Comment on The interior of your house is hot, the exterior cool. What would the most efficient orientation be for a box fan? Pushing hot air out of a window or pulling cool air in through it?

  I’m glad to see someone linked to this video. No one ever believes me when I tell them this is the way.

  This guy seems to have a different goal then OP. He just wants the max airspeed in other parts of the house

    The goal is the same.

    Scenario: cold air outside, hot air inside.

    Goal: replace hot air inside with cold air outside.

    Method: open one intake window and one exhaust window. Use a fan to blow hot air out the exhaust window while the low pressure vacuumed created inside will cause cold air to be sucked in through the intake window.

    Maximize efficiency of method: follow video posted.
