A study on heating of residential buildings in the Yangtze River Valley of China

Yangtze River is China's densely populated and the most economically prosperous region. It's hot and humid in summer and cold in winter in this region. This area is considered as a non-heating region in winter, The residential building design usually does not consider the building heating requirements. The building envelope thermal performance is poor, and the indoor thermal environment quality is worse in the residential building in this region. In recent years, local experts and residents in the area have expressed strong willingness to building heating in winter. Consequently, on the basis of field investigation and field test, this paper has analyzed the choice of building heating mode from the aspects of local meteorological conditions, indoor environment status, local residents' living habits and residents' heating demand. Based on the results of the technological economic comparison of preliminary studies, suggestions on the suitable building heating mode were given in the Yangtze River Valley of China.
