Abstract: Photovoltaic cells in building facades convert solar radiation into electricity. Increased output is achieved by integrating both light-transmitting (windows) and non-transmitting (façade) surfaces. Optimizing window transparency improves visual comfort and reduces energy use. This study introduces a method to assess a south-facing office façade using opaque a-Si and translucent thin-film silicon photovoltaic cells. It analyzes their effects on electricity production, visual comfort, and energy consumption through simulations using Windows software, and the EnergyPlus and Radiance engines in Ladybug tools. The study consists of two main phases:
