The project Trondheim community, Norway

The City of Trondheim.


Trondheim's municipal climate action plan
- Reduce greenhouse gas emissions by 20% from 1999 levels by 2010
  • Objective related to stationary energy consumption:

  •       - Increase the amount of renewable sources in the energy
          - Reduce energy demand by improved energy efficiency
          - Sustainable utilization of local resources for energy

  • This shall be accomplished through:

  •       - Municipal energy planning & active use of legislation
          - Implementation of energy conservation initiatives
          - Giving priority to sustainable use of renewable energy
          - District heating supply in all parts of the city

    Trondheim holds a special place in Norwegian history and culture. It was the first capital of Norway, and is still the city where new kings receive their ceremonial blessing. The city is situated by the Trondheim fjord, it is surrounded by forested hills, with the Nidelva river winding through the town.

    The ECO-City city demonstration sites in Trondheim comprise a whole integrated community approach and demand side.

    The community participants include the main actors in town planning, city development and energy infrastructure, including the municipality of Trondheim, the utility of Trondheim, the building company of heimdalgruppen, TOBB, Stiftelsen Svartlamoen, SINTEF and the consulting company COWI Norway.

    The concerto project will set a reference for new standards to prevail in the community both in retrofitting, new buildings, energy supply and use polygeneration. The new intelligent metering to be tested is expected to form the future standard to be used in the community. Also the approach will be anchored in the whole community through training of SME's and schools and through extensive dissemination.
