City Marina Building ECM 1 Comprehensive Lighting System Conversion: The scope of this work includes the retrofit/replacement of the existing lighting system in the City Marina Building. ECM 2 Provide a New Programmable Thermostat The project scope of work is to install a new programmable thermostat in the City Marina Building. City Marina Bathhouse ECM 1 Comprehensive Lighting System and Lighting Controls Conversion The scope of this work includes the retrofit of the existing interior lighting system in the Marina Bathhouse. Interior lighting controlled by manual switches will be updated to automated occupancy sensor controls in select areas. ECM 2 Comprehensive Water Conversion The scope of this work includes the replacement of less efficient water closets, flush valves, shower heads and sink aerators with new efficient types. City of Marathon 4 January 6, 2012

9 Community Park ECM 1 Comprehensive Lighting System and Lighting Controls Conversion: The scope of this work includes the retrofit of the existing exterior HID decorative acorn lighting and the retrofit of the existing interior lighting systems in the Community Park administrative building, concession stand building, and Amphitheater storage rooms. Interior lighting controlled by manual switches will be updated to automated occupancy sensor control in select areas. ECM 2 Provide New Programmable Thermostats The project scope of work is to install new programmable thermostats. Teen Center ECM 1 Lighting System Conversion The scope of this work includes the replacement and retrofit of the existing interior and exterior lighting systems in the Teen Center. Interior lighting controlled by manual switches will be updated to automated occupancy sensor control in select areas. ECM 2 Comprehensive Water Conversion The scope of this work includes the replacement of older water closets, flush valves, and sink aerators with new efficient types. Jesse Hobbs Park ECM 1 Comprehensive Lighting System Conversion The scope of this work includes the replacement/ retrofit of the existing exterior lighting at the Jesse Hobbs Park Community Center. Sombrero Beach Road and Turtle Lighting ECM 1 Retrofit Existing HID lighting with new LED lighting The scope of this work includes the retrofit of the existing 133 HID decorative lights and 9 HID turtle lights with new energy efficient LED lighting. City of Marathon 5 January 6, 2012

10 ADDITIONAL RECOMMENDATIONS FOR IMPLEMENTATION In addition to the recommended ECM s listed above there are several other recommendations that should be implemented throughout the City due to equipment failure or ease of maintenance which do not necessarily have substantial energy savings or a favorable return on investment. They are as follows: Sombrero Beach Road Lighting: Relocate the existing lighting fuses and surge protection from the in ground hand hole to inside the light pole base. Many of the 133 hand holes are exposed to standing water for long periods of time. The fuses are not meant to be submerged indefinitely and many of them have failed. This has become a huge maintenance problem for the City and should be addressed. Sombrero Pavilions: Provide new exhaust fan to replace existing non-operable fans in both pavilion restrooms. In addition, the existing wall mounted occupancy sensors controlling the lights in each of the pavilion restrooms are broken. It is recommended that these be replaced with maximum 30 minute timer switches that are more durable than the occupancy sensors. Community Park: Install new disconnect switch adjacent to vendor service located beside the Amphitheater. The service is rarely utilized by anyone. This service has a 150kVA step down transformer that is constantly energized and non-loaded. The estimated savings is approximately $60 per month if the transformer is continuously shut off. City of Marathon 6 January 6, 2012

11 NON-RECOMMENDED ENERGY CONSERVATION MEASURES Other energy conservation measures were evaluated for implementation at these sites but are not recommended. The following presents a brief listing of potential energy conservation measures that were considered for implementation. City Hall ECM Install Comprehensive Lighting System Conversion The scope of this work includes the retrofit/replacement of the existing lighting system in the City Hall buildings. However, due to the low hours of operation and high first cost this measure does not generate an acceptable return on investment. ECM Replace Existing HVAC Units w/ New High Efficiency Units The scope of this work includes the replacement of all the wall mounted Bard units with new high efficiency units. This measure was not recommended because these trailers are not scheduled to be in service after the new City Hall is constructed in a few years and the payback for the new units would greatly exceed this time frame. ECM Install Roof Insulation The scope of work for this measure is to double the thickness of the existing roof insulation, which greatly increases the overall R-value of the facility. However, the capital cost of this measure does not generate sufficient savings to have a favorable return on investment. ECM Comprehensive Water Conversion The scope of work for this measure includes the replacement of less efficient water closets, flush valves, and sink aerators with new efficient types. However, the capitol cost of this measure compared to the savings and payback does not yield a favorable return on investment. Fire Station 14 ECM Replace Existing HVAC Units w/ New High Efficiency Units The project scope of work is to replace the two air-cooled condensing units with new high efficiency units. Due to the relatively young age of the equipment, this measure would not yield an acceptable return on investment. ECM Comprehensive Water Conversion The scope of work for this measure includes the replacement of less efficient water closets, flush valves, and sink aerators with new efficient types. However, the capitol cost of this measure compared to the savings and payback does not yield a favorable return on investment. ECM Replace Existing Hot Water Heater with Electric Heat Pump The scope of this measure is to install an electric heat pump hot water heating system in the fire station facility. The return on investment of this measure does not meet acceptable levels due to the low usage profile and increased maintenance required. City of Marathon 7 January 6, 2012

12 ECM Provide VFD s on Existing Air Handler Units The scope of this measure would be to install Variable Frequency Drives (VFDs) and associated control points on the existing variable volume air-handling units. The capital required to complete this project relative to the savings that would be generated yields an unacceptable return on investment. Community Park ECM Replace Existing HVAC units with High Efficiency Window Units The scope of this work includes the replacement of all the window mounted units at the park with new high efficiency units. This measure was not recommended due to the relatively high first cost compared to the savings. ECM Comprehensive Water Conversion The scope of work for this measure includes the replacement of less efficient water closets, flush valves, and sink aerators with new efficient types. However, the capitol cost of this measure compared to the savings and payback does not yield a favorable return on investment. City Marina Bathhouse ECM Replace Existing Hot Water Heater with Electric Heat Pump The scope of this measure is to install an electric heat pump hot water heating system in the marina facilities. The return on investment of this measure does not meet acceptable levels due to the low usage profile and increased maintenance required. Teen Center ECM Replace Existing HVAC Units with New High Efficiency Unit The scope of work includes the replacement of the oldest air-conditioning unit with new high efficiency unit. The unit would be provided with a new programmable thermostat. This measure was not recommended due to the relatively high first cost compared to the savings. Jesse Hobbs Park No Measures City of Marathon 8 January 6, 2012

13 Sombrero Beach Road Lighting and Pavilions ECM Install Solar Powered Lighting System The scope of this work includes replacing the existing 133 HID lights with a solar powered lighting system. Due to the physical constraints for photovoltaic panels and battery cabinets and a high cost of materials, this project does not generate an acceptable payback for the City. ECM Comprehensive Water Conversion The scope of work for this measure includes the replacement of less efficient water closets, flush valves, and sink aerators with the most efficient types. However, the capitol cost of this measure compared to the savings and payback does not yield a favorable return on investment. 33 rd Street Boat Ramp Restrooms ECM Comprehensive Water Conversion The scope of work for this measure includes the replacement of less efficient water closets, flush valves, and sink aerators with new efficient types. However, the capitol cost of this measure does not yield a favorable return on investment. City of Marathon 9 January 6, 2012
