COMMENT OF THE DAY: HOW THEY DID IT BEFORE AIR CONDITIONING “At the risk of stating the obvious, the reason for the interior corridor windows and clerestory, as well as the central corridor slot with metal grid, is for chimney effect for ventilation in the pre-AC days. Apartments of this vintage often had to resort to innovative ways to get ventilation, like the angled window bays of Wilshire Village. The grid looks like it’s part of the floor of the second floor corridor, which would be perfectly reasonable if you’re trying to create a walkable but air-permeable floor.” [marmer, commenting on Taking on a Rough Midtown Trio]
Well that definitely ‘splains it. It makes sense. Thanks marmer!
