15、iography 31 EN 15217:2007 (E) 3 Foreword This document (EN 15217:2007) has been prepared by Technical Committee CEN/TC 89 “Thermal performance of buildings and building components”, the secretariat of which is held by SIS. This European Standard shall be given the status of a national standard, eith
16、er 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of an identical text or by endorsement, at the latest by December 2007, and conflicting national standards shall be withdrawn at the latest by December 2007.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 prepared under a mandate given to CEN by the European Commission and the European Free Trade Associat
17、ion (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 the methodology for the calculation of the energy performance of buildings. An overview of the
18、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 reference to national standards) may restrict for the time being the implementation of this Euro
19、pean 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, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, I

EN 15217:2007 (E) 4 Introduction Expression of the energy performance of buildings is needed: to enable the establishment of regulat
21、ions regarding energy performance of buildings; to encourage building 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 stan
22、dards that provide methods to calculate or measure energy performance. 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
23、, building operators and building users to assess the performance of a planned or existing building and ways to improve it, and to express this performance. EN 15217:2007 (E) 5 1 Scope This European Standard specifies: a) overall indicators to express the energy performance of whole buildings, inclu
24、ding 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 buildings; c) procedures to define reference values; d) ways to design a
25、 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 conditioned area of more than 1 000 m2. This European Standard provides di
26、fferent 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 made by the individual user, but by authorized national or regional b

29、 following apply. 3.1 energy certification procedures enabling to produce an energy certificate 3.2 energy certificate document recognised by a member state or a legal person designated by it, which includes the energy performance of a building NOTE The meaning of the terms “certificate” and “certif
30、ication“ in this European Standard differ from that in EN ISO/IEC 17000. 1) prEN 15603 is a merge of prEN 15203 and prEN 15315.

31、lated value against which an energy indicator is compared 3.5 energy performance requirement minimum level of energy performance that is to be achieved to obtain a right or an advantage: e.g. right to build, lower interest rate, quality label 3.6 calculated energy rating energy rating based on calcu
32、lations of the weighted net delivered energy used annually by a building for heating, cooling, ventilation, domestic hot water and lighting NOTE National bodies can decide whether other energy uses resulting from occupants activities such as cooking, production, laundering, computer equipment etc. a
33、re included or not. If included, standard input data needs to be provided for the various types of building and uses. 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 an
34、d a standard use data set NOTE 1 The thermal envelope area represents the intrinsic annual energy use of a building under standardised conditions. This is particularly relevant to certification of standard energy performance. NOTE 2 It can also be termed “asset energy rating“. 3.8 design energy rati
35、ng calculated energy rating using design data for a building and a standard use data set NOTE It represents the calculated intrinsic annual energy use of a designed building under standardised conditions. This is particularly relevant to obtain a building permit at the design stage. 3.9 tailored ene
36、rgy rating calculated energy rating using actual data for a building, and actual climate and occupancy data 3.10 standard use data set standard input data for internal and external climates, use and occupancy NOTE 1 This set can also include information on surroundings (such as shading or sheltering
37、 by adjacent buildings). NOTE 2 Such data sets are defined at national level. 3.11 measured energy rating energy rating based on measured amounts of delivered and exported energy NOTE 1 The measured rating is the weighted sum of all energy carriers used by a building, as measured by meters or other
38、means. It is a measure of the in-use performance of a building. This is particularly relevant to certification of actual energy performance. NOTE 2 Also known as “operational rating“.

47、 can be used. This leads to different areas for the same building. NOTE 2 Some services, such as lighting or ventilation, might be provided to areas not included in this definition (e.g. a car park). NOTE 3 The precise definition of the conditioned area is given by national authorities. NOTE 4 Condi
