摘　　要：目的 为解决东北地区教学建筑中自然光分布严重不均衡,而单纯依靠粗放式地提高窗地比采光计算方法无法改善,通过设置导光构件解决自然光分布不均衡的难题。方法 应用Ecotect软件建立典型教室空间和导光构件的参数化模型,分析导光构件内外位置、水平高度、截面尺寸、截面形态、透光度等参数变化对于采光系数、照度、采光均匀度等参数的影响。结果 通过对模拟数据的比较分析发现,导光板在位于侧窗室内一侧、高度为2 400 mm、截面宽度为1 050~1 200 mm、截面形态为弧形向下的情况下,采光照度和均匀度达到最佳平衡状态;导光百叶中的水平内倾百叶的综合性能优于其他类型。结论 横向比较,导光板最优方案在综合性能上优于导光百叶,是东北地区较为适用的导光构件。The distribution of natural light in the space of the educational building in Northeastern of China is severely uneven.Increasing the ratio of the window to ground just by the lighting calculation cannot improve indoor light environment,but light guide components is a practical and effective solution.A parameterized model of typical space in a classroom with light guide member was established by Ecotect software.The impacts of parameters for light guide member such as the internal and external positions,upper and lower positions,cross-sectional dimensions,cross-sectional morphology,and transmittance on the performance of lighting coefficient,illuminance,and daylighting uniformity are analyzed by the daylighting simulation analysis method.Through comparative analysis of simulated data,it was found that the optimal solution for achieving a balance between lighting illumination and uniformity was achieved when the light guide plate was located on one side of the side window,with a height of 2400 mm,a cross-sectional width of 1050~1200 mm,and a curved inward section shape;the comprehensive performance of the horizontal inward inclined louver in the light guide louver is superior to other types.However the optimal scheme for the light guide plate is superior to the light guide louver in the comprehensive performance.So the light guide plate is the most suitable light guide component in the Northeast region.
