Research And Application For BIM Technology In Building Indoor Daylighting And Green Lighting

Building indoor light environment directly affects our health, work efficiency, and the art of vision from the construction. With the continuous development of lighting technology, formerly, it focused on lighting design function and form which is gradually toward to the direction of more comprehensive. Lighting design from building space is gradually to be diversification, as well as the promotion of sustainable green lighting for the past couple of years. Especially, to talk about the reasonable and efficient from natural lighting, as well as the combination of natural lighting and artificial lighting research, they will be more widely and deeply.This thesis mainly put building indoor lighting and artificial lighting as the main-line, combined with BIM(Building Information Modeling) technology in the development of information technology, from the various professional building information model to be built into the related parameter setting and building indoor light environment simulation, analysis and summary. This thesis mainly out building indoor lighting and artificial lighting as the main-line, combined with BIM technology in the development of information technology, from the various professional building information model to be built into the related parameter setting and building indoor light environment simulation, analysis and summary. Respectively from the BIM technology and the development of architectural lighting, required the professional model, based on BIM light environment simulation analysis and the green lighting energy saving control, etc.The main contents are outlined as follows:(1) In this thesis, BIM technology as the core technology of building light environment analysis,building information model which serve the building light environment is built. BIM technology is being as the new plan from the major design institute in recent years. The model from the required professional to be built, from establishing the required template, professional working set for model building, introduction of BIM model design method and process.(2) To analyze the three common light source(the point light source, the line light source and light source) features, and the relationship between light and space; In the paper, show an engineering case as an example, how to build the building information model, through the comparison and analysis of three different light sources, it highlights the importance of artificial lighting light source choice.(3) Compared with the light illumination in the BIM model from three common different light source, using digital and graphical analysis, by comparison with the corresponding illuminance analysis, to do electric lighting design and control.(4) Building green lighting and energy-saving control analysis, on the one hand, control the shutter opening, not only can satisfy the requirement of indoor intensity of illumination, but also to have the shading effects, so as to avoid discomfort caused by the human eye dazzle light. On the other hand, to be used BIM technology in advance, to analyze the status of building indoor light environment and artificial lighting lamps and lanterns, type, number of the digital control, and the late operation and maintenance of the orientation, management and cost analysis of lamps and lanterns.
