A Digital Twin Platform Based on 3D Building Models and Smart IoT for a Climate-Resilient Campus: A Case Study of National Taiwan University

This research focuses on “3D building modeling” and “static and dynamic information integration environment” from the perspective of the digital twin. It demonstrates the effective use of the digital twin for visualizing information associated with a 3D environment, such as sunlight exposure and temperature, which are used as comfort indexes. Furthermore, the developed platform provides real-time display and analysis of the campus environment through the intuitive dashboard. Compared with the previous 3D information platforms, which are mainly based on static information display and pre-simulation, this research proposes a real-time information management environment through the combination of virtual 3D objects within the 3D WebGIS interface, the customized server, and the database, which can dynamically update the information of objects when events occur in reality. National Taiwan University is used as a study case to show how the digital twin helps make decisions from multiple scenarios and provides real-time suggestions.
