Shaping the Future of Urban Climate Intelligence

The Smart City Mannheim is demonstrating how artificial intelligence and dense sensor networks can support climate protection and adaptation at the urban scale. Dr. Robert Thomann presented an AI-powered real-time microclimate model that creates a living digital picture of the city’s climate, enabling highly granular analysis and data-driven, climate-resilient urban planning.

The model integrates data from more than 500 sensors across Mannheim with high-resolution simulations, producing climate insights at a spatial resolution of up to 5 x 5 metres. This level of detail makes it possible to detect urban heat islands, analyse temperature differences between neighbourhoods, and understand how urban morphology, surface materials, vegetation, and shading influence local climate conditions throughout the day.

Beyond mapping and monitoring, the system functions as a practical decision-support tool for municipal action. Real-time and predictive analyses allow planners to assess heat exposure, identify climate risks for vulnerable populations, and evaluate the potential impact of adaptation measures such as tree planting, unsealing surfaces, or redesigning public spaces. By simulating different scenarios, the model supports evidence-based prioritisation and helps align climate strategies with concrete spatial interventions.

By embedding AI-driven climate intelligence into everyday urban governance, Smart City Mannheim demonstrates how digital tools can translate complex environmental data into actionable knowledge. The project illustrates a shift from reactive heat mitigation toward proactive, anticipatory climate adaptation, strengthening both urban resilience and public health in the face of increasing climate extremes.

This event is part of the ISCN Global Mixer, a series of events organized by the International Smart Cities Network. The presentations cover a wide range of topics related to international smart city approaches and provide exciting insights into urban digitalization worldwide - in just 30 minutes.
