A holistic methodology has been developed that is balancing economic and environmental performance of refurbishment scenarios and identifies Pareto optimal ones. The model allows to highlight individual measures in the dataset and therefore allow to assess their relative relevance. Social aspects can be taken into account in by linking scenarios with indicators like refurbishment time.
An excel-based software tool has been developed by ETH Zurich and Chalmers to support decision makers (building owners, investors, planers and policy makers) to identify the theoretical up-scaling potential of single energetic refurbishment measures on the national level. The tool has been used to provide rough estimates of the potential energy and Carbon dioxide savings of the refurbishment activities conducted in the BEEM-UP sites in France, the Netherlands and Sweden, assuming that these measurements would be applied to the entire building stock of these three countries. The potential energy and Carbon dioxide savings for space heat and domestic hot water are expressed as final energy, primary energy and CO²-equivalents.
The tool as well as a reference document will be available as download soon.
Challenges and opportunities to replicate the findings and solutions of the BEEM-UP project in Eastern Europe are different to those in the Western European countries. In cooperation with lead knowledge carriers in seven Eastern European countries a report has been generated to identify the main barriers and outlines potential solutions including the policy measures to be taken, and the impact they would have.
