What percentage of US buildings would you say have air conditioning? The amount of UK homes that have AC is basically 0. Although I guess most commercial buildings would have it. I wonder if this is because UK homes are mainly brick, would that make a difference? Absolute max temp here in summer is 40 degrees C for 1 or 2 days and 30 degrees is pretty rare on most days in summer. When I saw the title I'd assumed this was about rainfall and guttering, which is something we do know about in the UK!
