Research On The Natural Lightscape Strategy Of Expo Architecture

The expo building is a concentrated expression of the long cultural history of a nation.At present,the construction of the expo building in my country is in a period of vigorous development in terms of type and quantity.In the exhibition building,the light environment has always been the focus of research.With the development of spiritual civilization,people’s requirements for the light environment of the exhibition building not only satisfy the display function,but also gradually pay attention to the visual experience of the light environment.Therefore,how to shape the artistry of the light environment in the exhibition building and enhance the user’s visual experience is an urgent research.The concept of lightscape provides new ideas for the design of the exhibition building.Natural lightscape can give a changing environment and rich visual effects.It is a powerful means to enhance the space experience of the exhibition building and enhance the artistry of the light environment.First of all,based on the concept of "Scenery",this article takes the expo architectural space as the research object,using literature research,field investigation,questionnaire survey and other research methods.First of all,this article analyzes the type characteristics,space composition and combination mode of the exhibition building,natural light design requirements,and the composition and influencing factors of the scenery through the research on the related literature of the exhibition building and the scene,summarizes the function of the scene,and proposes this article The research elements and analysis methods of the situation.Secondly,a field investigation was carried out on the architectural scene examples of the expo from the three aspects of space environment,scene performance,and subjective experience of users.Combined with the survey results,the scene performance characteristics and design points that meet the subjective needs of users were explored.Thirdly,it further summarizes the principles and strategies of natural landscape construction in the exhibition building.Finally,taking the lighting optimization design of the Changsheng Hall Phase 2 of Luyeyuan Stone Carving Museum as an example,the researched lighting construction principles and strategies are applied and demonstrated,in order to provide a certain reference for the lighting construction in the architectural design of the expo.Based on the ideas of "discovering problems","analyzing problems",and "solving problems",this article expands the discussion from the following six chapters:The first chapter is the introduction,expounding the research background,research purpose and significance,research object and concept definition,and the current situation of related research at home and abroad.It explains the necessity of this research,and clarifies the research content and research methods of this article.The second chapter is to analyze the basic theories of expo architecture and scenery,and put forward the research elements of this article,and summarize the functions and analysis methods of scenery.First,it elaborates on the types and characteristics of the exhibition building,space composition and combination mode,and natural light design requirements.Then it sorted out the three major components and influencing factors of "light","people" and "space environment" of Guangjing,and selected the research elements of this article according to the principle of significance and practicality.Finally,the functional role of the scene is summarized,and a quantitative and quantitative analysis method is proposed.Laid the foundation for the case study in Chapter 3.The third chapter builds the research system of this article based on the background results of the previous chapter and analyzes the research results.The first part is to design the research plan,clarify the purpose of the research,surveying and mapping,questionnaires,optical physical quantity measurement and other research methods and research content.Three museums,namely,the Bell Museum of the Cultural Revolution,the Luyeyuan Stone Carving Museum,and the Indomitable Prisoners of War Museum,are selected as in-depth research objects..The second part is the detailed research results,explaining the spatial combination of the research objects,the characteristics of the space environment,and the objective performance of the scenery.It also evaluates the objective performance of the scenery from the perspectives of light perception and light satisfaction,and explores meeting the subjective needs of users.The performance characteristics and design points of the scene.It provides a reference basis for the principles and strategies of building landscape construction for the fourth chapter.The fourth chapter is based on the case study results of the previous chapter,combined with previous literature and case studies,and put forward the principles and design strategies for the construction of the expo architecture.Put forward the four principles of "systematic","interesting","artistic" and "functional".Three major design strategies are proposed,including the shape design strategies of "concave and convex shape","dislocation of shape" and "hollow out shape";"lighting opening cut light","light control interface optimization light",and "light-bearing interface rendering light" space Interface design strategy;light and shadow design strategies of "transmission","condensation","shading","filtering","dropping" and "diffusion".It provides a reference for the optimization and transformation of the Changsheng Hall in the second phase of Luyeyuan in the fifth chapter.The fifth chapter is based on the design strategy of the previous chapter in the case of optimization and transformation of the longevity hall of the second phase of Luyeyuan.From the investigation of the current situation of the Hall of Longevity and sorting out the existing problems,the appropriate design strategy is used for transformation,and finally the quantitative verification is carried out through simulation.The sixth chapter concluding remarks summarizes the main research conclusions and main research results of the paper,and puts forward the limitations of the research and the prospects for future research directions.
