Provinces are now switching from the previous 0-100 rating label to the new gigajoules label.

Depending on where you live, your home may have one of these two labels:

EnerGuide Rating: 0-100 scale

The EnerGuide rating is a snapshot of the home's energy performance at the time of the evaluation.

It is the energy efficiency score of your home and it ranges between 0 and 100. The more efficient a house, the higher the rating number:

0 represents a house with major air leakage, no insulation and high fuel consumption. In other words, a house with poor energy efficiency and high utility costs.

100 represents an airtight and well-insulated house where energy purchased and energy generated, through renewable sources, is equal. This is also called a 'net-zero' home.
