PD CEN/TR 15316-6-5:2017CEN/TR 15316-6-5:2017 (E) 5 Introduction The set of EPB standards, technical reports and supporting tools In order to facilitate the necessary ove

24、rall 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 Bu

25、ildings - Basic Principles for the set of EPB standards 2; 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 3; c) the detailed technical rules are the basi

26、s 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 that accompanies an EPB standard or a cluster of EPB standards, including specific drafting instructions for the re

27、levant 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, EN ISO 52000-1

28、4. 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 ener

29、gy 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 (An

30、nex 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, vari

31、ous 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, especial

32、ly 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 contents

33、(see CEN/TS 16629 3): to avoid flooding and confusing the actual normative part with informative content, PD CEN/TR 15316-6-5:2017CEN/TR 15316-6-5:2017 (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 main re

34、commendations from the European CENSE project 5 that laid the foundation for the preparation of the set of EPB standards.

Note 2 to entry: In the context of EN 15316-4-2, the bivalent temperature biv is adapted to the thermal load of the building a

40、nd is different from the EN 14825 conditions which means: 1) Input data consider temperatures, thermal capacities and COP based on the test conditions identified from EN 14825, 2) This EN 14825 bivalent temperature biv;ref,COPref and thermal capacity data is used as part of the EN 14825 dataset to i

41、nterpolate COP and capacity for each time step (operating condition) (using Path B) 3) EN 15316-4-2 determines a specific bivalent temperature for each time step (operating condition), which is different to the Manufacturer declared value (from EN 14825 data), to determine back-up requirement 4) Pra

42、ctically the bivalent temperature is a fixed value declared in the input data biv and use for control of the additional heating system when thermal capacity does not fulfill the thermal capacity required.
