Historical buildings contain stories of the past, cultural characteristics, and artistic styles, offering a glimpse into the historical development and the way people lived. These buildings have cultural, economic, landscape, and social value, necessitating well preservation. Dr. Jiaying Zhang, who taken her master's studies in sustainable heritage at University College London from 2016. Subsequently, she conducted research in the field of architecture and engineering intelligence at Tsinghua University and Hong Kong University of Science and Technology. She has been devoted to the study of in-depth theories, policies and advanced methods of the preservation of historical buildings. Her research activities span across various climatic zones, including mainland China, Hong Kong SAR, London, and Malta. Dr. Zhang's team has created digital twins of historical buildings that not only support the preservation of their current state but also provide accurate databases for the future renovation and emergency management of these buildings.
Historic buildings are characterized by complex morphology and have often undergone changes over different eras, such as function transformation, and shifts in technology and regulation, often lack clear and traceable construction records. Dr. Zhang's team proposed a solution to the lack of information by integrating documents, data, and graphics into the information model for heritage building preservation (Heritage Building Information Modelling-HBIM). The team also improved HBIM modeling methods for buildings with regular and irregular geometries, supporting Computational Fluid Dynamics (CFD) simulations for the preservation of historical buildings. Moreover, team members Zhenyu Liang and Jeff Chak Fu Chan have efficiently reconstructed three-dimensional models of historical buildings with high precision based on the 3D Gaussian Splatting (3DGS) technique, accurately restoring real scenes of historical buildings and developing lightweight models for complex buildings, facilitating the rapid establishment of virtual tour experiences.
