This European Standard shall be given the status

23、 of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2008, and conflicting national standards shall be withdrawn at the latest by January 2008. This document has been prepared under a mandate given to CEN by the European Commission and the E

24、uropean Free Trade Association (Mandate M/343), and supports essential requirements of EU Directive 2002/91/EC on the energy performance of buildings (EPBD). It forms part of a series of standards aimed at European harmonisation of the methodology for calculation of the energy performance of buildin

25、gs. An overview of the whole set of standards is given in prCEN/TR 15615. 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

26、 of heating systems; 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 standards are systems standards, i.e.

27、 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 complying with relevant product sta

28、ndards 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 describe ways to meet the requirem

29、ents, 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 individual needs may be accommod

30、ated. In cases where the standards contradict with national regulations, the latter should be followed.

35、itzerland and United Kingdom. EN 15316-4-3:2007 (E) 6 Introduction This European Standard presents methods for calculation of the thermal solar system input for space heating and/or domestic hot water requirements and the thermal losses and auxiliary energy consumption of the thermal solar system. T

36、he calculation is based on the performance characteristics of the products given in product standards and on other characteristics required to evaluate the performance of the products as included in the system. This method can be used for the following applications: judging compliance with regulatio

37、ns expressed in terms of energy targets; optimisation of the energy performance of a planned heat generation system, by applying the method to several possible options; assessing the effect of possible energy conservation measures on an existing heat generation system, by calculating the energy use

38、with and without the energy conservation measure i.e. the energy savings of a thermal solar system is determined by the difference in the calculated energy performance of the building with and without the thermal solar system. The user needs to refer to other European Standards or to national docume

39、nts for input data and detailed calculation procedures not provided by this European Standard. EN 15316-4-3:2007 (E) 7 1 Scope This European Standard is part of a series of standards on the method for calculation of system energy requirements and system efficiencies. The framework for the calculatio

40、n is described in prEN 15603. The scope of this specific part is to standardise the: required inputs, calculation method, required outputs, for thermal solar systems (including control) for space heating, domestic hot water production and the combination of both. The following typical thermal solar

41、systems are considered: domestic hot water systems characterized by EN 12976 (factory made) or ENV 12977 (custom built); combisystems (for domestic hot water and space heating) characterized by ENV 12977 or the Direct Characterisation method developed in Task 26 Solar Combisystems of the IEA Solar H

42、eating and Cooling programme; space heating systems characterized by ENV 12977. 2 Normative references The following referenced documents are indispensable for the application of this document.

49、oses (e.g. space heating and domestic hot water) it can be difficult to split the energy use into that used for each purpose. It can be indicated as a combined quantity (e.g. energy use for space heating and domestic hot water). NOTE 2 The heat use for space heating and/or domestic hot water is the sum of the energy needs and the system thermal losses of the space heating system and/or the domestic hot water system minus the recovered system thermal losses at the system boundary. 3.7 recoverable system thermal loss part of the
