Abstract:

Energy-saving buildings have been constructed based on the German energy-saving passive building codes in China these years. However, the energy-saving system of passive building may not suitable for the hot-in-summer and cold-in-winter district in China. In this regard, researches and applications of the external heat-preservation technique using building walls is presented. Furthermore, the comparison between the simulation of energy-saving and pertinent data from engineering application is also shown in this paper. The investigations reveal that it is not advisable to adopt the existing passive building for the hot-in-summer and cold-in-winter area in China based on the German energy-saving codes using external walls. The study suggests that heat transfer index of the energy-saving buildings needs more investigations according to different climate divisions.
