>In most reasonably managed apartment buildings what you did is forbidden because it means your neighbors just have to heat more since their walls will leak heat to you. In your idea of "reasonably managed" buildings, everyone is forced to keep the heat on way too high, so a bunch of people open their windows wide open to bring in cool air, resulting in a massive and ridiculous waste of energy. The problem is that some moron in charge of the thermostat wants it much hotter (in the winter) or colder (in the summer) than ecologically- and economically-minded people who prefer to save energy. There's never any kind of democratic system for setting the thermostat, plus different people have different comfort levels. If the neighbors don't like high utility bills, then they should stop using so much energy. There's nothing requiring them to keep it as warm as they do: it's not hard to put on some warm underwear.
