How to design the right mix An analysis of policy instruments addressing energy-efficient retrofitting of residential dwellings with a view to potential savings and barriers


Results of an analysis of policy instruments in Germany addressing retrofitting of single-family and semi-detached houses were presented. The analysis builds on an investigation of the barriers being responsible for the discrepancy between potential and actual refurbishment rates. Furthermore, the potential savings identified have been taken into account. Re-sults of this analysis show that the policy instruments currently in force do not adequately address the measures promis-ing the highest energy savings as well as the specific barriers of homeowners towards an energy efficient refurbishment. Drawing on these findings, recommendations for improving current policy instruments and implementing new instruments are given, focussing on the most promising types of buildings and refurbishment measures.
