| Since the 1980 s, glass curtain wall fa?ade began to appear as a new matrial. In1990 s, glass curtain wall became more and more popular with its unique modern style and superior energy performance. A large amount of buildings dressed with glass curtain wall appeared in this period of time. By now, the glass curtain wall has become the prority material for super-high buildings and high buildings facades. But when people enjoy the aesthetic pleasure and convenience brought by glass walls apart, the light pollution caused by glass walls, especially the glare pollution, has quietly taken behind the scenes, become the urgent issure which need to be solved immediately.This study chose glare pollution as the objective of study. After fulled explored the formation mechanism and laws of reflected light pollution, my study simulated sunlight in laboratory, measured reflected light intensity using a luminance meter, and did correlation analysis by spss of the experimental results. Intended to explore the results and the laws of the glass curtain pollution. And put forward practical and effective suggestions and measures to prevent glare pollution.The main contents are as follows:(1) Discuss and analyze hazard and classification of glare pollution. Conclude the content, methods and evaluation methods correspond of glare measurement.(2) Choose GR glare value system as the evaluation method based on glass curtain walls glare pollution. Determine the physical parameters and measurement methods. And have the experiment of reflected light collection, come up with the optimum measuring position.(3) Selection the luminance meter as reflected light luminance acquisition, design the measurement solutions and measurement model.(4) Build glass walls glare pollution model in the lab, use the luminance meter brightness measured and quantified glare pollution. Discuss the influence caused by the reflectivity of the glass samples, as well as the month, and the angle of incidence. |
