| In recent years,more and more attention has been paid to green building,and relevant policies and regulations have been introduced constantly.Among them,wind environment is an important part of green building,is more and more concerned about the topic,wind environment can not only bring a healthy and comfortable living environment,but also reduce the use of energy consumption of indoor air conditioning to a certain extent.Suzhou,as a hot summer and cold winter area,has a unique climate to provide a good production environment,but the current design of the outdoor wind environment is not considered enough,there are many problems,the analysis of the dominant wind direction in summer and winter and the interpretation of climate zoning,only based on experience to simplify the design.Due to the lack of consideration of wind environment design in the older residential area,field testing found that there were problems such as large area vortex,windless area and excessive wind speed around windward buildings.Therefore,aiming at the current practical problems and aiming at improving the quality of residential wind environment,this paper analyzes the outdoor wind environment through CFD simulation and analysis technology and puts forward optimization strategies.Firstly,this paper collects the evaluation methods of wind environment at home and abroad,and makes the wind environment evaluation strategy suitable for this paper.Secondly,the CFD simulation analysis technology(Vent Software)and the field measurement results are mutually verified to verify the accuracy and feasibility of the simulation software.Thirdly,the status quo of Suzhou residential areas is investigated to understand the existing wind environment problems in Suzhou residential areas;Fourth,from the perspective of the spatial layout of residential areas,consider the impact on the wind environment and put forward targeted optimization strategies;Finally,combining theory with practice,the wind environment optimization practice is carried out for residential projects in Suzhou.The main innovations and achievements of this study are as follows: 1)After indepth study on the characteristics of outdoor wind environment of residential areas in Suzhou,the wind environment optimization strategy is proposed from the perspective of spatial layout of residential areas;2)On the basis of summarizing relevant studies at home and abroad,a wind environment assessment strategy suitable for this paper is formulated;3)Introduce CFD simulation analysis technology(Vent Software for Ventilation),introduce the operation process of the software in the actual project,and how to use the software simulation results to put forward the optimization strategy. |
