What an evaluation finds in Nanaimo homes
Of Nanaimo's 33,520 houses (single-detached, semi-detached, row houses and duplexes), 15% were built before 1961 and 54% before 1991, according to the 2021 Census. The typical Nanaimo house dates from 1981–1990, 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.
Nanaimo gets about 2,939 heating degree-days a year and has a winter design temperature of −3.2°C, according to NRCan's HOT2000 climate data for Comox, the closest comparable location in that data set (87 km away). That's about 25% less 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.
What it costs in Nanaimo
There's no provincial price list; the City of Nanaimo quotes $400–$500 as typical for an existing home. Several B.C. municipalities subsidize evaluations for their residents (see local programs below).
- Home Energy Assessment Rebate: City of Nanaimo pays $150 toward an initial EnerGuide home energy assessment by a certified energy advisor (apply within 24 months of the receipt), and up to $200 for a follow-up assessment at $10 per 5 GJ/yr reduction in the EnerGuide rating (at least 5 GJ reduction). The advisor must hold a City business licence. The program page was last updated Nov 2024, is still listed on the City's rebates page, and may end without notice. Details
Most providers quote the initial (pre-upgrade) and follow-up (post-upgrade) visits separately. Rebate programs that pay on measured improvement need both, so ask for the combined price.
How it works
- 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.
