24、-3:2007 (E) 4 Foreword This document (EN 15316-4-3:2007) has been prepared by Technical Committee CEN/TC 228 “Heating systems in buildings”, 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
25、by endorsement, at the latest by January 2008, and conflicting national standards shall be withdrawn at the latest by January 2008.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/343), and supports essential
26、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 standards is given in prCEN/TR 1561
27、5. 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 of the design heat loss an
28、d 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 the system as a whole and
29、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 the system requirements. The
30、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 functional requirements might be use
31、d 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 contradict with national regulations
32、, the latter should be followed. EN 15316 Heating systems in buildings Method for calculation of system energy requirements and system efficiencies consists of the following parts: Part 1: General Licensed Copy: London South Bank University, London South Bank University, Thu Dec 20 03:29:32 GMT+00:0

38、nts 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. The calculation is based on the performance characteristics of the products given in product sta
39、ndards 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 regulations expressed in terms of energy targets; optimisation of the energy performance of a planned he
40、at 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 i.e. the energy savings of a thermal solar sys
41、tem 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 documents for input data and detailed calculation procedures not provided by this European Standard.

43、iciencies. The framework for the calculation 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
44、 both. The following typical thermal solar 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 Ta
45、sk 26 Solar Combisystems of the IEA Solar Heating 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.
