Construction of Indoor Physical Environment Based on Digital Twin

This paper puts forward a construction scheme of digital twin system for building indoor physical environment, and expounds the composition structure of a five dimensional digital twin system of building indoor physical environment. This paper integrates digital twin technology and BIM technology to collect data through a range of sensors and cameras. It facilitates real-time detection and dynamic display of building products, while monitoring performance changes of various equipment using an intelligent algorithm model. The primary objective is to establish a foundation for achieving green energy-saving in buildings and to offer guidance and support for building operation and maintenance.
