15、ermal performance of buildings and building components” the secretariat of which is held by SIS. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This

16、 document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This document is part of the set of standards and accompanying technical reports on the energy performance of buildings and has been prepared under a mandate given to CEN by t

17、he European Commission and the European Free Trade Association (Mandate M/480, see reference EF3 below). Directive 2010/31/EU recasting the Directive 2002/91/EC on energy performance of buildings (EPBD, EF4) promotes the improvement of the energy performance of buildings within the European Union, t

18、aking into account all types of energy uses (heating, lighting, cooling, air conditioning, ventilation) and outdoor climatic and local conditions, as well as indoor climate requirements and cost effectiveness (Article 1). The directive requires Member States to adopt measures and tools to achieve th

19、e prudent and rational use of energy resources. In order to achieve those goals, the EPBD requires increasing energy efficiency and the enhanced use of renewable energies in both new and existing buildings. One tool for this is the application by Member States of minimum requirements on the energy p

20、erformance of new buildings and for existing buildings that are subject to major renovation, as well as for minimum performance requirements for the building envelope if energy-relevant parts are replaced or retrofitted. Other tools are energy certification of buildings, inspection of boilers and ai

21、r-conditioning systems. The use of European standards increases the accessibility, transparency and objectivity of the energy performance assessment in the Member States facilitating the comparison of best practices and supporting the internal market for construction products. The use of EPB-standar

22、ds for calculating energy performance, as well as for energy performance certification and the inspection of heating systems and boilers, ventilation and air-conditioning systems will reduce costs compared to developing different standards at national level. The first mandate to CEN to develop a set

23、 of CEN EPBD standards (M/343, EF2), to support the first edition of the EPBD EF1 resulted in the successful publication of all EPBD related CEN standards in 2007-2008. The mandate M/480 was issued to review the mandate 343, as the recast of the EPBD raised the need to revisit the standards and refo

24、rmulate and add standards so that they become on the one hand unambiguous and compatible, and on the other hand provide a clear and explicit overview of the choices, boundary conditions and input data that need to be defined at national or regional level. Such national or regional choices remain nec
