Common Energy Conservation Measures (ECM's) <br />The following table lists commonly reported and recommended Energy Conservation Measures (ECM's) for entities fhroughout the state. The informaGon was derived from the S612 <br />entity annual repoR narratives, Preliminary Energy Assessments (PEA's) conducted by SECO, and with the assistance of SECO engineering contractors.

This global network signal feature <br />Management Software <br />equipment) <br />Per machine <br />activates the Power Saver feature of the PC. Libraries and City <br />Halls are common facilities to utilize this measure. <br />These systems can be integrated into facility operations to <br />efficiently manage multiple systems to achieve the highest energy <br />efficiency. These measures commonly entail an upgrade and <br />Energy Management and <br />Control Systems <br />$a,000 - <br />$160,000 <br />6-16 yrs <br />s°o - 15°o <br />integration of existing thermostats into the energy management <br />system or an upgrade of outdated energy management systems. <br />City Halls, Police Departments and Jails are common facilities to <br />utilize this measure. <br />Vending machine economizers are simple devices similar to <br />lighting-related occupancy or motion sensors which are compatible <br />Vending Machine <br />$100-$2so <br />1.3 -3.3 yrs <br />$30 -$75 <br />With most vending machines.

This can be done with <br />Occupancy Based Settings <br />$200-$250 <br />10 - 20 y`s <br />$50 <br />existing programmable thermostats or through manual settings. City <br />and Controls <br />(per thermostat) <br />per thermostat <br />Halls, Police Departments, Offices and Community Centers are <br />common facilities to utilize this measure. <br />This measure can vary greatly in cost and savings depending on <br />the application and existing conditions of the current HVAC system. <br />S3,400 - <br />° <br />° <br />This measure typically includes upgrades and replacements of <br />System Retrofits <br />$200,000 <br />5.5-16.6 yrs <br />s <br />io - 1a <br />io <br />window units, spot coolers, chillers and cooling towers with split <br />system heat pumps. Fire Stations, Police Stations, City Halls, Jails <br />LIGHTING <br />and Courthouses are common facilities to utilize this measure. <br />This measure typically involves replacing magnetic ballasts which <br />house T-12 lighting with high efficiency 28-watt electronic T-28 <br />Ballast 1 Fixture <br />Replacement <br />$300 -$100,000 <br />10 - 12.5 yrs <br />a%- 1o°io <br />ballasts which house modern higher efficiency lighting. Offices, <br />Community Centers and Jails are common facilities to utilize this <br />measure. <br />This measure varies depending on the ballast type, but typically <br />Bulb Replacement <br />S100 -$5,000 <br />1.3-6yrs <br />is°io-79% <br />involves replacing existing bulbs with the bulbs with the highest <br />available efficienc . <br />This measure involves the integration of natural lighting into <br />facilities to supplement the lighting needs of the facility. Such <br />measures can work as a retrofit project and as design specifications <br />Day Lighting Control <br />$6,000 -$15,000 <br />8.3 -14.3 yrs <br />7% -12% <br />for facilities. It can also integrate an automated system that varies <br />lighting production based on actual lighting needs for the facility and <br />thus can be a costl ex ense. <br />This measure typically involves replacing high pressure sodium or <br />Street Light Bulb <br />$400 -$1,20o <br />z- a yrs <br />ao% <br />mercury vapor street lighting with high efficiency metal halide <br />Replacement <br />lighting. Other lighting technology such as convection lighting may <br />be a feasible consideration for arkin lot and other a lications. <br />Y ~ <br />
