I stayed in a house in Rome that kept out the fierce summer heat, because of thick walls. AC would be redundant. In other places, like Hong Kong, the thin walls of the apartments need AC to remain liveable in summer. I've read about the lack of shade in many built environments. Seen TV shows where someone builds floor-to-ceiling panoramic windows in a location that would be below 0 for much of the year. Unsustainable construction drives AC use and greenhouse gas emission that makes the problem worse.
