This page covers Prince George and the Regional District of Fraser-Fort George, and Dawson Creek, Fort St. John and the Peace River Regional District. No city we cover is within 390 km, so the energy advisors listed here come straight from NRCan's list for Prince George, Dawson Creek and Fort St. John postal codes.
Design temperatures across Northern BC
The National Building Code of Canada 2020 says the 2.5% January design temperature is the value ordinarily used to design heating systems. Its climate table lists these British Columbia locations in or next to Northern BC:
| Location in the code’s table | January 2.5% design temperature | Heating degree-days |
|---|---|---|
| Prince George | −32°C | 4,720 |
| Mackenzie | −34°C | 5,550 |
| Dawson Creek | −38°C | 5,900 |
| Fort St. John | −35°C | 5,750 |
| Chetwynd | −35°C | 5,500 |
| Taylor | −35°C | 5,720 |
Environment and Climate Change Canada's 1981–2010 climate normal at Prince George STP (4.0 km from Prince George) is 4,673 heating degree-days a year, with a January mean of −6.7°C. At Dawson Creek Airport, 4.0 km from Dawson Creek, the normal is 5,870 heating degree-days, with a January mean of −13.2°C.
What CSA F280-12 asks for
The code requires the heating capacity for a house to be worked out with CSA F280, using the code's own design temperatures, and its list of referenced documents names the 2012 edition, CSA F280-12. The calculation works out how much heat each room loses on the design day, from the house's actual walls, windows, ceiling insulation and air leakage.
At −38°C, even cold-climate heat pumps lose capacity just when you need heat most. The room-by-room number tells you how much the heat pump can cover and how much backup heat to plan for, instead of guessing from square footage.
In B.C., the provincial Home Renovation Rebate's heat pump requirements call for a CSA F280 heat load calculation, so ask for the report with your quote.
What the calculation needs from your house
Of the 42,520 houses in the eleven municipalities listed here (single-detached, semi-detached, row houses, duplexes and mobile homes), 11% were built before 1961 and 69% before 1991, according to the 2021 Census. In an older or renovated house, the walls, windows and air leakage rarely match the original plans, so ask the designer to measure rather than assume. Have this ready:
- Room dimensions and ceiling heights, or a floor plan.
- Window and door sizes and types, room by room.
- Insulation levels in the attic, walls, basement and any floor over an unheated space.
- A blower door result from an EnerGuide evaluation, if you've had one.
- Where the ducts, radiators or baseboards run, so the heat can be delivered room by room.
What it costs
There's no standard published price for a standalone F280 calculation, so ask two or three providers for a written quote that names the deliverable: the room-by-room F280 report, not just an equipment size. Many energy advisors bundle it with an EnerGuide evaluation, which also gives the calculation measured air-leakage data instead of an assumption. Ask whether a rural travel fee applies. The CSA F280 heat-loss calculation explains the method and typical cost bands.

Heat pump programs in Northern BC
Heat loss calculations in Northern BC: common questions
What design temperature is used for heat pump sizing in Prince George?
The National Building Code 2020's climate table gives −32°C for Prince George, −34°C for Mackenzie, −38°C for Dawson Creek, −35°C for Fort St. John, −35°C for Chetwynd and −35°C for Taylor. Provincial codes can use their own climate tables, so ask which value the calculation uses.
What is CSA F280-12?
The 2012 edition of CSA F280, Determining the required capacity of residential space heating and cooling appliances. The National Building Code 2020 requires heating capacity for a house to be determined with it.
How much does a heat loss calculation cost?
There is no standard published price. Ask two or three providers for a written quote for the F280 report, and ask whether it costs less bundled with an EnerGuide evaluation and whether a travel fee applies.
Who does F280 calculations in Northern BC?
Many of the 16 NRCan-registered organizations that list Prince George, Dawson Creek and Fort St. John postal codes offer them, as do HVAC designers. Ask for the F280 report itself, not just an equipment size.
