3 EXECUTIVE SUMMARY The Premiere Eglise Baptiste Haitienne (PEBH) church is a one-story building with full basement comprising a total conditioned floor area of 3,928 square feet. The original structure was built in approximately the early 1970s, and there have been no major renovations or additions since then. The following chart provides a comparison of the current building energy usage based on the period from June 2009 through June 2010 with the proposed energy usage resulting from the installation of recommended Energy Conservation Measures (ECMs) excluding any renewable energy: Electric Usage (kwh/yr) Table 1: State of Building Energy Usage Gas Usage (therms/yr) Current Annual Cost of Energy ($) Site Energy Use Intensity (kbtu/sq ft /yr) Source Energy Use Intensity (kbtu/sq ft /yr) Joint Site Energy Consumption (MMBtu/yr) Current 13,220 2,179 6, Proposed 11,390 1,903 5, Savings 1, , % Savings Proposed 8,850-7, Renewable Energy *Includes operation and maintenance savings; **Includes SRECS SWA has entered energy information about the residential complex into the U.S. Environmental Protection Agency s (EPA) Energy Star Portfolio Manager Energy Benchmarking system. The building has an Energy Star Rating of 48 out of a possible 100. According to the Energy Star Portfolio Manager software, an average similar building would score a 50 and a high performance building would score a minimum of 75. The PEBH church is a typical church building that contains a simple HVAC system and a small foot print. Based on the size of the building and the limited operational hours, the focus of the recommendations are on envelope issues, equipment replacement and lighting upgrades. One major issue with the building is nonconsistent thermal barrier because of the exterior doors. The best strategy for the building to improve efficiency would be to first, replace necessary exterior doors and weather-strip between the doors and the doorframes for all existing and new doors. Preventing cold air from infiltrating the building through the exterior doors will greatly improved the HVAC system, especially since 2 thermostats are located in proximity to exterior doors and are excessive amounts of heating to overcome the infiltration. After the building is sealed properly, SWA recommends that programmable thermostats are installed and properly programmed for periods of occupancy. Electricity used for lighting can be reduced by simple replacements and retrofits. Lastly, based on the available roof area, the building can install a 7.5 kw roof-mounted, Solar Photovoltaic system to offset electricity use and generate revenue through Solar Renewable Energy Credits. Recommendations Based on the current state of the building and its energy use, SWA recommends implementing the following Energy Conservation Measures: Table 2: Energy Conservation Measure Recommendations ECMs First Year Simple Payback Initial Investment CO2 Savings Savings ($) Period ($) (lbs/yr) 0-5 Year , Year >10 year ,509 2,627 Total 1, ,395 6,319 Proposed Renewable Energy 7, ,500 15,846 In addition to these ECMs, SWA recommends: Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 3/52

4 Capital Investment opportunities measures that would contribute to reducing energy usage but require significant capital resources as well as long-term financial planning o Replace 2 exterior doors with insulated doors Operation and Maintenance (O&M) measures that would contribute to reducing energy usage at low cost not cost o Repair holes in brick facade o Weather-strip doors o Remove obstructions from behind mechanical room door o Create a seal at attic opening in ceiling o Provide water-efficient fixtures and controls o Purchase Energy Star appliances There may be energy procurement opportunities for the PEBH church to reduce annual utility costs, which are $1,613 higher, when compared to the average estimated NJ commercial utility rates. SWA recommends further negotiation with energy suppliers, listed in Appendix C. Environmental Benefits SWA estimates that implementing the recommended ECMs is equivalent to removing approximately 1 car from the roads each year or is equivalent of planting 53 trees to absorb CO 2 from the atmosphere. Energy Conservation Measure Implementation Based on the requirements of the Local Government Energy Audit (LGEA) program, the PEBH must commit to implementing some of these measures, and must submit paperwork to the Local Government Energy Audit program within one year of this report s approval to demonstrate that they have spent, net of other NJCEP incentives, at least 25% of the cost of the audit per building. The minimum amount to be spent, net of other NJCEP incentives, is $2, SWA recommends that the PEBH implement the following Energy Conservation Measures using an appropriate Incentive Programs for reduced capital cost: Recommended ECMs Replace 17 existing bulbs with CFL replacements Install 3 programmable thermostats and setup proper programming for entire building Install a 7.5 kw roof-mounted Solar Photovoltaic System Replace existing 65 gallon DHW water heater with inst.

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 38-year-old architectural/engineering research and consulting firm, with specialized expertise in green technologies and procedures that improve the safety, performance, and cost effectiveness of buildings. SWA has a long-standing commitment to creating energy-efficient, cost-saving and resource-conserving buildings. As consultants on the built environment, SWA works closely with architects, developers, builders, and local, state, and federal agencies to develop and apply sustainable, whole building strategies in a wide variety of building types: commercial, residential, educational and institutional. SWA performed an energy audit and assessment for the Premiere Eglise Baptiste Haitienne (PEBH) at 109 Orange Avenue, Irvington, NJ The process of the audit included facility visit on 12/14/2010, benchmarking and energy bills analysis, assessment of existing conditions, energy modeling, energy conservation measures and evaluating 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 PEBH to make decisions regarding the implementation of the most appropriate and most cost-effective energy conservation measures for the building.

6 HISTORICAL ENERGY CONSUMPTION Energy usage, load profile and cost analysis SWA reviewed utility bills from June 2009 through June 2010 that were received from the utility companies supplying the PEBH with electricity and natural gas. A 12 month period of analysis from July 2009 through June 2010 was used for all calculations and for purposes of benchmarking the building. Electricity - The PEBH is currently served by one electric meter. The PEBH currently buys electricity from PSE&G at an average aggregated rate of $0.272/kWh and consumed approximately 13,220 kwh, or $3,596 worth of electricity, in the previous year. The average monthly demand was 18.3 kw and the annual peak demand was 19.0 kw. The chart below shows the monthly electric usage and costs. The dashed green line represents the approximate baseload or minimum electric usage required to operate the PEBH. The chart above shows a spike in electricity during July 2009 when PEBH had high occupancy and used a large percentage of cooling. Natural gas - The PEBH is currently served by one meter for natural gas. The PEBH currently buys natural gas from PSE&G at an average aggregated rate $1.176 and consumed approximately 2,179 therms, or $2,563 worth of natural gas, in the previous year. The chart below shows the monthly natural gas usage and costs. The green line represents the approximate baseload or minimum natural gas usage required to operate the PEBH. Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 6/52

7 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, on a particular day. The heating degree days are zero for the days when the average temperature exceeds the base temperature. SWA s analysis used a base temperature of 65 degrees Fahrenheit. Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 7/52

8 The following graphs, pie charts, and table show energy use for the PEBH based on utility bills for the 12 month period. Note: electrical cost at $80/MMBtu of energy is more than 6 times as expensive as natural gas at $12/MMBtu. Energy benchmarking SWA has entered energy information about the PEBH in the U.S. Environmental Protection Agency s (EPA) ENERGY STAR Portfolio Manager energy benchmarking system. This religious facility is categorized as a house of worship space type. Based on the Portfolio Manager software, PEBH currently earned a benchmarking score of 48. The benchmark score compares the energy performance of the building to other similar buildings based on common building parameters such as size, use and operating hours. A score of 50 represents an average building with common parameters and a score of 75 or higher represents high performance buildings. The Site Energy Use Intensity is 67 kbtu/sqft/yr compared to the national average of a House of Worship building consuming 65 kbtu/sqft/yr. See ECM section for guidance on how to improve the building s rating. Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 8/52

9 Due to the nature of its calculation based upon a survey of existing buildings of varying usage, the national average for space types is very subjective, and is not an absolute bellwether for gauging performance. Additionally, should the PEBH desire to reach this average there are other large scale and financially less advantageous improvements that can be made, such as envelope window, door and insulation upgrades that would help the building reach this goal. Per the LGEA program requirements, SWA has assisted the PEBH to create an ENERGY STAR Portfolio Manager account and share the facility information to allow future data to be added and tracked using the benchmarking tool. SWA has shared this Portfolio Manager account information with the PEBH (user name of EgliseBaptiste with a password of eglisebaptiste ) and TRC Energy Services (user name of TRC-LGEA ). Tariff analysis Tariff analysis can help determine if the municipality is paying the lowest rate possible for electric and gas service. Tariffs are typically assigned to buildings based on size and building type. Rate fluctuations are expected during periods of peak usage. Natural gas prices often increase during winter months since large volumes of natural gas is needed for heating equipment. Similarly, electricity prices often increase during the summer months when additional electricity is needed for cooling equipment. As part of the utility bill analysis, SWA evaluated the current utility rates and tariffs for the PEBH. The PEBH is currently paying a general service rate for natural gas including fixed costs such as meter reading charges. The electric use for the building is direct-metered and purchased at a general service rate with an additional charge for electrical demand factored into each monthly bill. The general service rate is a market-rate based on electric usage and electric demand. Demand prices are reflected in the utility bills and can be verified by observing the price fluctuations throughout the year. Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 9/52

10 Energy Procurement strategies Billing analysis was conducted using an average aggregated rate which is estimated based on the total cost divided by the total energy usage for each utility over a 12 month period. Average aggregated rates do not separate demand charges from usage, and instead provide a metric of inclusive cost per unit of energy. Average aggregated rates are used in order to equitably compare building utility rates to average utility rates throughout the state of New Jersey. The average estimated NJ commercial utility rates for electric are $0.150/kWh, while PEBH pays a rate of $0.272/kWh. The PEBH annual electric utility costs are $1,613 higher, when compared to the average estimated NJ commercial utility rates. Electric bill analysis shows fluctuations up to 86% over the most recent 12 month period. Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 10/52

11 The average estimated NJ commercial utility rates for gas are $1.550/therm, while the PEBH pays a rate of $1.176/therm. Natural gas bill analysis shows fluctuations up to 56% over the most recent 12 month period. Utility rate fluctuations may have been caused by adjustments between estimated and actual meter readings; others may be due to unusual high and recent escalating energy costs. SWA recommends that the PEBH further explore opportunities of purchasing both natural gas and electricity from third-party suppliers in order to reduce rate fluctuation and ultimately reduce the annual cost of energy for the building. Appendix D contains a complete list of third-party energy suppliers for the PEBH service area. Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 11/52

12 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 visits from SWA on Tuesday, December 14, 2010, the following data was collected and analyzed. Building Characteristics The one-story building (including a full basement) contains a total floor area of 3,928 square feet. PEBH was originally constructed in approximately the early 1970s with no major renovations or additions. It houses a house of worship, office area, small kitchen and an open activity area. Front of building (East) Front-Side Entrance (South) Building Occupancy Profiles The PEBH occupancy can vary greatly as it is mostly used as a house of worship with limited activity space and office use during the weekday. Typically there are 1-2 occupants in the building and as many as approximately 120 occupants during hours of worship. The building is typically occupied from 8am to 4pm, 7 days per week; although, areas of occupation are limited for a majority of the time. The typical hours of service are Sunday 10am 1pm, Tuesday 7pm 9pm, Wednesday 7pm 9 pm and Saturday for 7am 9am. The space within the church is also rented out to local community groups throughout the week. Building Envelope Due to favorable weather conditions (min. 18 deg. F delta-t in/outside and no/low wind); some exterior envelope infrared (IR) images were taken during the field audit. IR technology helps to identify energy-compromising problem areas in a non-invasive way. Exterior Walls The exterior wall envelope is constructed of a 4 brick façade with 2x4 studded walls and sheet rock interior. Based on similar building designs, it is assumed that the above grade portion of the building consists of 6 R-19 insulation. The below grade portion of the building Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 12/52

13 consists of 8 CMU blocks. The finished portion of the basement contains framed interior walls with no insulation. Note: Wall insulation levels could not be verified in the field or on construction plans, and are based upon similar wall types and time of construction. Exterior and interior wall surfaces were inspected during the field audit. They were found to be in overall poor condition with only a few signs of uncontrolled moisture, air-leakage or other energy-compromising issues detected on all facades. The following specific exterior wall problem spots and areas were identified: Roof Excessive hole in brick facade The building s roof is predominantly sloped, trussed roof with asphalt shingles. On the day of the site visit, the roof was not accessible. It is assumed that R-19 fiberglass insulation is laid on the underside of the roof between the trusses. In the ceiling of the worship area, insulation could be observed placed over a scuttle hole for roof plenum access. The insulation over the scuttle hole did not provide an appropriate air barrier to the attic. Improperly sealed scuttle hole to attic space Note: Roof insulation levels could not be verified in the field or on construction plans, and are based upon similar wall types and time of construction. Roofs, related flashing, gutters and downspouts were inspected during the field audit. They were reported to be in overall good, age-appropriate condition, with only a few signs of uncontrolled moisture, air-leakage or other energy-compromising issues. Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 13/52

14 Base The building s base is composed of a 6 concrete below-grade slab and full basement. Below grade exterior walls are constructed of 8 CMU block. There is no detectable slab edge/perimeter insulation. Slab/perimeter insulation levels could not be verified in the field or on construction plans, and are based upon similar wall types and time of construction. 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 acceptable/ age appropriate condition with some signs of uncontrolled moisture, airleakage and/ or other energy-compromising issues detected in some areas inside. Windows The building contains several different types of windows: 1. Double-pane, frosted glass windows located in the front portion of the building in the stairwell leading downstairs 2. Single-pane, stained glass windows with wood frames in the area of worship. 3. Vinyl-framed, double-paned windows with no low-e coating throughout the main floor of the building and office areas. Windows, shading devices, sills, related flashing and caulking were inspected as far as accessibility allowed for signs of moisture, air-leakage and other energy compromising issues. Overall, the windows were found to be in acceptable/ age appropriate condition with only a few signs of uncontrolled moisture, air-leakage and/ or other energy-compromising issues. Exterior doors The building contains several different types of exterior doors: 1. Front doors are decorative metal doors with partial glazing. 2. Side and rear doors are a mix of un-insulated steel or wood doors. In the case of wooden doors, an interior door is used for the exterior door. All exterior doors, thresholds, related flashing, caulking and weather-stripping were inspected for signs of moisture, air-leakage and other energy-compromising issues. Overall, the doors were found to be in acceptable/ age appropriate condition with some signs of uncontrolled moisture, air-leakage and/ or other energy-compromising issues. There are several problems with the existing exterior doors which overall inhibit the building from retaining heat efficiently during the colder months. One recurring problem is that uninsulated doors with little or no weather-stripping are used which do not provide a proper thermal seal for the building. In some cases, interior-type wood doors are used asexterior Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 14/52

15 doors which provides an inadequate seal for the building. On several doors, the hole drilled for placement of the door knob is much larger than the door knob and air is allowed to travel around the knob. In addition to poor exterior door conditions, the mechanical room is also not separated adequately from the basement space. Since the building contains atmospheric gas furnaces, the basement has a fixed louver to allow outside air into the mechanical room for the combustion process. The mechanical room is currently used for storage of chairs and other furniture which prohibits the door from closing between the mechanical room and kitchen area; allowing cold air to infiltrate the building. The following specific door problem spots were identified: Interior Plywood-type un-insulated doors used as exterior doors at side entrance Digital picture (Left)of decorative front doors with single-panel glass and insignificant air leakage between doors and door frame. Infrared picture (Right) of same doors showing heat loss through single-pane glass and around perimeter of doors.

16 Missing weather-stripping revealing gap under front door Building air-tightness Overall the field auditors found the building to be not adequately air-tight with numerous areas of suggested improvements, as described in more detail earlier in this chapter. The air tightness of buildings helps maximize all other implemented energy measures and investments, and minimizes potentially costly long-term maintenance, repair and replacement expenses. Mechanical Systems Heating Ventilation Air Conditioning The PEBH building contains a forced air furnace system in the basement that provides the entire building with heating, cooling and ventilation. Heating and cooling is controlled by a mix of programmable and non-programmable thermostats located throughout the building. Although there are two programmable thermostats, they are operated entirely in manual mode. A simple switch in the mechanical room allows building staff to operate in either heating or cooling mode but not both simultaneously. Equipment The PEBH is heated, cooled and ventilated by 3 separate Whirlpool furnaces that were installed in approximately These furnaces have a combined heating input of 400,000 MBH and an estimated cooling capacity of 8.5 tons of R-22 refrigerant. On the day of the site visit, condensers for the furnaces could not be accessed and therefore capacity is estimated using a typical rule of thumb based on conditioned area. All equipment that was surveyed was observed to be in good operating condition and is not in need of replacement at this time. Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 16/52

17 2 of 3 furnaces located in Mechanical room Outside air louver and intake for furnace system A comprehensive Equipment List can be found in Appendix A. Distribution Systems The central furnace system provides mixed, conditioned air throughout the entire building via ductwork. Return air is ducted back to the furnace, where it is mixed with outside air and then conditioned before being redistributed throughout the building. Each area of the building contains constant volume diffusers to send conditioned air throughout the building and stale air is collected via return air vents in each space. Constant volume diffusers in church area Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 17/52

18 Controls The mechanical room contains a wall-mounted switch that allows the building staff to choose heating or cooling mode but not both simultaneously. Once in the desired mode, the heating and cooling equipment is controlled by 5 wall-mounted thermostats located throughout the entire building; 2 of which are programmable thermostats but are only operated in manual mode. There were several issues with the controls that prohibit the HVAC equipment from conditioning the building efficiently. The programmable thermostats are only used in manual mode, heat settings were set for occupancy even though no occupants were present and clocks are not set properly. Based on the limited number of hours that the building is occupied, the building could benefit greatly from setting the clock and accurately programming these thermostats to reduce setpoints during unoccupied hours. The Trol-a-temp manual thermostat in the back room of the church was not reading temperatures correctly and displayed a temperature of 88F which was not realistic. Manual thermostats near the stairwell on the main floor and near the kitchen in the basement, were set for greater than their setting would allow (>80F) but were reading low temperatures (<50F). These thermostats were affected by cold temperatures caused by un-insulated doors. The thermostat near the stairwell senses cold temperature because an un-insulated interior door is used in place of an exterior door. The thermostat near the kitchen sense cold temperatures because the items used for storage in the mechanical room prevent the door between the kitchen and mechanical room from closing properly. Overall, thermostat settings combined with poor insulation and weather-stripping are causing the building to use more heating than necessary. Domestic Hot Water Domestic Hot Water (DHW) is provided by an AO Smith atmospheric, gas-fired water heater. This unit was installed in 1996 and has reached the end of its useful lifetime. The unit currently has 65 gallons capacity, 32,000 Btuh input and 32.8 gal/hr recovery. This unit (Model #FSG ) uses inefficient combustion technology and should be replaced. 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. As of July 1, 2010 magnetic ballasts most commonly used for the operation of T12 lamps will no longer be produced for commercial and industrial applications. Also, many T12 lamps will be phased out of production starting July Interior Lighting - The PEBH currently contains mostly T12 fluorescent fixtures with magnetic ballasts and single fixtures containing a mix of Compact Fluorescent Lamps (CFLs), halogen flood lights and incandescent bulbs. Based on measurements of lighting levels for each space, there are no vastly over-illuminated areas. Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 18/52

19 Typical T12 fixture with magnetic ballast Typical halogen flood lights used for lighting Exit Lights - Exit signs were found to be a mix of LED and incandescent exit signs. Exterior Lighting There were no exterior lights located at the building. Lighting of the outside areas of the building are reliant on street lighting. Wiring existed for exterior lighting outside of exterior doors, however, these fixtures have been replaced with dummy switch plates. It was observed that the holes drilled through the brick masonry where exterior fixtures previously existed, were much larger than the switch plates that are currently installed. Appliances and process Dummy plates installed in place of exterior lighting. Existing hole is much larger than current plate. SWA has conducted a general survey of larger, installed equipment. Appliances and other miscellaneous equipment account for a significant portion of electrical usage within the building. Typically, appliances are referred to as plug-load equipment, since they are not Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 19/52

20 inherent to the building s systems, but rather plug into an electrical outlet. Equipment such as process motors, computers, computer servers, radio and dispatch equipment, refrigerators, vending machines and printers all create an electrical load on the building that is hard to separate out from the rest of the building s energy usage based on utility analysis. The building contains one Electrolux refrigerator in the kitchen that appears to be Energy Star rated. The kitchen is small and contains no major commercial grade equipment. Elevators The PEBH does not have an installed elevator. Other electrical systems There are not currently any other significant energy-impacting electrical systems installed at the PEBH building. Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 20/52

21 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 Credits (SRECs) that are subsidized by the state government. Specifically, the New Jersey State government pays a market-rate SREC to facilities that generate electricity in an effort to meet state-wide renewable energy requirements. Based on utility analysis and a study of roof conditions, the PEBH is a good candidate for a 7.5 kw Solar Panel installation. See ECM#3 for details. Solar Thermal Collectors Solar thermal collectors are not cost-effective for this building and would not be recommended due to the insufficient and intermittent use of domestic hot water throughout the building to justify the expenditure. Wind The PEBH is not a good candidate for wind power generation due to insufficient wind conditions in this area of New Jersey. Geothermal The PEBH is not a good candidate for geothermal installation based on the small building size and it would require extensive replacement of and additions to the existing HVAC system. Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 21/52

22 Combined Heat and Power The PEBH is not a good candidate for CHP installation and would not be cost-effective due to the size and operations of the building. Typically, CHP is best suited for buildings with a high electrical baseload to accommodate the electricity generated, as well as a means for using waste heat generated. Typical applications include buildings with an absorption chiller, where waste heat would be used efficiently. Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 22/52

23 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. Recommendations: Energy Conservation Measures ECM# Description of Highly Recommended 0-5 Year Payback ECMs 1 Replace 17 existing bulbs with CFL replacements Install 3 programmable thermostats and setup proper programming for entire 2 building Description of Recommended 5-10 Year Payback ECMs 3 Install a 7.5 kw roof-mounted Solar Photovoltaic System Description of Recommended >10 Year Payback ECMs 4 Replace existing 65 gallon DHW water heater with condensing unit 5 Replace or Retrofit 24 fluorescent T12 light fixtures with T8 retrofit kits and electronic ballasts 6 Install 16 infrared, wall-mounted occupancy sensors In order to clearly present the overall energy opportunities for the building and ease the decision of which ECM to implement, SWA calculated each ECM independently and did not incorporate slight/potential overlaps between some of the listed ECMs (i.e. lighting change influence on heating/cooling.

The existing lighting consists of a mix of T12 fluorescent lighting with magnetic ballasts and a mix of Incandescent bulbs, CFL bulbs and halogen flood lights. SWA recommends replacing all incandescent bulbs better performing CFL bulbs. Halogen flood lamps should also be replaced with more efficient reflective CFL fixtures that provide a better quality light while using less energy. Installation cost: Net estimated installed cost: $136 (includes $41 of labor) Source of cost estimate: RS Means; Published and established costs, NJ Clean Energy Program Assumptions: SWA calculated the savings for this measure using measurements taken the days of the field visits and using the billing analysis. SWA verified that lighting levels were accurate for all spaces. Rebates/financial incentives: NJ Clean Energy Direct Install program (Up to 60% of installed cost) Please see Appendix F for more information on Incentive Programs.

SWA recommends replacing the 3 non-programmable thermostats with programmable thermostats capable of reducing temperature setpoints to non-occupied conditions based on a fixed schedule. The existing programmable thermostats were not programmed, but should be aligned with the programming of the new installed thermostats. This measure should be completed after envelope related issues are addressed. Two of the thermostats are not working properly because they are located near areas that are allowing excessive infiltration of cold air through un-insulated doorways. As a result, the thermostat has to be set above its physical limit and an excessive amount of heat is used to overcome the heat loss through these un-insulated areas.

26 ECM#3: Install a 7.5 kw roof-mounted Solar Photovoltaic System Currently, the PEBH does not use any renewable energy systems. Renewable energy systems such as photovoltaic (PV) panels can be mounted on the building roof facing south which can offset a portion of the purchased electricity for the building. Power stations generally have two separate electrical charges: usage and demand. Usage is the amount of electricity in kilowatt-hours that a building uses from month to month. Demand is the amount of electrical power that a building uses at any given instance in a month period. During the summer periods, electric demand at a power station is high, due to the amount of air conditioners, lights, and other equipment being used within the region. Demand charges increase to offset the utility s cost to provide enough electricity at that given time. Photovoltaic systems offset the amount of electricity used by a building and help to reduce the building s electric demand, resulting in a higher cost savings. Installing a PV system will offset electric demand and reduce annual electric consumption, while utilizing available state incentives. PV systems are modular and readily allow for future expansions. The size of the system was determined considering the available roof surface area, without compromising service space for roof equipment and safety, as well as the facilities annual base load and mode of operation. A PV system could be installed on a portion of the roof with panels facing South as shown in the photo below. A commercial multi-crystalline 230 watt panel has 17.5 square feet of surface area (providing watts per square foot). A 7.5 kw system needs approximately 33 panels which would take up 578 square feet. Area in red highlights maximum available area for recommended Solar PVsystem A PV system would reduce the building's electric load and allow more capacity for surrounding buildings as well as serve as an example of energy efficiency for the community. The building is not eligible for a residential 30% federal tax credit. The building owner may want to consider applying for a grant and / or engage a PV generator / leaser who would install the PV system and then sell the power at a reduced rate. In addition to generating electricity in order to offset building electric use, the Solar PV would allow the building to earn Solar Renewable Energy Credits Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 26/52

28 21 2, , , , , , , , , ,407 Assumptions: SWA estimated the cost and savings of the system based on past PV projects. SWA projected physical dimensions based on a typical Polycrystalline Solar Panel (230 Watts, Model ND-U23-C1). PV systems are sized based on 230 Watts and physical dimensions for an array will differ with the efficiency of a given solar panel (W/sq ft). Rebates/financial incentives: NJ Clean Energy - Solar Renewable Energy Certificate Program. Each time a solar electric system generates 1,000kWh (1MWh) of electricity, a SREC is issued which can then be sold or traded separately from the power. The buildings must also become net-metered in order to earn SRECs as well as sell power back to the electric grid. A total of $5,310/year, based on $600/SREC, has been incorporated in the above costs for a period of 15 years; however it requires proof of performance, application approval and negotiations with the utility.

A combustion efficiency test was performed and showed that the current combustion efficiency is 78.1% efficient. Based on the limited use of domestic hot water in the building, SWA recommends installing an instantaneous and condensing, gas-fired heater with similar capacity. The existing unit must constantly keep 65 gallons of domestic hot water maintained at a temperature of 120F. Installing a condensing unit will not only raise the efficiency to at least 94% but it will also reduce the need to heat a large volume of water constantly.

The existing lighting consists of mostly T12 fluorescent fixtures with magnetic ballasts and some T8 fluorescent fixtures with electronic ballasts. SWA recommends replacing each fixture with a newer T8 fluorescent fixture with electronic ballasts. In cases where the fixture contains more than 2 fluorescent lamps, SWA recommends using a retrofit kit that is cheaper to install uses the same shell of the lighting fixture. Based on the audit, there was only 1 fixture that would be applicable for a retrofit. A fluorescent T8 fixture with electronic ballasts typically uses 30% less energy than an equivalent T12 fixture with magnetic ballasts and also provides a better quality light.

The existing lighting consists of linear fluorescent fixtures and a mixture of CFLs, incandescent bulbs and halogen flood lamps. In order to reduce energy used for lighting, SWA recommends installing infrared, wall-mounted occupancy sensors in 16 different areas in the building. The PEBH building is used for limited hours throughout the week and rented out to community groups. To ensure that lights are not left on for extended periods of time, occupancy sensors should be installed for some of the lighting. Occupancy sensors are not recommended for the main church area but mostly smaller rooms such as bathrooms, the band room and kitchen.

32 PROPOSED FURTHER RECOMMENDATIONS Capital Improvements Capital Improvements are recommendations for the building that may not be cost-effective at the current time, but that could yield a significant long-term payback. These recommendations should typically be considered as part of a long-term capital improvement plan. Capital improvements should be considered if additional funds are made available, or if the installed costs can be shared with other improvements, such as major building renovations. SWA recommends the following capital improvements for the PEBH building: Replace 2 exterior doors with insulated doors The side entrances use interior type doors used for external use and do not form a proper thermal seal to the outside. SWA recommends that properly insulated, exterior doors are installed that properly fit to the doorway. 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. Repair holes in brick façade There were several instances of holes in the brick façade where exterior light fixtures were once located. SWA recommends that these holes are repaired properly in order to form a proper moisture and thermal barrier consistent with the wall construction. Weather-strip doors SWA recommends repairing or replacing all weather-stripping on exterior doors and ensure that any new exterior doors installed have a proper seal. Large openings were observed around all doors and cold air was allowed to infiltrate the building. Remove obstructions from behind mechanical room door The mechanical room door is currently not allowed to close all the way because of items that are placed in the mechanical room for storage. This door should form a tight seal and prevent cold air from infiltrating the kitchen from the mechanical room. The cold air from this doorway is affecting the nearby thermostat for the kitchen and causing the building to use an excessive amount of heat. Create a seal at attic opening in ceiling The scuttle hole to access the attic from the ceiling in the main Church area is currently not sealed. It was observed that there is R-19 foil-faced insulation placed throughout the attic and on top of the scuttle hole, however the insulation only forms a loose seal. To prevent warm air from escaping into the attic and out through the building, a seal should be placed at this opening and the insulation barrier should be maintained. Provide water-efficient fixtures and controls - Adding controlled on/off timers on all lavatory faucets is a cost-effective way to reduce domestic hot water demand and save water. Building staff can also easily install faucet aerators and/or low-flow fixtures to reduce water consumption. There are many retrofit options, which can be installed now or incorporated as equipment is replaced. Routine maintenance practices that identify and quickly address water leaks are a low-cost way to save water and energy. Retrofitting with more efficient water-consumption Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 32/52

33 fixtures/appliances will reduce energy consumption for water heating, while also decreasing water/sewer bills. SWA recommends that the building considers purchasing the most energy-efficient equipment, including ENERGY STAR labeled appliances, when equipment is installed or replaced. More information can be found in the Products section of the ENERGY STAR website at: Note: The recommended ECMs and the list above are cost-effective energy efficiency measures and building upgrades that will reduce operating expenses for the PEBH building. Based on the requirements of the LGEA program, Premier Eglise Baptiste Haitienne must commit to implementing some of these measures, and must submit paperwork to the Local Government Energy Audit program within one year of this report s approval to demonstrate that they have spent, net of other NJCEP incentives, at least 25% of the cost of the audit (per building). The minimum amount to be spent, net of other NJCEP incentives, is $2, Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 33/52

44 APPENDIX E: GLOSSARY AND METHOD OF CALCULATIONS Net ECM Cost: The net ECM cost is the cost experienced by the customer, which is typically the total cost (materials + labor) of installing the measure minus any available incentives. Both the total cost and the incentive amounts are expressed in the summary for each ECM. Annual Energy Cost Savings (AECS): This value is determined by the audit firm based on the calculated energy savings (kwh or Therm) of each ECM and the calculated energy costs of the building. Lifetime Energy Cost Savings (LECS): This measure estimates the energy cost savings over the lifetime of the ECM. It can be a simple estimation based on fixed energy costs. If desired, this value can factor in an annual increase in energy costs as long as the source is provided. Simple Payback: This is a simple measure that displays how long the ECM will take to break-even based on the annual energy and maintenance savings of the measure. ECM Lifetime: This is included with each ECM so that the owner can see how long the ECM will be in place and whether or not it will exceed the simple payback period. Additional guidance for calculating ECM lifetimes can be found below. This value can come from manufacturer s rated lifetime or warranty, the ASHRAE rated lifetime, or any other valid source. Operating Cost Savings (OCS): This calculation is an annual operating savings for the ECM. It is the difference in the operating, maintenance, and / or equipment replacement costs of the existing case versus the ECM. In the case where an ECM lifetime will be longer than the existing measure (such as LED lighting versus fluorescent) the operating savings will factor in the cost of replacing the units to match the lifetime of the ECM. In this case or in one where one-time repairs are made, the total replacement / repair sum is averaged over the lifetime of the ECM. Return on Investment (ROI): The ROI is expresses the percentage return of the investment based on the lifetime cost savings of the ECM. This value can be included as an annual or lifetime value, or both. Net Present Value (NPV): The NPV calculates the present value of an investment s future cash flows based on the time value of money, which is accounted for by a discount rate (assumes bond rate of 3.2%). Internal Rate of Return (IRR): The IRR expresses an annual rate that results in a break-even point for the investment. If the owner is currently experiencing a lower return on their capital than the IRR, the project is financially advantageous. This measure also allows the owner to compare ECMs against each other to determine the most appealing choices. Gas Rate and Electric Rate ($/therm and $/kwh): The gas rate and electric rate used in the financial analysis is the total annual energy cost divided by the total annual energy usage for the 12 month billing period studied. The graphs of the monthly gas and electric rates reflect the total monthly energy costs divided by the monthly usage, and display how the average rate fluctuates throughout the year. The average annual rate is the only rate used in energy savings calculations. Steven Winter Associates, Inc. - LGEA Report Premiere Eglise Baptiste Haitienne Page 44/52

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 Premiere Eglise Baptiste Haitienne Page 45/52
