If a building had no heat loss, there would be no need to supply heat to it. The determining factor in consumption is how much heat the building releases to the surrounding environment. Therefore, it is important to maintain room temperature – the lower it is, the smaller the delta, and the smaller the delta, the smaller the heat losses. Moreover, according to the heat exchange equation, this relationship is linear. If we reduce the room temperature at night and do not overheat the building during the day, then the daily heat loss is significantly reduced, which also determines savings in the operation of buildings.
