How do you determine the EnerGuide rating of a home?

Answer

All of the components of the home including window styles and orientation, insulation amounts, HVAC systems as well as the air tightness of the structure will be recorded and entered into computer modeling software by a Certified Energy Advisor.  Using climate data compiled by Environment Canada, the advisor will be able to estimate what the yearly energy costs of the home will be as well as issue an official EnerGuide rating.
