How are windows rated for energy performance?
All ENERGY STAR qualifying windows, doors, and skylights also bear a label from the National Fenestration Rating Council (NFRC). NFRC provides unbiased energy performance ratings. Independent NFRC ratings provide the basis for the ENERGY STAR window performance requirements. NFRC's labels provide product-specific performance ratings for technical qualities such as U-factor (the rate of heat loss from your home through the window), and the Solar Heat Gain Coefficient (how much heat your house gains from the sun as a result of the window's performance).
