In order to study building BIM technology PKIM energy building engineering software system, firstly, the building collaborative platform based on BIM technology and PKPM professional software BIM technology application is constructed. Then, it introduces that PKPM connects all aspects of construction projects through the core 3D data model and takes the lead in realizing the BIM concept of information datalization, data modeling, and model generalization, thus realizing the full utilization of building model data in the whole life cycle. Finally, this paper introduces the seismic analysis method of structure based on BIM platform, taking a complex building with a transfer storey structure as an example. The experiment shows that the BIM model can be used to analyze and calculate the building performance, such as sunshine, energy consumption, daylighting, and evacuation of people, and complete the green building design. The BIM model can also generate professional construction drawings of buildings, structures, and equipment.
