What Is a Building Digital Twin?
A digital twin is a virtual representation of a physical asset that is connected to real-world data and updated in real time. In the context of buildings, a digital twin can range from a simple 3D model linked to a maintenance database all the way to a sophisticated simulation that replicates the building's thermal, electrical, and mechanical behavior in real time and can be used to predict future performance, test operational changes, and automate building systems.
