Research on Energy-Saving Design Method of Green Building Based on BIM Technology

In view of the shortcomings of the traditional architectural design mode, such as high rework rate in the construction process and lack of collaborative design and intelligent information processing, a green building energy-saving design method based on BIM technology was proposed. Based on the comparative analysis of traditional computer-aided building design and BIM green building technology, the overall scheme of energy-saving design was constructed from the aspects of green building design principle, design preparation, and design concept. This paper expounded the connotation of energy-saving design elements from the aspects of modeling software selection, envelope energy-saving design, and lighting energy-saving design. Accordingly, the characteristics and process of building energy efficiency analysis based on BIM were proposed. Finally, the energy-saving effect evaluation method of green building based on BIM was given, and an example showed that the energy-saving design method of green building based on BIM proposed in this paper had good feasibility and effectiveness. The method proposed in this paper can provide a certain theoretical basis and application support for the application of BIM technology in the field of green building.
