What restrictions are there on AC?
The EU's F-Gas Regulation creates significant restrictions on refrigerants used in air conditioning
There's significant red tape when installing AC due to building regulations
90% of US homes have AC while only 20% of European homes have it, I don't think that's by accident.
Fun fact, some EU countries even have laws telling you how much you can open your windows! In the UK, there is a law that in any public building, windows must not open more than 100mm (about 4 inches).
And 27C is a completely normal temperature. When it's 35C outside, you're better off with a minimised thermal shock with a small difference, instead of going at it the US South or Dubai style where inside it's 18C, so all everyone does is move from one air conditioned place to another (home to car to office to car to mall to home).
Your mentions PUBLIC building policies are irrelevant
So?
