Abstract
The paper explores the use of biomimicry to enhance façade design and improve daylighting performance in office buildings in Cairo, Egypt. By emulating natural processes, adaptive facades were developed to increase energy efficiency and occupant comfort. Initial studies examined biomimicry principles and international case studies of adaptive facades. Simulations of a façade inspired by the Gazania flower's nyctinasty movement showed significant improvements: the area achieving optimal illuminance (300-3000 lux) increased from 24.2% to 37.4%, and Spatial Daylight Autonomy (SDA) has decreased from 82% to 68%. These findings demonstrate biomimicry's effectiveness in addressing daylighting challenges in hot climates. The research underscores biomimicry's role in sustainable architecture, offering benefits like reduced energy consumption, minimized environmental impact, and improved occupant comfort. The study recommends further research, material innovation, and policy initiatives to advance biomimetic façade design, paving the way for environmentally responsive and aesthetically pleasing buildings.
