Except that isolations keeps warmth in, or out in the winter, but not both. Not that simple.
But you’re right about cities and AC, I was in Madrid in august last year, jesus it was hot. So hot it was probably dangerous, I wonder how much was caused by ubiquitous AC.
I beg to differ. A good insulation insulates two systems from another. In this case the air outside and the air inside. So with a good insulation you don’t need as much heating when it is cold outside and cooling when it is hot outside.
