Everyone looks at me crazy when I bought a direct solar powered AC window unit. It was expensive, but i know my family has a backup while in building our passive cooling home.

The architecture angle is very telling. Architecture used to be the technology, and buildings were designed to resist overheating in summers (think of the large covered porches and cross-ventilation designs in houses in the U.S. South). Modern building abandoned almost all of those older techniques, and now building are built to retain and absorb heat; air conditioning is taken for granted.

Wanting to decrease air conditioning will require a return to the type of architecture that resists, rather than generates and traps, heat.

I write this as someone who doesn't have air conditioning, but who does live in a small, first-floor apartment with a window in the front and a window in the back and an open space from one to the other for cross ventilation. The building also has a large from porch that is covered, blocking direct sun rays from hitting the exterior walls. I use long-forgotten techniques to make my home tolerable in the summers (high temperatures are forecast to reach 100 degrees F in a couple of days), but that opportunity is available to me because of the architectural features of this old building.
