Keeping it Cool Without Air Conditioning

In really hot countries air conditioning in buildings might seem like a necessity; however, it is possible to design buildings that stay cool in the heat without even using electricity. In Burkina Faso there is a school that was specially designed to stay nice and cool by manipulating airflows.

There’s not much electricity to go around, Kéré says. “So there is no air-conditioning. It’s too expensive for a country like Burkina Faso.”

So when he designed this secondary school for Dano in his native land, he built it with innovative, elegant, distinctive and yet simply constructed split-level roofing and ceiling structures that funnel warm air up and out of the buildings.

Tall window slats that can be adjusted control both light and heat. Three to a room, they pull air into the classroom. Heat rises.
To use that movement of air, a series of narrow “chimney” gaps between the convex wave shapes in the highly insulating concrete and brick ceiling pulls the hot air up and out the roof.
