EnerGuide-rated new homes

Why choose an EnerGuide-rated new home?

  • Investments you make in energy efficiency at the construction stage will pay off in lower energy bills.
  • An EnerGuide rating, label and report will help you better understand your home’s energy performance, which may help you lower your energy use.
  • An EnerGuide label is an official record of your home’s energy performance, and may help increase its resale value.
  • EnerGuide is backed by the Government of Canada, and all participating builders must be registered with Natural Resources Canada.
  • Become part of the solution for reducing greenhouse gas emissions and addressing climate change.

Choose a builder who uses the EnerGuide Rating System to improve the energy performance of their homes.

Talk to your builder about the energy performance of your home and ask for an EnerGuide rating.

The EnerGuide Rating System has been updated

Natural Resources Canada updated the EnerGuide Rating System for homes to give homeowners more information about the energy performance of their homes. The new EnerGuide rating system demonstrates a home’s energy performance, rather than its energy efficiency.

During the transition, provinces and territories will keep using the 0-100 system until they are ready to adopt the new gigajoules per year system.

Which system is being used in your region?

New homes in Yukon, North West Territories, Alberta, Manitoba, Ontario British Columbia, Saskatchewan, Prince Edward Island, Nunavut, New Brunswick, Nova Scotia, Newfoundland and Labrador, have already switched to the new EnerGuide gigajoules rating system. (The 0-100 rating system may continue to be in use as well, due to existing incentive programs.)

New homes in Quebec are using the previous EnerGuide 0-100 system.

How the EnerGuide 0-100 scale works


In the 0-100 rating scale, the more efficient a house, the higher the rating number:

  • 0 represents a house that leaks a lot of air, has no insulation and uses a lot of energy. In other words, a house with poor energy efficiency and high utility costs.
  • 100 represents an airtight and well-insulated house where the energy it uses and the energy it generates through renewable sources (such as solar panels or geothermal) are equal. They are also called net zero energy homes.

EnerGuide Rating: Gigajoules per Year Scale


The EnerGuide gigajoules rating shows the energy performance of a home:

  • The lower the number, the better the energy performance of the home.
  • Zero (0) is the best energy performance a home can get. It indicates a home that produces as much energy as it consumes.
