EnerGuide for Houses

Developed by Natural Resources Canada, the EnerGuide Rating System measures your home's energy efficiency and performance. Energy efficiency levels are rated based on a home's Gigajoules (GJ) of energy consumed per year, where the better the energy performance of a home is, the closer to zero it's rating will be.

Along with a home's EnerGuide rating, the label will also show a GJ rating of a house with similar characteristics; similar size, construction type, and location. You can use this typical house to compare your score with; for example, if a home's rating much higher than the average it indicates major home energy problems - serious air leakage, poorly performing insulation, and/or inefficient heating and cooling equipment. On the flip side, a rating much lower than average represents a home that is airtight, properly insulated, and with great energy efficiency.

The first step in getting answers to home energy consumption patterns

Whatever the size of your home, energy is being consumed every day, around the year. And while the utility bills might show you a monthly total, there are important questions about how energy is actually being used. Getting answers to these questions will help to conserve energy and save on seasonal energy costs. This is where an EnerGuide Rating can be valuable – it's the first step in getting answers to home energy consumption patterns. The rating will tell a homeowner exactly how energy efficient the home is. Better still, the EnerGuide Rating will clearly identify the areas of the home where a renovation, upgrade, or retrofit will increase efficiency and use less energy.

Government of Canada trademark

As an official Government of Canada trademark, the EnerGuide number rates the energy consumption and energy efficiency of your home.

To attain an EnerGuide rating for your home, a formal Energy Evaluation is required, including tests that assess air leakage, insulation performance, and overall energy efficiency. Bottom line, an energy efficient home saves energy, reduces greenhouse gas emissions, and reduces carbon footprints.
