17、 is held by SIS. 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of an identical text or by endorsement, at the latest by December 2007, and conflicting national standards shall be withdrawn at the latest by December 2007. This document has been prepare
18、d 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 harmonisation of t
19、he methodology for the calculation of the energy performance of buildings. An overview of the whole set of standards is given in CEN/TR 15615. Attention is drawn to the need for observance of EU Directives transposed into national legal requirements. Existing national regulations (with or without re
20、ference to national standards) may restrict for the time being the implementation of this European Standard. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, C

23、g designers, owners, operators and users to improve the energy performance of buildings. This European Standard provides methods to express the energy performance of buildings in a way that serves these purposes. It is based on standards that provide methods to calculate or measure energy performanc
24、e. This European Standard is intended to be used: by developers of a procedure for building energy certification; by building authorities setting minimum requirements on the energy performance; by building designers, building owners, building operators and building users to assess the performance of
25、 a planned or existing building and ways to improve it, and to express this performance.

26、indicators to express the energy performance of whole buildings, including heating, ventilation, air conditioning, domestic hot water and lighting systems. This includes different possible indicators; b) ways to express energy requirements for the design of new buildings or renovation of existing bu
27、ildings; c) procedures to define reference values; d) ways to design a procedure for building energy certification. The standard can be applied to a group of buildings, if they are on the same lot, if they are serviced by the same technical building systems and if no more than one of them has a cond
28、itioned area of more than 1 000 m2. This European Standard provides different options at different levels. When this European Standard is used to set up national or regional methods for expressing energy performance and/or for energy certification of buildings, the choices between the options is not
29、 made by the individual user, but by authorized national or regional bodies. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the refer
30、enced document (including any amendments) applies.

32、 of a building NOTE The meaning of the terms “certificate” and “certification“ in this European Standard differ from that in EN ISO/IEC 17000. 1) prEN 15603 is a merge of prEN 15203 and prEN 15315.

Lighting is always included except (by decision of national bodies) for residential buildings. 3.7 standard energy rating calculated energy rating using actual data for a building and a standard use data set NOTE 1 The thermal envelope area represents the intrinsic annual e
