Abstract：
In order to evaluate energy-saving performance of the composite steel residential building in cold region, an investigation on energy-saving behavior of composite steel residential buildings is carried out. Based on that, an on-site test on envelope of a typical composite steel residential building in cold region is conducted. The heat transfer coefficient of envelope and its actual energy consumption are calculated by use of the testing data; the influential factors on energy-saving performance and the parts that consumed the heating energy most are analyzed. The results indicate that the typical composite steel residential building can meet 50% energy-saving standard but could not the 65% standard; the heat bridge effect that existed in steel structure could decrease the overall energy-saving performance; the common used ALC wall panel has an evident deficiency in its thermal behavior. Finally the thermal design recommendations about composite steel residential buildings are proposed.
