Daylight is one of the most important factors influencing the quality of the work environment an‎d the physiological an‎d psychological health of office employees. Appropriate access to natural light has been shown to increase productivity, improve mood, reduce eye fatigue, an‎d enhance users’ sleep quality, while simultaneously decreasing energy consumption. Considering these positive effects, effective control of daylight penetration into interior spaces, especially in cities with high solar radiation such as Tehran, is a fundamental requirement in the design of office buildings. To achieve a healthier environment an‎d improve visual comfort, the use of adaptive an‎d controllable shading devices is essential. These systems enable designers to adjust the amount an‎d angle of incoming sunlight according to climatic conditions an‎d spatial orientation, thereby preventing glare an‎d direct disturbing radiation. In recent years, inspiration from nature an‎d biological processes, particularly the movement an‎d behavior of leaves an‎d petals, has emerged as an innovative strategy in the design of intelligent shading systems. Biomimetic shading devices, with the ability to change their form in response to solar altitude an‎d azimuth, play an effective role in enhancing daylight quality an‎d reducing visual discomfort. The main objective of this study was to design an‎d eva‎luate an adaptive shading device inspired by plant movement an‎d to assess its performance in an office room located in Tehran. To this end, the geometry an‎d operation of the shading system were modeled an‎d simulated in Rhinoceros using the specialized Honeybee an‎d Ladybug plugins. By employing the Design Explorer tool, all possible configurations of the shading device were analyzed an‎d compared based on LEED daylighting criteria. Ultimately, the optimal static shading form was selec‎ted, capable of providing satisfactory performance throughout the entire year while meeting daylight comfort an‎d energy-saving requirements in office environments. This research can be regarded as a scientific an‎d practical reference for the development of intelligent an‎d environmentally responsive facades.
