seems like a good idea to ventilate the house at night and button it up
during the day, especially if you have lots of thermal mass inside,
eg masonry walls.

last year i hung a 32' x 16' piece of black 80% sun-absorbing greenhouse
shadecloth across the whole front south wall of my house. an interesting
look :-) it also comes in green, white, red, beige, gunmetal gray... mine
cost about $70, including shipping, from stuppy at (800) 877-5025. a local
commercial greenhouse supplier should have this too. getting it made up in
the size you want with hems and grommets might take 2 weeks. it lasts 5-10
years, and keeps about 800 btu/ft^2/day of sun out of the windows in august
where i live, reducing the heat load for my house by about 77k btu/day, like
a 5k btu/hour window air conditioner running 15 hours a day. if you put a
couple of poles and guy ropes out in the yard, you might make a nice awning
and shady place...
