SCC 1 - 2015: Smart Cities and Communities solutions integrating energy, transport, ICT sectors through lighthouse (large scale demonstration - first of the kind) projects


The European lighthouse cities Vienna (Austria), Munich (Germany) and Lyon (France), the follower cities Santiago de Compostela (Spain), Sofia (Bulgaria) and Venice (Italy), the observer cities Kyiv (Ukraine) and Yokohama (Japan) came together to improve citizens’ quality of life. SMARTER TOGETHER prepared the ground for large-scale replication and ensured an in-depth knowledge transfer about setting up smart city business models and user-centric innovation in order to contribute to positive societal dynamics.

To deliver smart and inclusive solutions and to improve citizen’s quality of life SMARTER TOGETHER set out to find the right balance between smart technologies on one hand and organisational and governance dimensions on the other. While people ensure sustainability, industry - the necessary technology, governance ensures large-scale replication through its systematic approach and institutional learning.

The three lighthouse cities, all large and dynamic cities of similar size, focused on five concrete areas of co-created and replicable integrated smart solutions:

  • Living labs for citizen engagement
  • District heating and renewable energies for low energy districts
  • Holistic refurbishment for low energy districts addressing public as well as private housing
  • Smart Data management platform and smart services for integrated infrastructures
  • E-mobility solutions for sustainable mobility.

Best practice: Holistic refurbishment and retrofitting in Lyon, Munich, and Vienna

Cities of Lyon, Munich and Vienna took a holistic and integrative approach towards refurbishment and retrofitting of different housing types such as social housing, elementary schools, private housing estates with the added energy benefits in terms of installed photovoltaic panels, geothermal and heat pump solutions.

Cities focused on integrating solutions at the building level with the installation of local renewable energy solutions to be included in the refurbishment and renovation of buildings in their project portfolio. In Vienna, a a public building of the secondary school at Enkplatz 7 originally consisted of 8.800 m² floor area comprising 31 classes and 2 gymnasiums. The refurbishment considered an addition of new 7.300 m² constructed floor area for 13 new classes, 500m2 sports and relaxation area with an extensive roof greenery.

The most innovative aspect is the planning concept for the school that aimed to achieve a zero-energy building (ZEB) status where on an annual basis the energy consumption can be covered by local renewable sources. The building, however, remains connected to the electrical grid and to the district heating network in order to be energy flexible and resilient.

Impact and results:




  • Outperform European 2020 targets in large scale demonstration
  • Implement smart city business models, foster job creation and business acceleration
  • Actively pursue user-centric innovation
  • Establish a holistic low energy district approach
  • Develop flexible and reliable next generation district heating
  • Create citizen-oriented data platforms
  • Provide e-mobility solutions for various urban processes

Lyon, Munich and Vienna aimed to provide their citizens with:

  • more than 143.067 m2 of refurbished housing estate with an energy and CO2 reduction of  more than 50%
  • 17,2 MW of newly installed renewable capacity in the districts
  • 15 new e-mobility solutions saving 95,5 T/years of CO2
  • over 1500 created jobs
