Study On Outdoor Space Wind Environment Of Urban Complex In The Cold Region Of Northeast China

With the rapid development of China's economy,more and more complex buildings are springing up in cities.As a group type of architecture,we should not only consider the micro environment of the building itself,but also consider the relationship and influence among the buildings.In recent years,urban complex buildings have appeared in the severe cold regions in Northeast China.The harsh climate environment in winter has put forward a new test for the designers.How to improve the thermal comfort of the outer space in this area and improve the utilization of outdoor space becomes the difficulty of the complex design.In this paper,the external spatial wind environment of urban complex in cold region is taken as the research object.The external space types,such as entrance,street and square in different layout forms,are simulated and analyzed in order to improve the micro environment of the complex outer space and provide better living and living environment for the users of the urban complex.This article is divided into three parts.The first part mainly introduces the background of the topic selection,the current research situation at home and abroad,the purpose and significance of the research,the research methods and contents.In the second part,a series of basic research on the existing urban complex in the cold region of Northeast China is carried out.On this basis,the field data of the typical urban complex in Shenyang is measured and the characteristics of the stroke environment of the urban complex are preliminarily analyzed.Then,on the basis of the validation of the effectiveness of the simulation software ENVI-met,four typical cases in the existing urban complex in Shenyang(the layout form "Hui","L" and compound)are simulated in different seasons(summer,transition season and winter),and the following optimization strategy is proposed for research basis.The third part from the wind direction angle,multi high-rise building combination,building space,layout and greening measures five aspects of the analysis of the wind environment of the group building,summed up the wind environment optimization measures.On this basis,the effectiveness of wind environment optimization measures for existing urban complex is verified,and suggestions for future urban complex design are put forward.This paper uses the methods of measurement,simulation and optimization to study the wind environment of urban complex in severe cold areas.It is hoped that it can not only provide effective measures for the improvement of the wind environment for the existing urban complex,but also provide a better design scheme for the urban complex in the severe cold areas.
