Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees
15、is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.

20、:2016(E)IntroductionISO 15686, with the general title Buildings and constructed assets Service life planning, of which this document is Part 7, is an important contribution to the development of a policy for design life. A major impetus for the preparation of the parts of ISO 15686 is the concern ov
21、er the inability to predict service life, costs of ownership and maintenance of buildings and constructed assets. Common methods and standards for performance assessment and proper feedback of data from practice are decisive in order to make experience data from the building stock more consistent an
22、d comparable.This part of ISO 15686 provides a framework to channel information, collected as part of building performance surveys and assessments, into structured data that can be used in various aspects of the service life planning process.By applying the generic protocol and terms from this part
23、of ISO 15686, to evaluate the service life performance during a buildings life cycle, practitioners can generate “inuse” service life data, as referenced in ISO 156862 and ISO 156868 .The inspection and reporting procedures described in this part of 15686, acknowledge that both the condition, of any
24、 given building, component or system, as well as performance requirements, can change during the lifecycle. Those changes typically result in corrective actions, maintenance or recommissioning, to rectify the performance gaps. While commissioning, recommissioning and maintenance planning are beyond
25、the consideration of this document, the interactions and significance of initial inspection data, maintenancedriven inspections, changed performance expectations, performance surveys, service life predictions and service life planning are discussed.Part 10 of ISO 15686 stipulates that functional per
26、formance is to be assessed at various stages during the whole life, most critically during the project delivery phase, and at commissioning. Functional performance assessments are to continue during the property management phase and when considering disposal, to compare actual serviceability profile
27、 of the facility to the generic or typical functional requirement profile of potential occupants or buyers. This part of ISO 15686 provides essential input to the functional performance review process of ISO 1568610 and as such is of importance to all members of the building team.Part 4 of ISO 15686
28、 lays out procedures for the application of Building Information Modelling (BIM), specifically to provide a consistent computerized structure for the retention and use of service life planning information and service life predictions. Coupled with the emergence and inherent capabilities of BIM, the
29、techniques described in this part of ISO 15686 will become more useful, lead to better service life estimations and generally improve service life planning.

30、: Performance evaluation for feedback of service life data from practice1 ScopeThis part of ISO 15686 provides a generic basis for performance evaluation for feedback of service life data from existing buildings and constructed assets, including a definition of the terms to be used and the descripti
31、on of how the (technical) performance can be described and documented to ensure consistencies.The purpose of this part of ISO 15686 is to describe the principles for service life performance surveys and evaluation with an emphasis on technical recommendations. It aims to describe a generic methodolo
32、gy, including the terms to be used, that provide guidance on the planning, documentation and inspection phases, as well as on analysis and interpretation of performance evaluations, both on the object (single building) and network (stock of buildings) level. While maintenance planning is outside the
33、 scope of this part of ISO 15686, this standard acknowledges that maintenancedriven inspections, and subsequent recommended actions, could have significant effects upon service life and performance.ISO 156867 is intended for all members of a building team, e.g. building owners and developers, profes
34、sional advisors, constructors, assessors, manufacturers of building products, insurers, managers of both publicly and privately owned constructed assets.2 Normative referencesThe following referenced documents, in whole or in part, are normatively referenced in this document and are indispensable fo
