Energy Star Climate Zones

Canada is divided into four climate zones based on annual average temperature. Zone A is the mildest, and Zone D is the coldest.

Make sure that the product model you are buying is qualified for the correct climate zone, or, to save even more energy, for colder zones.

Key Features:

An ENERGY STAR qualified window, door or skylight will have many of the following features:

  • double- or triple-glazing, with a sealed insulating glass unit
  • low-e glass
  • inert gas, such as argon or krypton, in the sealed unit
  • low-conductivity or ‘warm edge’ spacer bars
  • insulated frames, sashes and door cores

The ENERGY STAR name and symbol is administered and promoted in Canada by Natural Resources Canada and is registered in Canada by the United States Environmental Protection Agency.
