23、6-8:2017 (E) 4 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 documents and tools are

24、 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 standards 1; b) a document with detailed technical rules to be followed in drafting EPB-standards; CEN/TS 16629:2014, Ene

25、rgy 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 drafting instructions for the relevant clauses; 2) a common template for each

26、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 spreadsheet that accompanies each EPB standard, to demonstrate the correctness of the EPB calculation procedures. Each EPB-

27、standards follows the basic principles and the detailed technical rules and relates to the overarching EPB-standard, EN ISO 52000-1:2017 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 compliance wit

28、h 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, culture and

29、 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 backgrou

30、nd 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 standards.

31、 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 technical r

32、eport, 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; and PD

33、CEN/TR 15316-6-8:2017CEN/TR 15316-6-8:2017 (E) 5 to facilitate understanding of the set of EPB standards. 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. PD CEN/TR 15316-6-8:2017CEN/TR 15316-6-8

40、tors 5.1 Output data The outcome of the calculation procedure is indicators that characterize a district energy system. The indicators are subdivided into two groups. Energy performance indicators reflect efficiency aspects as well as the source of the energy carrier. Energy source indicators dont r

41、eflect the efficiency aspects of the system but characterize the origin of the energy carrier. In 2012/27/EU Article 2 No. (41) efficiency and energy source are defined differently: “Efficient district heating and cooling means a district heating or cooling system using at least 50 % renewable energ

42、y, 50 % waste heat, 75 % cogenerated heat or 50 % of a combination of such energy and heat”. However EN 15316-4-5 does not set any efficiency requirements but provides the calculation procedures that facilitate compliance with requirements set by regulations like 2012/27/EU. RER, WHR and CHR can dir

43、ectly be used for this purpose. 5.2 Input data and calculation time step The vast majority of systems already exist so they should be assessed on the basis of measured energy data. Due to the many factors that can affect district energy systems, the indicators can fluctuate over time. For the purpos

44、e of building regulation a fluctuating energy indicator causes unwanted effects like unequal treatment of customers connected to the same system. This can be limited by basing the calculation on a broad range of data. Thus existing schemes shall be calculated using the energy data from the last thre

45、e years. If the system set-up or the fuel input mix has been changed within the last three years the calculation may be based on the energy data from a single year. Large systems supplying hundreds or even thousands of customers usually dont have the possibility to determine all input data on a mont

46、hly basis. Most energy indicators will therefore be valid for the whole year. In some special cases seasonal or monthly input data are required and available, e.g. in a trigeneration system where cooling is supplied by an absorption chiller that is supplied by a cogeneration unit. On an annual data

47、basis it would not be possible to divide the power bonus into a heating-related part and a cooling related part. Seasonal or monthly input data facilitate the determination of an accurate cooling performance indicator and a heating performance indicator. Another example is a small new system where e

48、ven the delivered energy is calculated on a monthly basis. In the determination of the final operating condition, the design conditions and manufacturing data the following developments may be taken into account: heat demand changes, changes in numbers of consumers, adaptations in generators and/or

49、energy carriers. PD CEN/TR 15316-6-8:2017CEN/TR 15316-6-8:2017 (E) 8 5.3 System boundaries If it is not possible or useful to calculate connected plants and networks together, they may be broken down into subsystems. This results in some subsystems which consume energy and others that supply energy. The energy from a supplier subsystem shall be assessed with its own energy indicators. For the consumer subsystem this is an external energy supply which is taken into account as an energy input with its specific energy indicator
