 Photovoltaic, PV, curtain walls are a promising solution to reduce carbon emissions due to their ability to generate clean, renewable energy from sunlight. This paper assesses the carbon emissions of PV curtain walls by analyzing the impact of various factors such as orientation, location, inclination, shadow occlusion, and seasonality. The results show that the degree of these factors influence on carbon emissions varies depending on the scenario. In general, the most significant factor affecting carbon emissions is orientation, followed by location, inclination, shadow occlusion, and seasonality. These findings suggest that PV curtain walls have great potential to reduce carbon emissions, but more research is needed to optimize their design and maximize their efficiency.
