An analysis is performed for a typical residential living space with intermittent energy use in a hot summer and cold winter zone. Analysis performed in this study include a dynamic, three dimensional heat transfer model that examine the intermittent heating and cooling loads in a typical living space in Shanghai. Different wall structures (non-insulation structure, exterior insulation structure, or interior insulation structure) can have different influences on the energy efficiency in buildings. Results conclude that the interior insulation structure provides the largest reduction of energy consumption in buildings when compared to the other wall structures in a hot summer and cold winter zone. For the interior insulation structure in this study, the typical thermal insulation thickness is 0.03 m.
