Abstract—The steel frame-reinforced concrete core wall structure is a typical composite structure, which has been applied to residential buildings for its excellent seismic behavior. In order to evaluate the energy consumption of existing residential buildings with composite structures, an on-site test on envelope of a typical composite steel residential building in cold region is performed; the heat transfer coefficient K of envelope and its actual energy consumption are calculated and analyzed by use of the testing data. Based on that, a simplified computer model is established and verified. Parameter analyses are carried out on two main influential factors. The results indicate that the building envelope has good heat storage property and it could keep indoor thermal stability; the steel frames and windows have heat bridge effects;the tested building only meet requirements of energy-saving 50%-standard, instead of 65%-standard; the traditional calculation method for energy consumption overestimates the energy consumption of buildings; the most effective way to reduce heating consumption is to improve thermal performances of external walls; the thickness of insulation layers should be confined in an appropriate range. Finally the thermal design recommendations for composite steel residential buildings are proposed.

Index Terms—Computer simulation, energy conservation, thermal insulation, residential building, test, energy consumption, building envelopes.
