I’ve been racking my brain lately thinking of what are good methods to increase internal airflow in a house with few windows, all facing the wrong direction to catch wind. What are your ideas?
Edit: Breaking a wall to make more windows isn’t an option.
Suck the air out. Pushing air in with fans creates a higher pressure zone in the house. You won’t move as much air. On the upper floors where it’s warmer suck the air out of what windows you have, but push the air in at the lower windows. Personally my house doesn’t have any windows, this is Lemmy we use Linux here.

I suppose that is an accurate comparison.
Attic fan. It is a game changer.
Attics aren’t a thing around here, unfortunately. I could get a warehouse-styled convection fan, but the cost is a bit spooky when I don’t even know if it’ll work.
Research and shop around for a type of fan called a centrifugal blower or utility blower. These fans are designed specifically for entire space ventilation. They sound like tiny jet engines. The same fans that inflate bouncy fun houses or the fans you sometimes see on a storefront wet floor during a rainy day to blow dry. Output rates of small units 100 to 500cfm (cubic feet per minute) will replace all air inside a 2-car garage space every hour. Mid range blowers 600-900cfm will replace that same air space every 5-10min (approx. 6x per hour). Higher velocity blowers >1000cfm will clear an entire 1-story house (typically for HVAC or factory use) and is more efficient and quieter than the biggest attic fan style unit.
After you have bought the raw power of air movement, then experiment with positive pressure and negative pressure flow setups (suck vs. blow). And then finally other per room or per window configurations as needed.
Thanks for the tip, it does seem quite interesting. From what I could find locally, prices are all over the place, so I’ll spend some time reading spec sheets haha
