摘要
眩光是遮阳控制中考虑的重要因素,当前对遮阳设备的控制大多为基于阈值的控制,而已有研究表明,人员的眩光感觉不仅与眩光水平的绝对大小有关,还与其刺激时间、变化情况有关。为更全面地认识不同眩光水平下人员的视觉响应,为遮阳控制策略的制定提供依据,对办公建筑DGP(Daylight Glare Probability,日光眩光概率)的典型变化趋势进行了分析。基于对上海典型办公建筑的调研设置了光环境模拟的代表性工况,通过对代表性工况的DGP变化曲线的模拟结果进行聚类分析,获取典型DGP变化曲线,分析其变化特点。这些曲线分段处理后,经预先建立的DGP-Ev映射模型,可作为眩光实验中调节人工光源的依据,也可进一步应用于遮阳控制策略的制定。
Glare is an important factor considered in the control of shading.At present,most of the control of shading is based on the threshold.However,several studies have shown that the glare sensation of occupants is not only related to the absolute level of glare,but also related to its stimulus time and the trend of change.In order to better study the visual response of people under different glare levels and provide the basis for the formulation of shading control strategy,the typical change trend of Daylight Glare Probability(DGP)in the office building was analyzed.The light environment simulation is set up based on the investigation of typical office buildings in Shanghai.The typical curves of DGP are obtained through clustering analysis of the simulation results of the DGP curve of representative condition with analysis of their characteristics.After subsection treatment,through the DGP-E,mapping model,these curves can be used to adjust the artificial light source in the glare experiment.They can be further used in the formulation of the control strategy of shading.
