Evaluating Daylighting Performance of Parametric Mashrabiya in Mediterranean Climate: A Simulation-based Approach
Year: 2025
Type: article
Abstract: This study examines the daylighting performance of parametric Mashrabiya-inspired shading devices in a Mediterranean climate, aiming to enhance occupant comfort and visual performance. Using Grasshopper/Rhinoceros for motif design and Climate Studio for annual daylight simulations, 21 shading patterns were evaluated by varying opening ratios (30%, 50%, 70%), depth angles (30°, 45°, 90°), and directions. Metrics such as Useful Daylight Illuminance (UDI), spatial Daylight Autonomy (sDA), and Annual Sunlight Exposure (ASE) were used for performance assessment. Four scenarios with a 50% opening ratio and either downward or eastward-facing depths achieved balanced daylight sufficiency, with sDA values between 57.4% and 65.3%, ASE values from 0.5% to 7.4%, and UDI-a between 54% and 61.5%. The study highlights the potential of combining traditional Mashrabiya with modern parametric design to create energy-efficient, culturally responsive façades. Future research should explore in-situ validation and kinetic Mashrabiya systems for dynamic daylight control.
