Home Energy Retrofits 101

A home energy retrofit is a way to improve how your home uses energy by upgrading light fixtures, sealing windows/doors, adding solar panels, etc.

Twenty-five per cent of Ontario’s GHG emissions currently come from heating and cooling buildings, and our population is growing. Every step you take to reduce your energy use is a step toward a more sustainable future. Before starting any home renovation project, check with your home insurance provider to ensure it will not change your coverage.

  • 33 per cent of Oakville’s energy use 
  • 27 per cent of Oakville’s GHG emissions

EnerGuide home evaluations or home energy audits can help you understand how your home uses energy and identify potential retrofits that would be best for your home. 

  • Audits are carried out by a registered energy advisor
  • Audits will give you an EnerGuide rating for your home and an energy efficiency report to help you make decisions
  • Typically cost between $400 to $600
  • Homeowners pay up-front for evaluations, however, you may be eligible for grants or rebates to cover the costs of the evaluation through programs offered by Enbridge Gas or Natural Resources Canada

Rebates and incentives can be combined. Please review the details of each rebate to determine which ones you may be eligible for and would work best for you.

Some upgrades can be done quickly and easily with a little research and guidance. Bigger upgrades, like replacing a furnace, water heater, or boiler are recommended to be completed by a licensed HVAC contractor. Be sure to ask for credentials and check reviews when choosing a contractor.

You can find a Registered Energy Advisor through Natural Resources Canada's database.

  • Air sealing prevents air leakage from windows and doors
  • Fewer drafts during the winter
  • Utility bill savings
  • Less outdoor noise pollution
  • Improves air quality 

Solar PV and battery storage

Converts energy from the sun into electricity

Benefits

  • Source of renewable energy; reduces GHG emissions
  • Utility bill savings
  • Increases home value
  • Solar generated can be stored by battery (for power outages) 
  • Excess power can be sent into grid (on-bill credits with Net-Metering)
