EnerGuide Rating

We received a new energy efficiency rating of 70 for our house. The rating was 49 prior to our recent improvements, and that number was given to us after we installed spray foam insulation to go from R0 to R20 on our first and second floor walls, so the original number for our house would have been even lower than that.

For perspective, here are the ratings provided online for various types of houses:

• New house built to building code standards: 65-72
• New house with some energy-efficiency improvements: 73-79
• Energy-efficient new house: 80-90
• House requiring little or no purchased energy: 91-100

We plan to make some more improvements to our home that should help with energy efficiency (i.e. vapour barrier and drywall in basement and sunroom, new front and side doors), so in the end our house should be somewhere in the mid-70s according to this scale (the target number for our style of house is 74).
