This document has been published by the Minister for the Environment, Heritage and Local Government under article 7 of the Building Regulations 1997.

It provides guidance in relation to Part L of the Second Schedule to the Regulations as inserted by Building Regulations (Part L Amendment) Regulations 2008 (S.I. No. 259 of 2008). The guidance in this document applies to buildings other than dwellings. These Regulations (and this document) partly transpose the EU Energy Performance of Buildings Directive - EPBD (2002/91/EC of 16 December 2002).

The document should be read in conjunction with the Building Regulations 1997-2005 and other documents published under these Regulations. In general, Building Regulations apply to the construction of new buildings and to extensions and material alterations to existing buildings. In addition, certain parts of the Regulations apply to existing buildings where a material change of use takes place. (Otherwise, Building Regulations do not apply to buildings constructed prior to 1 June 1992).
