PD CEN/TR 153784:2017CEN/TR 15378-4:2017 (E) 6 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 an
35、d 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, Energy Performance of Buildings Basic Principles for the set of EPB standards 1; b) a document with detailed tec
36、hnical rules to be followed in drafting EPB-standards: CEN/TS 16629, 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 each EPB-standard, including specific draftin
37、g instructions for the relevant clauses; 2) a common template for each technical report 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 de
38、monstrate 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 52000-1:2017. One of the main purposes of the revision of the EPB-standards is to enable that laws and reg
39、ulations 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 in
40、to 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 high risk that the purpose and l
41、imitations 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 u
42、nderstand, apply and nationally 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 eac
43、h 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 2), to avoid flooding and confusing the actual normative part with informative conten
44、t, PD CEN/TR 153784:2017CEN/TR 15378-4:2017 (E) 7 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 4 that laid the foundation for the preparation of the set of E
45、PB standards. This Technical Report: This Technical Report accompanies the standard EN 15378-3:2017 on the assessment of measure measured delivered energy for space heating and domestic hot water preparation. The first part of this Technical Report, up to Clause 13 and all annexes up to Annex D have
46、 the same numbering as EN 15378-3:2017. Each clause in this CEN/TR 15378-4 is related to the same clause in EN 15378-3:2017. The role and the positioning of the accompanied standard(s) in the set of EPB standards is defined in the Introduction to the standard. Accompanying spreadsheet(s): Concerning
47、 the accompanied standard EN 15378-3:2017, the following spreadsheets were produced: one spreadsheet on space heating measured delivered energy assessment using the seasonal data interpolation method (see 6.8); one spreadsheet on space heating measured delivered energy assessment using the energy si
48、gnature method (see 6.9); one spreadsheet on domestic hot water measured delivered energy assessment; one spreadsheet on boiler efficiency assessment, both combustion efficiency and seasonal efficiency. In this Technical Report, two examples of space heating measured delivered energy assessment are
49、included. History of this Technical Report and the accompanied standard: EN 15378-3:2017 is the first edition of a standard on measured energy performance. It includes provisions already included in several previous standards like EN 15603:2008 (energy signature method) and EN 15378:2007 (measurement of combustion efficiency and estimation of boiler seasonal efficiency) and others. This Technical Report has been drafted as part of Mandate 480 of the EC to CEN. References in the text of the standard are given as mo
