19、his 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of an identical text or by endorsement, at the latest by November 2007, and conflicting national standards shall be withdrawn at the latest by November 2007. The connections and relations to the different d
20、raft standards developed in the EPBD project are presented in the umbrella document of the CEN BT 173. This standard 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
21、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 the calculation of the energy performance of buildings. An overview of the whole set of standards is given in CEN/TR 15615, Explanation of the gener
22、al relationship between various CEN standards and the Energy Performance of Buildings Directive (EPBD) (“Umbrella document“). Attention is drawn to the need for observance of all relevant EU Directives transposed into national legal requirements. Existing national regulations with or without referen
23、ce to national standards, may restrict for the time being the implementation of the European Standards mentioned in this report. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria,
24、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, Sweden, Switzerland and United Kingdom.

25、 15239:2007 (E) 4 Introduction Energy Performance of Buildings Directive (EPBD) identifies clearly ventilation, in article 2 “Definitions” and 3 “Adoption of a methodology” (for the calculation of the energy performance), as a component of the energy consumption of buildings, such as heating, coolin
26、g or lighting. EPBD also mentions in article 4, “Setting of energy performance requirements” that “requirements shall take account of general indoor climate conditions, in order to avoid negative effects such as inadequate ventilation”. Considering the impact of ventilation on the energy consumption
27、 of the buildings, CEN has decided to also develop a methodology concerning the inspection of ventilation systems, as it is made for air conditioning and heating systems, following the requirements of the articles 3, 8 and 9 of EPBD. The inspection described here, is therefore intended to include al
28、l types of ventilation systems mechanical, natural and hybrid (including mechanical and natural ventilation). Starting from the general points that may lead to excessive energy consumption, a list of the corresponding checks according to the nature of the ventilation system is given. Other specific
29、points depending more from the typology of the ventilation system are then detailed. Indications on the frequency of inspection and on the improvements that may appear necessary depending on the results of the diagnostic are also given. The possibility to introduce classes is given in this standard
30、in order to leave Member States freedom to choose between different objectives and extent of inspection, within a harmonised framework. All inspection activities undertaken should be subject to compliance with all health and safety requirements for the persons involved. This standard also complement
31、s EN 15240 concerning the inspection of air conditioning systems for the inspection of the ventilation part that is to be performed in relation to 4.2 dealing with mechanical exhaust and/or supply ventilation systems. BS EN 15239:2007EN 15239:2007 (E) 5 1 Scope This standard develops the methodology
32、 required for the inspection of mechanical and natural ventilation systems in relation to its energy consumption. This standard applies to both residential and non residential buildings. The inspection may include the following issues, in order to determine the energy performance of the building and
33、 its associated mechanical / electrical plant: The system conformity related to the original and subsequent design modifications, actual requirements and the present building state. Correct operation of the mechanical, electrical or pneumatic components. Provision of an adequate and pure supply of v
34、entilation air. The functioning of all the controls involved. Fan power absorbed and specific fan power. Building air tightness. It is not the intention of the standard to provide a full ventilation system audit. Its purpose is to assess its functioning and its impact on energy consumption. It inclu
35、des recommendations on possible system improvements. NOTE The inspection, performed by an independent person to assess the system performance relating to energy consumption, is different from the maintenance that is performed to the owners requirements to maintain the optimum system performance. 2 N
