39、7988:2017CEN/TR 16798-8:2017 (E) 7 Introduction The set of EPB standards, Technical Reports and supporting tools In 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 doc

40、uments and tools are available: a) a document with basic principles to be followed in drafting EPB-standards: CEN/TS 16628, Energy Performance of Buildings 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 16

41、629, Energy Performance of Buildings Detailed Technical Rules for the set of EPB-standards 2; and 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

42、 for each Technical Report that accompanies an EPB standard or a cluster of EPB standards, including specific drafting instructions for the relevant clauses, and 3) a common template for the spreadsheet that accompanies each EPB standard, to demonstrate the correctness of the EPB calculation procedu

43、res. Each EPB standard 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 EPB-standards is to enable that laws and regulations directly refer to the EPB-standards and make compli

44、ance 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 account national and regional differences in climate, cul

45、ture 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 limitations of the EPB standards will be misunderstood, unless the

46、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, apply and nationally or regionally implement the EPB st

47、andards. 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, each EPB standard is accompanied by an informative Tec

48、hnical Report, like this one, where all informative content is collected, to ensure a clear separation between normative and informative contents (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;

49、 and to facilitate understanding of the set of EPB standards. PD CEN/TR 167988:2017CEN/TR 16798-8:2017 (E) 8 This was also one of the main recommendations from the European CENSE project 5 that laid the foundation for the preparation of the set of EPB standards.
