BS EN 15978:2011 EN 15978:2011 (E)5 Introduction The purpose of this European Standard is to provide calculation rules for the assessment of the environmental performance of new and
30、 existing buildings. This European Standard is part of a suite of European Standards, Technical Specifications and Technical Reports for the assessment of the environmental performance of buildings that together support quantification of the contribution of the assessed building to sustainable const
31、ruction and sustainable development. The environmental performance of a building is only one aspect of its sustainability. The social and economic performance of the building are also aspects of sustainability that should be assessed as part of a sustainability assessment. These are described in the
32、 framework standards (EN 15643-1, -2, and EN 15643-3, -4). NOTE The environmental assessment at building level requires information from products and services (EN 15804). The evaluation of technical and functional performance is beyond the scope of this European Standard. Technical and functional ch
33、aracteristics are taken into account here by reference to the functional equivalent, which also forms a basis for comparison of the results of assessments. This European Standard is intended to support the decision-making process and documentation of the assessment of the environmental performance o
34、f a building. Although the assessment results are based on realistic scenarios, they may not fully reflect the actual and future performance of the building. Figure 1 illustrates how the assessment of the environmental performance takes place within the concept of the sustainability assessment of bu
35、ildings. Figure 1 Concept of sustainability assessment of buildings BS EN 15978:2011 EN 15978:2011 (E)6 In this European Standard, the assessment method for the quantitative evaluation of the environmental performance of the building is based on a life cycle approach. The general requirements for su
36、stainability assessment of buildings are described in EN 15643-1 (the general framework standard). Other requirements for the assessment of environmental performance are given in EN 15643-2. Other standards developed by CEN/TC 350 in this area, and how they are related to this European Standard, are
37、 shown in Figure 2. Figure 2 Work program of CEN/TC 350 NOTE The grey boxes represent the work programme as presented in EN 15643-1. BS EN 15978:2011 EN 15978:2011 (E)7 1 Scope This European Standard specifies the calculation method, based on Life Cycle Assessment (LCA) and other quantified environm
38、ental information, to assess the environmental performance of a building, and gives the means for the reporting and communication of the outcome of the assessment. The standard is applicable to new and existing buildings and refurbishment projects. The standard gives: the description of the object o
39、f assessment; the system boundary that applies at the building level; the procedure to be used for the inventory analysis; the list of indicators and procedures for the calculations of these indicators; the requirements for presentation of the results in reporting and communication; and the requirem
40、ents for the data necessary for the calculation. The approach to the assessment covers all stages of the building life cycle and is based on data obtained from Environmental Product Declarations (EPD), their “information modules“ (EN 15804) and other information necessary and relevant for carrying o
41、ut the assessment. The assessment includes all building related construction products, processes and services, used over the life cycle of the building. The interpretation and value judgments of the results of the assessment are not within the scope of this European Standard. 2 Normative references
