Heating/cooling/power load characteristics in china’s severe cold region

This paper deals with typical residential buildings constructed according to the national energy-efficiency standard in China’s severe cold region. Dynamic heating/cooling loads of residential building models were simulated via a factorial experiment. The electricity consumption of residential buildings was investigated, and the characteristics of the power load were analyzed statistically. The results show the cooling/heating/power load indexes of S–N- and E–W-oriented multi-story residential buildings in China’s severe cold region. In addition, notable factors of heating/cooling load were obtained via a factorial experiment analysis. Besides, simplified formulae were obtained, which can be used to calculate heating/cooling load indexes for multi-story residential buildings in China’s severe cold region. Furthermore, the heating/cooling/power load index can be applied to calculate the maximum load of a residential building in planning and design stage. According to the maximum load, equipment capacity can be determined. And the key variables can be used in building energy-saving design.
