26、e 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of an identical text or by endorsement, at the latest by March 2008, and conflicting national standards shall be withdrawn at the latest by March 2008. This document h
27、as 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 European har
28、monisation 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 heating systems;
29、 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 systems suc
30、h 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 Standards a.o
31、. 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 specifying shape, ma
32、terial, 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 some cases
33、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. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries
34、are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sw
35、eden, Switzerland and United Kingdom. BS EN 15378:2007EN 15378:2007 (E) 6 Introduction This European Standard specifies procedures and optional measurement methods to be used for the inspection and assessment of energy performance of boilers and heating systems, in order to provide advice to users o
36、n the replacement of boilers, other modifications to the heating system and on alternative solutions as required by article 8 of Council Directive 2002/91/EC. This European Standard includes, either in the normative text or in the informative annexes: inspection procedures; measurement procedures; c
37、alculation equations; sample reports; advice criteria. Procedures and methodologies defined in this European Standard are not intended to provide a full energy audit of the heating system. They are intended to: support identification of areas of possible improvements; define criteria to produce reli
38、able advice on possible improvements of the energy performance of boilers and heating systems through replacement of components or other measures. Any replacement of appliances or modification of the heating system following advice should be designed according to appropriate methodologies. This may
39、require additional input and investigation for detailed design and final check of economical effectiveness. Clauses 5 and 6 separately describe basic inspection procedures related to: regular inspection of boilers; one-off inspection of the entire heating system. This European Standard introduces in
40、spection classes by which different levels of inspection accuracy and detailed inspection requirements can be determined, because: the same inspection procedure and level of details cannot reasonably be required for any kind and/or any size of boilers/heating systems; there are currently significant
41、 differences among member states with respect to: heating systems typologies; legal and/or standard requirements; maintenance and inspection practices. Alternative and/or optional partial inspection procedures and measurement methods for boilers and for other sub-systems of the heating system are de
42、scribed in the relevant annexes. BS EN 15378:2007EN 15378:2007 (E) 7 Inclusion of/omission of/alternatives to individual inspection items, as well as border lines between classes. are specified through tables given in national annexes. If no specific national annex is available, default tables and i
43、nspection classes are given in Annex A. Tables in the national annexes may refer either to methodologies given in the annexes to this European Standard or to suitable existing national standards. This European Standard has been drafted to support inspection required by Council Directive 02/91/CE, th
44、at is “Regular inspection of boilers fired by non-renewable gaseous, liquid or solid fuel” and “One-off inspection of heating systems with boilers that are more than 15 years old”. This does not exclude the possibility to use this European Standard for other types of generation devices (e.g. warm ai
45、r heaters, heat pumps, thermal solar, CHP) and for domestic hot water systems, if appropriate additional classes are defined in the national annexes. BS EN 15378:2007EN 15378:2007 (E) 8 1 Scope This European Standard specifies inspection procedures and optional measurement methods for the assessment
46、 of energy performance of existing boilers and heating systems. Boiler types covered by this European Standard are: boilers for heating, domestic hot water or both; gas, liquid or solid fuel fired boilers. Parts of heating systems covered by this European Standard are: boilers, including generation
47、control; other generation devices; domestic hot water production facilities; heating distribution network, including associated components and controls; heat emitters, including components and controls; space heating control system; storage and associated components; domestic hot water control syste
48、m.
