EnerGuide Rating

An EnerGuide rating shows a standard measure of your home’s energy performance. It shows you (and future buyers) exactly how energy efficient your home is.

The rating is calculated based on standard operation assumptions so that you can compare the energy performance of one house against another. The home’s energy efficiency level is 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 requires no purchased energy on an annual basis.

The following table outlines the standards for EnerGuide Ratings:

Typical Energy Efficiency Ratings

Type of House Rating
House built to building code standards 65-72
House with some energy-efficiency improvements 73-79
Energy-efficient House (New Home standard is now 80) 80-90
House requiring little or no purchased energy 91-100


For a brand new house, a rating of 80 or higher is excellent. The Efficiency Nova Scotia Demonstration Home will have an EnerGuide rating of 92-94.
