What the analysis shows
Greater Sudbury gets about 5,049 heating degree-days a year and has a winter design temperature of −27.7°C, according to NRCan's HOT2000 climate data for Sudbury. 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.
