Abstract: Photovoltaic integrated shading devices (PVSDs) combine solar shading and electricity generation on building façades, thereby harnessing solar energy. In high-rise buildings, rooftop solar panels typically yield limited amounts of electricity relative to the energy demand of the building. Consequently, integrating PVSDs is crucial for advancing net zero-energy building initiatives. However, PVSDs may obstruct natural light penetration into indoor spaces, diminishing daylight utilization and potentially increasing lighting energy consumption. Moreover, they may compromise the visual connections between indoor and outdoor spaces. Therefore, designing PVSDs that balance energy generation, daylight utilization, and outdoor visibility is imperative. This study aimed to optimize the shape of PVSDs to effectively achieve these objectives. Specifically, the investigation focused on a PVSD composed of flexible solar panels integrated with curved louvers.
