Which Version of the Program Requirements Should I Use?

The ENERGY STAR Certified Homes program helps homebuyers easily identify homes that are significantly more energy efficient than standard construction in the marketplace. As code requirements have become more rigorous and builder practices have become more efficient, EPA has periodically modified the guidelines to ensure that certified homes represent a meaningful improvement over non-labeled homes.

To earn the ENERGY STAR, a home must be certified under Version 3 of the program requirements, unless it is located in California, Florida, Guam, Hawaii, Illinois, Maryland, Massachusetts, Oregon, Puerto Rico, Rhode Island, or Washington. A home in these locations must be certified using Regional Specifications.

EPA has developed an alternative set of guidelines for manufactured homes built to the HUD code and multifamily high rise buildings.
