How to Build an Energy Audit Summary Report
Add the property address, age, floor area, and province so the report reflects relevant rebate categories.
Rate the attic insulation, air sealing, window condition, and mechanical system efficiency based on what was observed during the walkthrough.
Enter each recommended retrofit with an estimated cost and expected annual savings so the report can rank them by payback period.
Click Generate Audit Report to see the estimated performance score and a prioritized retrofit list ranked by payback period.
Understanding Home Energy Audit Reports
A home energy audit turns a walkthrough into a prioritized action plan. Anyone can point at an old furnace and say it should be replaced, but a useful audit report ranks that recommendation against a dozen others by actual payback, so a homeowner or client knows where to start rather than facing an overwhelming list with no order to it.
What This Score Is and Isn't
An EnerGuide rating is the nationally recognized measure of a home's energy performance. It is expressed in gigajoules per year, lower is better, and according to Natural Resources Canada a rating of zero means the home produces as much energy as it uses. It comes from an evaluation by a registered energy advisor, including a blower door test for air leakage and a detailed assessment of insulation and mechanical systems. This tool instead produces a simple 0 to 100 performance score from four findings: attic insulation, air sealing, windows, and the heating system. A score of 100 means every finding is rated good and 45 means every finding is rated poor. That is useful for framing a conversation with a client, but it is not an EnerGuide rating and can't be converted into one. Several provincial and utility programs require the certified evaluation to qualify for funding.
Why Air Sealing and Insulation Usually Rank First
Air sealing gaps and topping up attic insulation are typically inexpensive relative to the energy savings they produce, which gives them a short payback period. Big-ticket items like full window replacement often cost far more per unit of energy saved, giving them a much longer payback period even though the windows themselves may genuinely need replacing for other reasons like comfort, condensation, or appearance. A good report separates "best financial payback" from "eventually needs doing anyway" rather than presenting one flat priority list. To see what air sealing alone could save in a particular house, the air sealing savings calculator is a quick companion to the figures entered here.
Rebate Programs Change, So Verify Before Promising
Federal and provincial retrofit rebate programs change eligibility rules and funding levels over time. The Canada Greener Homes Grant has closed, and the Canada Greener Homes Affordability Program for low and median income households is delivered through provincial partners in a limited number of provinces. Most other support comes from provincial and utility programs, such as Ontario's Home Renovation Savings Program, CleanBC Better Homes, Rénoclimat in Quebec, and the programs run by Efficiency Nova Scotia and Efficiency Manitoba. Natural Resources Canada keeps a directory of financial incentives by province and territory. This report lists the general categories that may apply for the selected province, but specific amounts and eligibility should always be confirmed directly with the current program before a number gets promised to a client.
Pairing With Other Reports and Tools
Once specific retrofits are prioritized, the energy savings report generator can run a detailed cost comparison for the mechanical system portion, and the carbon report generator can add the emissions angle if that matters to the client's decision. For a second opinion on the order of the work, the retrofit priority calculator is worth a look before the plan goes to the client.
Frequently Asked Questions
No. An official EnerGuide rating is expressed in gigajoules per year, where lower is better and zero means the home produces as much energy as it uses, and it comes from an evaluation by an energy advisor registered with Natural Resources Canada, including a blower door test. This tool's 0 to 100 performance score is a simplified index built from four findings, so it can't be converted into an EnerGuide rating and should only be used to frame planning conversations.
Retrofits are generally prioritized by payback period, which is the estimated cost divided by the expected annual savings, together with overall impact. Air sealing and attic insulation often rank highest since they tend to offer strong savings relative to cost. Big-ticket items like full window replacement often have a longer payback period and rank lower on a purely financial basis, even though they may still be worthwhile for comfort or aesthetic reasons.
No. Rebate programs vary significantly by province and change over time as funding is renewed or programs are updated. The Canada Greener Homes Grant has closed to new applications, and the federal Canada Greener Homes Affordability Program for low and median income households is delivered through provincial partners in a limited number of provinces, alongside separate provincial and utility programs. Always verify current program details and eligibility directly with the relevant program before promising a specific rebate amount to a client.
No. This report is a planning and communication tool for organizing findings and recommendations. Many provincial and utility programs require an EnerGuide evaluation from an energy advisor registered with Natural Resources Canada, not a self-generated estimate, in order to qualify for funding.
