EnerGuide Assessment

An EnerGuide assessment is a full inspection and analysis of the energy efficiency of your home. To ensure accuracy your energy advisor will need to:

  • Take photos of your home's exterior, attic & mechanical equipment, for Quality Assurance review.
  • Measure the house envelope to determine ceiling, wall, and basement exposed surface areas and calculate the heated volume.
  • Orient and identify types of windows & doors to account for heat losses & solar gain.
  • Measure and determine insulation levels/values in the ceilings, walls & basement.


For more information please refer to this Presenetation.

Check the fuel, types & efficiency of:

  • Furnace
  • Air Conditioning system
  • Heat Pumps (air source or ground source)
  • Water Heaters
  • Fireplaces
  • Heat Recovery Ventilator (or other air changing system)


Perform a Blower Door Test to determine the overall air-tightness of your home.


Critical areas to inspect for air leakage include:

  • Attic hatch
  • Electrical receptacles, switches, fixtures
  • Windows & doors
  • Basement Header (rim joist) Exhaust fans
  • Furnace & water heater chimney
  • Fireplace
  • Other penetrations

Initial findings are discussed with you, including cost-effective recommendations for energy efficient improvements.

More Info

Upon completion of all calculations and entry of data into a computer simulation of your home, a comprehensive Homeowner Report is mailed to you which includes:

  • An EnerGuide rating of your home as it exists
  • A Potential Upgrade EnerGuide rating - what it will be if recommendations are implemented
  • Air Change Rate (ACH)- how many times per hour the air is changed in your home
  • Equivalent Leakage Area (ELA) - combines all the leakage into 1 opening
  • Potential Government grants
  • Recommended upgrades
  • Air leakage points of concern
