Energy efficiency renovations include measures such as adding insulation, caulking and weatherstripping, improving or replacing windows and doors, and upgrading the mechanical systems.

It is important to understand that a house operates as a system. Besides occupant activities and the external environment (e.g. temperature, wind, rain, air quality and noise) the elements of a house such as insulation levels, airtightness, window and door types, ventilation rates, heating and cooling systems all affect each other and this combination affects the overall house performance. For example, even if you are investing in new heating and cooling equipment or new windows and doors, you cannot optimize the energy performance of your house if you are not keeping heat in during the winter and out during summer.

Insulation upgrades coupled with air sealing are among the most cost-effective home retrofits. This simple home improvement sometimes pays for itself in less than a year and continues to payback for the life of the house. This upgrade may also reduce loads on heating and cooling equipment allowing for smaller and more efficient systems.

  • Energy efficiency. Retrofitting costs less than producing new energy supplies to heat a house. More than 16 percent of Canada’s annual energy goes to heat our homes, and this energy comes mostly from non-renewable resources such as oil and gas.
  • Comfort and health. A well-insulated, air sealed and ventilated house makes for a comfortable home. It is also much quieter, and there is less dust and pollen to worry about.
  • Durability. By retrofitting your home you can also improve air and moisture control. As a result, your house will remain in better shape and last longer.
  • Save money. Improving a home’s energy efficiency is one of the best investments you can make, paying tax-free dividends immediately in the form of lower energy bills.
  • Protect the environment. Consuming less energy means fewer greenhouse gas emissions. Furthermore, retrofitting uses fewer new resources than building a new house.
  • The intent is to rate the energy performance of a house and its installed equipment under standard operating conditions
  • It is not a detailed energy performance and heat loss/heat gain audit based on the occupants or their lifestyle-related energy consumption
  • Nor is it an indoor air quality assessment, or a “home inspection” that provides a detailed assessment of the overall condition of the house
  • Basic Service Outputs:
    • Homeowner Information Sheet
    • EnerGuide Label
    • Guide to the EnerGuide Label for Homes
  • The purpose of the RUS is to assist homeowner and renovators with renovation strategies that can result in energy savings, financial savings, improved comfort and a reduction in greenhouse gas emissions.
  • The intent is to develop upgrade recommendations based on input from the homeowner and the information about the house collected during the Basic Service.
  • This service provides the energy advisor with the opportunity to educate the homeowner by explaining the benefits of each proposed upgrade and the way these upgrades should be prioritized
  • The upgrade recommendations are presented in the form of a roadmap. The homeowner is provided with multiple output formats for understanding the energy advisor’s recommendations:
    • A visual roadmap graphic
    • A table summarizing individual and cumulative energy savings
    • Recommendations that include target efficiency levels
    • Rationale statements for each recommendation
    • Details on key aspects of each recommendation
    • Links to other sources that will help the homeowner learn more about the recommended upgrades
    • Key considerations involved with each upgrade
