The study aims to propose a parametric simulation approach of outdoor wind environment to provide technical support and case reference for the optimal design of building outdoor wind environment.With the technologies of building environment information modeling,parametric programming and CFD simulation,we developed the parametric simulation model based on Grasshopper platform with OpenFoam and verified the accuracy of simulation through field measurement.The case study in cold region validated correctness and effectiveness of the proposed approach.The results showed that the parametric simulation method can significantly improve the accuracy and efficiency of outdoor wind environment simulation.The method is also suitable for the multi-scheme comparison process at the schematic design phase,which can provide the support for the decision making of optimal design and improve the quality of outdoor wind environment.
