Summary of results and recommendations derived in Workpackage 3 "Building energy performance" of the CENSE-project

The CENSE-project (2007-2010) was initiated by the European Commission to improve acceptance and use of the CEN-standards, which were developed to analyse the energy performance of buildings according to the EPBD. One of the project's major goals is to identify problems concerning the standards' content and their implementation via questionnaires and workshops and to formulate recommendations for improvement. Per cluster of standards on a specific subject technical recommendations have been prepared by the CENSE teams who focused on a specific subset of the CEN-EPBD standards. This report summarizes the results and recommendations on the cluster "Building Energy Performance", covering the CEN standards on lighting (EN 15193), energy use for heating and cooling (EN ISO 13790) and on thermal transmission (EN ISO 6946, 10077, 10211, 10456, 13370, 13786, 13789, 14683; EN 13947).
