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

we call these "canadian wells" here, or air/ground heat exchangers, it's nothing new

Old things can be interesting. Or new to anyone who didn't know about them.

Awnings are another old passive cooling method that have dropped off the general knowledge radar in modern times. If I ever get a house instead of a condo where I can't control the outside of the building, I'd install awnings but only know about why they were used because of another thread that mentioned them.

They don't teach these things in high school anymore.
