No. EN ISO 13786:2017 EBS EN ISO 13786:2017EN ISO 13786:2017 (E) 2 European foreword This document (EN ISO 13786:2017) has been prepared
18、by Technical Committee ISO/TC 163 “Thermal performance 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
19、a national standard, either by publication of an identical text or by endorsement, at the latest by January 2018 and conflicting national standards shall be withdrawn at the latest by January 2018.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
20、 patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This document is part of the set of standards and accompanying technical r
21、eports on the energy performance of buildings and 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 (EP
22、BD, EF4) promotes the improvement of the energy 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 effe
23、ctiveness (Article 1). The directive requires Member 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 bui
24、ldings. One tool for this is the application by 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 rep
25、laced or retrofitted. Other tools are energy certification 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 o
26、f best practices and supporting the internal market 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 co
27、mpared to developing different standards at national 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
28、review the mandate M/343 as the recast of the EPBD 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, boundary conditions and input data that ne
29、ed to be defined at national or regional level. Such national or regional choices remain necessary, due to differences in climate, culture and building tradition, BS EN ISO 13786:2017EN ISO 13786:2017 (E) 3 policy and legal frameworks. Consequently, the set of CEN EPBD standards published in 2007-20
30、08 had to be improved and expanded on the basis 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 us
31、ers of the voluntary common European Union certification 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
32、 stock. This document supersedes EN ISO 13786:2007. 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, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland
