This European Stan

32、dard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2017, and conflicting national standards shall be withdrawn at the latest by November 2017. Attention is drawn to the possibility that some of the elements o

33、f this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 15241:2007. This document has been prepared under a mandate given to CEN by the European Commission and the European Free T

34、rade Association. Regarding the modifications that were made with regard to EN 15241:2007, these are listed in the last paragraph in the Introduction. This standard has been produced to meet the requirements of Directive 2010/31/EU 19 May 2010 on the energy performance of buildings (recast), referre

35、d to as “recast EPDB”. EN 15241:2007 was produced to meet the requirements of Directive 2002/91/EC 16 December 2002 on energy performance of buildings referred to as “EPBD”. For the convenience of Standards users CEN/TC 156, together with the responsible Working Group Convenors, have prepared a simp
