Small wooden dwellings, responsible for more than half of the total energy use in the Norwegian building stock. The project´s scope contributes significantly to the national target of 10 TWh/year energy saving by 2030 for existing buildings.

The project also created knowledge for nZEB level renovation of wooden dwellings for homeowners and builders, and knowledge for public and private decision makers on business models, regulations and incentives that can lead to market uptake of nZEB renovation towards 2030.
