The EnerGuide for Houses from Natural Resources Canadas’ Office of Energy Efficiency offers unbiased, detailed home energy evaluations by licensed advisors. Based on a particular home and homeowners’ goals and resources, the advisor will create a list of what updates will be most cost-effective. This could be a five or ten year plan, for every home it is different. Included in the evaluation, which will last between two and five hours will be:
- A “blower door” test to find air leaks.
- A printed report that shows where your energy dollars are being spent and a prioritized list of what you can do to improve your homes’ energy efficiency.
- An EnerGuide for Houses rating label that shows you how energy efficient your home is compared with others, from a low of zero to a top rating of 100, with each point increase representing a three to five percent reduction in energy use. As a reference point, R-2000 homes score a minimum of 80. With energy-efficient updating, older homes can typically reach the mid-70s.
- A second test is also available after renovations have been completed that will provide a new EnerGuide number.
