Abstract：
In this paper, a type of prefabricated house was introduced. The retaining wall consists of reinforced concrete hanging plate, concrete column with claw，XPS board，internal plate，and inner filling mineral wool board. Load-bearing structure was light steel. Floor use reinforced concrete composite slabs. Light tile roof for insulation. By the thermal performance test for this house, heat-insulating property achieves 65% energy-saving requirements in China. It has many good characteristics, such as low-carbon, environmental, energy-saving, economic, sturdy and durable features.
