Abstract

The purpose of this research is to investigate built building envelope renovation methods. Earlier studies on built building renovation have shown that the significant influence of using built building instead of the new building in terms of the energy crisis. However, these have not yet compared various renovation methods for building surface. Therefore, this study classified several reconstruction means into three types and evaluated their performances under three indicators: 1) construction; 2) material; 3) impact on original building appearance. The result shows that the integrated system of insulation and decoration is the best, and the method of additional components is the worst for building enclosure renovation.
