In the past, because of the f act that the buildings here were not planned to be heated in winter, there was nearly no district heating systems here. And as a result, the indoor air thermal and humidity environment here was the most inferior in China. However, with th e improvement of people’s lives and needs of comfort, more and more buildings are designed with heating systems now. The characteristics of climate here decide that th e heating mode here is small-scale district heating or home-scale heating systems. Confirming the most suitable heating metering mode on the basis of climate characteristics and people’s customs here plays a significant role for the energy conservation of buildings here. Currently, there are many he
