EnerGuide rating to indicate the energy performance of a dwelling

The EnerGuide rating is used to reflect a dwelling's energy performance. It is a standardized measurement system across Canada.

As part of the Rénoclimat program, a home's EnerGuide rating is determined based on the blower door test and information collected by the Rénoclimat advisor during their visit to your home.

With this data, each advisor can use the energy performance evaluation system for homes managed by Natural Resources Canada to establish a home's EnerGuide rating.  

The EnerGuide rating appears:

• in the Rénoclimat evaluation report;
• on the EnerGuide label;
• in the homeowner information sheet.

The EnerGuide rating is an estimate of the net amount of energy a home consumes in a year. The lower the rating value, the better the home's energy performance.

The EnerGuide rating is expressed in gigajoules per year (GJ/year).

The EnerGuide rating considers not only energy consumption but also renewable energy production, if applicable. The optimal EnerGuide rating is zero, which occurs when a home produces as much energy as it consumes.

Track the evolution of your home’s EnerGuide rating

You can track the evolution of your home's EnerGuide rating with each Rénoclimat energy evaluation. Energy efficiency retrofits generally result in a decrease in a home's EnerGuide rating.

You can compare your home's EnerGuide rating to that of a new home of similar size. Ideally, your energy efficiency retrofits should allow you to approach or surpass this reference value.

The work you carry out must improve the energy performance of your home to make you eligible for Rénoclimat financial assistance.

The EnerGuide rating system is a standardized tool for evaluating the energy performance of homes across Canada, managed by Natural Resources Canada.

This system is used to define best practices for energy efficiency construction and renovation.

Learn more about the EnerGuide rating system by visiting the Natural Resources Canada website.

Until 2019, the EnerGuide rating ranged from 0 to 100 and served as an indicator of a home's energy efficiency.

Homeowners who received a Rénoclimat energy evaluation before October 1, 2019, are registered under the previous EnerGuide rating system. However, the GJ/year rating will be used for their post-retrofit or subsequent evaluations.
