MEPS (Minimum Energy Performance Standard) is a specification containing a number of performance requirements for an energy-using device, and that effectively limits the maximum amount of energy that may be consumed by a product in performing a specified task. A MEPS is usually made mandatory by a government 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. Unless you are in the UK. A MEPS 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"). ==Examples== * A refrigerating appliance is required to maintain temperatures inside its compartments within specified limits, and to operate (including defrosting) in a specified ambient temperature while using at most a specified amount of electricity; the energy use allowed varies according to volume, number of doors, the function of the various compartments and other parameters. This graph shows the dramatic reduction in electricity use in U.S. refrigerators following the introduction of a series of first California then U.S. MEPS starting in the mid-1970s: * An electric fan is required to shift air at a specified rate while consuming a limited amount of power. A storage water heater providing hot water for sanitary purposes is required to heat up a specified quantity of water to a specified temperature and store it at that temperature for a specified time while consuming a limited amount of energy. In this example, the requirements for heating up and for maintaining the temperature may be applied as two separate energy performance requirements or there may be a single task efficiency. * An electric induction motor is required to have a specified minimum full-load efficiency. A compact fluorescent lamp is required to start and run up to near full brightness in a given time, to have a minimum life of several thousand hours, to maintain its output within specified limits, to withstand a certain number of switchings, to have a consistent colour appearance and a specified colour rendering. Its energy performance requirement is usually stated in terms of minimum efficacy (light output per electrical input). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Minimum energy performance standard」の詳細全文を読む スポンサード リンク
