18、s” , the secretariat 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of an identical text or by endorsement, at the latest by January 2008, and conflicting national standards shall be withdrawn at the latest by January 2008. This

19、 document has been prepared under a mandate given to CEN by the European Commission and the European 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 E

20、uropean harmonisation of the methodology for calculation of the energy performance of buildings. 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 heati

21、ng 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 heating systems. Heating systems also include the effect of attached

22、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. Where possible, reference is made to other European or International St

23、andards, 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. requirements dealing with the function of the system and not specifyi

24、ng 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 member countries due to climate, traditions and national regulations. In

25、 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.

31、n This European Standard constitutes the specific part related to building-integrated cogeneration 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 in buildings. This Eur

32、opean Standard specifies the structure for calculation of the system energy losses and the system performance of building-integrated cogeneration systems. The calculation method is used for the following applications: judging compliance with regulations expressed in terms of energy targets; optimisa

33、tion 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 with and without the energy conservation measure.

34、 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. Licensed copy:PONTYPRIDD COLLEGE, 05/01/2008, Uncontrolled Copy, BSI ? EN 15316-4-4:2007 (E) 6 1 Scope This European Standard defin

35、es a method for calculation of the energy requirements, electricity production, thermal output and recoverable losses of building-integrated cogeneration units forming part of a heat generation system (space heating and domestic hot water) in a building. Such units are commonly known as micro- or sm

36、all scale cogeneration, or micro- or small scale CHP. The calculation is based on the performance characteristics of the units, defined in product standards, and on other characteristics required to evaluate the performance of the units as included in the technical building system. The test of build

37、ing-integrated cogeneration units for heating systems may be worked out in a national annex. As soon as European test methods are available these should be used. NOTE Primary energy savings and CO2 savings, which can be achieved by cogeneration units compared to separate production of heat and consu

38、mption of electricity, are calculated according to prEN 15603. Indications about the savings calculations are given in informative Annex C. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited a

39、pplies. For undated references, the latest edition of the referenced document (including any amendments) applies. prEN 156031), Energy performance of buildings Overall energy use, CO2 emissions and definition of energy ratings 3 Terms and definitions For the purposes of this document, the following

40、terms and definitions apply. 3.1 annual load profile method calculation method for an installation where the cogeneration unit is sized to run on different load ranges throughout the year (e.g. the cogeneration unit operates as a boiler substitute and supplies the entire heat demand of the building)

41、 3.2 annual electrical efficiency total annual electrical output of the cogeneration unit divided by the total annual fuel input 3.3 annual heat efficiency total annual heat output of the cogeneration unit divided by the total annual fuel input 3.4 auxiliary energy electrical energy used by technica

42、l building systems for heating, cooling, ventilation and/or domestic hot water to support energy transformation to satisfy energy needs 1) To be published. Licensed copy:PONTYPRIDD COLLEGE, 05/01/2008, Uncontrolled Copy, BSI ? EN 15316-4-4:2007 (E) 7 NOTE 1 This includes energy for fans, pumps, elec

43、tronics etc. Electrical energy input to the ventilation system for air transport and heat recovery is not considered as auxiliary energy, but as energy use for ventilation. NOTE 2 In EN ISO 9488 the energy used for pumps and valves is called “parasitic energy“. 3.5 building-integrated cogeneration c

44、ogeneration unit installed to supply space heating, domestic hot water and possibly cooling within a building NOTE It could operate as the only heating/cooling appliance of the building or in combination with other heat generators, such as boilers or electrical chillers. Unlike district heating syst

45、ems, where heat and electricity are generated at central plants and transmitted through networks to a number of remote buildings, a building-integrated cogeneration unit produces heat for use within the building. The electricity produced by the integrated cogeneration unit may be used within the bui

46、lding or may be exported. 3.6 cogeneration unit unit designed to provide thermal energy and electricity to a building using a cogeneration process NOTE 1 The unit may include supplementary burners and thermal storage. NOTE 2 The cogeneration units are also called CHP (Combined Heat and Power) plants

47、 or units. 3.7 cogeneration simultaneous generation in one process of thermal energy and electrical and/or mechanical energy 3.8 design heat load desired heat flow necessary to achieve the specified design conditions 3.9 dumped heat wasted heat, which exceeds the current heat demand of the building

48、and cannot be stored or used 3.10 electricity from cogeneration electricity generated in a process linked to the production of useful heat 3.11 full load operation state of the technical system (e.g. cogeneration unit) where the actual load requirement is equal to the nominal (maximal) output capaci

49、ty of the device 3.12 fractional contribution method calculation method for an installation where the CHP unit is sized to run at full load most of the time, thus the heat output of the CHP unit supplies the base load of the installation (fractional contribution of the heat demand) 3.13 gross calorific value quantity of heat released by a unit quantity of fuel, when it is burned completely with
