Since 2016, the quarter has been involved in the Eureka Confluence programme. This confirms the role of La Confluence as a demonstration of a sustainable city.

Eurêka Confluence explained by its partners


  • Develop environmentally, economically and socially sustainable urban models with seven objectives:
    • low carbon footprint
    • energy autonomy
    • protection of water resources
    • preservation of biodiversity
    • functional and social diversity
    • participation by citizens 

>Reveal the regulatory barriers that hinder the development of sustainable city projects 


Eureka Confluence is an Industrial Demonstrator for the Sustainable City (DIVD), an inter-ministerial project launched in 2015 to promote the emergence of sustainable urban models that protect the environment and individuals and are economically viable without depending on public funding. The DIVD project an initiative promoted by the inter-ministerial agency PUCA (Plan for Urban design Construction and Architecture). It brings together the ministries of Ecological Transition and Territorial Cohesion to set up a national plan for the city of tomorrow, with public and private stakeholders. Eureka Confluence is based on a public/private partnership, and develops innovative urban projects in the fields of resource management, services and new uses, as well as health.


Eureka Confluence is led by Lyon Confluence, the developer of the urban project, and the property developer Bouygues Immobilier, in a consortium of more than 70 private and public structures. Among them:

This consortium is accompanied by an ethics committee composed of: 

The inhabitants and local associations are also stakeholders in Eureka Confluence.


The innovations are implemented throughout La Confluence, and more particularly on the A1 and A2 North "Sollys" blocks, whose total surface area (31,500 m2) is divided into:

  • 14,800 m2 of office space,
  • 200 housing units, of which 50% are open-market housing, 25% social housing, 25% intermediate and affordable housing, 
  • 2,600 m2 of shops, services and public facilities. 

The blocks are also divided into three categories: 

  • the active block hosts several services for mixed populations (residents and workers). 
  • the participatory block aims to create a block community as well as encouraging more environmentally friendly urban uses.
  • the health and well-being block targets the improvement of the quality of life of users 

The entire area has been designed to be energy positive and powered by renewable energy sources.

The creation of this new ecosystem requires the establishment of an "urban services operator," a platform to facilitate dialogue between all parties, measure the performance of new services, identify regulatory barriers and the appropriate policy levers, and inform users.

Eureka Confluence is developing soft mobility solutions in La Confluence as well as improving service. This involves optimising multimodal transport and deploying innovative modes of transport such as the Navly driverless shuttle. Sensors collect mobility data, providing real-time information on the solutions available to users.


Eureka Confluence is experimenting with a system for producing renewable energy and sharing it between several blocks and buildings. Solar panels and a cogeneration plant produce the energy to supply the buildings with electricity, heating and cooling. A network manages the pooling of consumption. This is complemented by a blockchain-based measuring and information system for residents, available on mobile phones. Objective: to consume locally produced renewable energy.


A modular and reversible building is being created alongside the A7 motorway as part of Eureka Confluence. The idea is for offices to be easily converted into housing and vice versa, to better adapt to the changing city and user needs. This flexibility is made possible by technologies that model the life cycle of the building.


A health and well-being area features in the programme, including prevention strategies, monitoring of chronic diseases and home care for the elderly. Residents will be able to take advantage of a therapeutic garden, a medical centre reserved for minor emergencies, a digital platform dedicated to local health care, and more.

Quality of life

Eureka Confluence is setting up a well-being indicator for the quarter by measuring the residents' exposure to environmental factors (air, noise, etc.). It will be based on environmental data and information related to the health of the residents. This indicator will make it possible to assess the impact of the area on its inhabitants.

Citizen involvement

The call for citizens' projects resulted in the emergence of 27 such projects. Two projects are now being launched following successful participatory fundraising campaigns:
