Details: EnerGuide Rating System v15

Re-post from Natural Resources Canada 

 

Why is the EnerGuide Rating System being updated?

Natural Resources Canada is in the process of updating the EnerGuide Rating System for homes in order to provide homeowners with increased access to customized information about the energy performance of their homes. This information can help with decision making when purchasing, operating or renovating a home.

The updates are being made to ensure our home energy performance rating tool reflects energy efficiency construction and renovation practices.  More than 300 key industry stakeholders were consulted as part of the update process, which was then open to a nationwide public review period.

During the consultation process, stakeholders from across Canada made it clear that the EnerGuide Rating System is being called upon to meet more needs and be more robust than ever before. For example, the rating system is now being used to support:

  • Development and implementation of regulations;
  • Design and implementation of utility, government and industry programs;
  • Design and evaluation of high performance and net zero energy homes.

 

Key Updates

Some of the main updates include:

  • Introduction of a new, consumption-based rating scale using gigajoules per year (GJ/year);
  • Redesigned informative house label;
  • New rating details report for homeowners;
  • New renovation recommendations report for homeowners;
  • Changes to elements included in the rating;
  • For the professionals who deliver the rating system: updated energy modelling software, house evaluation procedures and quality assurance procedures; and
  • Updated delivery network testing, licensing and registration.

New Label Design

EnerGuide label comparison

The updated EnerGuide label has brought many improvements including:

  • New EnerGuide rating scale gives you a consumption-based rating measured in gigajoules per year (GJ/year). The annual gigajoules per year rating allows you to see your score using units of energy similar to how you would see a consumption rating of kilowatt hours per year for home appliances, miles per gallon for vehicles, or calories per serving for food.
  • Your home’s EnerGuide rating calculation helps you understand your energy sources and the math that produced your home’s rating. The more intuitive rating scale makes it easier to understand the lower the number, the better energy performance of the home.
  • Unique and innovative label design is an energy performance snapshot of the more detailed information that you will find in the new Homeowner Information Sheet and allows you to see at a glance the largest energy uses in your home.
  • Your reference house, uniquely created for every home that’s rated, allows you to compare your rating to the rating your house would achieve if it were built to meet typical new home energy performance construction requirements.

 

FAQ

If I have an existing label can I update it to the new label? 

Ratings based on the 0-100 scale cannot be converted to the new gigajoules per year rating.  This is because the updated EnerGuide rating includes types of energy uses and some new calculations that were not previously included.  However, the recommendations you received under your existing label are still valid.

To obtain an updated EnerGuide rating and label, along with Homeowner Information Sheet, homeowners need to have a new EnerGuide home evaluation performed on their home, using the updated version of the rating system.

I just purchased a home that had an EnerGuide evaluation, can I get a copy of the Energuide rating report? 

The homeowner who purchased the EnerGuide rating services is the owner of the EnerGuide reports for the home and NRCan is bound by privacy laws to only share reports with the party that purchased them. However, homeowners are encouraged to share the reports with prospective homebuyers as part of the property selling transaction.
