Research On Design Optimization Of Natural Lighting System Of Terminal Based On BIM Technology

As one of the main lighting forms of the terminal,natural lighting has an important impact on the indoor space environment and energy saving of the terminal.Due to the huge size of the terminal itself,its internal demand space is lack of light.At present,the lighting design of the terminal in China is mainly aimed at the lighting design,which is lack of attention to the natural lighting.At the same time,architects generally focus on the comparison between the real and the virtual in the form,and lack of thinking about energy saving and optical design.With the gradual deepening the application of BIM technology the aided building design,the model sharing technology has the possibility of achieving the first mock exam and the efficient and quick completion of the simulation of the light environment.Therefore,this paper takes the natural lighting of the terminal as the research object,aiming to simulate and quantify the natural lighting effect of the terminal through BIM Technology,so as to assist the architectural design and achieve the purpose of optimal design.Based on the existing theory,this paper studies the natural lighting optimization of the terminal building from the perspective of architectural design.Firstly,the paper analyzes the natural lighting of the terminal,and focuses on the main design factors of the natural lighting of the terminal,including skylight lighting system,glass curtain wall lighting system,atrium and courtyard lighting system and sunshade system.Secondly,the paper summarizes the BIM Technology of light environment simulation and itsapplication in the terminal building.Finally,taking the natural lighting design of the East Air Station building of Xi’an Xianyang International Airport as an example,through BIM Technology,the paper analyzes the existing problems in the natural lighting design,and on this basis,carries out the optimization scheme design,and then through the comparison of simulation data,puts forward the optimization strategies for the natural lighting,including skylight design optimization,glass curtain wall lighting design optimization,atrium lighting design optimization Design optimization and sunshade design optimization.The research of this paper is based on the research of design theory,through the light environment simulation technology of BIM,the practical application of a terminal design case is studied,and the corresponding optimization strategy is obtained.In order to provide some valuable reference for the natural lighting design optimization of the terminal building.
