When I had my house in AZ, I had a contractor friend turn my attic into an Igloo cooler. We added insulation between the rafters, up to the roof decking, held in place with wire mesh. The house was evap cooled, with up-ducts venting into the attic. We also added gable fans in thermostats at either end of the attic, set to come on when the attic reached 105 degrees.
Once it was all done, my colling bill was 1/3 of what it had been and the house was a lot cooler (55 degrees vs. 78).
