The building interior gets hot during the day and stays hot during the evening when it is much cooler outside. It would be a really great option to simply vent the hot air outside instead of having to turn the air-conditioner on.
I'm looking for a more structural and long-term solution than just opening a window and propping a fan right next to it, something like a decent-sized exhaust vent to the outside with a switch-activated fan attached would be a good solution.
Is this something that has already been done and are there existing products or plans that can be referenced?
