Negative air pressure is your friend. If you open the windows upstairs and down and blow air out of the house it’ll suck air from the downstairs to the upstairs cooling the entire house.
Bernoulli’s principle is your friend. Rather than having fans right next to the windows you’ll move more air if you back the fans a meter or so from the window. https://youtu.be/BhWhTbins_A?si=9LGd0_EmfPFBNnDJ
would that principle still apply in the scenario of a window and wall being in the equation? I would imagine if that were true than more efficiency could be produced with a smaller fan inside ductwork vs a large unit which covers the entire cylinder size.
The fan sucks the air from all directions, except for the exhaust direction. If you place the fan next to the window, the sides will suck the air from the outside. And since this is where the outside air tries to get into the room, you’ll be exhausting fresh air non-stop. But if you move your fan a bit inside the room, the outside air will be able to get in and the fan will only suck the inside air.

Never heard of Beenoulli’s Principle before, thanks for sharing.
