Lyon is one of the lighthouse cities in the SMARTER TOGETHER project. The demonstration area in focus is Lyon-Confluence, one of the largest urban redevelopment projects in France (150 ha – 600 000 m² existing floor area – 1 million m² of new buildings) and an area of many urban innovations. With SMARTER TOGETHER, Lyon-Confluence heads towards zero-carbon objectives, which means that after the implementation phase the annual greenhouse gases emissions of the buildings must not be superior to the level of emissions at the beginning of the project, despite an increase in built area (1 000 000 m² of new constructions), population and activities in the area.

* Detailed information regarding the technical and financial performance will be available at a later stage.

With SMARTER TOGETHER, Lyon aims to:

  • refurbish 35 000 m2 of existing buildings to reduce their energy consumption;
  • develop local renewable energy generation: photovoltaic systems (1 MWp) and a wood-fired cogeneration power plant (2 MWe/4 MWth);
  • reduce the use of conventional cars by providing alternative means of transport for inhabitants: smart charging stands, an electric vehicle car-sharing system and an autonomous driverless electric shuttle;
  • feed the existing Grand Lyon smart data platform with news set of data to better monitor energy production and consumption in the area, and the actual effects and benefits of measures implemented to reach the zero-carbon objective;
  • involve citizens in the redevelopment of the Lyon Confluence area and the implementation of new services (creation of an urban living lab to allow citizens and users to co-design the smart city solutions);
  • increase the inhabitants’ quality of life through the construction of comfortable and affordable dwellings and offices, convenient public spaces, easy access to the district, etc.

The project in Lyon-Confluence is a complex endeavour, involving numerous players. One of the specificities is that the refurbishment targets mostly jointly privately owned buildings in a low income area and with high expectations regarding renewable energy sources, energy efficiency and data sets collected to better monitor the energy performance.

The high level of complexity of the Lyon-Confluence urban project required a proper and skilful management team to successfully conduct and oversee the different dimensions, such as consent from owners and tenants, price competitiveness of renewable energy sources, regulatory issues (tenders which can delay the project), technical capabilities of the joint owners, connection of the building with the fully renewable district heating, quality and availability of the data sets needed for a better energy management of the district, behaviour, cooperation between the public departments, etc.

There is not a one-stop shop solution but a steady process combining a clear long term vision and commitment of resources with short-term and pragmatic actions. The quality of the team and its expertise is a key factor of success to mobilise the complex district ecosystem.

The refurbishment of the buildings takes place in an area with strong constraints due to heritage protection. This impacts the type of works that are authorized with respect to the appearance of the buildings (external insulation, change of windows, etc.) and can also increase the cost of the eco refurbishment.

The solution is that part of the team works closely with the public authorities in charge of heritage protection, and the design of the project features a proper balance between energy performance, cost and protection of the heritage.

Renewable energy sources competitiveness, despite serious improvements, is still not achieved.

Lyon-Confluence has an important goal to achieve 1 MWp in photovoltaics. In order to make this happen given the current French regulation system, the local public redevelopment company SPL Lyon-Confluence obtained a feed-in tariff within national auctions.

Early inclusion of owners and tenants in the refurbishment works is essential. Refurbishment of social housing is far easier as there are competences and processes in place - consultation, tender, schedule, building site. It is far more complex with joint owners, who often don’t have the necessary expertise to undertake large scale building works.

Some of the solutions are to mobilise part of the team to work closely with the owners and tenants, to add financial incentives for the refurbishment in exchange for the connection to the fully renewable district heating which is currently being completed.

Including citizens in the early stages of development is key and is carried out through variety of actions – setting up the so called House of the project, organising labs, providing the opportunity to participate in the prototyping. On one hand, this focuses on the involvement of local inhabitants (private groups of owners) in the eco refurbishment of their buildings. On the other, the inhabitants and the people working in the neighbourhood are engaged in the management of their energy consumption by means of data collection.

As this is a lighthouse project, scale is important and given the short timeline the ability to shift rapidly the refurbishing works from one building to another is crucial.

France

The project team encountered challenges with the access, collection and use of data from multiple public and private providers. For example, in order to assess the actual energy performance of buildings - either recently built or refurbished – the team had to secure access to data and complying with the data privacy regulations was a must.

France

Costs for IT development and maintenance with respect to collection, storage and use of data (public and private providers of data, city data platform, tool for data visulation and analysis) need to be taken into account in order to easily replicate the pilot action of SMARTER TOGETHER at a larger scale, in particular in the rest of Lyon Metropolis area.

Some measures to be implemented in Lyon-Confluence within the SMARTER TOGETHER project are:

Energy efficiency in buildings

  • Retrofitting the building envelope
    • Reducing energy consumption by refurbishing an area of 35 000 m2 of existing buildings (private housing, social housing, office spaces and public buildings)

Energy systems integration

  • District heating and cooling
    • Renewable district heating
  • Cogeneration (CHP)
    • SMARTER TOGETHER includes the construction of a wood-gas fired cogeneration power plant of 2 MWe/4 MWth, connected to the district heating
  • Photovoltaics (PV)
    • Four photovoltaic systems are constructed to achieve a total power of approximately 1 MWp, which comes in addition to the 1 MWp of photovoltaic systems already existing in the Lyon-Confluence area.
Mobility & transport: 
  • Clean fuels and fuelling infrastructure
    • Smart charging stands
  • Electric, hybrid and clean vehicles
    • Autonomous driverless electric shuttle
  • Car sharing
    • Electric vehicle car-sharing system
ICT: 
  • Building energy management system
  • Neighbourhood energy management system
  • Urban data platform
    • Provision of new sets of dynamic data to the Grand-Lyon data platform from the energy and sustainable mobility sector collected from various sources – smart power and heat meters, building energy management system, shared electric mobility services, energy production systems in the area, such as photovoltaic systems, and the district heating power plant plant - in order to monitor energy generation and consumption in the area and assess the actual energy performance of buildings
