Status on the Ground

Status on the Ground

While Member States are implementing the various building energy related directives (Energy Performance of Buildings Directive, Directive on the promotion of the use of energy from renewable sources, Energy Efficiency Directive) and paving the way towards Nearly Zero-Energy Buildings and a minimum share of Renewable Energy, indications emerge that the claimed energy performance can be different from reality. This may be jeopardising the reliability of and the trust in the Energy Performance Certificate (EPC) declarations and might in parallel influence the delivered quality of the works.

In this part of QUALICHeCK, the work focused on the collection of evidence regarding the energy performances in reality (“on the ground”):

  • What is the situation in practice as concerns easy access to reliable EPC input data, quality of the works and compliance frameworks?
  • Which are the critical situations?
  • What are interesting solutions or approaches for preventing such issues?

The aim has been to obtain a better understanding of the real situation regarding compliance and quality of the works influencing the energy efficiency of buildings and to identify bottlenecks as well as interesting best cases.

This includes obtaining better, well documented and structured information of the realised buildings in terms of EPC input data and quality of the works, including benchmarks, resulting in a better understanding of the market impact and, depending on the results, potential drivers for improved attention to compliance and quality, or supporting the attention paid to compliance and quality procedures.

In a first phase, maximum use has been made of existing surveys and field data, while in the second, evidence has been collected through new surveys and data collection activities namely in the 9 focus countries, targeting at least the 4 technology focus areas, as well as innovation.

This work allowed obtaining a clear picture of the status on the ground, with some surveys highlighting problematic situations, and others identifying a series of interesting cases which illustrate successful compliance approaches and/or large scale implementation of good quality of the works, contributing to better awareness.

This work has been led by the Tallinn University of Technology (TUT).
