New Shop Design help needed

[SSLance]

I'm actually very impressed with how cool the shop has stayed on the real hot days even BEFORE the AC was installed. Insulating the 6" walls was certainly the right call and once I figure out a way to screen the sun out of those (6) 4' x 4' windows it'll really be easy to keep cool.

Now, the house garage, that's another story... It is NOT insulated and the afternoon sun shines directly on the big and little garage doors. It's okay...as long as you don't open the doors or put a hot car in there...but make a run to the store in the afternoon on a hot day and park the car back it the garage when you get home and look out... It turns into an oven pretty quickly.

It doesn't affect the house as it's sealed off and insulated from the house nicely...but I need to figure out a way to get a fan in there to expel the hot air some how some way.
