13、national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Inte

14、rnational organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with th

15、e rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval b

16、y at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15686-6 was prepared by Technical Committee

17、ISO/TC 59, Building construction, Subcommittee SC 14, Design life. It is closely related to standards in the ISO 14000 series (environmental management). While it does not conflict with these, it complements them by describing how environmental management standards, especially ISO 14040, may be impl

18、emented in the context of ISO 15686. ISO 15686 consists of the following parts, under the general title Buildings and constructed assets Service life planning: Part 1: General principles Part 2: Service life prediction procedures Part 3: Performance audits and reviews Part 5: Whole life costing Part

19、 6: Procedures for considering environmental impacts Part 7: Performance evaluation for feedback of service life data from existing construction works Part 8: Reference service life Part 4 is under preparation. BSISO156866:2004 iv Introduction Buildings and other constructed assets will require care

20、 from the initial proposal through to design, construction, operation, maintenance and disposal if they are to meet the required levels of performance. ISO 15686-1 and ISO 15686-2 explain the principles of service life planning (SLP) for different types of constructed assets, components and assembli

21、es. This part of ISO 15686 defines how and when to include environmental aspects into the design of a constructed asset. It provides a procedure for assessing the relative environmental impacts of design options and it identifies the interface between environmental life cycle assessment (LCA) and SL

22、P. The approach allows for consistent comparisons to be made between two or more design options taking the relevant factors from SLP into account. The target audience for this part of ISO 15686 includes the client, design professionals and consultants, and the entire decision supply chain represente

23、d in the design team. It will also be relevant to stakeholders and specialists providing information on service life and on environmental impacts.

24、ronmental impacts 1 Scope This part of ISO 15686 describes how to assess, at the design stage, the potential environmental impacts of alternative designs of a constructed asset. It identifies the interface between environmental life cycle assessment and service life planning (SLP). NOTE In order to

25、illustrate the context of ISO 15686-6, other performance criteria are referred to, but they are not defined within its scope. 2 Normative references The following referenced documents are indispensable for the application of this document.

30、lting from an organizations environmental aspects ISO 14001:, definition 3.6 4 Description of the procedure for considering environmental impacts 4.1 General Environmental impacts associated with constructed assets can be significant and should often be addressed in project planning. Every product h

31、as some impact on the environment. These impacts can occur at any or all phases of the products life cycle and can be local, regional or global, or a combination of all three. NOTE Improvements in one aspect of concern can lead to a reduction of performance in another field. This part of ISO 15686 d

32、oes not give any recommendation concerning the balance between environmental and other aspects. 4.2 Integrating environmental assessment into SLP The assessment of environmental impacts of a design option should in most practical cases be performed in parallel with technical and economic assessments

33、. In general, these assessments have a common purpose: information about the product should be assessed in order to provide the decision maker, and other stakeholders, with comprehensive and reliable information about the products performance. As constructed assets have long service lives, some of t

34、he underlying information should be drawn from the product application context and from scenarios concerning technical and economic performance, as well as user- related aspects. The assessment deals with predicted performance, and may not give the same result as a post-life retrospective performanc

35、e evaluation. The purpose of SLP is to create a realistic picture of the predicted performance and to make such performance scenarios more accurate. The early incorporation of internal and external interests, representing a broad sphere of bodies from stakeholders to the planning team, will assist i

36、n successfully addressing environmental aspects. This early involvement in the setting and communication of environmental goals as well as participation in the assessment procedure decreases the potential of a conflict of interests. Results of environmental assessment are intended to allow the desig

37、n team to include environmental aspects into their decision making. Comparing and assessing the relative environmental impacts of design options require detailed information about these options and the context of their application. Usually, LCA-based environmental information about construction prod

38、ucts and their supply chain can be acquired for early life cycle phases of these products (see Figure 3). Direct comparisons of product or design alternatives should include information concerning use phase and end of life (see ISO/TR 14025 and ISO 21930). Consequently, for later life cycle phases (

39、scenarios from current position to end of life), the assessor will have to complete the information by adding estimates for the processes in the other significant life cycle phases. The service life should be predicted on the basis of product performance as well as the expected application context,

40、where relevant. When integrating environmental assessment into SLP, the predicted service life of a design option should reflect the current application. The better the scenarios for service life, including maintenance and exposure to deterioration processes, reflect the current situation and the mo

41、re they are based on information determined with reference to other parts of ISO 15686, the more accurate the assessment will be. BSISO156866:2004 34.3 Positioning in project planning and the life cycle The exercise of SLP and environmental assessment may occur prior to, or during, any phase in the

42、life cycle of a constructed asset. The clients brief as well as building regulations have significant influence on the formulation of the initial concept for the project. Goals identified in regulations and the clients brief, paired with goals in the management routines of the parties represented in

43、 the project team can be translated into performance requirements. In relation to these requirements, a technical, economic and environmental assessment should be carried out, as indicated in Figure 1. Depending on the degree to which a design option fulfils the performance requirements, the project

44、 team can make the decision whether or not to include a design option. Again, the level of detail of an assessment and the character of the underlying information depend on the current phase in project planning. Early in the planning process, as in the initial design stage, the information will be l

45、ess accurate and more general and directional. Later, in detailed design, many decisions concerning the constructed asset have already been made and the assessment can be made in more detail. Meanwhile, the earlier the design team considers environmental matters, the easier it will be to identify de

46、sign solutions that meet identified requirements. Decisions, as well as underlying information, should be well documented and ultimately be included in the project documentation. Figure 1 Technical, economic and environmental assessment in SLP and the location of project planning in the life cycle o

47、f the building/constructed asset 4.4 Design options and functional equivalency When there are options available to fulfil a requirement, the goal is to enable the decision maker to make a tentative decision and to implement the option that best meets the requirements. NOTE 1 Identification of design

48、 options is not considered in this part of ISO 15686. In order to make meaningful comparisons of options, their functional equivalency should be determined. When that equivalency has been established, the decision should be based on criteria such as initial cost, whole life cost and environmental im

49、pacts, or a combination of these. In this context, some criteria may be assigned greater importance than others. BSISO156866:20044 Fitness for purpose should be included in the technical assessment. To make a meaningful environmental comparison between two design options, they should be equivalent in their fitness for purpose and other technical criteria. Economic criteria may not necessarily be equivalent. NOTE 2
