How Green Venture Can Help You: EnerGuide Home Evaluations

A person conducting an energy audit reading inside of a house.

The Green Venture EnerGuide evaluation team is your starting point for embarking on your retrofit journey! We’re dedicated to uncovering methods to boost your home’s energy efficiency, enhance comfort, and decrease greenhouse gas emissions. An EnerGuide Home Energy Evaluation, performed by a Natural Resources Canada Registered Energy Advisor, is required to be eligible for the Canada Greener Homes Loan.

Optimal timing for an evaluation is during home renovation planning, as it’s typically easier to incorporate insulation or other upgrades. Our team of Energy Advisors is here to maximize your renovation efforts and streamline your application process. Additionally, an evaluation pinpoints trouble spots in your home, providing insight into energy and cost-saving solutions.

Here is a guide to the EnerGuide label you receive after an evaluation

An evaluation can help you:

  • Lower your energy bills
  • Set priorities for home renovations
  • Fix moisture problems, drafts, etc.
  • Make your home more comfortable
  • Access government incentive programs

Best of all? Home energy renovations play a crucial role in slashing greenhouse gas emissions, aiding us in achieving our local targets. Plus, they boost the local economy by supporting businesses involved in the renovation work and the sale of materials. It’s a win-win situation for both the environment and our community!

Energy Audits FAQ

About Energy Audits in General:

  • An EnerGuide Home Evaluation (or an energy audit) is a basement-to-attic home inspection that calculates the total energy consumption of your house.
  • Can help you understand how your home uses energy now – and identify upgrades to help improve energy efficiency in the future.
  • This will give you an EnerGuide rating for your home. You can also get an energy efficiency report to help you make decisions about doing retrofits or upgrades.
  • An energy audit looks for air leaks and drafts, gaps around doors and windows, poor air quality, poor insulation levels and more.
  • When you are planning any renovations that involve your furnace, water heater, windows, doors or insulation.
  • When you are planning major renovations.
  • If your house is hard to heat or your energy bills are high.
  • If you want to know the best way to reduce your greenhouse gas emissions.
  • If you are experiencing poor air quality or are observing mold and mildew.
  • The initial audit takes about 2 hours, and the follow up audit takes about an hour. This can vary depending on the size and complexity of the home.
  • Energy auditor will measure your home and determine the specifications of all heating equipment.
  • The energy auditor will determine the amount of existing insulation in your attic, walls and basement. 
  • A blower door will be temporarily set-up in an exterior doorway to measure the amount of air leakage in the whole house.

Home Winterproofing

Over the past two years we have been a delivery agent for Enbridge’s Winterproofing Program to target older homes with low insulation levels to reduce and save on energy use every month. As we are no longer taking applications for the program please click here for the new authorized delivery agents.

Our goal has been to minimize the amount of energy flowing out of older homes in the Niagara Region to ensure comfortable temperatures throughout the winter. This has allowed for households to not only reduce their greenhouse gas emissions but has also helped keep energy prices affordable by improving on existing homes. We are so grateful to our Energy Programs team including the Registered Energy Advisors that have helped make these reductions possible. For more information on the program and to apply online please visit Enbridge Gas’ information page. Please call 1-844-770-3148 to apply over the phone.

We wish all the households we retrofitted an extra cozy winter and many more joyful moments at home!
