Abstract: Green building and building energy conservation are important factors in the sustainable
development of the construction industry. However, BIM (building information modeling) has a wide
range of software and various data standards, and loss of information is frequent during the data
transfer. Thus solving the “information island” problem and the interoperability issues between
different software is the key for BIM application. This paper first analyzes the green building
framework based on IFC (industrial foundation classes) and gbXML standards, and chooses BIM
modeling software ArchiCAD and green building performance analysis software Ecotec to test and
evaluate the interoperability, so as to identify the problems of BIM data standards and BIM tools in
the process of BIM data transfer. The paper provides specific improvement methods and suggestions
to solve the problems, including reducing the information redundancy for IFC formats, increasing the
support to green building area in the IFC standard, and improving the accuracy for the definition of
green building information in the IFC resource layer.
