DIN EN 15978:2012-10 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 existing buildings. This European Standard is part of a suite of
31、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 construction and sustainable development. The environmental performance
32、 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 framework standards (EN 15643-1, -2, and EN 15643-3, -4). NOTE Th
33、e 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 characteristics are taken into account here by reference to the func
34、tional 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 of a building. Although the assessment results are based on realist
35、ic 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 buildings. Figure 1 Concept of sustainability assessment of building
36、s DIN EN 15978:2012-10 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 sustainability assessment of buildings are described in EN 1564
37、3-1 (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 shown in Figure 2. Figure 2 Work program of CEN/TC 350 NOTE
38、The grey boxes represent the work programme as presented in EN 15643-1. DIN EN 15978:2012-10 EN 15978:2011 (E) 7 1 Scope This European Standard specifies the calculation method, based on Life Cycle Assessment (LCA) and other quantified environmental information, to assess the environmental performan
39、ce 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 of assessment; the system boundary that applies at the bu
40、ilding 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 requirements for the data necessary for the calculation. The app
41、roach 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 out the assessment. The assessment includes all building
42、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 The following referenced documents are indispensable for
