Attention is

30、drawn to the possibility that some of 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. This document has been prepared under a mandate given to CEN by the European Commission and the Eur

31、opean Free Trade Association. PD CEN/TR 1531664:2017CEN/TR 15316-6-4:2017 (E) 5 Introduction This document informs about EN 15316-4-1 as a part of a series of standards aimed at European harmonization of the methodology for the calculation of the energy performance of buildings. A huge amount of inf

32、ormative contents needs indeed to be recorded and made available for users to properly understand, apply and nationally adapt the EPB standards. The set of EPB standards, Technical Reports and supporting tools In order to facilitate the necessary overall consistency and coherence, in terminology, ap

33、proach, 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 followed in drafting EPB-standards: CEN/TS 16628:2014, Energy Performance of Buildings - Basic Principles for the set of EPB stan

34、dards 1; b) a document with detailed 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 2; c) the detailed technical rules are the basis for the following tools: 1) a common template for

35、 each EPB-standard, including specific drafting instructions for the relevant clauses; 2) a common template for each technical report that accompanies an EPB standard or a cluster of EPB standards, including specific drafting instructions for the relevant clauses; 3) a common template for the spread

36、sheet that accompanies each EPB standard, to demonstrate the correctness of the EPB calculation procedures. Each EPB-standards follows the basic principles and the detailed technical rules and relates to the overarching EPB-standard, EN ISO 52000-1 3. One of the main purposes of the revision of the

37、EPB-standards is to enable that laws and regulations 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 pr

38、ovided is kept as low as possible, taking into 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

39、There is a risk that the purpose and limitations 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

40、made available for users to properly understand, 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 i

41、n national or regional building codes. PD CEN/TR 1531664:2017CEN/TR 15316-6-4:2017 (E) 6 Therefore, 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

42、(see CEN/TS 16629 2): 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 EPB standards. This was also one of the main recommendations from the European CENSE project 5 that

43、 laid the foundation for the preparation of the set of EPB standards. EN 15316-4-1 is intended to replace EN 15316-4-1:2008 and includes Domestic hot water systems, generation (former EN 15316-3-3) and biomass boilers (former EN 15316-4-7:2008) in this standard published in 2007-2008 under the manda

44、te M/343 on the EPBD. This revision was required as a result of the EPBD recast (2010/31/EU).The set of standards developed under mandate M/343 will be revised to become consistent with the overarching standard under mandate M/480. The typology method has been removed, the boiler cycling method has

45、been added for existing boilers to get the input parameters for the case specific boiler efficiency method. Other generation systems are covered in other sub modules of part M3-8 (see Figure 1).
