Abstract

The rising global population has resulted in a higher demand for energy, specifically in the building sector. Therefore, strategies aimed at increasing energy efficiency while meeting the needs of occupants, particularly in office buildings, play a crucial role in ensuring environmental sustainability. Moreover, adequate levels of daylighting, while contributing to an improvement in the visual comfort of occupants, produce heat, which may lead to an increase in cooling energy demand, especially in hot and arid climates. Therefore, in light of the energy crisis in recent decades, it is imperative to take into account these criteria, energy consumption and visual comfort, in architectural designs. One of the effective methods for improving energy efficiency and sustainability in buildings is adaptive shading devices, which can be utilized in a variety of settings due to their ability to adapt and dynamically adjust to the sun’s position. This research aims to explore the potential of adaptive shading devices for optimizing daylight and energy consumption efficiency simultaneously. The research method in this study is practical and quantitative in terms of purpose. In terms of the methodology used for the work, the experimental and simulation method has been used. The Rhinoceros software is used to model the reference room, which is a 6m by 6m office space assumed to be on the third floor of a 4-story building. The Ladybug Tools plugin is then employed to simulate various scenarios for each season. These scenarios include "no shading devices", "extruded borders" and "retractable shading", for the southern façade of the office space with a window-to-wall ratio of 40%. A total of 200 design alternatives are evaluated to determine the Pareto frontier for each season. The results indicate that by using adaptive shading devices on the southern façade of office buildings in Isfahan, daylight levels can be optimized up to 20% while energy consumption can be reduced by more than 48%.
