Here in the UK we don’t generally use A/C not because of health concerns but because there’s only about three or four weeks of the year we’d actually need it so in practice fans and complaining heavily during those three or four weeks does just fine. Our climate is generally damp, grey, and mild; the summers don’t get very hot and the winters don’t get very cold. This might change with climate change though, I suspect in the future we’ll need better cooling and better heating if the jet stream gets interfered with. We’ll also need better drainage but there’s no shortage of scummy housing developers putting their underbuilt and overpriced shoeboxes on flood plains.
