140723 - Indoor Daylight Analysis of Window Used in Historic Buildings 

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. 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 heat gain is decreased by up to 53%, without significant negative impact on the indoor natural illumination.
