Abstract: Jaali is an Urdu word for traditional latticed screens, also known as mashrabiyas, widely used in most building typologies in hot climate zones, particularly in South Asia, Middle East, and parts of Europe. The objective of this study was to use a simplified version of a Jaali and demonstrate the application of evolutionary computing process for optimizing the perforation ratio for daylight performance. This was done by creating the basic room geometry in Rhino6; then adding the Jaali definition in Grasshopper3D (GH); and finally, using a multi-objective optimization engine called Octopus that runs within GH to optimize the perforation ratio for performance objectives.
Keywords: Jaali screens, perforated screens, daylight performance, genetic computing, multi-objective optimization
