SmartCityHub is a public platform for accelerating safe, sustainable, and scalable smart city innovation in Luxembourg by enabling cities and companies to experiment and validate AI solutions in real-life urban environments. It provides a secure environment where cities and companies can test AI before full deployment. SmartCityHub also connects municipalities from the Greater Region with European technology providers and researchers, fostering collaboration and innovation. This paper proposes a methodological framework for the co-design of Local Digital Twins (LDTs) based on an iterative and data-driven approach. It relies on the real-world deployment of an LDT with the city of Differdange, in the heart of the industrial basin in South Luxembourg, supporting its transition towards carbon neutrality. The paper identifies key challenges and derives practical lessons for developing scalable and interoperable LDTs in smart cities.
