The objective of this workshop was to discuss and identify ways to improve the quality of installed insulation systems as well as to (better) secure the compliance of product and system data, thereby increasing the confidence in declared values on the Energy Performance Certificate (EPC) and achieving the expected energy performance. Three aspects were more specifically addressed:

• how to improve the quality of the installation works;
• how to provide compliant input data used to issue an Energy Performance Certificate;
• how to enforce compliance, and how to define/apply penalties in case of non-compliance.

The workshop discussions were based on detailed presentations of schemes that are operational or under development. Interaction between participants will allow exchanges of ideas and experience.
