Research on Forward Design of Green Office Building Based on BIM

With the implementation of the dual carbon strategy, we will promote the development of office green building design and build a new mechanism for its development based on the principle of green ecological sustainability and under the guidance of BIM’s multiple collaborative concept. In the full cycle design stage of the building, the digital simulation of the green performance of office buildings and the structural overrun design are mainly used to optimize the architectural design, so as to avoid the phenomenon that the defects in the architectural scheme stage lead to the later use of technology stacking to make up for its “congenital deficiency”. In the Yangtze River Delta port front headquarters project of Shanghai runYou technology, the BIM positive design process is proposed from the perspective of architect responsibility system, and then the BIM optimization model is constructed with green performance as the variable, integration and environmental simulation analysis and structural overrun calculation, and energy consumption and comfort as the goal. The research results help to enhance the low-carbon design performance of buildings, It provides theoretical and practical basis for design decision.
