—In hot summer and cold winter zone of China, the intermittent and compartmental heating method of air conditioning is widely adopted. The intermittent heating method makes the heat storage in walls become the main way for heat dissipation. The compartmental heating method results in a large amount of heat loss not only in exterior walls, but also in interior walls. Based on this heating method, a series of experiments were conducted in Shaoxing, a typical city in the hot summer and cold winter zone. The results showed that, internal insulating method for exterior wall could save more energy than external insulating method by reducing the wall heat storage amount. Besides, both the exterior walls and interior walls should be insulated as the heat loss in interior walls accounts for a large proportion of the total heating load and whether the adjacent room heating or not has little effect on reducing it.
