An energetic analysis of a multifunctional façade system for energy efficient retrofitting of residential buildings in cold climates of Finland and Russia

Both in Finland and in Russia, the majorities of the apartment building stocks were built after the II World War. Major capital repairs are needed in both building stocks in the coming years. At the same time, energy efficiency of buildings could be improved which would make them more sustainable. The apartment building stocks in both countries consist of typical buildings of this construction period. Therefore prefabricated facade products, such as the “Meefs” system, could beneficially be adapted to retrofit them. In addition, as shown in this paper, the Meefs system would provide considerable energy savings. However, adapting the system to Russian buildings would require changes to building energy systems as well.
