In the process of urban development, a large number of industrial heritages are in needs of being renovated as a result of the failure of meeting new needs. However, there has not yet formed an innovative and sustainable update design process. Based on the analysis of the problems existing in the renewal and reconstruction of industrial heritages, this paper, hereinafter, will establish an innovative design system by way of introducing extenics and BIM and combining the formalized and innovative advantages of extenics and the characteristics of BIM: information storage, processing and visual programming. In combination with the design of practical cases, this essay conducted the system, to verify its rationality and effectiveness; to discover limitations in its operation, and as the ultimate purpose, to propose directions for further research.
