The optimization of Building Integrated Photovoltaics Systems in Urban Environments

The utilization of Building Integrated Photovoltaic (BIPV) systems in high-rise urban buildings is limited despite their potential benefits in reducing electricity costs and greenhouse gas emissions. This paper introduces an advanced methodology that comprehensively evaluates BIPV system performance in high-rise buildings. The approach considers facade orientations, rooftop areas, and PV panel types to assess energy generation potential under different scenarios. Microclimate data obtained using the Urban Weather Generator (UWG) is incorporated for a thorough analysis. A case study on a super high-rise building in Hong Kong demonstrates the effectiveness of the proposed method and highlights the BIPV system's potential. The paper emphasizes the importance of optimizing BIPV systems in urban settings by considering various factors to maximize their effectiveness.
