The overall research project was a Nordic collaboration between the following research partners: VTT in Finland, SINTEF in Norway, SBI in Denmark and KTH in Sweden. This report presents methods and concepts for building renovation and analyses the impacts of alternative renovation scenarios on Finnish building stock in terms of energy use and carbon footprint. The focus of the study is on residential buildings. The calculations were carried out for years 2010, 2020 and 2030. In addition to the assessment of the renovation concepts of building stock, the report also discusses and gives recommendations about the use of environmental data for energy sources, discusses and makes conclusions about the significance of building materials in renovation projects from the view point of greenhouse gases and total energy use, discusses and make recommen-dations about different renovations concepts, assesses and makes conclusions about the economic impacts of building renovation.
