21、ed under a mandate 11 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 reports on the energy performance of buildings (the set of EPB standards).Attention is drawn to the possibility that some of

22、the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights.4PD CEN/TR 15378-2:2017CEN/TR 153782:2017 (E)IntroductionGeneralDirective 2010/31/EU recasting the Directive 2002/91/EC on energy performa

23、nce of buildings (EPBD, 11) 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 require

24、ments and cost effectiveness (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 ne

25、w and existing buildings. 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-rele

26、vant parts are replaced 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

27、 the comparison of 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 wil

28、l reduce costs compared to developing different standards at national level.The first mandate to CEN to develop a set of CEN EPBD standards (M 343, 8), to support the first edition of the EPBD (9) resulted in the successful publication of all EPBD related CEN standards in 2007-2008.The mandate M 480

29、 was issued to 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 inp

30、ut data that need 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 exp

31、anded 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.In case the EPB standards are used in the context of nation

32、al or regional legal requirements, mandatory choices may be given at national or regional level for such specific applications, in particular for the application within the context of EU Directives transposed into national legal requirements.Further target groups are users of the voluntary common Eu

33、ropean Union certification scheme for the energy performance of non-residential buildings (EPBD art.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.The set of EPB standards, t

34、echnical reports and supporting toolsIn order to facilitate the necessary overall consistency and coherence, in terminology, approach, input/output relations and formats, for the whole set of EPB-standards, the following documents and tools are available:a) a document with basic principles to be fol

35、lowed in drafting EPB-standards: CEN/TS 16628:2014, Energy Performance of Buildings - Basic Principles for the set of EPB standards 4;5PD CEN/TR 15378-2:2017CEN/TR 153782:2017 (E)b) a document with detailed technical rules to be followed in drafting EPB-standards; CEN/TS 16629:2014, Energy Performan

36、ce of Buildings - Detailed Technical Rules for the set of EPB-standards 5;c) the detailed technical rules are the basis for the following tools:1) a common template for each EPB-standard, including specific drafting instructions for the relevant clauses;2) a common template for each technical report

37、 that accompanies a EPB standard or a cluster of EPB standards, including specific drafting instructions for the relevant clauses;3) a common template for the spreadsheet that accompanies each EPB standard, to demonstrate the correctness of the EPB calculation procedures.Each EPB-standards follows t

38、he basic principles and the detailed technical rules and relates to the overarching EPB-standard, EN ISO 52000-1.One of the main purposes of the revision of the EPB-standards is to enable that laws and regulations directly refer to the EPB-standards and make compliance with them compulsory. This req

39、uires 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 account national and regional differences in climate, culture and building tradition, policy

40、 and legal frameworks (subsidiarity principle). For each option, an informative default option is provided (Annex B).Rationale behind the EPB technical reportsThere is a high risk that the purpose and limitations of the EPB standards will be misunderstood, unless the background and context to their

41、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, apply and nationally implement the EPB standards.If this explanation would have been at

42、tempted 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 each EPB standard is accompanied by an informative technical report, like this one, where all informati

43、ve content is collected, to ensure a clear separation between normative and informative contents (see CEN/TS 16629 5): to avoid flooding and confusing the actual normative part with informative content; to reduce the page count of the actual standard; and to facilitate understanding of the set of EP

44、B standards.This was also one of the main recommendations from the European CENSE project 9 that laid the foundation for the preparation of the set of EPB standards.This technical reportThis technical report accompanies the standard on the inspection of heating and domestic hot water systems.The fir

45、st part of this technical report, up to Clause 7 and all annexes up to Annex E have the same numbering as EN 15378-1. Each clause in this FprCEN/TR 15378-2 is related to the same clause in EN 15378-1.The role and the positioning of the accompanied standard(s) in the set of EPB standards is defined i

47、 this technical report and the accompanied standardThe first version of the standard on the inspection of boilers and heating system was issued in 2008 as part of the Mandate 343 of the EC to CEN to support the EPBD (2003).The standard has been completely redrafted as part of Mandate 480 of the EC t

48、o CEN.References in the text of the standard are given as module codes that are detailed in the annex. This enables flexible references (e.g. to national documents where necessary for local application) and use outside the CEN environment.7PD CEN/TR 15378-2:2017CEN/TR 153782:2017 (E)1 ScopeThis tech
