Ciao Thierry
I'm looking at 'weird' building values in Switzerland, and stumbled over https://www.openstreetmap.org/way/432786704 which you've added as `building=chauffage_à_distance`.
In OpenStreetMap we use (british) English tags for describing the data of the buildings.
In this case, I think that https://wiki.openstreetmap.org/wiki/Tag%3Autility%3Dheating would be more appropriate and I changed it accordingly in https://www.openstreetmap.org/changeset/171690047

Greetings from Bern,
