In light of the energy crisis, population growth, urbanization, and environmental pollution, the demand for rational energy use has become crucial. Buildings, particularly office buildings with their extensive use of glass facades, consume a significant portion of the world's energy sources. This is largely due to their envelopes, where the choice of glazing plays a critical role. Therefore, optimizing building facades, especially in office buildings, is vital in achieving energy efficiency and improving indoor comfort. Conventional glazing types, while standard, often fall short in dynamically responding to changing environmental conditions, leading to increased energy demands. In contrast, electrochromic (EC) window systems have emerged as innovative solutions, claiming the ability to dynamically adjust their optical properties based on sunlight and cloud conditions. These systems meet the needs of solar control, thermal insulation, and natural lighting according to instantaneous weather conditions while also ensuring thermal and visual comfort. This study aims to evaluate and compare the energy performance of electrochromic windows on different facade orientations of an office building with various conventional glass types in different climatic zones. It focuses on heating, cooling, and lighting loads, along with the energy consumption of the electrochromic glass, aiming to identify the most energy-efficient solution for each orientation. The findings of this study will be used to make decisions related to the selection of glazing systems for different orientations in different climatic zones, considering the specific energy performance, visual comfort, and daylight utilization requirements of an office building.
