典型外窗和遮阳类型对福建地区住宅室内光环境的影响

Effects of typical windows and shading types on indoor light environment of residential buildings in Fujian

以福建地区住宅建筑主要功能房间的调研数据为基础,利用模拟软件Ecotect分析窗户尺寸、窗台高度等因素对室内照度的影响程度,总结出在房间设计时,选择扁平窗户、合适的窗台高(0.6~1.0m)以及选择窗高、窗宽越大,越有利于室内采光。同时也分析了水平遮阳和垂直遮阳引起的室内照度分布,提出遮阳构件挑出长度越短、遮阳构件到窗对面距离越大,室内照度越大,越有利于室内采光,且相对于垂直遮阳,水平遮阳下室内照度较低,对室内采光的影响较大。

Based on the survey data of the main functional rooms of residential buildings in Fujian,the influence of window size,sill height and other factors on the indoor illumination is analyzed by using the simulation software Ecotect. It is concluded that in the room design,the selection of flat windows,the appropriate sill height(0. 6m ~ 1. 0m) and the larger the window height and width are,the more conducive to the indoor daylighting is. At the same time,the indoor illumination distribution caused by horizontal shading and vertical shading is also analyzed. It is proposed that the shorter the length of the sunshade component,the greater the distance from the sunshade component to the opposite side of the window,the greater the indoor illumination,which is more conducive to indoor daylighting. Compared with vertical shading,the indoor illumination under horizontal shading is lower,which has a greater impact on indoor daylighting.
