Here in Pleasant Hill we have a variety of passive cooling methods built in to avoid the need for central air. First is a metal reflective roof, then metalized insulation sheets under the roof, then 2 x 6's instead of 2 x 4's giving thicker walls and more insulation. Most of us have whole house fans, to blow off the hot air and suck in the cool at night. We have double-paned windows and many have double-celled mini blinds which we keep closed in the heat of the day. There might be a couple things I missed, but those are the major ones. I moved here from SF, where it's always cool. Chuck Durrett promised us it would work, but I was not a believer till I saw it in action. I came home to my house each summer day (days it was often 90-100) out here, to a house that was 75 degrees cool (felt like air con) downstairs, and at worst 80 upstairs. Each night when it cooled off I ran my whole house fan for 1/2 hour, and cooled the whole place down. There were only 2-3 nights the whole summer when I was too warm, and that could have been fixed by getting my ceiling fan up in the bedroom! Chuck claims this works in places as hot as Tucson. I almost believe him!
