Cooling Rates of Houses During Extended Power Failures
It's a big concern for most Canadians if the power goes out during the winter for any length of time. While the indoor temperature will start to fall almost immediately, it turns out that it will typically take many days to fall below 0°C, unless abnormally severe conditions exist. While the indoor air temperature may fall to 14°C or so quite quickly, the materials that make up the house will take much longer to lose their temperatures. The earth around the basement has a high thermal mass and adds heats, and there can be incidental gains from the sun or occupants. Homeowners faced with extended power outages can take several days to protect their possessions from freezing.
