It was the best of times, it was the worst of times. (Don’t worry; that’s the end of the literary pillaging.) I poked my head outside this afternoon at 5 PM, thinking that maybe I should open the windows to warm the place up a little. As I go outside, I noticed that the neighbor’s AC unit was running. The inside temperature in my home was 72º, outside was 88º. So why am trying to warm up and the neighbor cool down?
Several reasons as it turns out. I’m living in an ICF (insulated concrete form) house that has one of our whole house fans installed. Whereas the neighbor’s house is a low mass stick framed house, and certainly has no whole house fan.
Of course whole house fans are great – but what seems to be a great combination is lots of mass to store “coolth” (made up word meaning the opposite of heat). I’ve been able to survive quite well all summer with just a whole house fan for cooling – no AC. That said,during the second week of 105º days, AC would have been nice for about 4 hours per day.
