Some US apartments have shared heating. It’s pretty annoying because you have no control. I’ve had to keep my windows open in the winter because the heating was set too high.
In Russia, it's most likely an inverse of venue class. Malls, public venues, indoor markets, govt buildings all like to save on ventilation.
With slightly open windows, you're losing a bunch of heat for very little ventilation.
Many buildings in Denmark are supplied with heat (for room heating and hot water) by a municipal system, but each house or apartment can adjust the temperature of the room heating, with radiator valves or electronic thermostats.
We're charged based on how much heat we extract from the system.
