Minimum energy performance standard

A minimum energy performance standard (MEPS) is a specification, containing a number of performance requirements for an energy-using device, that effectively limits the maximum amount of energy that may be consumed by a product in performing a specified task.

An MEPS is usually made mandatory by a government's energy efficiency body. It may include requirements not directly related to energy; this is to ensure that general performance and user satisfaction are not adversely affected by increasing energy efficiency. It generally requires use of a particular test procedure that specifies how performance is measured.

In North America when addressing energy efficiency, a MEPS is sometimes referred to simply as a "standard", as in "Co-operation on Labeling and Standards Programs". In Latin America when addressing energy efficiency, MEPS are sometimes referred to as Normas (translated as "norms").
