The EnerGuide rating demonstrates the energy performance of a home.

Aim towards zero on the rating scale. The lower the number, the better energy performance of the home.

Best energy performance indicates high performing homes with a rating of zero gigajoules per year, meaning they produce as much energy as they consume. Generally, these homes would be highly energy-efficient.

An annual gigajoule rating (GJ/year) allows you to see your score as a unit of energy consumption, similar to how you would see a consumption rating of kilowatts per hour for appliances, litres per 100 kilometres for vehicles, or calories for food.
