AlabamaWISE participants can be ensured of improved energy performance within their homes. The ENERGY STAR program for buildings and plants is a national program run by the EPA, which benchmarks a building’s energy performance against average building consumption. In LEED v4.1, the minimum energy performance requirement has changed to a minimum energy performance score that is calculated based on two factors: greenhouse gas emissions and source energy. One year ago, EPA updated the performance metrics and model used to determine Office building Energy Star scores. LEDs save on energy costs and last up to 20 years; CFLs also use less energy and last up to nine years. STAR Program. The NFRC label provides a reliable way to determine a window's energy properties and to compare products. The Energy Star score essentially rates a building on a curve, where “0” is the worst grade and “100” is the best. The NFRC label can be found on all ENERGY STAR® qualified window, door, and skylight products, but ENERGY STAR bases its qualification only on U-factor and solar heat gain coefficient ratings, which are described below.
