Research On The Green Renovation Design Strategies Of Existing Industrial Zones In Guangzhou City From The Perspective Of Passive Design

With the rapid development of urbanization and the adjustment of industrial structure,industries in the urban city have been moved out one after another,leaving behind numerous abandoned industrial zones.In order to solve the existing problem of land resources shortage in urban renewal,people have studied the problem of rebuilding and reusing the existing urban industrial zones.However,due to the lack of consideration of environment and energy saving,part of the stock space has not been effectively reused,and hence facing the dilemma of reformation again.Combining the transformation of existing urban industrial zones with the sustainable building design concept could provide an innovative solution for the problem.Passive design strategies,is an important approach to realize green buildings which emphasizes on maximizing the self-adjusting ability of the building through the starting of the main body of architectural design.Applying the concept of passive design to the transformation of existing urban industrial zones can not only expand its transformation methods and improve its overall quality,but also acts as an critical means to promote the sustainable development of the project.This paper takes existing industrial zones of Guangzhou city as the research object,adopts the architectural bioclimatic design method,combined with weather tool,PHOENICS and other analysis software,to study the green renovation design strategy of the existing industrial zone under the passive design concept.First of all,based on the research of passive design theory,it explores its combined application with the transformation of existing urban industrial zones,builds a working mode for the transformation of existing urban industrial zones under the concept of passive design,and points out the corresponding method paths for each link.Secondly,through the development process of Guangzhou’s industrialization,its distribution characteristics,spatial types,and the status quo of transformation,it explores the demands and characteristics of the transformation of its industrial zones,combining the characteristics of Guangzhou’s climate and using the weather tool to propose a passive strategy suitable for guiding the transformation of Guangzhou’s existing urban industrial zones.Heat insulation and cooling,natural ventilation,natural lighting,building shading and evaporative cooling,and learn from traditional building methods to adapt to the climate to enrich the regional practice of passive design in Guangzhou.Finally,from the planning and construction level,the design strategy for the green reconstruction and reuse of Guangzhou’s existing industrial zones is summarized and put forward.By matching the relevant characteristics of the existing urban industrial zone and the transformation design process,this article will pass the passive design thinking from the overall spatial layout and environment and the building monomer levels into the existing urban industrial zone transformation design strategy in Guangzhou.From the overall space and environmental layout level,the group layout transformation design strategy that blends climate and terrain,the orientation transformation design strategy that conforms to the wind and heat resources,the spacing transformation design strategy using the cold lane effect,and the improvement of the underlying surface material and the optimization of the landscape system are proposed.The design strategy of site environment renovation;from the single building level,the design strategy of building form renovation based on natural ventilation,shading and heat insulation,and natural lighting is proposed,and the functional space renovation design strategy of reasonable division of tall spaces and optimized configuration of function transformation is used to make use of the atrium,grey space and structures adjust the wind,light,and thermal environment of the buffer space and the transformation design strategy of the structure,improve the energy-saving performance of exterior walls,doors and windows,roofing,and configure the shading components of the envelope structure transformation design strategy,as well as the vertical greening and roofing of the facade greening design strategy for three-dimensional greening transformation.
