Cooling can work. Rehau does it. I learned details at one of their seminars a few years ago. Sorry, I've forgotten most details since then, but remembered the important thing: They do cooling.

Concerns about condensation are valid. Basically, your cooling load must not exceed the threshhold that leads to condensation. In Arizona, your numbers should work great. In Redmond, Washington, probably not. I'd contact Rehau to learn how to run those numbers for your location.
