26、echnical 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 available: a) a document with basic principles to be f

27、ollowed 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, Energy Performance of Buildings - Detailed Technical Rules

28、 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 technical report that accompanies an EPB standard or a

29、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-standards follows the basic principles and the detailed

30、 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 compliance with them compulsory. This requires that the set of EPB-standar

31、ds 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 building tradition, policy and legal frameworks (subsidiari

32、ty 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 background and context to their contents and the thinking behind the

33、m 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. If this explanation would have been attempted in the standa

34、rds 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 report, like this one, where all informative content is collec

35、ted, 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 to facilitate understanding of the set of EPB standards. This wa

36、s 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.

44、s The calculation of the thermal losses of pipes is well known and is used in this standard as a simplified model without any dynamic aspects like heat capacity of the pipes und changing of transfer coefficients. It is always taken into account that within a time step the heat flux from the mean wat

45、er temperature in the pipe to the surrounding room is constant. In closed circuits like for space heating and space cooling the mean supply and mean return temperature within a time step is constant. In open circuits like in domestic hot water systems with a circulation loop the open circuited stubs

46、 the temperature drops down depending on the time after a tapping. The calculation method in this standard allows calculating the temperature after the last tapping and then a mean temperature in this period without tapping. Because of the problem that the time after a tapping is mostly not known th

47、e calculation method in this standard allows calculating the mean temperature directly as an approximation depending on the thermal linear resistance. In domestic hot water systems without a circulation loop the thermal loss of the hot water pipes in total can be calculated like open circuited stubs

48、 either with the detailed calculation of the temperature after the last tapping or with the approximation of the mean temperature depending on the thermal linear resistance. As long as the tapping profile only gives the number of tappings per day it is not possible to determine the time after the la

49、st tapping. Therefore the approximation should prefer. The calculation of the thermal resistance for insulated or not insulated pipes is well known and is given in this standard for the most relevant cases. Depending on national regulations often minimum values of thermal resistances are postulated so that in the standard values for the most relevant cases in the pipe sections are given. The equations in the standard refer to the length of the pipes in the corresponding section of the network. If the length of the pipes is k
