Attention is drawn to the possibility that some of the elements of this document

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Aust

This docu

25、ment 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 2002/91/EC on the energy performance of buildings (EPBD). It forms part of a series of standards aimed at Europe

26、an 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. BS EN 15603:2008EN 15603:2008 (E) 5 Introduction Energy assessments of buildings are carried out for various purposes, such as: a) Judgi

27、ng compliance with building regulations expressed in terms of a limitation on energy use or a related quantity; b) Transparency in commercial operations through the energy certification and/or display of a level of energy performance (energy performance certification); c) Monitoring of the energy ef

28、ficiency of the building and its technical building systems; d) Helping in planning retrofit measures, through prediction of energy savings which would result from various actions. This standard specifies a general framework for the assessment of overall energy use of a building, and the calculation

29、 of energy ratings in terms of primary energy, CO2emissions or parameters defined by national energy policy. Separate standards calculate the energy use of services within a building (heating, cooling, hot water, ventilation, lighting) and produce results that are used here in combination to show ov

30、erall energy use. This assessment is not limited to the building alone, but takes into account the wider environmental impact of the energy supply chain. An allowance is made for energy that may be generated within, or on the surface of the building and which is used to offset fuel and power drawn f

31、rom other sources. Energy generated on the building site and exported is credited, provided it is exported for use elsewhere. Energy certification of buildings requires a method that is applicable to both new and existing buildings, and which treats them in an equivalent way. Therefore, a methodolog

32、y to obtain equivalent results from different sets of data is presented in this standard. A methodology to assess missing data and to calculate a standard energy use for space heating and cooling, ventilation, domestic hot water and lighting is provided. This standard also provides a methodology to

33、assess the energy effectiveness of possible improvements. Two principal types of energy ratings for buildings are proposed in this standard: e) calculated energy rating; f) measured energy rating. Because of the differences in the way these two ratings are obtained, they cannot be directly compared.

34、 However, the difference between the two ratings for the same building can be used to assess the cumulative effects of actual construction, systems and operating conditions versus standard ones and the contribution of energy uses not included in the calculated energy rating. Local values for factors

35、 and coefficients needed to calculate primary energy and CO2emissions related to energy policy should be defined in a national annex. NOTE Energy is not produced, but only transformed. In this standard however energy is used in one form by systems that generate other forms of energy. At its final st

36、age in the building, energy is used to provide services such as heating, cooling, ventilation, hot water, lighting, etc.BS EN 15603:2008EN 15603:2008 (E) 6 1 Scope The purpose of the standard is to: a) collate results from other standards that calculate energy use for specific services within a buil

37、ding; b) account for energy generated in the building, some of which may be exported for use elsewhere; c) present a summary of the overall energy use of the building in tabular form; d) provide energy ratings based on primary energy, carbon dioxide emission or other parameters defined by national e

38、nergy policy; e) establish general principles for the calculation of primary energy factors and carbon emission coefficients. This standard defines the energy services to be taken into account for setting energy performance ratings for planned and existing buildings, and provides for this: f) method

39、 to compute the standard calculated energy rating, a standard energy use that does not depend on occupant behaviour, actual weather and other actual (environment or indoor) conditions; g) method to assess the measured energy rating, based on the delivered and exported energy; h) methodology to impro

40、ve confidence in the building calculation model by comparison with actual energy use; i) method to assess the energy effectiveness of possible improvements. This European standard is applicable to a part of a building (e.g. flat), a whole building, or several buildings. It is up to national bodies t

41、o define under which conditions, for which purposes and for which types of buildings the various ratings apply. This standard handles the energy performance of a building as a whole. The assessment of the energy performance of specific technical building systems is handled in the appropriate part of
