EPA Clarifies References to ENERGY STAR Windows Guidelines

More stringent specifications for ENERGY STAR qualified windows went into effect on January 1, 2010. For more information, on the new ENERGY STAR Windows, Doors, and Skylights requirements, visit www.energystar.gov/windows.

Due to the upcoming new guidelines for ENERGY STAR certified homes that will become effective next year, EPA has decided not to update the current ENERGY STAR for Homes guidelines for windows at this time and will allow homes to continue to be qualified using the previous ENERGY STAR window specifications. However, the new ENERGY STAR window specifications will be integrated into the upcoming ENERGY STAR for Homes Version 3 guidelines that will become mandatory in January, 2011.

EPA has posted revised guidelines highlighting this policy clarification, which are available through the "Technical Resources" link on www.energystar.gov/homes
