Home Energy Evaluations

NRCan Registered Energy Advisors

  • Windfall's Home Energy Evaluations are done by Natural Resources Canada (NRCan) Registered Energy Advisors.
  • Our Energy Advisors will conduct a detailed, basement to attic audit of your house, it's energy use, systems, and building envelope.
  • The advisor will pin-point exactly where and how you are losing energy and money.
  • The energy assessment will also find causes of potential health issues such as dampness, drafts, air quality, and ventilation problems.

Blower Door Test

Find those nasty air leaks

Homes with air leaks are expensive to both heat and cool and can be uncomfortable due to drafts. A Blower Door test is an integral part of a Home Energy Evaluation and will find those nasty leaks. Blower Doors are used to depressurize your house allowing air leaks to be identified. You may be very surprised to discover how many small air leaks your home has — which when added together may be the equivalent of one very large gaping hole!

Know Your Energy Rating

When your Energy Evaluation is complete, you will be provided with a customized written report which includes your home's EnerGuide Rating and label — plus a checklist of recommended upgrades to improve the energy efficiency, health, and comfort of your home.

Whether just thinking things through, hiring a contractor, or planing a DIY project, your energy advisor will go over all your options and the most cost effective upgrades to best fit your budget.

What to Expect During a Home Energy Evaluation

The energy evaluation is conducted on-site at your home. The initial (pre-upgrade) evaluation takes approximately 2–3 hours. A second (post-upgrade) evaluation takes up to 1 hour.

The energy advisor will conduct a basement-to-attic assessment of your home's insulation, heating, cooling, and other energy use.

A blower door test will be conducted to test for air leaks, which can cause wasted energy, uncomfortable drafts and poor air quality.

Your home will be given an energy rating using the Natural Resources Canada rating system — the lower the rating the better.

You will receive a full report outlining recommendations for improvements to help reduce your energy bills and increase your home's comfort.
