10 European foreword This document (EN :2017) 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of an identical text or by endorsement, at the latest by December 2017, and conflicting national standards shall be withdrawn at the latest by December Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This standard has been produced to meet the requirements of Directive 2010/31/EU 19 May 2010 on the energy performance of buildings (recast), referred to as recast EPDB. This document supersedes EN 15242:2007. This document was produced to meet the requirements of Directive 2002/91/EC 16 December 2002 on energy performance of buildings referred to as EPBD. The revision for inclusion in the second mandate package was performed by CEN/ TC 156/ WG 21. The revision includes the following changes: rearrangement of content versus EN 15242:2007, in order to better fit in the modular structure given in EN ISO This document is restricted to emission and control of the ventilation air flow rates (M5-5); clarification of possibility to use 2 methods to calculate the airflow rates: method 1 based on detailed building characteristics; and method 2 using a statistical approach complying with specific rules; in method 1, addition of several options for the calculation of the airflow rates through windows, including cross-ventilation; in method 1, calculation of the airflow rates using mass balance only; formatting according to the new rules set in prcen/ts 16629; and consideration of ISO/TC 205 work performed in the meantime. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. 6
