Barriers for implementation
1. 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
