I’ve seen a few articles written about whole house fans, mostly in US magazines and on web sites. Why aren’t they more popular here in Canada? They seem like an economical way to cool a house each evening.
Yes, whole house fans are a viable option for cooling in Canada, and some new homes even come equipped with them. Before the explosion in energy-gobbling central air conditioners, it was standard practice to keep windows closed during hot days, and open them at night. A whole-house fan boosts the speed of evening cool-down at a fraction of the energy consumption of air conditioning. With Ontario facing the prospect of electricity overload this summer, energy-frugal home features like whole-house fans make more sense than another nuclear power plant or two.
