BS EN 15316-5:2017EN 15316-5:2017 (E) 6 Introduction This 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”. Al

37、l EPB standards follow specific rules to ensure overall consistency, unambiguity and transparency. 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 Ann

38、ex B with informative default choices. EPB standards deal with energy performance calculation and other related aspects (like system sizing) to provide the building services considered in the EPBD. This standard specifies two methods to take into account the energy performance of storage systems for

39、 heating of domestic hot water coupled to generation system(s) producing hot water or using independent energy input to the storage unit. This standard presents two methods applicable to the different technologies of water based storage system and related controls systems: method A applies when the

40、hot water is thermally stratified; method B applies when the hot water contained in the storage unit(s) is thermally homogeneous. The standard covers typically hourly time-step but can be adapted to different time steps accordingly with the scenarios used for energy use and energy delivered. The sub

41、jects 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 heating systems; methods for calculation of the design heat loss and heat loa

42、ds; methods for calculation of the energy performance of heating systems. For the correct use of this standard, Annex A is to be used to specify the choices with the required input data for use with method A (hourly calculation time step) or Method B (other calculation time steps). Default values fo

43、r use of the Method A and B monthly and annual methods are provided in Annex B. 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 applications, in particular for the application withi

44、n the context of EU Directives transposed into national legal requirements. These choices can be made available as National Annex or as separate (e.g. legal) document. It is expected, if the default values and choices in Annex A are not followed due to national regulations, policy or traditions, tha

45、t: either the national standardization body will consider the possibility to add or include a National Annex in agreement with the template of Annex A; or the national or regional authorities will, in the building regulations, reference the standard and prepare data sheets containing the national or

46、 regional choices and values, in agreement with the template of Annex A. Heating systems also include the effect of attached systems such as hot water production systems. BS EN 15316-5:2017EN 15316-5:2017 (E) 7 All these standards are systems standards, i.e. they are based on requirements addressed

47、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 complying with relevant product standards is no guarantee of compliance with t

48、he 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 describe ways to meet the requirements, but other ways to fulfil the function

49、al 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 individual needs may be accommodated. In cases where the standards contradict with national regulations, the latter should be followed.
