The Effect of Geometry Parameters on Daylighting of School Buildings in the Gaza Strip

School buildings have a significant potential for daylighting to improve school students’ academic performance in terms of rational, behavioral, and physical aspects; of their education and activities. This paper discusses the role of geometry parameters, including building shape, annual sun exposure (ASE), and spatial daylight autonomy (sDA) of single-sided school buildings in the Gaza Strip, Palestine. The daylighting of five shapes was compared through computer simulations using ClimateStudio software. It has been noted that geometric shapes, such as L, C, H, F, and E-shapes, are the most popular shapes, especially in governmental schools in the Gaza Strip. Results showed that each shape has a different impact on daylighting. The E-shape performed the optimal shape, with 84.5% for sDA and 19.1% for ASE, with various design options to determine the stability of increasing or decreasing the amount of artificial light needed per day. A 40–60% window-to-wall ratio had the optimal daylighting quality performance. However, deeper rooms required a higher window-to-wall percentage to reduce the lighting demand.
