遮阳通常被认为用于炎热或类似的气候;然而，在某些具有高太阳辐射和高昼夜温度变化的气候中，窗户的遮阳也是必要的。适合这种气候的典型遮阳类型是八字窗。通过正交试验设计，确定了影响八字形窗采光遮阳性能的因素，并对影响因素进行了排序。接下来，通过Radiance和Daysim的一系列模拟，研究了拉萨西向窗口的尺寸因素的详细影响。结果表明，外窗与内窗的面积比和朝向对采光和遮阳的综合性能有显著影响，西向是该窗的最佳选择。在其他地点亦有类似的表现，RDA/SC与入射太阳辐射有很强的正相关关系，而八字形窗在太阳辐射高的地点，在遮阳和采光方面会更有效。
Solar shading is generally considered to be used in hot or similar climates; however in certain climates with high solar radiation and high diurnal temperature variation, solar shading for windows is also necessary. A typical type of shading for this climate is the splayed window. An investigation of the performance of daylighting and solar shading of this window type can benefit the solar shading design for similar climates.This paper identifies the influencing factors of the splayed window type in daylighting and solar shading and ranks their importance factors via an orthogonal experimental design. Next, the detailed effects of the dimensional factors are investigated for a window of western orientation for a case in Lhasa via a series of simulations using Radiance and Daysim. Afterwards, the performances of this window type in other locations are examined.The results reveal that the ratio of the exterior and interior window opening areas and orientation have significant influences on the integrated performance in daylighting and solar shading, and the West orientation is identified to be the best for usage of this window type. Similar performances are found in other locations andRDA/SCis found to have a strong positive correlation with the incident solar radiation and the splayed window will be more effective in locations with high incident solar radiation in terms of solar shading and daylighting.
