一般来说,居室的采光可用四个指标判定。 自然照明系数 指室内水平照度与同时在室外空旷无遮光物处接受全部天空散射光的水平照度的百分比。居室自然照明系数应在0.5％—0.75％。 采光系数 指采光口的采光面积{玻璃面积)与室内地板面积之比。一般居室的采光系数规定在1/6—1/8。这个系数的实际意义还受进光口朝向和前后有无 In general, the lighting of the room can be judged by four indicators. Natural lighting factor refers to the percentage of horizontal illuminance in the room and the level of illuminance that receives all the sky-scattered light at the same time in the open air without shade. Room natural lighting factor should be 0.5% -0.75%. The daylighting factor refers to the ratio of the lighting area {glass area) to the indoor floor area. The general living room lighting factor is set at 1/6—1/8. The actual significance of this coefficient is also determined by
