Research on the Ratio of Fixed Heating Charges to Total Heating Charges of Residential Buildings in Five Cities of North China

The ratio of public heating losses to total heating losses is fixed for a given building. The determination of this ratio is the basis for allocating heating charges fairly and reasonably, and is also the basis for determining the ratio of fixed heating charges to total heating charges. The changing rule of the ratio of public heating losses to total heating losses of 15 residential buildings in north China was researched under different conditions, such as different energy conservation performance, different usage and different layout etc, and drew some referable conclusions.
