@noiob @monorail Well, specifically the occupant, if they can control the temperature, must be able to warm their house to at least 20. you're allowed less, but if you're in an apartment without a thermostat it'll usually be set to 20-25C.
I like my temps a little seasonal but I'm not the only one living here
@noiob @monorail 20C is the minimum legal temperature for a rental here
