The leakage of air cooling through transparent facades and the transfer of solar radiation through glazed windows have led to increased energy consumption in buildings. To address this issue, a concept has been proposed wherein a fully glassed-in facade acts as the building envelope, resulting in energy savings on air conditioning. Glazing plays a crucial role in daylighting, thermal comfort, and heat transfer between indoor and outdoor spaces. To enhance glazed windows for solar protection and energy efficiency, there are two approaches: applying film coatings to existing windows or replacing single-glazed windows with double-glazed alternatives. In this research, we aim to investigate the energy-saving potential of these approaches using energy simulation through EnergyPlus. For this case study, we utilize the OpenStudio SketchUp Plug-In, an interface software introduced through the United States Department of Energy. Our simulated results demonstrate that the addition of film coatings to existing glazed windows effectively reduces energy use. The amount of energy savings depends with the color of the film coating. which should range between 2.50% and 0.61%. Additionally, replacing single-glazed windows with double-glazed alternatives yields positive results, with a simulation error not exceeding 1.78%. It is crucial to note that economic outcomes for individuals may significantly vary from those discussed in this research due to factors such as diverse wall and roof types, climate variability, and occupant habits. These variables contribute to diverse outcomes beyond the scope of this study.
