Led by IES (Integrated Environmental Solutions), the Neighborhood Digital Twin (NeDT) is the simulation engine at the heart of the BLUEPRINT project. Unlike standard 3D city models that only show geometry, the NeDT is “physics-based.” It integrates real-time sensor data, weather files, and thermal properties of materials to simulate exactly how energy flows through the district.

This powerful tool enables technical experts and city planners to run precise “what-if” scenarios. For example, they can simulate the impact of insulating all roofs in a neighborhood, installing a district heating network, or adding solar panels. The NeDT instantly visualizes the results in terms of energy savings, carbon reduction, and even indoor comfort, de-risking the decision-making process before any physical work begins.
