Abstract: With the rapid growing of green buildings in China, it is very important to take the operation and the maintenance of these buildings. However, due to the isomerism and diversity of current information platforms, the actual performance of some projects failed to meet the design expectations. BIM technology has the characteristics of visualization and information integration, which has capabilities to solve these problems. According to the actual demands, this paperhas proposed an idea of multi-source heterogeneous data based on a standard BIMS database, which can provide references for future system architecture of green building operation and maintenance platforms.
