This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

I had a crazy thought. What if you used depressurization to cool interiors?
Not as in depressurize the room and potentially kill the people inside, but in a way similar to soundproofing where you create an airtight gap in your walls, depressurize it to create a partial vacuum and effectively restrict both heat and sound transfer. That way it would be much easier to control internal temperature.
The only two problems I can see with it is expense (pumping air out of the gaps between your walls could be pricey), and the potential of explosive repressurization if something were to break the wall.
Wall isolation is pretty fine as it is, main weaknesses are windows and thermal bridging.
We still have the issue that a perfectly isolated house will need to lose the heat created by humans and electric systems, so actual cooling is required.
