The Research Of Parameter Design Method For Architecture Morphology Based On The Wind Environment

With the rapid process of urbanization,many environmental consequences follow from the growth of severe ventilation,increase pollution,leading towards the severe haze and urban heat island.Based on plenty of the research result,optimizing the wind environment of building complex is a effective way to deal with these environmental consequences.While the operational strategies of architecture design and urban design is needed.This paper aims to explore the correlation between the wind environment and architecture morphology,and provide a systematical design strategy for building morphology based on the wind environment.The design basis and method is proposed to improve the wind environment.The paper is organized as follows.Firstly,reviewing and analyzing the literature resources both in home and overseas,which are mainly about the regulations of building morphology,the layout of building complex,building forms and the wind environment,aims to confirm the research direction of the architecture morphology and the wind environment.Following,it proposes the evaluation factors of the wind environment of building complex and those of the architecture forms.In the architecture morphology,it claims the parameters of building forms,the layout of building aggregation,and building form itself.In the wind environment aspect,according to the wind speed and wind-induced vibrating comfort,it proposed a evaluation system of wind environment of building complex,analyzing the features of wind field.In addition,it describes a plenty of case studies,providing the method of rounding edges,curve surfaces,cutting blocks,convexity the upwind side,structuring and ordering boxes,back sets of architectures,inclining architectures,cutting holes on the fa?ade and dispersing building forms to optimizing the architecture forms.Grasshopper is used to support the new building form automatically.Furthermore,it gives the evidence to the new design strategy by using the automatic program and testing it by CFD model,analyzing the impact of the wind environment quantitatively.Moreover,this paper research the case in Dalian city.In terms of the system of LCZ,the locations are confirmed at Xi’an Lu business blocks,train station business blocks,andZhongshan District of office blocks in which proceed the CFD simulations.According to the problem of wind environment,choosing automatic program to optimize the building.Finally,proceeding the CFD simulations with the newly changing form provide the strong evidence for the effective design strantegies.Overall,based on the previous theory of wind environment and building morphology and the parameterization technology,the paper claims the future of the the parameter method of architecture morphology.Dealing with the severe problem of haze and urban heat island by certain strategy is the main point proposed in this paper.
