Practical  experience shows that it is challenging to implement a robust compliance and enforcement framework for Energy Performance Certificates (EPCs) for buildings. The source book on EPC compliance aims to provide guidelines and suggestions for achieving such a framework.

This source book focuses on three key parts of such framework: first of all, one needs robust procedures for determining the input data used for calculating the EPC; then it is important to have a clear and robust legal framework for dealing with non-compliances of these input data and/or of the EPC; finally, there has to be implementation in practice.

In order to achieve a successful compliance and enforcement framework, it is crucial to take the local context into account. As such, the source book provides suggestions regarding choices to be made at country level, whereby societal support is crucial.
