Energy Star is a government-backed labeling program that helps people and organizations save money and reduce greenhouse gas emissions by identifying factories, office equipment, home appliances and electronics that have superior energy efficiency. In recent years,
Energy Star originated in 1992 as a joint program of the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DoE). In 2007, the European Union adapted Energy Star, including related standards, for all of its members. Australia and New Zealand has already adopted the program. As a result, the Energy Star symbol has become the international symbol for energy efficiency.
Energy Star ratings have been extended to some new homes, commercial and industrial facilities.
Any building or product that has received an Energy Star rating carries a blue logo. Energy Star is a voluntary labeling system, though most manufacturers find it commercially desirable to display the logo if their products qualify. The standards themselves, however, are set by governmental agencies.
Energy Star labels, for instance, are only awarded to homes that have been independently verified to be at least 15% more efficient than the standard mandated by the relevant state or local energy codes in a given area.
