3、d This British Standard is the UK implementation of EN 15243:2007. With respect to the Energy Performance of Buildings Directive (EPBD) requirements, attention is drawn to the text of the fourth paragraph of the EN foreword. This recognizes at the present time that, if there is a conflict, existing
4、national regulations take precedence over any requirements set out in this standard. The UK participation in its preparation was entrusted to Technical Committee RHE/2, Ventilation for buildings, heating and hot water services. A list of organizations represented on this committee can be obtained on

41、43:2007 (E) 6 Foreword This document (EN 15243:2007) has been prepared by Technical Committee CEN/TC 156 “Ventilation for buildings”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by end
42、orsement, at the latest by February 2008, and conflicting national standards shall be withdrawn at the latest by February 2008. This standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association (Mandate M/343), and supports essential requ
43、irements of EU Directive 2002/91/EC on the energy performance of buildings (EPBD). It forms part of a series of standards aimed at European harmonisation of the methodology for the calculation of the energy performance of buildings. An overview of the whole set of standards is given in CEN/TR 15615,
44、 Explanation of the general relationship between various CEN standards and the Energy Performance of Buildings Directive (EPBD) (“Umbrella document“). Attention is drawn to the need for observance of EU Directives transposed into national legal requirements. Existing national regulations with or wit
45、hout reference to national standards, may restrict for the time being the implementation of the European Standards mentioned in this report. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held resp
46、onsible for identifying any or all such patent rights. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, Fran
