    Abstract：The energy-saving design for peripheral structure is very important to realize the energy saving of the prefabricated building. This paper studies the influence of exterior wall，roof，window type and window-wall ratio on the prefabricated building load. Take the example of a prefabricated building in Xi'an，build the basic model，conclude the reasonable window-wall ratio of the each orientation towards and the suitable insulation thickness，and optimize the energy-saving design of the outer envelope structure of the residential model. To study whether energy-saving design can meet the requirements of green building standards and provide some reference for the energy-saving design of the prefabricated house in cold area.
