EnerGuide E Evaluation

This service provides an EnerGuide evaluation focused on confirming building conditions, typically after a renovation or HVAC system upgrade. It reflects the final or as-built performance of the home using standard operating conditions as defined by Natural Resources Canada.

How We Perform the Work:
We attend the site, observe relevant changes to the building, conduct a blower door test and update the energy model using final construction details, installed equipment, confirmed envelope assemblies, and blower door testing results.

Scope of Work Includes:

• Review of final construction information.
• Confirmation of installed mechanical systems and envelope details.
• Incorporation of blower door testing results, where applicable.
• Final update of the EnerGuide model.
• Preparation of final EnerGuide documentation or summary.

What’s Included 

Blower Door Airtightness Test
A blower door test is performed to measure how much air leaks through the building envelope. The test depressurizes the home using a calibrated fan, allowing us to pinpoint leakage pathways.
Testing follows NRCan and CGSB standards. Because EnerGuide requires an “as-operated” test, guarded blower door testing is not permitted; as a result, shared or party walls cannot be isolated or evaluated with precision.

Official EnerGuide Rating & Report
Your final report includes an official EnerGuide rating, presented in gigajoules (GJ) per year and normalized energy intensity (GJ/m² or GJ/ft²). These metrics give a clear, standardized measure of your home’s performance and make it easy to compare efficiency across different homes and designs.
