The air cooling units can work well but ideally the windows do need to

Presumably this is so the fans cause the air to be drawn through the
whole upper deck from the vents at the front? That said, these units
(while very effective at preventing steam-up and making buses not
smell of buses any more) do not provide any perceptible cooling
effect, as they don't move enough air, hence why the windows end up
open.

They aren't air-cooling units, IOW, they're just extractor fans.
