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.
|Type of House||Rating|
|New House build 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|
For a brand new house, a rating of 80 or higher is excellent.
