this paper introduces An outline of the HS-EPS module building energy saving system of reinforced concrete core columns, its composition, applications and the technical specifications. A comprehensive analysis of the system on technical features and advantages of the system, such as building energy conservation, seismic, industrialization and standardization is introduced. In recent years this system has been applied in many projects in various parts of China including the the application and promotion in the post-disaster reconstruction projects. The ong-term study, extensive analysis and application of this system have proved its high performance, reliable quality and high application value.
