23、art 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 impacts and aspects to assess the environmental, social and economic performance of buildings using
24、 quantitative and qualitative indicators, both of which are measured without value judgements. 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. This series of standard
25、s 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 sustainability asses
26、sment 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 life cycle stages included in the assessment. In carrying out assessments, scenarios and a
27、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 1. Assessments can
28、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 characteristics are considered
29、 within this framework by reference to the functional equivalent. The functional equivalent takes into account the technical and functional requirements and forms a basis for comparisons of the results of the assessment. Any particular demands for, or related to, the environmental, social and econom
30、ic performance defined in the clients brief, or in regulations, may be declared and communicated. Figure 1 shows how the functional equivalent and the technical and functional characteristics that differ from those required, either by the clients brief or through regulations, are to be declared and
31、communicated with the results of the assessment. NOTE The outer box with the dotted line represents the area to be standardised by CEN/TC 350. Figure 1 The concept of sustainability assessment of buildings BS EN 15643-2:2011EN 15643-2:2011 (E) 5 In concept, the integrated building performance incorp
32、orates 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. Although the assessment of technical and functional performance does not form part of this series of standards, their
33、 interrelationship with environmental, social and economic performance is 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 during the conceptual stages of a construc
34、tion 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 support decision making. A final assess
35、ment (as-built) should be carried out. The results of this final assessment can be used to inform all parties concerned. NOTE The darkened boxes represent the work programme of CEN/TC 350. Figure 2 The work programme of CEN/TC 350 This European Standard EN 15643-2 is Part 2 of the framework standard
36、s for sustainability assessment of buildings. The purpose of EN 15643-2 is to provide a framework with principles, requirements and guidelines to assess the environmental performance of buildings. It focuses on the principles and requirements for the assessment of the environmental performance of a
37、building as described at the “framework level“ in Figure 2. In the drafting of this European Standard, ISO 21930 and ISO 21931-1 have been taken into consideration. BS EN 15643-2:2011EN 15643-2:2011 (E) 6 The first revision of the general framework standard, EN 15643-1, will combine all four parts o
38、f the framework of this series of standards into one framework standard. This will ensure simultaneous revision of the interlinked parts of the frameworks within the series of standards. In the future, the assessment methodologies within this series of standards may be part of an overall assessment
39、of integrated building performance. The assessment methodologies may also be extended to an assessment of the neighbourhoods and wider built environment. BS EN 15643-2:2011EN 15643-2:2011 (E) 7 1 Scope This European Standard forms one part of a series of European Standards and provides the specific
40、principles and requirements for the assessment of environmental performance of buildings taking into account technical characteristics and functionality of a building. Assessment of environmental performance is one aspect of sustainability assessment of buildings under the general framework of EN 15
41、643-1. The framework applies to all types of buildings and it is relevant for the assessment of the environmental performance of new buildings over their entire life cycle, and of existing buildings over their remaining service life and end of life stage. In this series of standards, the environment
42、al dimension of sustainability is limited to the assessment of environmental impacts and aspects of a building on the local, regional and global environment. The assessment is on Life Cycle Assessment and additional quantifiable environmental information expressed with quantified indicators. It excl
43、udes the assessment of a buildings influence on the environmental impacts and aspects of the local infrastructure beyond the area of the building site, and environmental impacts and aspects resulting from transportation of the users of the building. It also excludes environmental risk assessment. Th
44、e standards developed under this framework do not set the rules for how different building assessment schemes may provide valuation methods. Nor do they prescribe levels, classes or benchmarks for measuring performance. NOTE Valuation methods, levels, classes or benchmarks may be prescribed in the r
45、equirements for environmental, social and 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 environmental aspects of organizations are not included within th
46、is framework. However, the consequences of decisions or actions that influence the environmental performance of the object of assessment are taken into account. 2 Normative references The following referenced documents are indispensable for the application of this document.
