ENERGY STAR® is a joint program of the Environmental Protection Agency (EPA) and the Department of Energy (DOE). Its goal is to help consumers, businesses, and industry save money and protect the environment through the adoption of energy efficient products and practices. The ENERGY STAR label identifies top performing, cost-effective products, homes, and buildings.
Since inception, ENERGY STAR has shown impressive results: in 2010 Americans saved enough energy to avoid greenhouse gas emissions equivalent to those from 33 million cars, while saving nearly $18 billion on utility bills.
A Memorandum of Understanding between EPA and DOE on improving the energy efficiency of products and buildings establishes working arrangements to enhance and expand the various aspects of ENERGY STAR. EPA and DOE are coordinating efforts to expand and enhance the ENERGY STAR products program, the Home Performance with ENERGY STAR program, and the National Building Rating Program, also known as the Commercial Building Energy Asset Score program.
- The ENERGY STAR products program sets specifications, testing procedures, and verification testing requirements for various consumer appliances, electronics, and commercial equipment.
- The Home Performance with ENERGY STAR program combines DOE's research into residential energy use with ENERGY STAR's outreach capabilities to promote energy-efficient home retrofits.
- The Commercial Building Energy Asset Score program is developing a commercial building energy asset rating program to allow building owners, managers, and operators to more accurately assess building energy performance.
ENERGY STAR Most Efficient Program
The ENERGY STAR Most Efficient program was launched in May of 2011 by DOE and EPA to identify and advance highly efficient products in the marketplace. Its goal is to increase market awareness and promote innovation in these products. This program identifies the most efficient products among those that qualify for ENERGY STAR for certain product categories on an annual basis. Additional information about the ENERGY STAR Most Efficient Program can be found on the EPA website.
