PARAMETRIC ISLAMIC GEOMETRIC PATTERN FOR EFFICIENT DAYLIGHT AND ENERGY PERFORMANCE Façade retrofit of educational space in hot arid climate

The purpose of this paper is to reach an optimal Islamic geometric pattern (IGP) shading screen design in terms of daylight and energy performance in an existing educational design studio (EDS) using generative design and simulation techniques. The study was carried out in a hot arid climate, in a typical EDS in 6th October University, located in Cairo, Egypt, and the study focused on the north-east oriented façade. Grasshopper for Rhino was utilized to generate the IGP parametric variations. Diva-For-Rhino which performs daylight analysis using Radiance / DAYSIM, and Design Builder which performs thermal load simulations using EnergyPlus were utilized in simulation. The results of the study achieved the required daylight levels with significant reduction of energy consumption levels of cooling load. This shows the affordance of the parametric IGP shading screens in façade treatment for achieving both efficient daylight and energy performance in educational design studio in hot arid climates.
