and an insulated aluminum doorframe - These doors are located at the entrances of the building in the 2000 and 1969 sections. Many of these doors were installed within the past 10 years and were in good condition. Steven Winter Associates, Inc. - LGEA Report Borough of Matawan Borough Hall/Community Center Page 18/73

19 2. Wooden doors with single pane glass These doors exist in the 1955 section. All are in very poor condition, allowing outside air to infiltrate directly into the space. These should be replaced before the next heating season in order to avoid large heatingenergy use for combatting outside air infiltration. Overall, in the newer section of the building, weather-stripping for the doors was found to be in good condition with only a few signs of air-leakage, with no signs of uncontrolled moisture. Poor weather stripping allows unconditioned air to enter the building, leading to increased energy using for space conditioning. The 1955 Annex section of the building is in need of direct replacement of all doors. Image 7: Aluminum Exterior Doors Image 8: 1955 Doors in Poor Condition Building Air-Tightness During the walkthrough, there were many areas of infiltration noted in the 1955 section, as described in the previous sections. In the newer sections of the building, the field auditors found the building to adequately airtight with a few areas of suggested improvements. 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 and Air Conditioning The primary HVAC system at Borough Hall consists of - one Split-DX unit and one steam boiler serving the YMCA Section; three Split-Dx units, which provide cooling and gas-fired heating, serving the administrative offices and courtroom; window air conditioners and one large fire-tube boiler serve the 1955 annex. Additionally, there is one Heating & Ventilating unit serving the gymnasium. Steven Winter Associates, Inc. - LGEA Report Borough of Matawan Borough Hall/Community Center Page 19/73

20 Equipment Heating Systems Heating for the building is broken into three sections, the YMCA section, the administrative offices, and the 1955 Annex. YMCA The YMCA is served by a 140 MBH Valiant Cast-Iron steam boiler. The boiler was installed in 1994, and has reached the end of its estimated useful life. The boiler efficiency is unknown. The Boiler provides heating steam to the Octagon area, the gymnasium, and to select areas of the 1969 section. The boiler is controlled by temperature sensors located throughout the area. Temperatures are averaged to maintain a desired space temperature. During the walkthrough many of these temperature sensors were found to be non-functional. The space temperature is set back at night and weekends for freeze protection. Administrative Offices Two Gas-fired rooftop units provide heating for the administrative offices for which they serve. Averaging temperature sensors throughout the spaces control the rooftop units in order to maintain desired space temperatures. A central thermostat allows the occupants to adjust the thermostat within a temperature range. The space temperature is set back at night and weekends for freeze protection. The RTU serving the courtroom is only enabled when there is a scheduled event Annex The 1955 annex is served by large Federal Firetube Boiler capable of providing 3,705 lbs of steam per hour. There are no thermostats controlling the boiler. The boiler is manually enabled and disabled according to perceived space temperature. During nights and weekends the boiler remains enabled to prevent freezing. The boiler was installed during the building s original construction, in 1955; boilers have an estimated useful life of 20 years. Cooling Systems Unit Zone Served Heating Capacity RTU #1 Lobby and Administrative Offices 350 MBH RTU #2 Court Room 120 MBH B-1 YMCA/Gym/1969 offices 140 MBH B Annex 3705 lbs/hr Cooling for the building is broken into three sections, the YMCA section, the administrative offices, and the 1955 Annex. YMCA The YMCA is served by an 8.6-ton Split-DX unit which provides cooling to the octagon section of the building. The AC is controlled by temperature sensors located throughout the area. Temperatures are averaged to maintain a desired space temperature, found to be 72 F at the time of visit. During the walkthrough many of these temperature sensors were found to be non-functional. Administrative Offices One 25 Ton RTU provides cooling to the lobby and administrative areas, one 5 ton RTU serves the courtroom, and one 4-ton split unit serves the City Planning Dept. All units are controlled by programmable thermostats, which disable the units during overnight and weekend periods. Steven Winter Associates, Inc. - LGEA Report Borough of Matawan Borough Hall/Community Center Page 20/73

21 1955 Annex The annex is cooled by window AC units located in each room. These are manually controlled by the occupants. Window AC s range from 5 to 24 MBH and have EERs ranging from 9.7 to 10. Unit Tag Zone Served Cooling Capacity AC-YMCA YMCA 8.6 Tons RTU #1 Lobby and Administrative Offices 25 Ton RTU #2 Court Room 5 Ton AC-1 City Planning 4 Tons Window Units 1955 Annex Varies Image 9: 25 Ton RTU Image 10: 1955 Boiler Ventilation Ventilation throughout the facility is provided by exhaust fans and through the rooftop units. There are 19 dedicated exhaust fans serving the office areas, the 1955 annex, kitchen and cafeteria. General exhaust fans operate during occupied hours. Kitchen exhaust fans are manually operated and only enabled when the kitchen is being used for cooking purposes. There is a dedicated Heating & Ventilation unit serving the gymnasium. This is manually controlled by building maintenance personnel and enabled whenever the gym is occupied. Controls Wall mounted temperature sensors throughout the administrative office spaces are averaged by the thermostat in order to control the rooftop unit (RTU) serving the offices in both heating and cooling modes. The small split unit serving the city planning offices is controlled by one thermostat located within the space. Wall mounted temperature sensors throughout the YMCA spaces are averaged by the thermostat in order to control the rooftop unit (RTU) serving the spaces. Many of these temperature sensors were found to have non-working digital displays; it was unknown whether these sensors are operable.

23 Electrical Systems 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. Interior lighting Lighting throughout the building primarily consisted of T8 linear fluorescent fixtures, and compact fluorescent fixtures. However, several spaces including the classrooms in the YMCA portion of the building are lit with inefficient T12 linear fluorescent fixtures. Exit Lights All of the emergency exits signs have been upgraded to LED exit signs, which operate on low wattage and have a long lifespan. Exterior Lighting Lighting along the exterior of the building varied and consisted of metal halide, halogen, and incandescent lamps. Exterior lamps are operated on a timer schedule and are set to activate at 4 pm and disable at 6 a.m. Image 19: Interior T8 Lighting Image 20: 100W Metal Halide Exterior Lamp Other Electrical Systems In addition to the major building system described above, Borough Hall is equipped with a few other electrical systems. This primarily includes kitchen appliances, including cooking equipment, freezers, and refrigerators. There are several other microwaves, coffee machines, and refrigerators throughout the office areas. There is also a packaged pumping system on the 1955 exterior and a refrigerated vending machine in the cafeteria.

24 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 governmentsponsored 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 Certificates (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. Borough Hall appears to be good candidate for a 9 kw solar photovoltaic (PV) system. A structural analysis would be required to determine if the roof could hold a PV system. See the Capital Improvement section for more information. 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 Borough Hall is not a good candidate for wind power generation due to insufficient wind conditions in this area of New Jersey. Geothermal Borough Hall is not a good candidate for geothermal installation since it would require replacement of the entire existing HVAC system, as well as extensive installation of geothermal wells and pumping equipment.

25 Combined Heat and Power Borough Hall 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 constant electrical base load to accommodate the electricity generated, as well as a means for using waste heat generated.

26 PROPOSED ENERGY CONSERVATION MEASURES Energy Conservation Measures (ECMs) are recommendations determined for the building based on improvements over current building conditions. ECMs have been determined for the building based on installed cost, as well as energy and cost-savings opportunities.

These doors have gaps between the doors themselves and the framing, which allows for unwanted air infiltration and heat transfer between conditioned indoor spaces and unconditioned spaces or the outdoors. This results in increased energy to heat and cool the spaces, as well as in the infiltration of air that contains dust and particulates that impact cleanliness and indoor environmental quality. SWA recommends installing durable, high-quality weatherstripping and door sweeps on these doors. Maintenance should inspect doors and frames and repair any damage or misalignment prior to the installation of this measure. An assumed cost of $3.00/Gallon of fuel oil was utilized to determine energy savings for this calculation.

Incandescent lamps, T12 lamps and HID lamps are an inefficient means of lighting a space or the exterior of the building. Modern LED lamps of 9.5 watts can replace a 60 watt incandescent lamp without loss in lumen output or color quality. In addition, LED lamps have lifespans of 50,000 hours, compared with 1,000 to 2,000 hours for incandescent lamps. Similar reductions in wattage and increases in lifespan are experienced when replacing the T12s with T8 and the HID lamps with LED lamps. Using either in-house maintenance staff or a contracted electrician, replace all incandescent lamps, T12 fixtures and HID lamps with an LED and T8 equivalents.

These areas consisted mainly of offices that are used sporadically throughout the day and could show energy savings by having the lights turn off after a period of no occupancy. Typically, occupancy sensors have an adjustable time delay that shuts down the lights automatically if no motion is detected within a set time period. Advanced ultrasonic lighting sensors include sound detection as a means to controlling lighting operation. Using either in-house maintenance staff or a contracted electrician, replace switches with occupancy sensors. If in-house maintenance staff is utilized, the payback will be significantly shortened.

Electricity may not be the most cost-effective way to heat water, as natural gas currently costs significantly less than electricity, per BTU. SWA recommends replacing the electric hot water heater with a gas-fired domestic hot water heater of equivalent size. By heating water with gas instead of electricity, lower per-btu costs can be taken advantage of, $11/MMBTU for gas compared with $34/MMBTU for electricity. Because there exist natural-gas fired appliances within the building it may be easy to route a gas line to the gas-fired domestic hot water heaters.

There is one (1) natural gas fired steam boiler that provides heating for the YMCA section building during the heating season. The boiler has reached the estimated service life. SWA recommends the replacement of existing old and inefficient boilers. Higher efficiency boilers are now available with advanced touch screen control systems. The touch screen technology makes it easier than ever to set up a perfectly synchronized and energy efficient system and allows access to a complete onboard database of real-time operations data and performance history. Boilers can be equipped with a built-in cascading sequencer for up to eight boilers and can deliver up to 12 million BTU/hr heating capacity. In addition, there is capability for full system integration with Modbus communication protocol, as well as the ability to connect with optional software to download and track historical data, including faults, trends and energy consumption. Other standard control features include outdoor reset, three pump control, night setback, hot water generator compatibility and password security. SWA proposes replacing the 1994 Valiant steam boiler, 140,000 BTUH output, 80% efficient, with a higher efficiency boiler, 140,000 BTUH, >90% efficient and latest turndown and reset controls.

39 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. SWA recommends the following capital improvements for Borough Hall. Consider Installing a Photovoltaic System Currently, the building does not use any renewable energy systems. Renewable energy systems such as photovoltaic (PV) panels can offset a portion of the purchased electricity for the building. Power stations generally have two separate electric 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 the 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. The size of the system was determined considering the available roof surface 1,681-ft 2, without compromising service space for roof equipment and safety. This consists of the southern corner of the 1969 section of the building. A PV system could be installed on the square area facing south-west. A commercial panel is capable of providing approximately 12.5 watts per square foot. SWA estimates a 9 kw system can be installed on the roof with an estimated project cost of $55,170. Borough Hall can take advantage of the Solar Renewable Energy Certificates (SRECs) Registration Program, to increase the annual savings. In the program, an SREC is earned for every 1,000 kwh generated by the PV system. The SRECs can then be traded in a market, providing the Borough of Matawan with a new revenue stream which reduces the payback period. The system is estimated to save the building 9,268 kwh in the first year. This was determined using the System Advisor Model software developed by the National Renewable Energy Laboratory ( Assuming an SREC price of $ (December 2013), the project may have a simple payback of 9.06 years. Further investigation would be required to accurately estimate project costs and economic factors that would be used for an implementation decision. The graph below generated by the system Advisor Model software shows the monthly output of the PV system proposed at Borough Hall.

40 Replace 1955 Boiler with New Gas Fired Boiler - The 1955 annex is currently heated using an oil-fired boiler which is original to the building. The boiler was originally a coal-fired boiler, which was upgrade to oil in the 1960 s. The boiler has no thermostatic control and is manually enabled and disabled by maintenance personnel. The boiler likely has a very low efficiency, compared with newer boilers, due to the age and fuel switch which took place. Additionally, without thermostatic control, energy may be wasted in overheating the space and allowing the boiler to run during overnight and weekend hours unnecessarily. While two boilers currently exist, only one is operational. The currently installed boilers are conservatively estimated to be 70% efficient. SWA recommends replacing the boilers with new, gas-fired boilers. New gas-fired steam boilers have efficiencies of approximately 85%. Additionally, the boiler should be controlled using space temperature sensors located in various areas in order to maintain proper temperature. Controls should include a nighttime and weekend setback where space temperature is allowed to drift as low as 40 F to prevent freezing. Detailed fuel oil consumption data would be required to accurately estimate energy savings but it can be estimated that the new boiler without any improvements to controls would save approximately 18% of the total fuel oil consumption. Replace Roof of 1955 Annex - Consider replacing the roof of 1955 annex while adding insulation. During the walkthrough, the roof was found to be in poor condition. The underside of the roof had large gaps and sagging areas that allow outside air and moisture to infiltrate the building. This moisture and air leakage causes further decaying of the roof. In addition, there is likely very little insulation beneath the roof, considering the year of construction. Adding Steven Winter Associates, Inc. - LGEA Report Borough of Matawan Borough Hall/Community Center Page 40/73

41 additional insulation will greatly reduce the amount of energy necessary needed to condition the space. Replace City Planning Unit with Heat Pump - During the walkthrough, occupants in the city planning department in the 1969 section complained of cold conditions occurring during the winter. This condition may be rectified by replacing the outdoor condensing unit with a heat pump unit which is capable of providing both heating and cooling. Heat pumps more efficiently deliver heat to a space than electric resistance heating. 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 address equipment settings or staff operations that, when addressed will reduce energy consumption or costs. Install Water-Efficient Fixtures and Controls Building maintenance 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 address 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. This measure can be conducted by in-house maintenance staff with little investment, and yield a short payback. Purchase Energy Star Rated Appliances - SWA recommends that the building consider purchasing the most energy-efficient equipment, including ENERGY STAR labeled appliances, when equipment is installed or replaced. ENERGY STAR appliances meet stricter standards compared to standard appliances. Stricter standards include exceeding Federal minimum efficiencies and reduced environmental impact.

64 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 breakeven 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 measures (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 3.0%). 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. Steven Winter Associates, Inc. - LGEA Report Borough of Matawan Borough Hall/Community Center Page 64/73

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: Steven Winter Associates, Inc. - LGEA Report Borough of Matawan Borough Hall/Community Center Page 65/73
