Trondheim, Norway
Trondheim is a city and municipality in Sør-Trøndelag county situated by the Trondheim fjord. With a population of 173,486 it is the third most populous municipality and city in the country. This community has a very strong environmental engagement with strong research. It has an overachieving strategy with several goals that concerns energy and energy related issues; the first aim is that the municipality should contain the Kyoto-target for Norway within themselves.
A new state enterprise, Enova SF, was established in 2001 and has taken over responsibility for state efforts to promote energy savings and environmentally friendly forms of energy production (including renewable energy).
The CONCERTO approach
The project will set a reference for new standards to prevail in the community both in retrofitting, new buildings, energy supply and use polygeneration. Renewable energy supply comes from an area of 265 m² covered by solar collectors and 750 kW bio-mass fired boilers. Also, an energy conversion central with 3 MW absorption cooling and district heating systems based on waste sources are being applied.
Up to 350 new ECO-dwellings (22,400 m²) and ECO-rehabilitations of 24 dwellings (900 m²) will be realised, as well as ECO-rehabilitation of three schools in total 17,600 m², one commercial/cultural building of 3,000 m². The Nardo school is being reconstructed with new buildings built largely from wood, with external wood cladding and wood beams as a bearing structure. Heat losses will be minimised by high insulation values (insulation throughout of 30 cm thickness) and requirements on air tightness. A new hospital area of 94,000 m² out of 200,000 m² in total will also be constructed. A waste based district heating and bio-mass supply the eco-buildings together with the application of EE measures.
Use of Renewable Energy Sources
• Solar thermal energy
• Biomass heating
Low Carbon Technologies
• District heating,
• Reversible heat pump
• Insulation
• Mechanical ventilation with heat recovery
• Specific façade solutions
• Monitoring and targeting
• Glazing windows
Highlights
The Nardo school will feature a heat recovery ventilation system with 80 to 85 percent efficiency, an important factor as Norway has high standards for ventilation in schools. The school, in fact, is gaining recognition as a best practice case for educational establishments in Norway. A specific innovation is the intelligent metering in ECO-buildings.
