In fact it's even more of a problem for new buildings. For old buildings you can complain that the building is unsafe to live in without AC, but new buildings are required to be livable (<26C) without air conditioning, so it's very easy to get a blanket rejection for this very reason alone.

Of course even though new buildings should be livable without AC, this is not true in practice. I live in a new building and right now I have 33C indoors inside my apartment. But some bureaucrat signed that it's 26C certified so who am I to complain!
