NOTE 2 If in future, models become available that combine global environmental impacts with health impacts
29、 to the building users due to direct exposure, these might be considered in the context of the CEN/TC 350 framework in future. Although the EN 15804 standard follows the LCA approach, it also states that additional information on release of dangerous substances to indoor air, soil and water during t
30、he use stage shall be provided (EN 15804:2012+A1:2013, 7.4). EN 15804:2012+A1:2013, 7.4.1 stipulates the requirements related to releases to indoor air, and EN 15804:2012+A1:2013, 7.4.2 stipulates the requirements related to releases to soil and water. Such releases are included in EN 15804 as these
31、 have a potential direct impact/risk for the inhabitants/users of the building. PD CEN/TR 17005:2016CEN/TR 17005:2016 (E) 6 Both EN 15804 and EN 15978 contain seven life cycle environmental impact categories. Since their publication, however, a perceived need has arisen to include in these standards
32、 a broader set of environmental impacts categories due to the following: Additional environmental impact categories are currently part of European recommendations and of national legislation of several Member States. Additional environmental indicators are used in current practice (see EN 15643-2:20
33、11, B.2 3). New research and developments in life cycle impact assessment (LCIA) methods and the characterization of environmental impacts. This Technical Report (TR) has been developed to provide guidance to the working groups of CEN/TC 350 on the extension of the impact categories in EN 15804 and
34、EN 15978. The TR provides a framework for the evaluation of environmental impact categories and evaluates the impact categories human toxicity and ecotoxicity, particulate matter, land use, biodiversity, water scarcity; and ionizing radiation by implementing the framework developed. During the prepa
35、ration of the TR a range of experts, such as developers of impact assessment models, LCA software developers and experts from the EC-JRC were consulted. NOTE 3 Although this report is primarily referenced to buildings, the indicators and methods reviewed might have equal application in other constru
36、ction works.

37、 Assessment LCI Life Cycle Inventory LCIA Life Cycle Impact Assessment PCR Product Category Rules PEF Product Environmental Footprint RA Risk Assessment TR Technical Report TSP Total Suspended Particles The standards EN 15804 1 and EN 15978 2 provide a basis for the environmental assessment of build
38、ings using a life cycle assessment approach. The EN 15804 standard 1 provides core product category rules (PCR) for Type III environmental declarations of any construction product and services. An Environmental Product Declaration (EPD) is a verified document that reports environmental data of produ
39、cts based on life cycle assessment (LCA) and other relevant information and in accordance with the international standard ISO 14025 (Type III Environmental Declarations). The EN 15978 standard 2 specifies the calculation method to assess the environmental performance of a building, based on LCA (i.e
40、. using EPD for construction products and services) and other quantified environmental information (i.e. (1) indicators describing resource use based on input flows of the life cycle inventory (LCI) and (2) indicators describing waste categories and output flows derived from scenarios and LCI), and
41、gives the means for the reporting and communication of the outcome of the assessment. Life cycle Assessment (LCA) is defined as the “compilation and evaluation of the inputs, outputs and the potential environmental impacts of a product system throughout its life cycle”. (ISO 14040). In LCA, the mode
42、lling is typically made at the global level, resulting in global characterization factors. Inherent to the modelling, the (current) environmental impact assessment models within LCA do not cover local impacts/risks due to direct exposure of some persons to a certain emission/hazardous substance. As
43、it is acknowledged that the variation in population density influences the exposure rate and hence also the potential health damage, regional characterization factors (based on regional differences in population density) for some health related impact categories are being developed. The same is true
44、 for ecosystems related impact categories. As is illustrated in Figure 1, LCA (in current practice) covers a great part of the total environmental perspective but is clearly restricted to regional and global impacts to the external environment (i.e. it does not include effects due to indoor exposure
45、 of the users of a building). Effects for which there is a low plausibility that they will occur (e.g. risks from nuclear waste) and local effects from the products PD CEN/TR 17005:2016CEN/TR 17005:2016 (E) 8 on the manufacturers or users are disregarded. Recently, research has started to also addre
46、ss health effects due to indoor emissions on building users with similar approaches as used in LCA 13. PD CEN/TR 17005:2016CEN/TR 17005:2016 (E) 9 1 Scope This Technical Report (TR) has been developed by CEN/TC 350/WG 1 and WG 3 to provide a clear and structured view on the relevance, robustness and
47、 applicability of a predefined set of additional impact categories and related indicators for the assessment of the environmental performance of construction works, construction products and building materials. The TR describes the evaluation criteria that are used to determine, for these impact cat
48、egories, the suitability of indicators and calculation method(s) for inclusion in the standards EN 15978 and EN 15804 (or other CEN/TC 350 standards as appropriate) in terms of their: a) relevance to: 1) the environment, 2) construction works, 3) construction products, and 4) EU policy; b) scientifi
49、c robustness and certainty; and c) applicability of the impact assessment method(s). The additional impact categories examined in the TR are: human toxicity and ecotoxicity; particulate matter; land use; biodiversity; water scarcity; and ionizing radiation. Because EN 15978 and EN 15804 are founded on a life cycle approach, the impact categories, indicators and methods reviewed are predominantly based on their potential suitability for application in LCA. In relation to some of the areas of concern, however, where LCA meth
