We are pleased to announce our new paper, "A digital urban twin enabling interactive pollution predictions and enhanced planning,” was published in the journal Building and Environment. This work was made possible through the contributions of Dennis Teutscher, Fedor Bukreev, Adrian Kummerländer, Stephan Simonis, Peter Bächler, Ashkan Rezaee, Mariusz Hermansdorfer, and Mathias J. Krause. This paper presents a novel approach for developing a digital twin of a city. By leveraging the computational power of GPUs in combination with the OpenLB simulation software, it becomes possible to dynamically update simulations using meteorological data such as wind speed, wind direction, and pollution levels. This enables real-time observation of pollutant dispersion and airflow patterns. The integration of automated geometry generation from OpenStreetMap data further allows the system to be adapted to various urban environments and scenarios. This approach provides valuable support for advanced urban planning and decision-making by architects and policymakers.
