Very limited interest in and focus during planning on environmental effects and life-cycle economy Franz Freundorfer Helmut Krapmeier Dietmar Kraus 2. Lack of knowledge of potential. It is only becoming known that passive houses exist and generally reach the energy targets 3. Lack of knowledge of knowledge of how to reach the energy targets passivhausplaner.eu QuickTime™ and a decompressor are needed to see this picture.
