No. EN ISO 10211:2017 EBS EN ISO 10211:2017EN ISO 10211:2017 (E) 2 European foreword This document (EN ISO 10211:2017) has been prepared by Technical Committee ISO/TC 163 “Thermal perf
18、ormance and energy use in the built environment“ in collaboration with Technical Committee CEN/TC 89 “Thermal performance of buildings and building components” the secretariat of which is held by SIS. This European Standard shall be given the status of a national standard, either by publication of a
19、n identical text or by endorsement, at the latest by January 2018 and conflicting national standards shall be withdrawn at the latest by January 2018. 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 responsib

This document is part of the set of standards and accompanying technical reports on the energy performance of buildings a
21、nd has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association (Mandate M/480, see reference EF3 below). Directive 2010/31/EU recasting the Directive 2002/91/EC on energy performance of buildings (EPBD, EF4) promotes the improvement of the energy
22、 performance of buildings within the European Union, taking into account all types of energy uses (heating, lighting, cooling, air conditioning, ventilation) and outdoor climatic and local conditions, as well as indoor climate requirements and cost effectiveness (Article 1). The directive requires M
23、ember States to adopt measures and tools to achieve the prudent and rational use of energy resources. In order to achieve those goals, the EPBD requires increasing energy efficiency and the enhanced use of renewable energies in both new and existing buildings. One tool for this is the application by
24、 Member States of minimum requirements on the energy performance of new buildings and for existing buildings that are subject to major renovation, as well as for minimum performance requirements for the building envelope if energy-relevant parts are replaced or retrofitted. Other tools are energy ce
25、rtification of buildings, inspection of boilers and air-conditioning systems. The use of European standards increases the accessibility, transparency and objectivity of the energy performance assessment in the Member States facilitating the comparison of best practices and supporting the internal ma
26、rket for construction products. The use of EPB standards for calculating energy performance, as well as for energy performance certification and the inspection of heating systems and boilers, ventilation and air-conditioning systems will reduce costs compared to developing different standards at nat
27、ional level. The first mandate to CEN to develop a set of CEN EPBD standards (M/343, EF1), to support the first edition of the EPBD (EF2) resulted in the successful publication of all EPBD related CEN standards in 2007-2008. Mandate M/480 was issued to review the mandate M/343 as the recast of the E
28、PBD raised the need to revisit the standards and reformulate and add standards so that they become on the one hand unambiguous and compatible, and on the other hand a clear and explicit overview of the choices, BS EN ISO 10211:2017EN ISO 10211:2017 (E) 3 boundary conditions and input data that need
29、to be defined at national or regional level. Such national or regional choices remain necessary, due to differences in climate, culture and building tradition, policy and legal frameworks. Consequently, the set of CEN EPBD standards published in 2007-2008 had to be improved and expanded on the basis
30、 of the recast of the EPBD. The EPB standards are flexible enough to allow for necessary national and regional differentiation and facilitate Member States implementation and the setting of requirements by the Member States. Further target groups are users of the voluntary common European Union cert
31、ification scheme for the energy performance of non-residential buildings (EPBD article 11.9) and any other regional (e.g. pan European) parties wanting to motivate their assumptions by classifying the building energy performance for a dedicated building stock. This document supersedes EN ISO 10211:2
