The BIM technology is a new information technology and one of the most important ways to achieve the sustainable development and informatization for the construction industry.However, lacking of a unified BIM data storage and transmission standards becomes a major obstacle to development.The IFC and the gbXML are both important BIM standards for solving the interoperability issues between BIM modeling software and green building analysis software.According to the analysis of the green building information model for IFC and gbXML, this paper develops a green building performance analysis process based on the IFC and gbXML, explores the way to share information between different software, and also provides advices to solve the information island issue for BIM-based information exchange.
