PD CEN/TR 1531662:2017CEN/TR 15316-6-2:2017 (E) 5 Introduction This standard is part of a set of standards developed to support EPBD directive implementation, hereafter calle

29、d “EPB standards”. EPB standards deal with energy performance calculation and other related aspects (like system sizing) to provide the building services considered in the EPBD directive. CEN/TC 228 deals with heating systems in buildings. Subjects covered by CEN/TC 228 are: a) energy performance ca

30、lculation for heating systems; b) inspection of heating systems; c) design of heating systems; d) installation and commissioning of heating systems. The set of EPB standards, technical reports and supporting tools In order to facilitate the necessary overall consistency and coherence, in terminology

31、, 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 Buildings - Basic Principles for the set of EPB

32、standards 14; 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 15; c) the detailed technical rules are the basis for the following tools: 1) a common templa

33、te 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 relevant clauses; 3) a common template for the

34、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 16. One of the main purposes of the revision

35、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 energy performance procedures. The number of opt

36、ions 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 (Annex B). PD CEN/TR 1531662:2017CEN/TR 15316-6

37、-2:2017 (E) 6 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

38、, various 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, es

39、pecially 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 con

40、tents (see CEN/TS 16629 15): 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

41、 18 that laid the foundation for the preparation of the set of EPB standards. PD CEN/TR 1531662:2017CEN/TR 15316-6-2:2017 (E) 7 1 Scope This Technical Report refers to standard EN 15316-2. It contains information to support the correct understanding and use of EN 15316-2. The scope of this specific

42、part is to standardize the required inputs, the outputs and the links (structure) of the calculation method in order to achieve a common European calculation method. This standard covers energy performance calculation of heating systems and water based cooling space emission sub-systems. 2 Normative
