窗户让日光自然照亮室内空间，节省照明能源，创造健康的工作环境。然而，过多的日光会增加热量，并导致眩光不适。因此，外部屏幕用于控制日光。融入Mashrabiya等古代设计屏幕不会改变建筑的传统设计。传统屏幕提供自然光、自然通风和隐私。Mashrabiya是一种由建筑材料（如木材或吉布森）制成的纵横交错的条状结构。在本研究中，我们进行了实验测量，以研究安装穿孔屏对室内照度水平和通过窗户的热增益的影响。在6月份测量了窗户室内表面的温度和热流。测量了室内空间的照度水平、室内外空气温度以及现场的总太阳辐射。 窗户朝西。考虑了屏幕的几种设计模式。热增益降低高达53%，对室内自然光照没有显著的负面影响。引文:2016年3月14日至16日在科威特召开的第六届国际能源研究与开发会议

Windows allow the daylight to naturally illuminates the indoor space, save energy for lightings, and create healthy working environment. However, excessive daylight increases the heat gain and causes discomfort glare. Therefore, external screens are used to control daylight. Incorporate ancient design screen such as Mashrabiya will not alter the traditional design of the building. The traditional screen provides natural light, natural ventilation, and privacy. Mashrabiya is a framework consists of a crisscrossed pattern of strips made of building material, such as wood, or Gibson. In this study, experimental measurements have been conducted to study the effect of installing the perforated screen on the indoor illuminance level and heat gain through the window. The temperature and heat flux at the indoor surface of the window are measured in the month of June. The illuminance level in the indoor space, indoor and outdoor air temperatures, and global solar radiation in the site are measured. The window is facing west direction. Several design patterns of the screen were considered. The heat gain is decreased by up to 53%, without significant negative impact on the indoor natural illumination.
