> mobile/portable ACs are allowed pretty much everywhere in Switzerland, I think. In Geneva even some mobile ACs, such as mobile split units, are banned without a permit https://www.ge.ch/rafraichir-climatiser-batiment/installation-climatisation-confort https://www.ge.ch/rafraichir-climatiser-batiment/installatio.... The only ones which are allowed are monoblock mobile ACs. Which is ridiculous given that they are the least efficient and consume way more energy than split mobile units or fixed ACs.
