Home energy audits in Trois-Rivières

Of Trois-Rivières's 39,825 houses (single-detached, semi-detached, row houses and duplexes), 21% were built before 1961 and 68% before 1991, according to the 2021 Census. The typical Trois-Rivières house dates from 1971–1980, and an evaluation is how you find out what that means for yours: the blower door measures air leakage, the advisor inspects the attic, walls, basement, windows and heating system, and the report ranks upgrades by what they'd save.

Trois-Rivières gets about 4,560 heating degree-days a year and has a winter design temperature of −25.2°C, according to NRCan's HOT2000 climate data for Nicolet. That's about 16% more heating demand than the middle of the 70 cities we cover. The more heating a climate needs, the more each fix is worth, which is why the evaluation's ranked list matters more in some cities than others.

In the Trois-Rivières area, 59% of households heat mainly with electric baseboards; electricity is the main heating energy for 79% of households (Statistics Canada, 2023). The heating system on the report shapes the recommendations: a forced-air furnace invites a ducted heat pump, electric baseboards a ductless one.

In Quebec, EnerGuide evaluations are booked through the provincial Rénoclimat program: the pre-retrofit evaluation costs $150 plus taxes, reimbursed when you receive financial assistance under the program, and the first post-retrofit evaluation is free.

• Initial evaluation, about 2–3 hours. The advisor measures and inspects the house and runs the blower door test.
• Report and EnerGuide rating. You get the home's energy rating in gigajoules per year and a list of recommended upgrades with estimated savings.
• Do the work. Most rebate programs only count upgrades done after the initial evaluation.
• Follow-up evaluation. A second visit measures the improvement, which is what most rebates pay on.
