This European Standard shall be given the status of a national standard, either by publicati

15、on of an identical text or by endorsement, at the latest by January 2008, and conflicting national standards shall be withdrawn at the latest by January 2008.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 European Free Trade Association (Mandate M/34

16、3), 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 buildings. An overview of the whole set of standard

17、s 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 of heating systems; methods for calculation

18、 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. they are based on requirements addressed to

19、 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 th

20、e 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 functiona

21、l 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 contradic

22、t with national regulations, the latter should be followed.

27、007 (E) 5 Introduction This European Standard constitutes the specific part related to building integrated photovoltaic systems, of the set of EN 15316 standards on methods for calculation of system energy requirements and system efficiencies of space heating systems and domestic hot water systems i

28、n buildings. This European Standard presents a method for calculation of the electricity production of building integrated photovoltaic systems. The calculation is based on the performance characteristics of the products given in product standards and on other characteristics required to evaluate th

29、e performance of the products as included in the system. The user needs to refer to other European Standards or to national documents for input data and detailed calculation procedures not provided by this European Standard. Only the calculation method and the accompanying input parameters are norma

30、tive. All values required to parameter the calculation method should be given in a national annex, containing appropriate national values corresponding to the tables given in Annex B. EN 15316-4-6:2007 (E) 6 1 Scope This European Standard is part of a set of standards on the method for calculation o

31、f system energy requirements and system efficiencies. The scope of this specific part is to standardise for photovoltaic systems: required inputs; calculation method; resulting outputs. The calculation method applies only to building integrated photovoltaic systems. The calculation method does not t

32、ake into account: electrical storage; PV/thermal photovoltaic systems. The calculation method describes how to calculate the electricity production of photovoltaic systems. Primary energy savings and CO2savings, which can be achieved by photovoltaic systems compared to other systems, are calculated

33、according to prEN 15603. Standards linked to photovoltaic systems are listed in Annex A. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition
