AI DATA DAY: Exploring the Future of Artificial Intelligence in Public Action
On 16 June 2026, Lille Metropole hosted the AI Data Day at Biotope, bringing together public sector professionals, researchers, businesses and innovation experts to explore how Artificial Intelligence is transforming local government. Through debates, demonstrations, workshops and immersive experiences, the event provided a unique opportunity to better understand the opportunities, challenges and practical applications of AI in public services.
From strategic discussions on governance and digital sovereignty to concrete demonstrations of AI-powered tools already deployed across the territory, the day highlighted the growing role of artificial intelligence in shaping the future of public action.
Understanding AI and Supporting Public Sector Transformation
The event opened with a strategic discussion on the place of AI within local authorities. Experts from the public and private sectors examined how municipalities can harness artificial intelligence to improve decision-making, optimise public services and support policy implementation, while addressing important questions related to ethics, governance and accountability.
AI in Action Across the Metropolitan Area
A central objective of the AI Data Day was to showcase concrete use cases already being developed both within Lille Metropole and beyond.
Participants discovered how AI is supporting geomatics and territorial analysis through the processing of aerial imagery, photographs and mobility data, helping public authorities better understand territorial dynamics and support planning decisions.
The event also provided an opportunity to engage with researchers from CRIStAL, one of Lille’s leading research centres in computer science and automation, whose work contributes to addressing many of the complex challenges faced by cities today, from resource management to mobility and service optimisation.
European Innovation for Positive Energy Districts
A European dimension was integrated in the programme through the presentation delivered by Vincent Demortier from the European network Open & Agile Smart Cities (OASC) of which Lille Metropole is member. Vincent Demortier shared insights from the Horizon Europe project exPEDite and its pilot Positive Energy District in Riga.
The project illustrates how artificial intelligence can support cities in managing the energy transition through practical and citizen-centred solutions. Machine learning models are being used to continuously forecast electricity production and consumption, helping optimise storage systems and grid management decisions.
One particularly innovative approach involves the integration of AI into “The exPEDition Game”, an interactive and gamified environment designed to help participants understand and manage Positive Energy Districts. Through a non-player AI character, users can receive personalised explanations and recommendations while exploring different scenarios and collective decisions.
This example demonstrated how AI can contribute not only to technical optimisation but also to strengthening citizen participation in complex urban transitions.
Imagining the Future of Public Services
Beyond current applications, the AI Data Day encouraged participants to reflect on the future impact of artificial intelligence on public sector professions.
An immersive exhibition invited visitors to imagine what public service jobs could look like in 2036, exploring scenarios where AI supports ecological transition, territorial resilience and citizen relations. Interactive workshops also enabled participants to better understand how AI systems are designed and trained.
The programme concluded with a public debate on a fundamental question: "Can AI truly serve the public interest ?" Discussions explored the balance between innovation, efficiency and democratic values, as well as the need to preserve public control over increasingly strategic digital technologies.
