My wife and I live in Hungary. Every so often we visit Phoenix, AZ in the summer to see family. (My wife is a teacher so it makes sense to go in summer) and the hardest thing for us to do when we go out to eat is finding a restaurant that has seating where we are not freezing cold. It will be 40+ outside and 20 inside.

Yeah, regrettably, the American practice seems to be to overchill in the summer and overheat in the winter. This is also done in the home to the point that people will wear shorts and tshirt indoors in the winter and warmer in the summer (blankets while watching TV for example). Also office buildings suffer from the same problem. Women usually complain the most about it being too cold (men are more likely to wear suits and generate more great I believe).

That is probably partly explained by (at least in older houses without reflective insulation) low radiant heat from outside in the winter, and high radiant heat from outside in summer.

And different humidity explains it some too, even though AC lowers humidity, indoor humidity is still much lower in winter.

I've joked for years that the hotter the place in the US, the colder they keep their AC in the summer.
