To determine if your windows are ENERGY STAR® certified, look for the official blue ENERGY STAR logo on a temporary sticker attached to the glass or a permanent label on the window frame/sash, typically near the hardware. This label also contains the National Fenestration Rating Council (NFRC) rating.
If purchasing a window, door, or skylight off the shelf, look for the ENERGY STAR label for your climate zone next to the NFRC label on the glass.
A window product's rating is listed at the top of the label using a letter and associated colour band. This rating can be used to compare several window products on the basis of energy efficiency. A++ is the most energy-efficient.
When purchasing ENERGY STAR qualified windows, look for the U-Factor and the Solar Heat Gain Coefficient (SGHC). The U-Factor measures how well the window in- sulates. While the U-Factor can take any value, in general for windows it ranges from 0.20 to 1.20. The lower the U-Factor, the better the window insulates.
Installing alternative energy equipment in your home such as solar panels, heat pumps, windows, doors and roofing can qualify you for a credit up to 30% of your total cost. See the details below for details on the programs available to help you go green while saving on your taxes.
