Solbyn association is an eco-village that citizens built together through a tenant-owner association with a building company. It was initiated by a well educated, environmentally-concerned citizen group to create and live in an ecological village. The association is largely self-managing with support from HSB building company. Main activities are related to the realization of solar heating systems and energy efficiency projects. Solbyn association was founded in 1988 and today counts 50 households.
