Minimum energy performance standard
From Wikipedia, the free encyclopedia
MEPS (Minimum Energy Performance Standard) — 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.
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").

[edit] 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).
[edit] California
In the U.S. the state of California was a pioneer [1] in the introduction of MEPS. The California Energy Commission was created in 1975 in response to the oil crisis as well as the rapid growth in electricity demand in the early 1970s. It order to reduce the grow in electricity use it was given unique and strong authority to regulate the efficiency of appliances sold in the state. It started to adopt appliance efficiency regulations in 1978, and has updated the standards regularly over time, and expanded the list of covered appliances.
In 1988, California's standards became national standards for the U.S. through the enactment of the National Appliance Energy Conservation Act (NAECA). The federal standards preempted state standards (unless the state justified a waiver from federal preemption based on conditions in the state), and since then, the U.S. Department of Energy has had the responsibility to update the federal standards.
California has continued to expand the list of appliances it regulates for appliances that are not federally-regulated, and therefore not preempted. In recent years the CEC's attention has been focused on consumer electronics, for which energy use has been growing dramatically.
[edit] Australia
MEPS programs are made mandatory in Australia by state government legislation and regulations which give force to the relevant Australian Standards. It is mandatory for the following products manufactured in or imported into Australia to meet the MEPS levels specified by the relevant Australian Standards:
| Appliance | Date |
|---|---|
| Refridgerators and freezers | 1 October 1999 |
| Mains pressure electric storage water heaters | 1 October 1999 |
| Three phase electric motors | 1 October 2001
|
| Three phase air conditioners | 1 October 2001 |
| ballasts for linear fluorescent lamps | 1 March 2003 |
| Single phase air conditioners | 1 October 2004 |
| Linear fluorescent lamps | 1 October 2004 |
| Distribution transformers | 1 October 2004 |
| commercial refridgeration | 1 October 2004 |
| Pressure electric storage water heaters smaller than 80 liters, low pressure and heat exchange types |
1 October 2005 |
[edit] Brazil
A law was approbed in 2001[3]. MEPS have been set for three-phase electric motors and compact fluorescent lamps.
[edit] New Zealand
On 5 February 2002, the Energy Efficiency Regulations introduced Minimum Energy Performance Standards (MEPS) to New Zealand.
MEPS became mandatory from 1 July 2002 for domestic refrigerators and freezers, three-phase cage induction motors, fluorescent tubes, and packaged air conditioning units. MEPS for domestic electric storage water heaters and ballasts took effect from 1 February 2003. MEPS for distribution transformers, refrigerated display cabinets, and household air conditioners became effective on 1 October 2004[4].
New Zealand works with Australia to keep MEPS levels the same. Almost all of its standards are joint standards with Australia.
New Zealand has mandatory MEPS for the following[5]:
- Fridges and freezers
- Electric hot water cylinders
- Air conditioners
- Three-phase electric motors
- Refrigerated display cabinets
- Fluorescent lamps
- Ballasts for fluorescent lamps
- Distribution transformers
