16、s European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2017 and conflicting national standards shall be withdrawn at the latest by November 2017.Attention is drawn to the possibility that some of t

17、he elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights.This document supersedes EN 15316-4-5:2007 .This document has been prepared under a mandate given to CEN by the European Commission and the

18、 European Free Trade Association.The revision keeps the main principles of the calculation unchanged but the structure of the document was changed. Informative content was removed to the accompanying Technical Report CEN/TR 15316-6-8. The provisions cover also other energy carriers than heat now.For

19、 the calculation of cogeneration units additional methods have been introduced so specific electricity values can be calculated if required.Calculation methods to determine energy source indicators like the renewable energy ratio have been added.The main changes compared to EN 15316-4-5:2007 are:a)

20、informative content was removed to the accompanying Technical Report CEN/TR 15316-6-8;b) provisions now also cover other energy carriers than heat;c) Annex B contains a set of default values for energy flows and carriers that are specific for district heating systems and are thus not covered by the

21、building specific standards.According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republ

22、ic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.3BS EN 15316-4-5:2017EN 15316-4-5:2017 (E)Introducti

23、onThis European Standard is part of a series of standards aiming at international harmonization of the methodology for the assessment of the energy performance of buildings, called “set of EPB standards”.All EPB standards follow specific rules to ensure overall consistency, unambiguity and transpare

24、ncy.All EPB standards provide a certain flexibility with regard to the methods, the required input data and references to other EPB standards, by the introduction of a normative template in Annex A and Annex B with informative default choices.For the correct use of this standard a normative template

25、 is given in Annex A to specify these choices. Informative default choices are provided in Annex B.Use by or for regulators: In case the standard is used in the context of national or regional legal requirements, mandatory choices may be given at national or regional level for such specific applicat

26、ions. These choices (either the informative default choices from Annex B or choices adapted to national / regional needs, but in any case following the template of this Annex A) can be made available as national annex or as separate (e.g. legal) document (national data sheet).NOTE So in this case: t

27、he regulators will specify the choices; the individual user will apply the standard to assess the energy performance of a building, and thereby use the choices made by the regulators.Topics addressed in this standard can be subject to public regulation. Public regulation on the same topics can overr

28、ide the default values in Annex B of this standard. Public regulation on the same topics can even, for certain applications, override the use of this standard. Legal requirements and choices are in general not published in standards but in legal documents. In order to avoid double publications and d

29、ifficult updating of double documents, a national annex may refer to the legal texts where national choices have been made by public authorities. Different national annexes or national data sheets are possible, for different applications.It is expected, if the default values, choices and references

30、to other EPB standards in Annex B are not followed due to national regulations, policy or traditions, that: national or regional authorities prepare data sheets containing the choices and national or regional values, according to the model in Annex A. In this case the national annex (e.g. NA) refers

31、 to this text; or, by default, the national standards body will consider the possibility to add or include a national annex in agreement with the template of Annex A, in accordance to the legal documents that give national or regional values and choices.Further target groups are parties wanting to m

32、otivate their assumptions by classifying the building energy performance for a dedicated building stock.More information is provided in the Technical Report accompanying this standard (CEN/TR 15316-6-8).EPB set of standards deal with energy performance calculation and other related aspects (like sys

33、tem sizing) to provide the building services considered in the EPBD.The subjects covered by CEN/TC 228 are the following: design of heating systems (water based, electrical, etc.); installation of heating systems; commissioning of heating systems; instructions for operation, maintenance and use of h

34、eating systems;4BS EN 15316-4-5:2017EN 15316-4-5:2017 (E) methods for calculation of the design heat loss and heat loads; methods for calculation of the energy performance of heating systems.Heating systems also include the effect of attached systems such as hot water production systems.All these st

35、andards are systems standards, i.e. they are based on requirements addressed to the system as a whole and not dealing with requirements to the products within the system.Where possible, reference is made to other European or International Standards, a.o. product standards. However, use of products c

36、omplying with relevant product standards is no guarantee of compliance with the system requirements.The requirements are mainly expressed as functional requirements, i.e. requirements dealing with the function of the system and not specifying shape, material, dimensions or the like.The guidelines de

37、scribe ways to meet the requirements, but other ways to fulfil the functional requirements might be used if fulfilment can be proved.Heating systems differ among the member countries due to climate, traditions and national regulations. In some cases requirements are given as classes so national or i

38、ndividual needs may be accommodated.In cases where the standards contradict with national regulations, the latter should be followed.This European Standard specifies the calculation of indicators that characterize district energy systems. The majority of district energy systems in Europe are distric

39、t heating systems, but the basic principles will also be applied on other energy carriers, e.g. district cooling. The indicators are required for the calculation of the energy performance of buildings that are connected to district energy systems.This European Standard was developed during the first

40、 EPBD mandate and the first version was published in 2007.5BS EN 15316-4-5:2017EN 15316-4-5:2017 (E)1 ScopeThis European Standard defines the determination of energy indicators of district energy systems. District energy systems may be district heating, district cooling or other district energy carr

41、iers.Table 1 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in EN ISO 52000-1.NOTE 1 In CEN ISO/TR 52000-2 the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying t

42、echnical reports that are published or in preparation.NOTE 2 The modules represent EPB standards, although one EPB standard may cover more than one module and one module may be covered by more than one EPB standard, for instance a standard may cover a simplified and a detailed method respectively.
