There are many ENERGY STAR qualified window, door, and skylight models available, however ENERGY STAR does not maintain a list because qualification is dependent on geographic usage for windows and skylights, and on glazing level for doors. A particular window or skylight may be qualified in Florida, but not Colorado. A door may or may not qualify depending on the amount of glass installed and, as with windows and skylights, the type of glass package used. Please contact the manufacturer directly to determine if a particular model is ENERGY STAR qualified and check the U-Factor and SHGC to confirm (see page 5).
