Digital Twin
A digital model of a physical building or asset that stays connected to it through live operational data.
Full Definition
A digital twin is a digital model of a physical asset, such as a building, that stays connected to the real thing through data. In building operations, a digital twin usually starts from design information such as a BIM model and links each space and piece of equipment to its operational data: live sensor and building automation system readings, CMMS work orders, maintenance history, and documents such as O&M manuals and drawings. A static BIM file describes the building as designed; a digital twin is updated as the building is operated, so facility teams can see the current state of a portfolio, a building, a floor, or a single asset in one place. Digital twins are used for real-time monitoring, troubleshooting, maintenance planning, capital planning, and energy management.
