Abstract: Shanghai is situated within the Hot Summer and Cold Winter zone, where the requirement of improving the indoor thermal environment in winter grows rapidly. However, meanwhile we put effort in improving the indoor comfort, energy conservation should be considered for the constraints of total energy consumption. The building envelope plays important roles in heating energy use. In this paper, using building energy consumption simulation software DeST, different occupant behavior patterns and the life cycle energy consumption of external wall insulation were taken into account to help setting an appropriate standard of the heat transfer coefficient of building envelope in residential buildings. It was found that the energy saving potential of building envelope improvements could be significantly reduced under the “part-time, part-space” heating modes than “full-time, full-space” heating modes. Considering the life cycle energy consumption, it’s necessary to increase external insulation to a suitable thickness rather than blind increasing insulation since energy consumption of insulation materials manufacturing could not be ignored.
