  21. 21. 16/09/2015 21 Conclusions Need to modernize buildings is evident only a few building types helps Major tecnical problems: Poor air tightness of structures No building-specific heat exchangers Lots of losses, especially in heating networks Plain building-specific analyses and renovations are not enough Remarkable potential for (especially heating) energy and water savings and reduction of emissions. The municipal solid waste is collected as mixed waste and the majority is landfilled. Both the infrastructure and the on-site sorting cultures are missing. More feasibly to renovate districts rather than just individual buildings
