In recent years, with the development of Chinese construction industry and continuous pursuit of green and sustainable development goals, the designers have gradually adopted BIM technology to analyze building energy conservation. On the basis of summarizing the concept of green BIM idea and corresponding analysis software, this paper analyzes the green energy saving of multi-storey buildings through practical case study by using green building Siwell software. Firstly, the software is used to read the building drawings, and then to select appropriate building materials, as well as to simulate and optimize the design of the energy saving, daylighting and sunshine of the building according to the corresponding technical standards. By using the software, it can be intuitively shown the impact of basic building data, energy loss and natural conditions on the building. The research results of this paper can provide design basis and reference standards for similar schemes in this region, and fully demonstrate the advantages and broad prospects of BIM technology.

With the present rapid development of informatization in the construction industry, the BIM technology is acting an important role in promoting the upgrading of technology in the construction field, which brings great changes in the way of talent cultivation in the application-oriented colleges at the same time. Although the first-class universities in China already have made great progress and acted as demonstration roles in the development of BIM technology and talent training, the application-oriented colleges are still trapped and faced with many problems including shortage of teachers and lack of facilities. Based on the summarization of the present development status of BIM technology, this paper proposes reform measures and suggestions from the aspects of cultivating autonomous learning ability of BIM, setting course group on BIM technology application, BIM competition, in-depth cooperation between school and enterprise, and establishing BIM question library, which can provide reference for the development of BIM technology and talent cultivation in the application-oriented colleges in China.
