29、ecretariat of which is held by DS. This 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of an identical text or by endorsement, at the latest by November 2008, and conflicting national standards shall be withdrawn at the latest by November 2008. Attention is

30、 drawn to the possibility that some of the 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 has been prepared under a mandate given to CEN by the European Commission and the Eu

31、ropean 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 building

32、s. An overview of the whole set of standards is given in CEN/TR 15615, Explanation of the general relationship between various CEN standards and the Energy Performance of Buildings Directive (EPBD) (“Umbrella document“). The subjects covered by CEN/TC 228 are the following: - design of heating syste

33、ms (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 loads; - methods for calculation of the energy performance of he

34、ating 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 the system as a whole and not dealing with requirements to the products within the system. Wher

35、e 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 the system requirements. The requirements are mainly expressed as functional requirements, i.e. re

36、quirements 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 functional requirements might be used if fulfilment can be proved. Heating systems differ among the membe

37、r 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. BS EN 15316-4-1:2008EN 15316-4-1:200

43、nts methods for calculation of the additional energy requirements of a heat generation system in order to meet the distribution and/or storage sub-system demand. The calculation is based on the performance characteristics of the products given in product standards and on other characteristics requir

44、ed to evaluate the performance of the products as included in the system. This method can be used for the following applications: judging compliance with regulations expressed in terms of energy targets; optimisation of the energy performance of a planned heat generation system, by applying the meth

45、od to several possible options; assessing the effect of possible energy conservation measures on an existing heat generation system, by calculating the energy use with and without the energy conservation measure. The user shall refer to other European Standards or to national documents for input dat

46、a and detailed calculation procedures not provided by this European Standard. BS EN 15316-4-1:2008EN 15316-4-1:2008 (E) 8 1 Scope This European Standard is part of a series of standards on the method for calculation of system energy requirements and system efficiencies of space heating systems and d

47、omestic hot water systems. The scope of this specific part is to standardise the: required inputs; calculation method; resulting outputs; for space heating generation by combustion sub-systems (boilers), including control. This European Standard is the general standard on generation by combustion su

48、b-systems (boilers). If a combustion generation sub-system is within the scope of another specific part of the EN 15316 series (i.e. part 4.x), the latter shall be used. EXAMPLE Biomass combustion generation sub-systems are within the scope of prEN 15316-4-7. This European Standard is also intended

49、for the case of generation for both domestic hot water production and space heating. The case of generation only for domestic hot water production is treated in EN 15316-3-3. 2 Normative references The following referenced documents are indispensable for the application of this document.
