EPBD changes affecting Part L in 2013

DCLG has published the 2013 Amendments to Approved Documents for use with a number of current Approved Documents.

The changes listed in this document for Approved Documents L1a, L1B, L2A, L2B are made to take account of a recast of the European Energy Performance of Buildings Directive (Directive 2010/31/EU) with amended guidance for:

  • Energy Performance Certificates that comes into force on 9 January 2013; (all 4 ADLs)
  • the analysis of high efficiency alternative systems for new buildings occupied by public authorities on 9 January 2013 and for all other new buildings on 9 July 2013; (ADL1A and ADL2A)
  • the major renovation of existing buildings that comes into force for buildings occupied by public authorities on 9 January 2013 and for all buildings on 9 July 2013. (ADL1B and ADL2B)

The changes also take account of the introduction of a new Approved Document 7 that comes into effect on 1 July 2013, this has been updated to reflect the European Construction Products Regulation which will come fully into force on 1 July 2013. (common to all ADLs and other ADs)
