Research On Green Architecture Theory And Methord In Public Underground Space Design

The development of underground space is the key to solve the problem of urban land shortage and traffic congestion.Building green underground space is an important measure to realize sustainable development.The city underground public space as the research object,based on the domestic situation of the development of underground space and analysis of the effect of underground space of green design elements,the article put forward the underground public space green design methods and evaluation system from three levels:site design,resource saving and the indoor environment design.Through domestic and foreign case studies,interdisciplinary research,quantitative simulation research,field measurement,expert questionnaires and other research methods,the design method of green underground public space is deeply studied and discussed innovatively.The article can be divided into five parts.The first part is the first chapter and the second chapter.It introduces the theories and concepts related to the green underground space from the theoretical level.The second part is the third chapter of the article,and analyzes the factors that affect the green design of the underground space.The third part is the fourth chapter and the fifth chapter of the article,and puts forward the green design method and key technology of the underground space.The fourth part is the sixth chapter of the article.It is the application and evaluation research of the green design method of public underground space in practice.The fifth part is the seventh chapter of the article,which is the conclusion of the article.It mainly summarizes the achievements of the research and prospects for the application of green design in the future underground space.The innovative conclusions of this article are as follows:1.The design of green underground public space should fully consider the combination of its spatial form,three-dimensional development and human comfortThis paper defines the concept of underground public space.And build a green underground public space design theory system according to the combination of building space theory,human needs theory and compact city theory.Combined with the particularity of underground space,through the study of the relevant basic theory,it is concluded that the design of green underground public space should take full consideration of its space form combination,three-dimensional development and human comfort experience.2.Analysis of the factors affecting the green design of underground spaceAlthough some factors affecting the green design of the buildings will affect the greendesign of the underground space,the influence factors of the green design of the underground space are not exactly the same as the ground buildings because of the particularity of the underground space.The article analyzes the factors that influence the green design of underground space from three aspects,including site factors,energy consumption factors and indoor environmental factors,and provides a basis for the design method and evaluation system of underground space.3.Based on the analysis of the factors of influence,the green design method and key technology of underground public space are put forwardBased on the analysis of the factors that influence the green design of underground space,this paper puts forward the green design method of underground public space from three aspects: site design,energy saving design and indoor environmental design.The analysis shows that factors such as factors in the site,terrain conditions and space utilization efficiency will affect the site design of underground space.Under different terrain conditions,the design methods of underground space are different,and local conditions are beneficial to the efficient use of land.The integration and transformation of the function of underground space also helps to improve the vitality of the underground space.In addition,the development of underground space in some historical cities is conducive to improving the efficiency of land use,but the development of underground space should be protect the historical context of the city at the same time.At the level of energy saving design,the author proposes that the different types of underground space layout will cause the different area of the enclosure structure,and then influence the thermal environment inside the underground space.By using the control variable method,the quantitative simulation of different forms of underground space is carried out by Ecotect software.It is concluded that the narrow space will increase the structure area of the underground space and then increase the energy consumption of the underground space.On this basis,the author proposes that the design of underground space should avoid the narrow space as long as possible and reduce the area of the enclosure structure.At the level of environmental creation,the author puts forward different ways to create environment for different functional spaces.The design of the cohesive space environment should be closed and guided,and the open space environment should be coordinated with the surrounding environment.The interior environment design also brings comfortable and comfortable experience to people from the light environment,the sound environment,thedamp and hot environment and the interior landscape.Taking Tianfu Square and Chunxi Road area of Chengdu as an example,the author makes field measurement and quantitative analysis of the internal environment of Chengdu underground public space,and provides optimized measures for the green design of Chengdu underground public space according to the green design method mentioned above.In addition,the author puts forward the key technologies of underground space design from three aspects:active technology,passive technology and renewable energy utilization.For example,natural light and wind are introduced into the underground through the design of skylight and sunken courtyards,which is beneficial to saving energy and providing a comfortable environment for people;The purpose of saving energy is to use energy saving lamps,intelligent air conditioning systems and new energy sources,etc.In the natural lighting design part,the author uses Ecotect software to conduct quantitative research on two ways of skylight lighting and courtyard lighting,and discusses the influence of skylight shape,material and courtyard depth on the natural lighting of underground public space.4.Construction of green underground public space evaluation system based on the analysis of influential factorsBased on the analysis of the factors influencing the green design of underground space,this paper puts forward the evaluation index of green design of underground public space from three levels: site design,energy saving design and indoor environment creation,and builds corresponding evaluation system.This paper calculates and determines the weight of each influence index by analytic hierarchy process.On this basis,this paper evaluates the specific project through the comprehensive fuzzy evaluation method.In a word,although the application of green concept in the design of underground space in our country started late,it develops very quickly,and has great potential and advantages.To realize the diversified and systematic development of the green concept in the design of underground space is the necessary measure for China to build an ecological green underground space and realize sustainable development.This paper summarizes the green design method of underground public space from the urban design and architectural design level,and green design evaluation system is constructed of underground space.At the same time,the paper taking Tianfu Square in Chengdu as an example,applies and verifies the evaluation system,which is of guiding significance to the green design and evaluation of underground space.
