values obtained by window and door manufacturers through the National Fenestration Rating Council (NFRC) program. NFRC ratings are based on the energy performance of the total window or door – both glass and frame. The Energy Star program for the United States divides the nation into four separate climate zones – Northern, North-Central, South-Central, and Southern. The performance criteria that needs to be met in order to be Energy Star compliant in a specific climate zone (effective January 1, 2015) is shown in the charts provided.
2016 ENERGY STAR Qualification Criteria for Windows The effective date for the Northern Zone prescriptive and equivalent energy performance criteria for windows is January 1, 2016. North-Central, South- Central, and Southern criteria will continue to follow 2015 guidelines.
