Passive ventilation (en.wikipedia.org)

Apparently turbine ventilators can reduce attic temps pretty dramatically, which in turn can passively reduce cooling costs by 15%.

Also bringing humidity down instead of the air temperature helps. -> wet bulb temperature

Reducing humidity by means of ventilation is way easier than reducing the temperature. That's because air has a really small heat capacity. Fresh/ inbound air is just effortlessly heated up by the walls.

It could help to compress the air outside before venting it inside, maybe. ;) https://en.wikipedia.org/wiki/Vapor-compression_refrigeration
