Abstract

Today, solutions for reducing energy consumption in buildings to protect non-renewable energy resources are essential and have received significant attention from researchers. Creating appropriate lighting conditions in office spaces is one of the most important factors in design, impacting both mental and physical conditions, as well as reducing energy consumption. A significant element in Iranian architecture is the "shabak" skylight, which plays a crucial role in controlling glare, enhancing energy efficiency, and optimizing daylight in buildings. This research aims to develop an optimized shabak pattern model to improve daylight quality and reduce glare. Initially, the study conducts a review and preliminary analysis of the shabak element. Subsequently, the architectural details and energy consumption of a selected administrative building in Kerman are simulated and analyzed using specialized software. The research utilizes Rhino software and plugins such as Grasshopper, Ladybug, Honeybee, and Radiance Engine for daylight simulation. Additionally, the Galapagos tool, with its genetic algorithm-based optimization capabilities, is employed. Data analysis results show that the optimal aperture scale is 156.79 in the middle state with a maximum of 207.36 centimeters. The absorption point position ranges between 27 to 31, with an absorption radius of 0.9 to 1.1 meters. The geometry of the shabak pattern has effectively enhanced the quality of daylight, resulting in a 54% increase in useful daylight illuminance and a 15.6% reduction in annual glare.
