Energy Star was introduced by EPA in 1992 as a market-based partnership to reduce greenhouse gas emissions through energy-efficiency. Energy Star offers businesses and consumers energy-efficient solutions to decrease energy consumption, save money, and help protect the environment. More than 20,000 organizations are Energy Star partners, committed to improving energy-efficiency in homes, products, and businesses.
To earn the ENERGY STAR, a home must meet strict guidelines for energy efficiency set by the U.S. Environmental Protection Agency. These homes are at least 15% more energy efficient than homes built to the 2004 International Residential Code (IRC), and include additional energy-saving features that typically make them 20–30% more efficient than standard homes.
