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.

Getting your usage history in Calgary

Most of Calgary is served by ENMAX Power for electricity and ATCO Gas for natural gas.

Alberta is a retail market: the distributor owns the wires and pipes, but you may buy the energy itself from a retailer. Your usage history sits with whoever bills you.

  • ENMAX Power: ENMAX Power (the wires company) doesn't bill homes, so usage history comes from your retailer's bills or online account, e.g. ENMAX Energy MyAccount for ENMAX retail and Rate of Last Resort customers. No distributor usage portal or Green Button found; the ENMAX MyAccount page only confirms bills and payments. Link

What the analysis shows

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. Weather-normalizing your bills against those degree-days separates heating from baseload (lights, appliances, hot water), so you can see how much of the bill a heating upgrade can actually touch, and compare a mild year with a harsh one fairly.
