Lighthouse City Solutions - Energy Efficiency


All three lighthouse cities have made great strides towards becoming more energy efficient. To this end, the cities have built new infrastructure and upgraded existing solutions – each more impressive than the next!

Vitoria-Gasteiz

  • Retrofitting
    As one of the city’s most vulnerable neighbourhood, the Coronación district saw a considerable number of residential buildings fully renovated, including their facades, insulation, windows and doors.
  •  Biomass district heating system
    In addition to the retrofitting activities, a biomass heating network was deployed in Vitoria-Gasteiz, leading to better energy prices, lower maintenance and operation costs and improved safety

Tartu

  • Retrofitting 
    The main idea of retrofitting activities in Tartu was to turn the Soviet-time “khrushchyovkas” into “smartovkas” buildings that offer an energy-efficient and high-quality living environment to the pilot area residents. 
  • District cooling station 
    A new district cooling system was installed in Tartu’s pilot area buildings involving a heat pump that produces heat for the district heating system by using residual heat from cooling.
  • LED lights with smart controllers
    A smart street light control system that is based on a wireless mesh technology is now installed in more than 320 new LED street lights in Tartu, including a number of detectors and sensors. 

Sonderborg

  • Retrofitting
    In Sonderborg, a total of 7 social housing departments will be fully retrofitted to reduce energy consumption, improve indoor climate and support Sonderborg in becoming a carbon-neutral city in 2029.  
  • Solar cells with battery storage in housing associations
    The combination of solar cell plants with a battery storage solution forms a reasonable alternative to feeding the produced electricity into the public grid.



Lighthouse City Solutions - Mobility


From biogas-fueled buses to electric bikes – the range of mobility actions in SmartEnCity is far and wide. Offering sustainable and environmentally conscious mobility options is key to building clean and healthy cities.

Vitoria-Gasteiz

Tartu

  •  Public bike sharing system
    As an additional mobility solution that the City of Tartu funded itself, an electric bike sharing system was set up, including 69 parking locations spanning across the entire city for maximum use and comfort.  
  • Gas buses in the whole city
    The City of Tartu has purchased 64 brand new biogas buses to serve the public transportation network – this is a major step towards the goal of making public transportation 100% based on gas in Tartu. 
  • Public EV rapid chargers 
    Five electric car rapid chargers were installed in the city center of Tartu to ensure the charging infrastructure of the city is diverse and accommodates all EVs.
  • Reusing old EV batteries
    Tartu has quite a large electric taxi fleet and seeks to repurpose these EV batteries by developing an energy storage solution that allows to partially recharge electric taxis with renewable energy that is produced on-site with PV panels.

Sonderborg

  • New biogas buses and biogas filling stations  
    As a zero-carbon mobility solution, 44 new energy-efficient buses fueled by biogas; improved digital services notifying users of departures etc. on apps and displays at major hubs; each of the new buses can carry 4 bikes on board, allowing a combined trip.
  • Public electrical vehicle charging points
    In total 31 EV chargers  have been installed in the Sonderborg area. The implementation of public electrical vehicle chargers not only increases the available infrastructure but also serves as a awareness raising point in the city.


Lighthouse City Solutions - ICT


ICT solutions not only help make life easier by providing simple, helpful data but they also play a crucial role in integrating all the smart systems of a city into a comprehensive whole.

Vitoria-Gasteiz

  • Urban management system
    The city platform developed in Vitoria-Gasteiz integrates all the existing ICT systems and enables to monitor the use of energy in the retrofitted buildings as well as to provide feedback to and get feedback from the citizens.  

Tartu

  • Smart home solution
    In addition to the retrofitting package that will see Tartu’s pilot area buildings fully renovated, the apartments will be supplied with a smart home system that connects to the Cumulocity cloud platform and enables data exchange and monitoring.
  • Tartu ICT platform 
    The aim of the platform is to collect and analyse city-wide data, both public and private, and to provide a user-friendly interface for any regular user who wishes to see real-time information about their city. The platform is also used to monitor the retrofitted pilot area, buses and bike sharing bikes, and much more.

Sonderborg

  • Sonderborg ICT Platform  
    Sonderborg's long term vision is to build a Digital Ecosystem for city data and services by integrating various data inputs and sensor systems together into one City ICT Platform, where anyone could add their own Value Services and ingetrate them into the provided city platform.
