The SURE (Smart Urban Resilience Enhancement) project, launched in November 2024, represents a cutting-edge collaboration between e-GEOS, the European Space Agency (ESA), and a multidisciplinary consortium including Stefano Boeri Architetti’s Research Department. This initiative explores the transformative potential of Urban Digital Twins to address the most pressing challenges posed by climate change: Extreme Heat Events (EHE) and Urban Floods (UF). 

Digital twins are sophisticated virtual replicas of urban environments that allow for the real-time monitoring of territorial dynamics. By integrating multi-platform data from satellite Earth Observation (EO), remote sensing to in-situ sensors and climate modelling systems (PALM) the SURE project develops simulation scenarios that ground architectural and spatial decisions in empirical evidence. For architects and planners, this means the ability to visualize and test design interventions before they are implemented, significantly improving the long-term impact and sustainability of urban projects. 

The project specifically targets two critical urban phenomena: Urban Heat Islands, identifying the detailed microclimatic impact of different project scenarios, based on their material, vegetation and disposition in the urban space; and Urban Flooding, simulating various precipitation scenarios, enabling the evaluation of flood risk levels and identifying most vulnerable assets.  

Research conducted during the project highlights a growing professional demand for these tools; while 87% of surveyed professionals are aware of the Heat Island phenomenon, only 25% currently utilize satellite-derived Land Surface Temperature (LST) data in their workflows. The projects seeks to bridge this gap and develop a prototype that in future could be integrated in the design process.  

Furthermore, the SURE Digital Twin is designed for integration into the Destination Earth (DestinE) platform, a European Commission initiative aimed at creating a high-precision digital model of the entire Planet. By fostering interdisciplinary collaboration and providing a platform for “Ante vs. Post Operam” comparisons, SURE aims to empower the architectural community to design more resilient, climate-adaptive cities.
