The Energy Evaluation Process

Step 1:

The homeowner contacts an EnerGuide Rating System service organization to select a Natural Resources Canada (NRCan) certified energy evaluator in their area.

Step 2:

The energy evaluator visits the home to enroll and label the home in the program.

Step 3:

The energy evaluator undertakes an analysis of the home with as much information as possible, noting all components that will affect the energy efficiency of the house. These components could include mechanical equipment, windows, building envelope, insulation levels, etc.

Step 4:

The energy evaluator inputs this information into NRCan's energy simulation software to determine the estimated annual energy usage and EnerGuide rating for the house. The energy evaluator will also do a blower door test to determine the air tightness of the home. A blower door test measures the home's rate of air leakage.

Step 5:

The energy evaluator also provides variations of the simulation that include energy efficient upgrades, which improve the energy performance of the home. An energy evaluator will recommend what upgrades can be done to improve the home's performance and the projected rating if the suggested improvements are done.

Please note: The energy evaluator ensures that good building science principles are maintained.

Step 6:

After the data has been collected, the homeowner is provided with the evaluation report and an official label that shows the EnerGuide rating of the home. This label should then be affixed to the electrical panel.

Step 7:

If the homeowner elects to make the recommended changes, the energy evaluators can return to the home to conduct a new energy evaluation. On verification of the upgrades, the homeowner may be eligible for rebates on their investment.
