The first floor is a big rectangle divided into rooms (and a garage). The second floor is a smaller rectangle in the middle of that triangle under the roof. There are unused crawl spaces on the sides of the triangle, and an unused attic above the second floor.
There are louvers in the attic, so I'm wondering if fans up there blowing air out (and maybe airflow grates on the upstairs ceiling so heat can rise easily between the second floor and the attic) would help keep the upstairs cool. Has anyone done this?
