How to keep an old house cool?
Hi everyone, we've moved into an old 100-150 year old two-story house. We're up in Eastern Canada, where the winters used to be colder than they are now, and the summers cooler as well, so this house has lower (7 foot) ceilings upstairs than the usual 8 feet.
As summer approaches, it's going to get hot upstairs. The windows are nicely spaced for natural airflow, but I'm wondering what other ways there are to cool the upstairs. The ceilings are too low for ceiling fans, but maybe a few well placed tabletop fans? What other tricks can we explore? We don't want air conditioning, because in Green Wizards style, we're trying to reduce our energy usage. I suppose fans use energy, too, but not nearly as much as air conditioners, I would guess.
Thanks in advance!
