How Red Deer is built

Red Deer's houses by when they were built Ten house shapes, one for each tenth of Red Deer's 31,405 houses. Before 1961: 8%, 1961–1990: 39%, 1991–2000: 14%, 2001 or later: 40%. Older houses glow hotter.

  • 2001 or later 40%
Each house stands for one in ten of Red Deer's 31,405 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.

Where CO alarms go: installation rules in Alberta

What the rules say about installing alarms:

  • Required in new homes with a fuel-burning appliance or an attached garage; for existing homes the province calls them highly recommended.
  • Alberta's fire code requires CO alarms that are installed to be inspected, tested and maintained following the manufacturer's instructions.
  • For new houses, the National Building Code 2020 (Article 9.32.3.9) requires a CO alarm inside each bedroom or within 5 m outside each bedroom door when the home has a fuel-burning appliance or an attached garage, an alarm in any room with a solid-fuel-burning appliance (on or near the ceiling unless the maker's instructions say otherwise), and interconnected alarms in a house with a secondary suite.

CO sources in Red Deer homes

In the Red Deer area, the main heating energy is natural gas for 83% of households (Statistics Canada, 2023). Any fuel-burning appliance, fireplace or attached garage is a potential CO source.

Single-detached houses make up 53% of Red Deer's households; many have an attached garage, another reason to put an alarm near the door into the house.

What a CO check involves

  • Alarms next to sleeping areas and on every storey, tested monthly and replaced by their end-of-life date (usually 7 to 10 years).
  • Annual service of fuel-burning appliances by a licensed technician.
  • A combustion spillage test during an energy evaluation, which catches a venting problem before it produces CO.

What this means in Red Deer’s climate

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.

  • Check gas appliances after tightening. Most homes here burn natural gas. Air sealing can depressurize the house and pull exhaust back inside, so appliances need a combustion safety test and working CO alarms. Ask: Ask for a combustion safety test during the blower door visit, and again after air sealing.
