Research On The Design Strategy Of Climate Adaptive Buildings In Nanning

Under the background of global carbon neutrality,green,low-carbon and sustainable architecture are the inevitable trends of current building development.Over-reliance on industrial equipment not only has a negative impact on the natural ecology,but also disconnects the development of architectural technology with the regional climate environment,which brings impact to the regionalism of architecture.Therefore,the key to solve the problem of disconnection between building technology and regional climate environment is to adopt design strategy of climate adaptive architecture according to local conditions.The theoretical research on climate adaptive architecture creation in Nanning city is still in the initial stage,and there is a lack of systematic theoretical research results for architects to refer to in practice,which affects the regional expression of Nanning local architecture to a certain extent.On the basis of analyzing the case of climate adaptive architecture in Nanning and summarizing the practical experience of local architecture creation in Nanning,this paper explores the architectural design strategy that is compatible with the humid and hot basin climate and construction level in Nanning.This paper is mainly divided into five parts: introduction,theoretical research,design strategy research,practical case analysis,conclusion and prospect.Firstly,the first chapter introduces the research theme of climate adaptive architecture design strategy based on the discussion of globalization and regionalism,building technology and climate environment.Through the analysis of the topography,climate conditions and social and economic conditions of Nanning,it is concluded that Nanning has the climate characteristics of subtropical basin with high temperature,high humidity and less wind,and the regional characteristics of poor construction conditions.Therefore,the paper proposes that the design strategy should be adapted to local conditions to control the construction cost and achieve the goal of moderately comfortable buildings.Secondly,by combing and analyzing the development process of climate adaptive buildings in Nanning in the second chapter,this paper summarizes the spatial prototype of climate adaptive buildings in Nanning,and puts forward that self-shading and heat insulation,ventilation and heat dissipation,and environmental cooling are the key technical measures to achieve building climate adaptation.Drawing on the systematic theory of traditional environmental philosophy,this paper proposes a systematic thinking method to deal with the relationship between buildings and the climate factors of wind,light and water in the environment,and an architectural design strategy that actively responds to the humid and hot climate with little wind of Nanning city from different levels of site design,single building space design and interface construction design.Then,according to the design workflow from the whole to the part,this paper analyzes the principle of building design strategy to adapt to climate,combined with engineering practice cases.The third chapter summarizes the site and environment strategies that are conducive to the climate adaptation of buildings in Nanning.It is proposed to optimize the ventilation environment of the site and shield the sun by using the terrain height difference,adjusting the building orientation and reasonably arranging the vegetation,and to use the site water system and vegetation transpiration to achieve the site cooling.The fourth chapter summarizes the design strategies of individual buildings that adapt to the climate of Nanning.It is proposed to improve the natural ventilation of the building by reducing the windward area of the building,controlling the depth of the building,adopting open ground-floor space and organizing the connected cavity to funnel wind;realize the self-shading of the building by increasing the body overhang,setting up the buffer veranda and adopting the eaves gallery on the ground floor;reduce the temperature of individual buildings by organizing evaporation and heat dissipation of reclaimed water,using groundwater for fresh air precooling.The fifth chapter summarizes the design strategy of exterior enclosure interface of building that adapt to the climate of Nanning.It is proposed to improve the wind guiding capacity of exterior enclosure interface of building by reasonably setting the air vent and air guide components;Adopt facade and roof shading components,three-dimensional greening and other measures for building shading;Use water storage roof,flowing water roof or evaporative cooling facade to realize heat dissipation and cooling of buildings.The sixth chapter analyzes the three projects of Southern Chess playing Building,Southland Village-Museum of Farmhouse in Science and Technology and Guangxi Nanning Ecological environment Exhibition Hall,and discusses the application of climate adaptive architectural design strategy in Nanning.Finally,the seventh chapter summarizes the research results of this paper,analyzes the shortcomings of this study and puts forward the prospects for the future.
