Digital twin technology empowered building-integrated photovoltaic design

Abstract

This thesis explores the integration of Digital Twin (DT) technology with Building-Integrated Photovoltaics (BIPV) to enhance lifecycle management, energy optimization, and user engagement. A systematic review of current DT applications in BIPV systems is presented, highlighting the existing challenges and proposing strategies for improvement. Focusing on the early design phase of Façade-Integrated Photovoltaics (FIPV), the thesis utilizes parametric design and simulation methodologies to model and optimize the shading impact on solar radiation for a high-rise residential building in Hong Kong. The study employs regression methods to quantify shading impacts, while parametric design tools are used to evaluate and optimize the combined solar façade system. This approach demonstrates the potential of DT technology to dynamically predict and enhance the energy performance of BIPV installations, providing a real-time, iterative design process. Moreover, a case study at the Hong Kong University of Science and Technology explores the aesthetic design and user participation in FIPV. This case study involves interdisciplinary collaboration and user surveys to develop color design strategies that balance energy efficiency, aesthetic appeal, and educational impact. The findings emphasize the potential of integrating DT technology with BIPV systems to improve energy performance and architectural integration. This thesis provides valuable insights and recommendations for future research and sustainable building practices, underscoring the crucial role of DT in optimizing the design, operation, and lifecycle management of BIPV systems.
