28、316-6-1:2017 (E) 5 Introduction The CENSE project, the discussions between CEN and the Concerted action highlighted the high page count of the entire package due to a lot of “textbook” information. This resulted in flooding and confusing the normative text. In order to facilitate the necessary overa

29、ll 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 followed in drafting EPB-standards: CEN/TS 16628:2014, Energy Performance of Buil

30、dings - Basic Principles for the set of EPB standards 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 f

31、or 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 that accompanies an EPB standard or a cluster of EPB standards, including specific drafting instructions for the relev

32、ant 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 the basic principles and the detailed technical rules and relates to the overarching EPB-standard, prEN ISO 52000-1:2

33、015. 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 requires that the set of EPB-standards consists of a systematic, clear, comprehensive and unambiguous set of en

34、ergy 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 and legal frameworks (subsidiarity principle). For each option, an informative default option is provided (

35、Annex B). Rationale behind the EPB technical reports 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, va

36、rious types of informative contents are recorded and 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, especi

37、ally 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 informative content is collected, to ensure a clear separation between normative and informative content

38、s (see CEN/TS 16629): - to avoid flooding and confusing the actual normative part with informative content, PD CEN/TR 15316-6-1:2017CEN/TR 15316-6-1:2017 (E) 6 - 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 m

39、ain recommendations from the European CENSE project 1 that laid the foundation for the preparation of the set of EPB standards. Figure 1 shows the relative position of the related standard within the EPB package of standards and the position of all the other EPB standards under the responsibility of
