Most french housing doesn’t have AC to begin with. My very recent apartment has none, the one I’ll be moving to (which is currently being built) won’t either. It’s only built under the notion that energy is a winter issue, and designed to keep the heat in.

The start of the heat wave was uneventful for me, but I now restrict my day in a tiny square in front of the portable AC (so much for saving energy by not designing the building with AC in mind…)
