Glossary Of Terms <br />HVAC Industry standard abbreviation for Pleating, Ventilating and Air Conditioning. <br />kW Kilowatt; a unit of electrical power, equal to 1000 watts. <br />kWh Kilowatt hours; a unit of electrical energy or work, equal to that done by one <br />kilowatt acting for one hour. <br />Load Factor The percentage of time that a piece of equipment operates at full toad over <br />a measured time period. (i.e. Lights that are operated at 100% Load Factor. <br />Refrigerators, on the other hand, operate at less than 100% load based on <br />internal and external temperatures while also cycling on & off as needed to <br />maintain a temperature set point.) <br />M&V Measurement and verification; the.process of determining savings using one <br />of the four IPMVP options. <br />MCF An industry standard measure of a gaseous fuel, typically natural gas, <br />having volume of 1,000 cubic feet. (See also, Decatherm) <br />Operational Cost Avoidance Often referred to as O&M cost avoidance, this includes the avoided costs of <br />operating and maintaining the facilities, such as, but not limited to, the avoided cost <br />of inside and outside labor to repair and maintain affected systems and equipment, <br />the avoided cost of custodial supplies, the avoided cost of replacement parts, the <br />avoided cost of deferred maintenance, the avoided cost of lamp and ballast <br />disposal, and the avoided cost of new capital equipment. <br />Plug Load Electrical energy -consuming equipment that draws its operating power <br />through cords and wall plugs. (i.e. Office equipment, refrigerators, freezers, <br />vending equipment, radios, TVs, microwave ovens, coffee pots, fans, floor heaters, <br />etc.) <br />Post -Retrofit Period Any period of time following commissioning of the ECMs. <br />Reference Year A period of time (usually one year) which defines the baseline usage and is <br />representative of the facility's operations, consumption, and usage that is used as <br />the benchmark for determining cost avoidance. This is also referred to as the "Base <br />Year" <br />Therm The energy content of a 100 cubic feet volume of a gaseous fuel; sometimes <br />used as a synonymous term for CCF. Technically, however, a therm is the Btu heat <br />content of 100 cubic feet of a gaseous fuel, where the Btu content varies based on <br />source and quality. <br />5.3 <br />
