The glow shows the usual pattern: older houses tend to be leakier and less insulated. Snowfall scales with heating degree-days.

What the analysis shows

Ottawa gets about 4,354 heating degree-days a year and has a winter design temperature of −24.3°C, according to NRCan's HOT2000 climate data for Ottawa International. 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.
