How the trade show has evolved

Trajectory analysis

EnerJ-meeting Lyon brings to the region the Paris format of EnerJ-meeting Paris: a single, dense day dedicated to the energy efficiency and decarbonisation of buildings. The 3rd Lyon edition (17 September 2024) brought together more than 1,600 decision-makers and 60 exhibitors at the Palais de la Bourse. No Lyon edition was held in 2025, as the regional calendar alternated between Paris (February) and Nantes (September) that year. The 2026 edition, on 15 September, aims for a clear step up with 2,000 decision-makers and 100 leading exhibitors announced. On the same territory and in the same sector, Lyon also hosts BePositive, the reference trade show for energy and environmental transitions. The 2026 figures cited are targets announced in advance, to be confirmed by the post-show report.
