QUALICHeCK project final publishable report



The Energy Performance of Buildings Directive of 2002 and its recast in 2010 have been key elements urging EU Member States to drastically reduce the energy use in buildings and pave the route towards Nearly-Zero Energy Buildings.


Building’s Energy Performance Certificates (EPCs) are probably the most visible symbol showing the way forward as they are meant to inform prospective buyers and tenants to encourage them to invest in energy efficiency in buildings. Nevertheless, insufficient quality assurance measures could jeopardize these policy efforts. More specifically, frequent deviations between actual versus claimed or expected EPC ratings and quality of building works could discredit the overall approach to energy conservation in the building sector.


The IEE QUALICHeCK project’s goal was to avoid this pitfall by raising awareness and triggering initiatives to improve the compliance of Energy Performance Certificates and the quality of buildings works. This goal entailed 3 specific objectives:


  • To confirm the concern for non-compliant EPCs and quality of buildings works, based on a literature review and 10 specific field studies in 9 countries, each on samples of 25+ buildings.
  • To show the benefits of existing approaches with the analysis of over 30 examples developed to contain non-compliance of EPCs and building works.
  • To give the key steps to set up compliance frameworks, including a summary of key issues that should be addressed for a sound foundation of a compliance framework.

This booklet summarises the key findings of QUALICHeCK structured around these 3 specific objectives. Overall, the non-compliance rates or the numerous quality of the works problems reported in QUALICHeCK and outlined herein demonstrate that the concern for the compliance of EPCs and building works has been superficial in many member states. On the other hand, there exist a number of successful approaches to contain non-compliance that could inspire for member states, although these approaches may be limited in scope or impact.
