All present usage and savings information are estimates. Lime Energy provides no warranty, either expressed or implied, as to theaccuracy of the energy distribution, savings or application of any material, product, or procedure.The preparation of this report was financed by an Energy Efficiency and Conservation Block Grantprovided to the County of Allegheny by the U.S. Department of Energy made possible by the AmericanRecovery and Reinvestment Act of 2009.
69 - MCCANDLESS TOWNSHIP1.0ACEPMEXECUTIVE SUMMARYAllegheny County Energy Program contracted with Lime Energy Consulting & Technical Services toperform a targeted energy audit in order to assess the financial benefits of upgrading the AlleghenyCounty facilities with more efficient equipment and systems. The study included the facilities at theMcCandless Township. Lime Energy engineers visited the location and performed an audit earlier thisyear. Utility incentives may be available for some of the ECMs proposed. Where available, theincentive amount has been estimated and is included in the Summary Table. The programs may changefrom the current offerings.1.1ECMIDRECOMMENDED ENERGY CONSERVATION MEASURES ved (kgal.)EstimatedCost SavingsEstimatedECM CostRebatePayback(Yrs.)1.0Lighting Retrofit18.749,95200 4,700 19,695 0 3,509 29,461 08.44.2Insulation0.0030.0 3 32 012.76.0Water Conservation0.004815.6 144 574 04.018.766,4982,00315.6 8,356 49,763 6,3165.2Total Energy ProgramEconomics:Table 1: Summary of Recommended ECM SavingsCONFIDENTIAL1
69 - MCCANDLESS TOWNSHIP2.0ACEPMBUILDING INFORMATIONThe McCandless Township building is located at 9955 Grubbs Rd, Wexford, PA 15090. The building is a2-story commercial office structure built in 1959, (approximately 13,000 square feet) and expandedwith a 5,320 square feet addition in 1993 for a total of 18,320 square feet. Its operating hours areweekdays from 9AM-5PM. This building houses the police department on the first level and theadministrative, building, and zoning, and fire department offices in the second level. There isapproximately 6 officers on duty every shift and 25 employees that work at the municipal building.The Public Works building is located adjacent to the municipal building and was briefly inspected duringthe audit. The Public Works building houses the public works vehicles and offices, along with storagefor other tools and equipment. The public works building is approximately 6,000 square feet. Thereare about 20 employees at the public works that are transiently in the building during the day.2.1BUILDING DESCRIPTIONThe McCandless municipal building is made of concrete block with brick overlay and has a flat rubbermembrane rooftop. The building is conditioned by five main RTUs (3 Bryants, 1 Lennox, 1 Carrier),which supply heating and cooling to the building, with two small Mitsubishi split system units whichserves small offices/server rooms. The building also has supplemental radiator wall heaters whichreceive heating water from the 636,000 BTUh Harsco Industries Patterson-Kelley Modu-Fire forceddraft gas-fired boiler. The wall radiators have thermostats that are separate from the RTUs and aremanual Honeywell thermostats. The thermostats that control the RTUs are usually programmablethermostats and are set at 68 F heating, 74 F cooling.There are two Modine DFG/DFP100 (100,000 Input BTUh, 80,000 Output BTUh, 3704 CFM) furnaces inthe police garage. They are currently controlled by a switch and it is recommended that a timer and/ora thermostat with a 50 F setpoint be installed.The municipal building has a mixture of T8 and T12 4-ft linear fluorescent lamps. It is recommendedthat all lighting fixtures be upgraded to T8 fluorescent lamps and compact fluorescents. Lightingcontrols with motion sensors are also recommended in private offices and seldomly used areas.The restroom fixtures at the facility are currently standard (1.6 gpf toilets, 1.0 gpf urinals). It isrecommended that they be changed to water-efficient fixtures.The Public Works building has six Space-Ray LTS140 tube heaters which heat the garage areas and aLennox RTU unit which provides heating and cooling to the office areas. The lighting fixtures areprimarily T12 fluorescent and incandescent lighting and should be replaced with T8 fluorescent andcompact fluorescent lighting.CONFIDENTIAL2

69 - MCCANDLESS TOWNSHIP3.0ACEPMENERGY CONSERVATION MEASURESThis section outlines our findings and recommendations for improving the energy efficiency of thefacilities. The energy conservation recommendations focus on equipment upgrade opportunities forlighting, HVAC systems, improved controls, and water conservation, as applicable in this building.ECM 1.0 Lighting System UpgradesGeneral Project ScopeLime Energy auditors conducted a lighting survey of all interior and exterior lights in McCandlessTownship, as applicable. Existing lighting systems were surveyed for retrofit opportunities. As a result,old technologies such as fluorescent T12 lamps and magnetic ballasts, high-intensity discharge (HID)fixtures, and incandescent lamps were considered for retrofit to more efficient energy efficienttechnologies. Energy efficient compact fluorescents, and T8 or T5 linear fluorescent lamps and ballasts,were identified as replacements using low wattage lamps, electronic ballasts, and retrofit kits.Opportunities to upgrade to LED technology were identified where applicable.Assumptions for Current Operating Conditions The lamps, ballasts and fixtures targeted for retrofit are listed in the lighHng table in theappendix, including quantity, type, wattage, and operating hours.Assumptions for Proposed Operating Conditions The proposed upgrades are shown in the lighHng table in the appendix, along with anychanges to the current conditions.Implementation Approach The lighHng system may be upgraded by a qualified contractor. For opHmal return oninvestment, conducting a comprehensive upgrade of the fixtures as listed is recommended.Projected Annual Energy ngsInitialCostPaybackE-kWE-kWhP-kWP-kWhS-kWS-kWh Years47123,7902973,8381949,9524,70019,6952.84

69 - MCCANDLESS TOWNSHIP5.0ACEPMADDITIONAL MEASURESThis section outlines additional recommendations for improving the energy efficiency of the facilities;however, the energy conservation measures found might not be feasible or cost effective in thisbuilding.ECM 2.6 Premium Efficiency MotorsGeneral Project ScopeThe motors furnished for older HVAC system fans and pumps are inefficient compared to newpremium efficiency motors available. Replacing the older motors with premium efficiency models wereexplored for this facility; however, due to low runtime hours and small existing motor sizes, the savingsassociated with this measure does not fit with this particular program.Premium efficiency motors are specified by motor manufacturers to meet NEMA standards. Energysavings will be achieved by reducing the energy required for the supply fans serving 5 Municipalbuilding RTUs, 2 Municipal building Mitsubishi split systems and 1 Public Works building roof top airhandler units.Assumptions for Current Operating Conditions Baseline motor energy consumpHon was based on the equipment informaHon collected duringthe building survey, and occupancy schedules provided by the occupants. ExisHng motor efficiencies are from the State of Pennsylvania Act 129 Technical ResourceManual.Assumptions for Proposed Operating Conditions The proposed motor efficiencies are from State of Pennsylvania Act 129 Technical ResourceManual.Implementation Approach The motors are recommended to be replaced by a qualified electrician.Projected Annual Energy WhS-Therms 8
