BS EN 15643-4:2012EN 15643-4:2012 (E) 4 Introduction This Eur
21、opean Standard forms part of a series of European Standards, written by CEN/TC 350, that provide a system for the sustainability assessment of buildings using a life cycle approach. The sustainability assessment quantifies aspects and impacts to assess the environmental, social and economic performa
22、nce of buildings using quantitative and qualitative indicators, both of which are measured without value judgments. The purpose of this series of standards is to enable comparability of the results of assessments. This series of European Standards does not set benchmarks or levels of performance. Th
23、is series of standards will allow the sustainability assessment, i.e. the assessment of environmental, social and economic performance of a building, to be made concurrently and on an equal footing, on the basis of the same technical characteristics and functionality of the object of assessment. The
24、 sustainability assessment of buildings uses different types of information. The results of a sustainability assessment of a building provide values for the different types of indicators, the related building scenarios, and on the lifecycle stages included in the assessment. In carrying out assessme
25、nts scenarios and a functional equivalent are determined at the building level Assessment at the building level means that the descriptive model of the building with the major technical and functional requirements has been defined in the clients brief or in the regulations, as illustrated in Figure
26、1 below. Assessments can be undertaken for the whole building, for parts of the building which can be used separately, or for elements of the building. Although the evaluation of technical and functional performance is beyond the scope of this series of standards, the technical and functional charac
27、teristics are considered within this framework by reference to the functional equivalent. The functional equivalent takes into account the technical and functional requirements and forms the basis for comparisons of the results of the assessment. Any particular demands for, or related to, the enviro
28、nmental, social and economic performance defined in the clients brief, or in regulations, may be declared and communicated. Figure 1 below shows how the functional equivalent, and the technical and functional characteristics that differ from those required, either by the clients brief or through reg
29、ulations, are to be declared and communicated with the results of the assessment. BS EN 15643-4:2012EN 15643-4:2012 (E) 5 NOTE The outer box with the dotted line represents the area to be standardised by CEN/TC 350. Figure 1 Concept of sustainability assessment of buildings In concept, the integrate
30、d building performance incorporates environmental, social and economic performance as well the technical and functional performance, and these are intrinsically related to each other, as illustrated in Figure 2 below. Although the assessment of technical and functional performance does not form part
31、 of this series of standards, their interrelationship with environmental, social and economic performance is a prerequisite for an assessment of sustainability performance of buildings and, therefore, is taken into account. It is advisable to carry out an assessment at the earliest opportunity durin
32、g the conceptual stages of a construction or refurbishment project such as in the sketch plan stage in order to provide a broad estimate of the environmental performance, social performance and economic performance. As the project evolves, the assessment may be periodically reviewed and updated to s
33、upport decision-making. A final assessment (as built) should be carried out. The results of this final assessment can be used to inform all parties concerned.

34、f CEN/TC 350 This framework is Part 4 of the framework standards for sustainability assessment of buildings. The purpose of this EN 15643-4 is to provide a framework with principles, requirements and guidelines for the assessment of the economic performance of a building, as described at the “framew
35、ork level“ in above Figure 2. The first revision of the general framework standard, EN 15643-1, is intended to combine all four parts of the standard into one framework standard. This will ensure simultaneous revision of the interlinked parts of the standard. In the future, the assessment methodolog
36、ies within this framework standard may be part of an overall assessment of integrated building performance. The assessment methodologies may also be extended to an assessment of the neighbourhoods and wider built environment. BS EN 15643-4:2012EN 15643-4:2012 (E) 7 1 Scope This European Standard for
37、ms one part of a series of European Standards for the assessment of buildings and provides specific principles and requirements for the assessment of economic performance of buildings taking into account technical characteristics and functionality of a building. Assessment of economical performance
38、is one aspect of sustainability assessment of buildings under the general framework of EN 15643-1. The framework applies to all types of buildings and it is relevant for the assessment of the economic performance of new buildings over their life cycle, and of existing buildings over their remaining
39、service life and end of life stage. The economic performance assessment of a building addresses the life cycle costs and other economic aspects, all expressed through quantitative indicators. It excludes the economic risk assessment of a building and return on investment calculations It includes eco
40、nomic aspects of a building relating to the built environment within the area of the building site, it does not include economic aspects beyond the area of the building site, e.g. such as economic impacts of construction of local infrastructure or economic impacts resulting from transportation of th
41、e users of the building or economic impacts of a construction project on local community. The standards developed under this framework do not set the rules for how the different assessment methodologies may provide valuation methods nor do they prescribe levels, classes or benchmarks for measuring p
42、erformance. NOTE Valuation methods, levels, classes or benchmarks may be prescribed in the requirements for economic performance in the clients brief, building regulations, national standards, national codes of practice, building assessment and certification schemes, etc. The rules for assessment of
43、 economic aspects of organizations, such as management systems, are not included within this framework. However, the consequences of decisions or actions that influence the economic performance of the object of assessment are taken into account. 2 Normative references The following referenced docume
