Building Performance
Directive Implementation Advisory Group

The (EU) European Energy Performance of Buildings Directive (EPBD) Directive Implementation Advisory Group (DIAG) was established in 2002 to advise the UK Government on the energy performance of buildings and the implementation of the European Energy Building Performance Directive.

The European Commission and Parliament are considering recasting the EPBD to introduce a number of key changes:-

  • DEC to be displayed in buildings larger than 250m² that are occupied by a public authority

  • EPC to be displayed in commercial buildings larger than 250m² that (a) are frequently visited by public and (b) where an EPC has previously been produced on the sale, rent or construction of that building

  • The energy performance of existing buildings of any size that undergoes major renovations to be upgraded in order to meet minimum energy performance requirements. Currently, there is a threshold of 1,000m²

  • Minimum energy performance requirements to be set in respect of technical building systems, e.g. boilers, air-conditioning units etc

  • Commission to establish common principles for definition of low and zero carbon (LZC) buildings. The definition of LZC to be determined by Member States but it must be in accordance with the principles set by the commission

  • Requirement to set targets for increase in LZC buildings with separate targets for:
    • new and refurbished dwellings
    • new and refurbished commercial buildings
    • buildings occupied by public authorities

  • Member States to aim for cost optimal levels of energy performance of their buildings using a methodology developed by the Commission

On the 19th May 2010 the European Parliament and Council published Directive 2010/31/EU containing amendments to the EPBD. The document can be  downloaded here.
