I'm very much in the same boat as you. It's a pet peeve of mine that every building now seems to have a completely different climate to the outside world. I'll never get how people don't understand - or don't want to go through - the process of acclimatisation. If it's 30C outside, having the AC on at 20C all day is of course going to make 30C seem unbearably hot! As a student I lived in the North of England in Newcastle, where temperatures averaged around 0C in the winter and because we couldn't afford heating the house was often around -2C. I would still walk around in t-shirt and shorts without problem. I later moved in with a group of girls who had the heating knocked up to 25C all year round, and within a week stepping out of the door felt like jumping into an ice bath. Rapid temperature change mess up so many of our bodily processes that I'm amazed it's discussed so little. If I don't sleep with a window wide open I know I'll struggle to get even a single cycle of REM sleep, and almost all of the people I've convinced to try sleeping with a window open and the heating off have told me their sleep improved ten-fold after a couple of weeks.
