The Energy Performance of Buildings Directive recast gives ambitious goals for the building sector to reduce energy use as well as greenhouse gas emissions. It requires member states to engage in the generalization of Nearly Zero-Energy Buildings and to set up the necessary actions to support the mandatory availability of Energy Performance Certificates (EPC), both for new and existing buildings.

The objectives of this webinar were:

• to show several issues on the quality of the EPC input data or the quality of the works that can be detrimental to achieve compliance in practice;
• to present preliminary results of field studies to evaluate initiatives addressing two of those issues.
