Jarrod Reedie Digital twin technology, real world clones that are utilised to monitor the status of its physical counterpart and predict its evolution, is beginning to rear its head in the built environment sector. Unlike a 3D model, digital twins are linked to a live stream of data, allowing the twin to evolve like its real world twin would. It gives creators the ability to test future performance and its possible risks, as well as creating opportunities to improve efficiency, mitigate environmental impact and reduce costs. A study conducted by Markets and Markets suggests the digital twin market, valued at $3.1 billion in 2020, will rise to approximately $48.2 billion by 2026.
