I wonder how much we could reduce A/C usage by changing how we build. Contractors seem ignorant of traditional practices that used to help in part no doubt because they think they can throw A/C at bad design.

For instance, what if we used masonry instead of wood frame houses (masonry tends to insulate better; look at infrared pictures of American wood frame houses and European masonry). Also, orienting houses in proper relation to the sun and arranging rooms in a way that facilitates better air flow (embrace the summer draft). Also, evaporative cooling. I am not proposing we eliminate A/C, only find ways and build in a way that allows us to cool houses for cheaper or even for free.
