This European Standard shall be given the status of a national

21、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of an identical text or by endorsement, at the latest by January 2008, and conflicting national standards shall be withdrawn at the latest by January 2008.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 European Free Tr

22、ade 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 buildings. An overview

23、 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 of heating sys

24、tems; 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. they are based

25、 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 standards is no gu

26、arantee 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 requirements, but other

27、 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 accommodated. In cases

28、where the standards contradict with national regulations, the latter should be followed.

BS EN 15316-2-1:2007EN 15316-2-1:2007 (E) 6 Introduction This European Standard constitutes the specific part related to space heating emission, of the set of prEN 15316 standards on methods for calculation of system energy requirements and system efficiencies of s

34、pace heating systems and domestic hot water systems in buildings. This European Standard specifies the structure for calculation of the system energy losses and energy requirements of a heat emission system for meeting the building net energy demand. The calculation method is used for the following

35、applications: calculation of the system energy losses of the heat emission system; optimisation of the energy performance of a planned heat emission system, by applying the method to several possible options; assessing the effect of possible energy conservation measures on an existing heat emission

36、system, by calculation of the energy requirements with and without the energy conservation measure implemented. 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. BS EN 15316-2-1:2007

37、EN 15316-2-1:2007 (E) 7 1 Scope The scope of this European Standard is to standardise the required inputs, the outputs and the links (structure) of the calculation method in order to achieve a common European calculation method. The energy performance may be assessed either by values of the heat emi

38、ssion system efficiency or by values of the increased space temperatures due to heat emission system inefficiencies. The method is based on an analysis of the following characteristics of a space heating emission system, including control: non-uniform space temperature distribution; heat emitters em

39、bedded in the building structure; control accuracy of the indoor temperature. The energy required by the emission system is calculated separately for thermal energy and electrical energy, in order to facilitate determination of the final energy and subsequently the corresponding primary energy accor
