Pilot Cities

  1. Trondheim
  2. Helsingborg
  3. Tudela
  4. Helsingør

The aim of the ECO-City project was to demonstrate innovative integrated supply and demand side energy concepts in three communities in Denmark/Sweden, Spain and Norway: respectively the cross-border community of Helsingør and Helsingborg, and the communities of Tudela and Trondheim.

Visualisation type: 

The following datasets is part of CONCERTO premium TMD and is provided as is. Note in certain cases the datasets are incomplete.

The values show the sum of New Buildings data + Refurbished Buildings data (including building integrated energy supply). The values do not contain data from Large Scale Energy Supply Units.


  • Reduced energy consumption in municipal buildings;
  • Increased investment in energy-saving equipment;
  • Information campaigns for schools and citizens, with one school applying energy efficient measures;
  • Training of janitors and caretakers;
  • Renovation of housing to a low-energy standard;
  • Construction of new low-energy housing;
  • The Helsingør district heating department installed a first biomass boiler and a second is planned;
  • Increased use of renewable energy, such as from biomass, wind, sun, soil, waste (biogas);
  • Following information meetings with decision-makers, the Helsingør City Council has applied for more subsidies for new similar projects.


  • Supply of environmentally friendly energy to St. Olavs Hospital (district heating and cooling through river water from Nidelev);
  • Efficient energy solutions for municipal schools - seasonal storage of waste as fuel for the incineration plant that supplies the district heating system;
  • Ecological rehabilitation and renewable energy supply for an ecological city district;
  • Construction of new low energy dwellings at “passive house” standard;
  • Individual metering and monitoring of electricity and heat consumption in block dwellings;
  • 21 of 53 public schools participated in an awareness raising campaign, which resulted in increased awareness of the project’s objectives and reduced consumption of energy;
  • 31 kindergartens applied the energy module;
  • 124 SME in Trondheim have finalised certification procedures and are environmental light-house certified;
  • Local politicians from the Climate Change Committee were informed about technical solutions and energy efficiency in buildings and have pushed for stricter energy standards for public buildings.


  • 26,460 m² of new and refurbished eco-dwellings:

- Queiles Eficiente: 122 new eco-dwellings (5 blocks); tertiary building (urban waste management);

- Lourdes Renove: 146 refurbished eco-dwellings (10 blocks); biomass district heating for 486 dwellings.

  • Renewable energy supply:

- 2.7 MW biomass boilers;

- 15.48 m² solar collectors for domestic hot water;

- 58m² photovoltaic panels;

  • High social impact: increased quality of life, wellbeing and health of inhabitants;
  • National and international recognition.
