Securing the compliance of product data and the quality of installed systems to reach high levels of energy performance
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, with between participants allowing exchanges of ideas and experience.
Envelope systems contribute substantially to the thermal performance of the building.
National legislations implementing the European Directive on the Energy Performance of Buildings (EPBD) require a calculation of the energy performance, with an energy rating on the Energy Performance Certificate (EPC). This needs input data for the calculation to describe the building and the construction products, but also the performance of the systems. Input data must be compliant, i.e. determined according to the legal rules. It is also necessary that they can be found easily by the experts operating the calculation. In order to improve quality, the performance has also to be evaluated by on site measurements.
The trend towards Nearly Zero-Energy Buildings (NZEB) implies a better execution of construction works and the increased installation of advanced technologies, such as superinsulating materials, requiring specific skills of the workforce in order to reach quality and good performance of the installed systems.
