Agreed but that’s sadly not the case for most US buildings.
Source? Generally, construction methods in the US include significant insulation especially in retail, office and residential construction. Malls and office buildings retain higher internal air pressures to keep the hot air from getting in. It's why many shops give you that cold air breeze when you open the door.
Presumably if the mall is well insulated and has doors that might not use that much energy?
The Superdrug I went into on Sunday afternoon was lovely and cool and had the doors wide open :( I suppose it's better from a Covid perspective.
