17、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

18、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 Mem

19、ber 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 M

20、ember 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 cert

21、ification 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 marke

22、t 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 nation

23、al 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 EPBD

24、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 need to be defined at national or regional level. Suc

25、h 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 of the recast of the EPBD. The EPB standards ar

26、e 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 certification scheme for the energy performance of no

27、n-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.References: ISO 2017 All rights reserved iiiPD CEN ISO/TR 52019-2:2017ISO 52019-2:2017(E)

The work of preparing International Standards is normally carried out through ISO tech

International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely

33、 with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria need

40、ons and formats, for the whole set of EPB-standards, the following documents and tools are available:a) a document with basic principles to be followed in drafting EPB-standards:CEN/TS 16628:2014, Energy Performance of Buildings - Basic Principles for the set of EPB standards 8;b) a document with de

41、tailed technical rules to be followed in drafting EPB-standards;CEN/TS 16629:2014, Energy Performance of Buildings - Detailed Technical Rules for the set of EPB-standards 9.The detailed technical rules are the basis for the following tools:1) a common template for each EPB-standard, including specif

42、ic drafting instructions for therelevant clauses;2) a common template for each technical report that accompanies an EPB standard or a cluster of EPBstandards, including specific drafting instructions for the relevant clauses;3) a common template for the spreadsheet that accompanies each EPB standard

43、, to demonstrate thecorrectness of the EPB calculation procedures.Each EPB-standards follows the basic principles and the detailed technical rules and relates to the overarching EPB-standard, ISO 52000-1 5.One of the main purposes of the revision of the EPB-standards is to enable that laws and regul

44、ations directly refer to the EPB-standards and make compliance with them compulsory. This requires that the set of EPB-standards consists of a systematic, clear, comprehensive and unambiguous set of energy performance procedures. The number of options provided is kept as low as possible, taking into

45、 account national and regional differences in climate, culture and building tradition, policy and legal frameworks (subsidiarity principle). For each option, an informative default option is provided (Annex B).Rationale behind the EPB technical reports There is a risk that the purpose and limitation

46、s of the EPB standards will be misunderstood, unless the background and context to their contents and the thinking behind them is explained in some detail to readers of the standards. Consequently, various types of informative contents are recorded and made available for users to properly understand

47、, apply and nationally or regionally implement the EPB standards.If this explanation would have been attempted in the standards themselves, the result is likely to be confusing and cumbersome, especially if the standards are implemented or referenced in national or regional building codes.Therefore

48、each EPB standard is accompanied by an informative technical report, like this one, where all informative content is collected, to ensure a clear separation between normative and informative contents (see CEN/TS 16629 9): to avoid flooding and confusing the actual normative part with informative con

49、tent, to reduce the page count of the actual standard, and to facilitate understanding of the set of EPB standards.This was also one of the main recommendations from the European CENSE project5that laid the foundation for the preparation of the set of EPB standards.vi ISO 2017 All rights reservedPD CEN ISO/TR 52019-2:2017ISO 52019-2:2017(E)This document This technical report accompanies the suite of EPB standards on thermal transmission properties of building elements.
