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. Also called a ‘net-zero’ home.
