Energy Star
Product range:
Energy Star is a government program jointly implemented by the U.S. Department of Energy and the U.S. Environmental Protection Agency to better protect the living environment and save energy. In 1992, it was participated by the US Environmental Protection Agency and was first promoted in computer products. Now the products included in the scope of this certification have reached more than 30 categories, such as household appliances, heating/cooling equipment, electronic products, lighting products, etc., and the most done in the Chinese market is lighting products, including energy-saving lamps (CFL), lamps (RLF), traffic lights and exit indicators.
What is Energy Star?
Energy Star is a U.S. government-led energy conservation program focused on consumer electronics. The ENERGY STAR program was launched in 1992 by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE) to reduce energy consumption and greenhouse gas emissions. The plan was later adopted by Australia, Canada, Japan, Taiwan, New Zealand and the European Union. The program is voluntary, and the ENERGY STAR standard typically consumes 20-30% more energy than the U.S. federal standard. The earliest products to cooperate with this plan were mainly information appliances such as computers, and then gradually extended to motors, office equipment, lighting, home appliances and so on. Since 1996, the EPA has actively promoted the ENERGY STAR Building Program, in which EPA assists voluntary participants in assessing the energy use of their buildings (including lighting, air conditioning, office equipment, etc.), planning an energy efficiency improvement action plan for the building, and tracking operations, so that the Energy Star logo can also be found in some homes or commercial buildings that introduce new environmental concepts.

At present, the products for which we are: fluorescent lamps, decorative strings, LED lamps, power adapters, switching power supplies, ceiling fan lights, consumer audio-visual products, battery charging equipment, printers, household appliances and other types of products.
Launch status
A total of seven countries and regions around the world have participated in the ENERGY STAR program promoted by the EPA, namely the United States, Canada, Japan, Taiwan, Australia, New Zealand, and the European Union, and the International Energy Star Program Conference has been held annually since 2001. Now the products included in the scope of this certification have reached more than 30 categories, such as household appliances, heating/cooling equipment, electronic products, lighting products, etc., and the most done in the Chinese market is lighting products, including energy-saving lamps (CFL), lamps (RLF), traffic lights and exit indicators.
On April 2010, 4, the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE) jointly announced adjustments to the certification process for ENERGY STAR products to ensure that only products that meet the requirements are approved for the ENERGY STAR label. In this adjustment, effective immediately, manufacturers must submit a complete test report and evaluation results in order to obtain the ENERGY STAR certification label, and be certified by EPA that manufacturers will not be able to obtain the ENERGY STAR certification mark until EPA reviews and approves the product as an ENERGY STAR qualified product. At the same time, during the ENERGY STAR qualification review process, EPA enhanced its approval system, moving away from relying on an automated approval process and instead inspecting and approving all new applications for qualification.
EPA and DOE further strengthened ENERGY STAR's certification process by the end of 2010, requiring all manufacturers to submit test results from accredited, approved laboratories to ensure that their products meet ENERGY STAR requirements. The products currently involved include windows, doors, skylights and fluorescent bulbs, and in the new testing process, the product categories under the ENERGY STAR program will be expanded to more than 60, including freezers, refrigerated freezers, washing machines, dishwashers, water heaters and room air conditioners.
Energy Star Residential Program
The EPA's ENERGY STAR Housing Program is a nationwide volunteer program to build a new type of home that is 30 percent more energy efficient. Qualified ENERGY STAR residences are subject to third-party verification to confirm that the builder has appropriately adopted measures to improve energy efficiency. As long as the Energy Star logo can be seen, the purchaser of the home can make a purchase decision with confidence without being an expert. In general, ENERGY STAR homes use 30% more energy than homes built to common energy specifications, while protecting the environment and saving energy bills for residents. Energy Star residential construction benefits not only buyers, but also builders, mortgage companies, and other organizations in the housing industry, so homebuilders across the United States support the Energy Star Housing Program.
Residences are usually newly built dwellings because it is much simpler to build a home that meets energy efficiency rules than to renovate an existing home. Although upgrading a home to earn the Energy Star logo is expensive, it can significantly reduce energy bills, so it is still a good idea to retrofit existing homes. When replacing air conditioning, 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 the home Energy Star.
The Energy Star Residential Program uses the Residential Energy Evaluation System (HERS) to determine the energy efficiency score of a home. Both new and existing homes must meet the same energy efficiency standards to receive the ENERGY STAR logo. In order to be evaluated by HERS, or to seek a way to obtain the ENERGY STAR mark, it is also necessary to consult with the local qualified residential energy assessment agency to compare the model dwelling (which is the same size and shape as the assessed dwelling and meets the minimum requirements of the energy specification), and the HERS assessment system provides an objective, standard evaluation of the energy efficiency of the dwelling. The HERS assessment score ranges from 0 to 100. The score for model houses is 80 points. For every 5% reduction in energy consumption compared to model houses, it equals one point increase in HERS. Energy Star Residences has the lowest HERS assessment of 86. HERS' assessment includes on-site testing of homes. This test includes a hair dryer door test and a pipe leak test. The results of these tests, along with other information about the home, are fed into a simulated computer program to calculate the HERS score and estimate the annual energy bill.
Energy-saving window use
ENERGY STAR Residences are equipped with high-performance energy-saving windows to improve the energy efficiency of the residence. A quieter interior – multiple layers of glass and sealed window frames block out external noise; Prevents fading of curtains, furniture and floors – energy-efficient window surfaces are covered with a low-reflectivity coating that blocks 98% of UV rays; Reduce the cost of use - energy-efficient windows allow the house to reduce heat loss in winter and prevent heat absorption in summer; Improved quality – Energy-efficient windows are manufactured using high-quality materials, are easy to use, and provide additional assurance to the user. Windows occupy about 10-25% of the area of the exterior wall of the house, and depending on the climate in different places, it consumes 25-50% of the energy when heating and cooling the room. Therefore, when building a new home, it is crucial to consider the use of energy-efficient windows.
Heating and cooling equipment
Energy Star residences are equipped with appropriately powered, efficient heating and cooling equipment. During the construction of a home, heating and cooling equipment in an Energy Star residence is generally less powerful than a home built in accordance with common energy codes by paying due attention to the sealing of air ducts, the thermal insulation of the house, and the installation of energy-efficient windows.
Reduced cost of ownership – heating and cooling equipment does not need to be overloaded;
Reduced maintenance issues – heating and cooling equipment is always operating optimally;
A quieter home environment – no need to constantly and frequently turn ultra-powerful devices on and off.
Poor air and ventilation ducts mean that the heating and cooling equipment of ordinary homes needs to increase power to quickly meet its requirements for heat and cold. However, this high-power equipment has great drawbacks: (1) it cannot operate for a long time to achieve its most efficient operating level; (2) When the system cannot operate for a long time to remove moisture in the air, it leads to the problem of dampness in the house; (3) High-power equipment often causes the equipment to be paralyzed quickly due to frequent start-up. Tight air and ventilation ducts reduce the need for air conditioning gas heating and cooling in the home, thus avoiding the use of high-power equipment.
Improved thermal insulation performance
Energy Star homes offer a significant improvement in thermal insulation compared to those built according to common energy codes. The improvement of thermal insulation performance not only prevents excessive hot and cold spillage, but also maintains a constant temperature between rooms.
Increased comfort – maintaining a constant temperature throughout the home and between rooms.
Reduced cost of ownership – HAVC equipment compensates for a small amount of heat and cold exchange in the house in winter and summer.
In order to effectively maintain the temperature of the home, continuous insulation inside and outside is required. The insulation must be laid without cracks, curling or compression. Energy Star homes must also pay attention to insulation around obstacles such as pipes, wires, and exits.
Well sealed
Sealed Conduits Energy Star residences have much higher requirements for conduit tightness than homes built to common energy codes. Sealed conduits are essential to save energy and maintain the comfort of your home.
More sustained comfort – assign to each room.
Significantly improve indoor air quality – reducing dust and other pollutants drawn in by the room from the outside.
Reduced cost of ownership – reduced room need for air conditioning gas. In a typical American home, 20-30% of the air leaks through the ducts, which means that a lot of unnecessary money is spent to warm or cool the room. The duct system should remain sealed and tested locally to reduce air conditioning gas leakage.
Energy-saving retrofit
Owners of existing homes can use the Energy Star Housing Benchmark, an Internet-based assessment tool, to compare the annual energy consumption of similar homes in their country. This tool helps owners of existing homes understand whether their homes meet energy efficiency requirements and whether they should upgrade their home energy efficiency measures to improve energy efficiency. On the ENERGY STAR website, this tool also helps owners of existing homes quickly decide which home retrofit to choose to improve energy efficiency.
The ENERGY STAR Residential Program also offers a "Home Retrofit Kit" to help existing homes undergo energy-efficient retrofits. The average household spends 1400 per year on energy use with the help of the "Housing Renovation Kit" can reduce these expenses by 30%, and almost 400% When repairing, rebuilding or improving existing homes, the energy-saving measures in the "Housing Renovation Toolbox" can help homeowners improve the energy efficiency, use value and comfort of their homes, and protect the ecological environment by reducing energy consumption. For homeowners, the Home Retrofit Toolbox makes home renovation and renovation projects easier.
