About Energy Ratings | Know Your Energy Score


Why should you get an energy score?

An energy score is an energy rating that is provided after a home energy audit is completed. The higher the score, the more energy efficient your home is. When you complete an energy audit and receive an evaluation of your home’s current energy use, you’ll be given an energy score, using the Natural Resources Canada’s EnerGuide Rating System. An EnerGuide rating is a standard measure of your home’s energy performance. Your home’s energy efficiency level will be rated on a scale of 0 to 100. A rating of 0 represents a home with major air leakage, no insulation and extremely high energy consumption. A rating of 100 represents a house that is airtight, well insulated, sufficiently ventilated and incorporates highest efficiency equipment. The higher your score the better.

Why should you get a new energy score after upgrading the energy efficiency of my older home?

During your pre-retrofit energy evaluation, you’ll get recommendations on upgrades you can make to improve your home’s energy efficiency. Once you complete all (or even some) of the energy upgrades (also called retrofits), a post-retrofit evaluation will give you your home’s new and improved energy score. When you compare the two scores, you’ll be able to see the impact your retrofits have made. Knowing your energy score could have future benefits as well. With more and more Canadians looking for ways to conserve energy and make environmentally responsible choices, having a high energy score will be a selling feature for your home. So in addition to saving on your monthly energy costs right now, you’ll reap additional rewards when you sell. Check out our Home Rating program for more information.
