Hybrid ventilation and daylighting in a Norwegian school building.

Several energy efficiency and renewable energy principles have been implemented in a recently refurbished and extended primary school building in Grong, Norway,. The building is located in the centre of Grong, a small town slightly north of Trondheim. The local authority's aim was to build an economical and modern school building with an attractive and healthy indoor environment and a minimal energy demand. In cooperation with the architect and the engineering consultants, SINTEF Architecture and Building Technology has developed solutions which utilise solar heat gains, daylight and natural forces for ventilation, both for comfort and energy-saving purposes.
