Energy Star (trademarked ENERGY STAR) is an energy-efficiency program administered by the U.S. Environmental Protection Agency (EPA) in partnership with the U.S. Department of Energy (DOE). [ 2 ] [ 3 ] [ 4 ] The EPA establishes energy efficiency specifications, and those that meet these specifications are eligible to display the ENERGY STAR logo.
A new energy label, introduced in 2010, is based on the energy efficiency index (EEI), and has energy classes in the range A+++ to D. [11] The EEI is a measure of the annual electricity consumption, and includes energy consumed during power-off and standby modes, and the energy consumed in 220 washing cycles. For the washing cycles, a weighted ...
The House Energy Rating (HER) or House Energy Rating Scheme (HERS) are worldwide standard measures of comparison by which one can evaluate the energy efficiency of a new or an existing building. The comparison is generally done for energy requirements for heating and cooling of indoor space. The energy is the main criterion considered by any ...
Appliances and equipment that qualify to carry the energy star mark are generally in the top 25% most energy efficient products. In Australia, the label is used for office equipment and home electronics. New Zealand uses the energy star label for a much wider range of products such as whitegoods, lighting, heating, water heating and windows. [1]
Energy Star is a similar labeling program, but requires more stringent efficiency standards for an appliance to become qualified, and is not a required program, but rather a voluntary one. See also [ edit ]
