Design & BIM

What is Digital Twin?

A digital twin is a living digital replica of a built asset that stays connected to the real thing: combining the as-built model with live data from sensors, occupancy, and building systems. Unlike a static BIM model, a twin updates as the building operates.

In practice

Owners use digital twins for operations: monitoring energy and occupancy, simulating changes before making them, and giving facilities teams a queryable model of what is actually installed where.
