Study On Exterior Space Form Of Commercial Pedestrian Street In Cold Area Based On Optimization Of Wind Environment

Commercial pedestrian street is an important part of urban space,and is closely related to crowd activities.In the transitional season with slightly cooler temperatures,the public is still willing to shop.Therefore,the study of the relationship between the outer space form of the pedestrian street and the wind environment,the adjustment of the morphological factors affecting the wind environment by passive design means to optimize the bad wind field and improve the comfort of the wind environment of the shoppers.The full text is divided into six parts.The first,second chapter of the paper is the basic research.First,through the background research and the literature review,we know the progress and shortcomings of the current research content: secondly,the qualitative and quantitative methods are used to study the relevant theoretical knowledge,and the wind is the commercial pedestrian street in the cold region during the crossing season.The most influential climate factors have been affected by the shoppers.The wind environment evaluation method of subjective and objective is summarized,and the standard of wind environment evaluation suitable for this article is found out,which provides the theoretical basis for the research and analysis of the third,fourth chapters.The third chapter first studies the influence of external space form elements on the wind environment,and determines the purpose of the investigation.Through the field investigation of the exterior space form and the fixed point measurement method of the commercial pedestrian street in the cold area,the wind environment problems existing in the pedestrian street are found and the reasons for the external space form are pushed back.SuchIn the fourth chapter,in view of the wind environment problems found in the survey,the PHOENICS software simulation method is used to combine qualitative and quantitative optimization strategies to solve the existing defects in the wind environment.This chapter is based on the climate of Luoyang,and the optimized design strategy is only applicable to Luoyang,but this software simulation aided space form design method can be extended to other cold areas with bad wind environment.The fifth chapter verifies the actual effect of these optimization strategies through practical projects,and judges the operability of the optimization strategy,and seeks the reasons for the design strategy of poor operability.Through the above data analysis,field survey summary,software simulation derivation and case verification,a set of optimization strategies for the optimization of the outdoor space wind environment for commercial pedestrian streets in cold areas are summarized.
