If you use good insulation techniques while building, you barely need AC. Grew up in a country with harsh winters and hot summers -- you just open small window at night and close it in the morning, and your house stays cool for the day.

- agensaequivocum 5y agoDoesn't work in places like Phoenix where it's 100F at 10pm and doesn't dip below 80F or 90F before the rising the next day.
- cratermoon 5y agoDoesn't work where the humidity is high either.
