Energy Star (Energy Star), is a dominated by the U.S. government, mainly for consumer electronics products, energy saving plans. The Energy Star Program in 1992 by the US Environmental Protection Agency (EPA) and the U.S. Department of energy (DOE) started, the purpose is to reduce energy consumption and reduce greenhouse gas emissions. The plan was Australia, Canada, Japan, Taiwan, New Zealand and the European Union adopted. The plan is voluntary, energy star standard is usually better than the federal standard for energy efficiency of 20-30%.'s early products of this program are computer information appliances, and then gradually extended to the motor, office equipment, lighting, household appliances and so on. Later expansion to the building, the United States Environmental Protection Agency in 1996 to actively promote energy star building plans by the environmental protection department to assist the voluntary participation of the industry is used to assess the status of the building energy (including lighting, air conditioning, office equipment Plan the building's energy efficiency improvement action plan and follow up operations, so some signs of the energy star can also be found in homes or industrial and commercial buildings introducing new concepts of environmental protection
