摘要
建立了玻璃幕墙光污染的测量模型,以目标幕墙的照度和亮度作为主要测量指标,从而确定影响玻璃幕墙光污染其他主要因素。以沈阳华润大厦为例完成玻璃幕墙光污染影响程度的实地监测与评价分析,得出玻璃幕墙光污染主要影响因素为测量仰角、相对幕墙的方位角和测量距离;玻璃幕墙光污染影响程度和影响范围随环境的变化而变化;当目标玻璃幕墙的反射光亮度小于10 000 cd/m2时,对人视觉影响较小,当亮度大于200 000 cd/m2时,出现反射光最强点,对人视觉影响较大,人们难以忍受。最后,基于建立的测量方案和评价理论对沈阳市典型玻璃幕墙的光环境进行监测与评价,以建筑物高度、仰角、眩光等级、距离、照度、亮度、周围环境、天气状况作为评价指标,结果表明沈阳市太原街商圈和华润大厦附近光污染最为严重。
With the development of modern architectural design, the frequency of using glass curtain wall was increased, resulting in the aggravation of light pollution. In the article, the measurement model of glass wall light pollution was established, taken the brightness and illumination intensity of target wall as the main index, which was to determine the other factors that influence the glass curtain wall light pollution. Taking the Shenyang Huarun Building as an example to monitor glass curtain wall' s light pollution, there are some conclusions: the main factors of glass curtain wall light pollution are the elevation, azimuth and measuring distance. As the environment is changed, the extent and range of the glass curtain wall light pollution changed. When the reflective brightness of glass curtain wall is less than 10 000 cd/m2 , there are less impact on human vision. It is unbearable for human to bear over 200 000 cd/m2 , when the strongest points of reflected light appears, light pollution has a great impact on human vision. The paper also evaluates the overall light environment of Shenyang, taking building height, elevation, glare rating, distance, illumination, brightness, and ambient weather conditions as the evaluation index. The results show that Shenyang Taiyuan Street and Huarun building have serious light pollution.
