Biomimicry as an Approach to Improve Daylighting Performance in Office Buildings in Assiut City, Egypt

Biomimicry inspired architects to solve complex design problems and develop adaptive solutions for enhancing the environmental quality. Fields of inspiration include energy efficiency, natural ventilation, daylighting, structural stability. In this paper, 144 biomimicry-inspired building skin alternatives have been developed improve daylighting performance in office buildings Assiut City, Egypt; 72 are 0.5 m frame depth, other 1.0 depth. Two levels biomimicry; namely, organism level (snakeskin) behavior (plants tropism), adopted. Alternatives be simulated ClimateStudio plug-in Rhino accordance with international rating system leadership (LEED v4.1). The evaluation criteria spatial Daylight Autonomy (sDA), Annual Sunlight Exposure (ASE), Average Lux (AAl), Spatial Distributing Glare (sDG). An point has evaluate using Analytical Hierarchy Process (AHP) based on feedback 14 faculty architecture members. Nine succeeded achieve notable improvement (from 16.69% 33.73%) compared base cases. general, frame-depth achieved better results improving than alternatives. most effective parameter was rotation angle unit used, followed by distance between façade, solid-to-void ratio skin, number units constituting system, horizontal bending unit, respectively.
