SMARTER TOGETHER (2016 - 2021)


This new European programme, developed in the district, aims to create innovative and sustainable energy solutions on a large scale.

Smarter Together


  • Develop urban models for sustainable energy


Smarter Together is a winner of the European research and innovation programme "Horizon 2020 - Smart Cities and Communities" launched by the European Commission in 2016.


Its budget is €30 million, including €7 million for the Lyon Confluence urban project. 


34 partners from 8 countries 

Smarter Together is a European consortium coordinated by SPL Lyon Confluence. It is made up of 34 partners from eight countries: cities (Lyon, Munich, Vienna, Santiago de Compostela, Sofia, Venice), industrialists, universities/research centres, consultants, associations, among others.

The Lyon team

  • Lyon Confluence
  • La Métropole de Lyon
  • Hespul (association specialising in the development of renewable energies and energy efficiency) 
  • L’ALEC-Lyon (Local Energy and Climate Agency of Métropole de Lyon) 
  • Enedis (national electricity grid operator)
  • Enertech (design office specialising in the energy performance of buildings)
  • La Régionale d’HLM de Lyon (social housing landlord)


Thanks to the European programme Smarter Together, several projects have been developed in the Lyon Confluence quarter:

  • commissioning of a district heating network powered by renewable energies,
  • doubling of the quarter's solar energy production (+1 MW),
  • energy renovation to reduce energy consumption and improve comfort in nine existing buildings (50,000 m2 in total): social housing, jointly-owned properties, offices, public facilities,
  • electric mobility:
    • 40 charge points,
    • 16 electric cars for car-sharing,
    • driverless electric shuttle. 
  • use of the Métropole de Lyon data platform to monitor and evaluate the district's energy performance. 

There are five objectives in collecting and analysing energy and mobility data from Lyon Confluence:
> check the compliance of new buildings to the specifications of Lyon Confluence,
> assess the energy performance of thermal renovation and use of buildings,
> provide information on the energy consumption of renovated housing units to residents upon request,
> monitor the energy consumption and production in La Confluence, as well as compliance with the zero-carbon objective of the Sustainable Action Plan,
> monitor the use of electric mobility systems.
Energy data (aggregated, not individual) are collected if owners give their permission. They are used, in the framework of evaluating the urban project, to improve the energy performance of buildings.


  • Thermal renovation enables older buildings to earn the BBC label (French low energy building certification) for energy performance: 96 kWh/m2/year of primary energy, equivalent to at least a 50% reduction of building consumption compared to pre-renovation levels. This represents an energy saving of 5,477 MWh per year and a reduction of more than 2,000 tonnes of CO2 per year, thus halving building emissions.
  • The implementation of a district heating network makes it easy to develop the consumption of renewable energy.
  • Increased local solar energy production. An additional 1 MW will be produced with five installations located on the Chanfray gymnasium, A3 and Ydéal, King Charles and H7 blocks to exceed 2 MW. Self-supply from solar energy production is being tested on H7 and Ydeal.
  • Experimenting with electric mobility services simplifies user travel and promotes sustainable development.
  • Increasing the involvement of citizens gives everyone the opportunity to participate in the design and life of the neighbourhood.
