Facade Solar PV Potential Estimation considering Rooftop Capacity and Building Code for Indian Cities

Abstract

In Urban areas buildings, the potential to harvest solar energy through facade is larger compared to the roof. Effective faade area available to harvest solar energy is influenced determined by the building bye-laws and also the national building codes, especially fire safety norms. Its potential depends not only on the geographical location but also on surrounding entities. Since BIPV has to must be implemented in the design phase of the building, accessing its potential for deploying appropriate technology is important. In urban areas, the solar potential is greatly affected by the shadowing from the surrounding objects such as trees, buildings, and, urban furniture. Solar potential is also influenced by geographical parameters such as climate, longitude, and latitude. Rooftop potential data, policies, and case studies are readily available for most developing countries but not the facade potential. In this study, we will estimate the facade potential for the Level of Detail 1 from the geographical information, roof potential, and the building codes of the respective city.
