摘要
为溯源北京传统四合院的天然光环境,本研究对窗纸材料进行了物理测量和模型实测校核,建立了典型的北京四合院模型,对正房和厢房的天然光进行了全年逐时动态模拟,并通过与玻璃的性能比较,梳理窗纸的光学意义。研究发现,相比玻璃窗而言,纸窗的光环境特点如下:(1)除提升了正房后墙面照度外,降低了地面、工作面、东西厢房后墙面等多数区域的照度,缩小了照度的季节性差异;(2)提高了照度均匀度;(3)除正房冬季远窗区外,降低了多数位置的眼部曝光量;(4)降低了东西厢房的眩光几率。
In order to trace the daylighting condition of Beijing traditional Siheyuan(courtyard),this research has conducted physical measurements and modelling validation experiments of window paper;established typical models of Beijing Siheyuan;carried annual dynamic daylighting simulations in the main room and wing rooms;clarified the lighting significance of window paper by comparing it with glass.The research has found that in comparison with glass,the window paper holds the following features:(1)It can increase the illuminance level of the rear wall in the main room,yet decrease that of floor,working plane in all rooms and the rear walls in the wing rooms.And it can also reduce the seasonal illuminance differences;(2)It can improve the illuminance uniformity;(3)It can reduce the eye exposure in most positions except areas away from the window in the main room in winter;(4)It can reduce the chance of daylighting glare in the wing rooms.
