Each house stands for one in ten of Calgary's 379,710 houses (single-detached, semi-detached, row and duplex), drawn by when it was built. The glow shows the usual pattern: older houses tend to be leakier and less insulated. More snow in the drawing means more heating degree-days: a longer, colder heating season.

What an evaluation finds in Calgary homes

Of Calgary's 379,710 houses (single-detached, semi-detached, row houses and duplexes), 10% were built before 1961 and 47% before 1991, according to the 2021 Census. The typical Calgary house dates from 1991–1995, 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.

Calgary gets about 4,876 heating degree-days a year, a measure of how much heating its climate needs, and its winter design temperature, the cold day heating systems are sized for, is −26.2°C. Those figures come from the climate data for Calgary International in HOT2000, the home-energy software Natural Resources Canada (NRCan) gives energy advisors. That's about 24% more heating demand than the middle of the 70 cities we cover. A long heating season: air sealing and insulation pay back well, and every leak costs money for months.

Wildfire smoke reaches Calgary in some summers. The Government of Canada's advice is to keep windows and doors closed, limit exhaust fans and use the best filter your system can handle, so ask the advisor what your furnace or HRV can take.

In the Calgary area, 74% of households heat mainly with a forced-air furnace and 8% with a boiler and radiators; natural gas is the main heating energy for 73% of households and electricity for 13% (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.

What it costs in Calgary

There's no provincial rebate or price list; the City of Edmonton's guidance is to expect more than $400 and to get two or three quotes.

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 a home energy assessment (EnerGuide evaluation) 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.

Prairies Alberta, Saskatchewan and Manitoba

Calgary’s climate: Prairies

Long, very cold, very dry winters: air sealing, radon testing and humidity balance lead.

Heating is the big bill here: winters are long and very dry, and cold snaps reach −30°C to −35°C. Radon is common, and electricity prices vary widely between provinces, which changes what pays back. An EnerGuide evaluation should focus on air sealing, attic and basement insulation, a radon test and safe humidity levels.

In Calgary: Calgary's August 2024 hailstorm was the costliest in Canadian history, affecting about one in five homes, so check the roof before attic work. Electricity is pricey (about 23¢/kWh) and gas heats 73% of homes, so hybrid heat pumps often make the most sense.

  1. Seal the top and bottom of the house

    In deep cold, warm air rises and escapes through attic leaks while cold air is pulled in down low. Sealing both saves heat and helps prevent attic frost and ice dams.

  2. Test every home for radon

    The 2024 national survey found about 1 in 3 homes at or above Health Canada's guideline in Saskatchewan and Manitoba, and just over 1 in 6 in Alberta.

  3. Balance dry air against condensation

    Winter air is extremely dry, but humidifying too much frosts windows and can wet walls and attic sheathing. The colder it gets outside, the lower indoor humidity must be.

When to book: Book the evaluation between November and March, when cold weather makes air leaks and missing insulation easy to see. Start a 3-month radon test in the heating season, and check the attic after a cold spell.
