Introduction to certification
Energy star is an energy saving program led by the U.S. government, mainly aimed at consumer electronics. Energy star was launched in 1992 by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of energy (DOE) was launched to reduce energy consumption and greenhouse gas emissions. The program was later adopted by Australia, Canada, Japan, Taiwan, New Zealand and the European Union. The program is voluntary. The energy star standard usually saves energy by 20-30% compared with the federal standard of the United States. The first products to cooperate with the program are computers and other information appliances, and then gradually extended to electrical machines Since 1996, EPA has been actively promoting the Energy Star building program. The EPA has assisted voluntary participants in assessing the energy use of their buildings (including lighting, air conditioning, office equipment, etc.) Plan the energy efficiency improvement action plan of the building and follow-up follow-up work. Therefore, the sign of energy star can be found in some houses or industrial and commercial buildings with new concept of environmental protection.
Development status
Seven countries and regions around the world have participated in the Energy Star program promoted by the US Environmental Protection Agency, namely the United States, Canada, Japan, Taiwan, Australia, New Zealand and the European Union. Since 2001, the International Energy Star Program conference has been held annually. At present, more than 30 kinds of products have been included in the scope of certification, such as household appliances, heating / cooling equipment, electronic products, lighting products, etc. at present, the lighting products, including energy-saving lamps (CFL), lamps (RLF), traffic signal lights and export lights, are the most popular products in the Chinese market.

Energy star housing project
The EPA's energy star housing program is a national voluntary program designed to build a new type of home with an energy efficiency increase of 30%. A qualified Energy Star house must be verified by a third party to confirm that the builder has properly adopted measures to improve energy efficiency. As long as you can see the energy star logo, the home buyer is not an expert and can make a purchase decision with confidence. In general, energy star houses save 30% less energy than those built to general energy codes, while protecting the environment and saving energy costs for households. The construction of energy star housing is beneficial not only to buyers, but also to builders, mortgage companies and other organizations in the housing industry. Therefore, housing builders in the United States support the energy star housing program.
Houses are usually newly built because it is much easier to build a house that meets energy conservation rules than to renovate an existing one. Although it costs a lot to upgrade the residential buildings to obtain the energy star logo, it can greatly reduce the energy consumption expenditure. Therefore, it is still a good suggestion to carry out energy-saving transformation for the built houses. When replacing air-conditioning equipment, electrical equipment or lighting equipment, you should also consider purchasing products with the energy star logo, which can further improve the energy-saving effect of residential buildings.
Energy star housing plans to use the residential energy assessment system (HERS) to determine the energy efficiency score of a home. New and built residential buildings must meet the same energy-saving standards to obtain the energy star logo. In order to get the evaluation of her, or to seek the way to obtain the energy star logo, it is also necessary to consult the local qualified residential energy assessment agency to compare the model house (it has the same size and shape as the house to be evaluated, and meets the minimum requirements of the energy code). The energy efficiency of the house is evaluated objectively and standard by the hes evaluation system. Her scores ranged from 0 to 100. The score of model house is 80. Compared with the model house, every 5% reduction in energy consumption is equivalent to an increase in her by one point. The lowest her rating for energy star housing is 86. Her assessment includes on-site inspection of the residence. This test includes blower door test and pipeline leakage test. The results of these tests, together with other information about the house, are fed into a simulated computer program to calculate her scores and estimate the annual energy cost.
Use of energy saving windows Energy star housing is equipped with high-performance energy-saving windows to improve energy efficiency. Quieter indoor environment: multi layer glass and sealed window frame block external noise; Prevent discoloration of curtains, furniture and floors - energy saving windows are covered with low reflectivity coating, which can block 98% of UV light; Reduce the cost of use - energy saving windows reduce heat loss in winter and prevent heat absorption in summer; Quality improvement - energy saving windows are made of high quality materials, easy to use and provide additional protection for users. Windows take up about 10-25% of the external wall area of the house. According to the different climate conditions in different regions, it needs to consume 25-50% energy when heating and cooling the room. Therefore, when building a new house, it is very important to consider the use of energy-saving windows.
Heating and cooling equipment Energy Star houses are equipped with appropriate power and efficient heating and cooling equipment. In the process of residential construction, the power of heating and cooling equipment in Energy Star residential buildings is usually less than that in residential buildings built according to general energy specifications by paying proper attention to the sealing of air pipes, thermal insulation performance of residential buildings and installation of energy-saving windows. Reduce operating costs - heating and cooling equipment does not need to work overload; Reduce maintenance problems - heating and cooling equipment is always operating under optimal conditions; Quieter home environment - no need to constantly and frequently switch on and off super power devices. The air and ventilation pipes are not tight, which means that the heating and cooling equipment of ordinary residence need to increase the power to meet the requirements of cooling and heating quickly. However, this kind of high-power equipment has many disadvantages: ① it can not operate for a long time to reach its most efficient operation level; ② When the system can not operate for a long time to remove the moisture in the air, it will lead to the problem of humidity in the house; ③ High power equipment is often broken down because of frequent start-up. Tight air and ventilation ducts reduce the demand for air-conditioning gas heating and cooling in residential buildings, thus avoiding the use of high-power equipment.
Improvement of thermal insulation performance Compared with those built according to the general energy code, the insulation performance of Energy Star house is greatly improved. The improvement of heat insulation performance not only prevents excessive cold and hot overflow, but also maintains a constant temperature between rooms. Increased comfort - maintaining constant temperature throughout the house and between rooms. Reduce operating costs - HAVC equipment compensates for a small amount of heat and cold exchange in winter and summer. In order to effectively maintain the temperature of the house, continuous thermal insulation layer is necessary. Insulation must be laid without cracks, curls or compression. Energy Star residences must also pay attention to thermal insulation around obstacles such as pipes, wires and exits.
Seal well Compared with residential buildings built in accordance with the general energy code, energy star houses have much higher requirements for duct tightness. Sealed conduit is essential for energy conservation and comfort. More continuous comfort - assign to each room Significantly improve indoor air quality - reduce the amount of dust and other pollutants that the room inhales from the outside world. Reduce the cost of use - reduce the need for air conditioning gas in the room. In a typical American home, up to 20-30% of the air is leaking out of the duct, which means a lot of unnecessary money is spent to make the room warm or cool. The duct system should be sealed and tested locally to reduce air-conditioning gas leakage.
Energy saving transformation The owners of built houses can compare the annual energy consumption of similar houses in their country by using the energy star housing benchmark, an assessment tool based on the international Internet. This tool helps owners of completed homes understand whether their homes meet energy-saving requirements and whether they should upgrade residential energy-saving measures to improve energy efficiency. On the energy star website, the tool can also help owners of completed homes quickly decide which way to choose to upgrade their homes to improve energy efficiency.
The energy star housing program also provides a "residential retrofit toolbox" to help existing homes carry out energy-saving retrofits. The average household's annual energy expenditure is 1400. The help of the "housing transformation toolbox" can reduce these expenditures by 30%. When repairing, rebuilding or improving the built houses, the energy-saving measures in the "residential transformation toolbox" can help the housing owners improve the energy efficiency, use value and comfort of their houses, And the ecological environment is protected by reducing energy consumption. For the owner of the house, "residential renovation toolbox" makes it easier to rebuild and repair the house.
