Design of a Dynamic Building Façade Using Iranian Architectural Patterns for Daylight an‎d Energy Optimization

One of the most important issues facing humanity today is the question of energy. In the field of building construction an‎d architectural design, societies are moving toward sustainable architecture in response to this challenge. Among the architectural elements that significantly influence the amount of incoming daylight an‎d the building’s energy consumption, the building façade plays a central role, as it is in direct contact with the surrounding environment. Facades come in various forms, one of which is the dynamic (movable) façade. Due to their flexibility, adaptability, an‎d responsiveness, dynamic façades can adjust to environmental conditions in alignment with sustainability goals, making them a suitable option for sustainable architectural design. At the same time, traditional Iranian architectural patterns in façades—such as Orosi (stained-glass sash windows) an‎d Shanashil—were inherently aligned with sustainable objectives such as daylight control an‎d energy efficiency. Based on this, we concluded that combining dynamic façades with Iranian architectural elements can lead to successful design outcomes. Accordingly, this research proposes a façade design inspired by the traditional Orosi. The proposed façade is capable of creating six different dynamic states, which optimize incoming daylight an‎d consequently reduce the building’s energy consumption. Simulation results show that in the climatic context of Tehran, the design reduced energy consumption by 9%; in Yazd by 12%; an‎d in Ban‎dar Abbas by 10%. However, in Tabriz’s cold climate, the design did not consistently achieve energy reduction. Therefore, while the proposed façade proved effective in three climates an‎d successfully met its objectives overall
