The concept of a digital twin has been around since the early 2000s (predominantly in manufacturing, aerospace, automotive and engineering disciplines) however only in recent years has the Twin been within reach in our industry thanks to improvements in IoT, bandwidth and processing power. A digital twin can be defined, as an evolving digital profile of an asset, a bridge between the physical and digital world, that collects and tracks behaviour over time and utilises this data to optimize asset performance. The Twin is powered by real-time, real-world data across an array of dimensions. But how does a digital twin benefit users? This presentation will share case studies on how Willow is using the digital twin in both commercial/corporate office and infrastructure to improve the asset performance and occupant / user engagement.
