The workshop on digital twins of buildings and cities will offer a unique opportunity for scientists and urbanists to explore the potential of digital twins in transforming the way we design, operate, and manage buildings and cities.

Digital twins are virtual replicas of physical assets, systems, or processes that simulate and predict their performance, behavior, and interactions in real-time. Participants will gain insights into the latest advancements in digital twin technology and their practical applications in areas such as energy efficiency, sustainability, and resilience. The workshop will also examine the challenges and limits of digital twin technology, drawing on concrete examples to encourage participants to think creatively and collaboratively about potential solutions and strategies.
