How Richmond is built

Richmond's houses by when they were built Ten house shapes, one for each tenth of Richmond's 46,950 houses. Before 1961: 5%, 1961–1990: 45%, 1991–2000: 21%, 2001 or later: 31%. Older houses glow hotter.
  • Before 1961 5%
  • 1961–1990 45%
  • 1991–2000 21%
  • 2001 or later 31%
Each house stands for one in ten of Richmond's 46,950 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. Snowfall scales with heating degree-days.

Why the design temperature matters in Richmond

−4.4°C is the 5th-mildest design temperature of the 70 cities we cover. The F280 calculation works out how much heat each room loses on that design day, from the house's actual walls, windows, air leakage and ceiling insulation.

With a design day that mild, a heat pump sized to the calculation can carry most or all of a typical Richmond house's heating load, which makes sizing it right, rather than oversizing it, the main job.

In the Vancouver area, 32% of households heat mainly with a forced-air furnace, 31% with electric baseboards, 12% with a boiler and radiators and 5% with a heat pump; natural gas is the main heating energy for 42% of households and electricity for 39% (Statistics Canada, 2023).

What CSA F280-12 asks for

The National Building Code 2020 requires the heating capacity for a house to be worked out with CSA F280, and its list of referenced documents names the 2012 edition, CSA F280-12. Provincial codes can name their own edition and climate values, so ask your designer which ones the calculation uses.

Why skipping it costs money

Contractors who size by square footage routinely oversize. An oversized heat pump costs more to buy, cycles on and off, dehumidifies poorly in summer and wears faster. An undersized one leans on backup heat. The F280 report is the evidence either way, and it's worth having before you compare quotes.

What it costs

About $150–$400 as a standalone calculation (a September 2026 planning range; quotes vary). Many energy advisors bundle it with an EnerGuide evaluation, which also gives the calculation measured air-leakage data instead of an assumption.

NRCan-licensed service organizations serving Richmond

Many energy advisors also do room-by-room CSA F280 calculations for an extra fee; HVAC designers do them too. Ask for the F280 report itself, not just an equipment recommendation.

Heat loss calculation in Richmond: common questions

What design temperature is used for heat pump sizing in Richmond?

NRCan's HOT2000 climate data gives −4.4°C for Vancouver International. Your designer may use the building code's design value for Richmond, which can differ slightly; ask which one 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?

About $150–$400 standalone as a planning range; often less when bundled with an EnerGuide evaluation.

Who does F280 calculations in Richmond?

Many of the 27 NRCan-licensed organizations serving Richmond offer them, as do HVAC designers. Ask for the F280 report itself.

Do rebate programs require a heat loss calculation?

Requirements vary by program and change often. Even where it isn't required, it is the best protection against an oversized or undersized system.
