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 specific climate zones are shown in the charts provided. Note that this information is per criteria that took effect in 2015 and 2016.

**Northern zone windows can meet prescriptive (1st row) or alternative energy performance (2nd, 3rd, and 4th rows) criteria to qualify for ENERGY STAR. *The effective date for the Northern Zone prescriptive and equivalent energy performance criteria for windows was January 1, 2016. North-Central, South- Central, and Southern criteria will continue to follow 2015 guidelines.
