Good luck convincing old building protection pressure groups about it (yes, around here these people are real and have power). Not to mention the bureau actually in charge of landmark protection (in some areas everything is a landmark).

Portable AC units are pretty universally allowed where I live in Austria. The mini split units are also allowed, but I've seen some folks get letters about these specifically.

Unless you have split mobile AC portable units are very inefficient.

Tbh even in old buildings it might be possible to reabilitate old chimneys for AC (or rather heat pumps).
