Why should I retrofit my home?

Residents who invest in home energy upgrades can lower their energy bills, reduce greenhouse gas emissions, protect against energy price increases and improve the comfort in their homes. 

Below are some examples of the benefits of common deep retrofits:

Deep Retrofit How it Works Benefits
Heat pumps
  • Moves heat from one space to another: In the winter it warms by transferring heat inside and in the summer it cools by sending heat outside
  • Can be used for space conditioning and domestic hot water
  • Increases value of home
  • Reduces costs for electric heating, natural gas, and water heating
  • Requires less maintenance than combustion heating systems
  • Provides both heating and cooling
  • Safer than combustion-based heating systems
  • Can last up to 15 years


Insulation and air sealing (building envelope, ducts, windows, doors)
  • Slows the flow of air into or out of your home
  • Insulation slows the rate of heat loss
  • Air sealing prevents air leakage from places such as windows and doors 
  • Fewer drafts during the winter
  • Less noise from outside
  • Improves air quality as a result of less humidity, pollen, dust and pests
  • Better humidity control
  • Reduces heating and cooling costs


Smart thermostats with Zone Control
  • Divides your home into multiple zones, which allows you to set different temperatures for each space
  • Eliminates wasteful heating 
  • Creates more comfortable temperatures 
  • Reduces heating and cooling costs 


High Efficiency Furnace (Energy Star)
  • Results in less heating going to waste
  • High efficiency furnaces have over 90 per cent efficiency while older models typically have around 65 per cent
  • Uses less energy than other models
  • Longer lifespan than older models
  • Lower energy bills
  • Saves even more energy when paired with a smart thermostat


Solar PV options with battery storage
  • Converts sunlight energy into electricity
  • Source of renewable energy
  • Solar generated can be stored by battery (for power outages) 
  • Excess power can be sent into grid (get credit on bill with Net Metering)


What is the EnerGuide home evaluation?

Conducting an EnerGuide home evaluation(External link) can help you understand your home's energy use and identify areas for improvement. 

The audit is carried out by a registered energy advisor. Your energy advisor will examine the exterior and interior of your home to look for air leaks, indoor air quality, insulation levels, HVAC equipment, and much more.

Once the assessment is complete, you will receive customized recommendations in the form of the following documents: 

  • An EnerGuide rating and label
  • A Homeowner Information Sheet
  • A Renovation Upgrade Report


For more information on how to interpret your results, please visit Natural Resources Canada(External link).

How much does an energy audit cost?

The EnerGuide home evaluation typically costs between $400-600. Homeowners pay up-front for evaluations. However, a number of grants are available to cover the costs of the evaluation.

For programs such as the Canada Greener Homes Grant, you must complete the process in order to receive reimbursement for the pre-retrofit evaluation.

How do I complete a home energy retrofit?

The following steps summarize what to expect when undertaking a home energy retrofit:

1. Arrange an EnerGuide home evaluation

  • The post-retrofit evaluation will include:
    • a new EnerGuide rating and label
    • follow-up information indicating improvements to your home energy efficiency and your EnerGuide rating
  • Your energy advisor has up to 30 days to submit documents to Natural Resources Canada.
