Lyon-Confluence urban project

Doubling the size of the Lyon city centre without increasing the greenhouse gas emissions

An initiative of Public company "SPL Lyon Confluence" (Société Publique Locale)

Overview of the project

France – Lyon-Confluence, sustainable neighbourhood

Since 2000 (until 2030), the development of the Lyon-Confluence urban project takes place in an area of 150 hectares (half existing neighborhood, half new construction and public spaces). In total, this represents the construction of an additional 1 million m2, without increasing the level of greenhouse gas emissions; thanks to:

  • the increase of local renewable energy production (photovoltaic & district heating)
  • the construction of new buildings with high energy performance (including positive energy blocks)
  • the energy renovation of the existing neighborhood (private groups of owners, social housing operators, office spaces, public facilities)
  • sustainable mobility
  • the development of a smart grid, via an energy data management platform.

Several international partnerships (Europe, Japan) contribute to make the Lyon-Confluence district a demonstrator for the sustainable development of Lyon Métropole.

Examples of partners working with the SPL Lyon Confluence :

  • Services of Lyon Métropole – Real estate developers (Bouygues Immobilier, Linkcity, Icade, OGIC, Vinci Immobilier, Cardinal…)
  • Industrial partners (Enedis, Toshiba, Dalkia, EDF, Schneider…)
  • Social housing operators (Grand Lyon Habitat, Lyon Métropole Habitat, Régionale d’HLM de Lyon, Rhône Saône Habitat…)
  • Private groups of owners – associations (Hespul…)
  • Consultancy companies (TRIBU, Enertech…)
  • Operators of electric mobility services (Navya, Keolis, CNR, Bluely…)
  • Inhabitants, workers and users of the neighbourhood
  • European Commission
  • Caisse des Dépôts (French financial institution)

Project Manager - Sustainable Development

To implement the Lyon-Confluence urban project, Lyon Métropole created an ad hoc company: the Local Public Company “SPL Lyon Confluence”. As urban developer of the neighborhood, the assignments of this company concern: urban planning studies, land control, new construction, renovation of the existing neighborhood, public spaces, consultation, information and communication.
