Study On The Optimal Design Of Natural Light Environment For Exhibition Hall Of Garden Expo

With the successful bid of the garden fair at home and abroad,the number of the main building exhibition hall in the corresponding garden fair is also increasing.As an exhibition type building with new characteristics and new technology and new materials,it has a broad space for development.At the same time,in order to adapt to the new concept of green energy saving and environmental protection,people have higher requirements for the energy efficiency of exhibition hall.The exhibition space is the core space of the exhibition hall,and the light is the core issue of the exhibition space.Therefore,the research of the natural light environment of the exhibition hall is meaningful.Therefore,this paper attempts to take the exhibition space and natural light as the object of study,aiming to conclude the passive and active methods of lighting design in exhibition space through theoretical and empirical support,and extend and apply it.At first,this paper using the method of case analysis of the domestic garden expo exhibition space natural lighting using instance,use daylighting simulation analysis software analyzes the present situation of the internal space of natural lighting,summarizes the problem of garden expo pavilion natural light environment in our country,and then to the garden expo pavilion architectural features and spatial features are studied,and on this basis,combining with the natural lighting of the architecture,the garden expo show and public space are natural light environment characteristic and the demand for the summary,and through a variety of passive and active natural lighting technology for the two major function space optimization design method is put forward.Finally to apply method for the optimization design of active and passive Huang Shiyuan expo exhibition project of two large space during design phase,by comparing lighting simulation software to optimize the indoor natural light before and after changes in the environment,to demonstrate the effectiveness of the optimization design method.This paper attempts to combine theory with practice,makes this study can provide some ideas for future domestic pavilion light environment design and methods,and to improve the energy efficiency of pavilion offers some practical and effective way.
