key terms
| Question | Answer |
|---|---|
| British Thermal Unit (Btu) | amount of heat required to raise the temperature of one pound of liquid water from 60° to 61° F. This standard measure of energy is used to describe the energy content of fuels and compare energy use. |
| Building Envelope | exterior surface of a building --- the walls, windows, roof, & floor; also referred to as the building shell. |
| Chiller | device that removes heat from a liquid typically as part of a refrigeration system used to cool & dehumidify buildings. |
| Compact Fluorescent Lamp (CFL) | small fluorescent lamp, used as a more efficient alternative to incandescent lighting; also called a PL, twin-tube, or biax lamp. (EPA) |
| Energy-Efficient Products and Systems | building components and appliances that use less energy to perform as well as or better than standard products. |
| Energy or Greenhouse Gas Emissions per Capita | a community’s total greenhouse gas emissions divided by the total number of residents. |
| Energy Management System | control system capable of monitoring environmental & system loads and adjusting the HVAC operations accordingly in order to conserve energy while maintaining comfort. (EPA) |
| ENERGY STAR Rating | measure of a building’s energy performance compared with that of similar buildings. A score of 50 represents average building performance. |
| Energy Use Intensity | energy consumption divided by the number of square feet in a building, often expressing as British thermal units (Btus) per square foot or as kilowatt-hours of electricity per square foot per year (kWh/sf/yr). |
| Fossil Fuel | energy derived from ancient organic remains, such as peat, coal, crude oil, and natural gas. (EPA) |
| HVAC systems | equipment, distribution systems, and terminals that provide the processes of heating, ventilating, or air-conditioning. (ASHRAE Standard 90.1 – 2007) |
| Lighting Power Density | the installed lighting power per unit area. |
| Measures of Energy Use | typical primary measures of energy consumption associated with buildings include kilowatt-hours of electricity, therms of natural gas, & gallons of liquid fuel. |
| Nonrenewable | not capable of being replaced; permanently depleted once used. Examples of nonrenewable energy sources are oil and natural gas; nonrenewable natural resources include metallic ores. |
| Performance Relative to Benchmark | a comparison of a building system’s performance with a standard, such as ENERGY STAR portfolio manager. |
| Performance Relative to Code | comparison of a building system’s performance with a baseline that is equivalent to minimal compliance with an applicable energy code, such as ASHRAE Standard 90 or California’s Title 24. |
| Photovoltaic (PV) Energy | electricity from photovoltaic cells that convert the energy in sunlight into electricity. |
| Renewable Energy | resources that are not depleted by use. Examples include energy from sun, wind and low-impact hydropower, geothermal energy, and wave/tidal systems. |
| Renewable Energy Certificate (REC) | a tradable commodity representing proof that a unit of electricity was generated from a renewable energy resources; typically sold separately from the electricity and allows the purchase of green power by a user of conventionally generated electricity. |
