Most buildings are air conditioned. The way they are built they would not be habitable without it.
Consider baseball, a game that is famous for fresh air and sunshine. They erect a building to keep out the fresh air and sunshine. They poke holes in it to let in fresh air and sunshine. They put glass and curtains in the holes to block the fresh air and sunshine. They put electric fans and lamps inside to simulate fresh air and sunshine. Then they put an expensive motorized roof on the building to let in fresh air and sunshine.
