When the sun hits the glass, not so much. Our retractable awnings are an
absolute neccesity.

Ah, awnings. They were on most every house when I was a kid, a long time
ago. Now we just stick a cooker box in the window and suck up electricity
instead. A decent tree can cool your house as much as a 12000 Btu AC and at
no cost.
