Ratio of public heating charges to total heating charges for residential buildings in five cities of north China

Reasonable determination of the ratio of public heat loss to total heat loss is the basis for allocating heating charges fairly, and the basis for determining the ratio of fixed heating charges to total heating charges. Researches the changing rule of the ratio of public heat loss to total heat loss for fifteen residential buildings in north China under different conditions, such as different energy conservation performance, different usage and different layout, etc. The results show that the ratios are notably diverse under different climate and different energy conservation performance, and the ratio for buildings with energy saving by 30% is close to that for buildings with energy saving by 50%.
