Glossary of Terms <br />Actual Cost Actual energy cost taken directly from utility bill. <br />Adjustment Calculations used to bring energy usage in base year to the same set of conditions <br />as the current year. <br />Balance Point Temperature (BPT) For heating degree-days, the outdoor temperature below which space heating is <br />required; for cooling degree-days, the outdoor temperature above which space <br />cooling is required. This is typically 65 degrees, but varies based on building type, <br />construction material, etc. <br />Baseline The raw base year data adjusted by the energy impact of the variables between the <br />years being compared. <br />BTU British thermal unit; the quantity of heat required to raise the temperature of one <br />pound of water by one degree Fahrenheit. <br />BTUh The quantity of heat generated/consumed over a one hour period. <br />CDD Cooling Degree -Day; a value that represents weather condition severity. It is the <br />monthly sum of the daily mean temperature (measured by the National Weather <br />Service) above the cooling Balance Point. <br />Cost Avoidance The difference between the actual cost incurred during a selected time period <br />versus what the cost would have been had the cost avoidance strategy not been <br />implemented. <br />ECM The Energy Conservation Measure (ECM) is the installation of equipment or <br />systems, or modification of equipment or systems, for the purpose of reducing <br />utility (energy, water, etc.) consumption, demand and costs and/or non -utility <br />(O&M, operational) costs. <br />EMS Energy Management System; a computer that can be programmed to control and/or <br />monitor the operations of energy -consuming equipment in a facility. <br />Guarantee Period The period beginning on the first (Ist) day of the First Guarantee Year and ending <br />on the last day of the final Guarantee Year. Also known as the "Measurement and <br />Verification Phase" or "Performance Period". <br />Guarantee Year The First Guarantee Year and each of the successive twelve (12) month periods <br />commencing on the anniversary of the commencement of the First Guarantee Year <br />throughout the tern of the agreement. <br />Guaranteed Savings The amount of avoided Energy and Operational Costs necessary to pay for the cost <br />of the Work and Support Services incurred by the customer in each Guarantee <br />Year. <br />HDD Heating Degree -Day; a value that represents weather condition severity. It is the <br />monthly sum of the daily mean temperature (measured by the National Weather <br />Service) below the heating Balance Point. <br />5.2 <br />
