Functional equivalent of air conditioning--open up your windows at night when its cool--get up early and close them all before it gets hot. Curtains and shade trees help a lot too. We're having mid90's currently but my un-AC'ed house is quite comfortable all day long. Just ordinary insulation too, nothing heroic there.

We do this too. It used to be really great when we had an attic fan that worked, but still does well with a box fan in the window.
