Life-Cycle Performance - a key aspect in

• requirement setting
• performance-based building
• service life planning
• life cycle management systems
• construction products directive
• energy performance of buildings directive
• Commissions FP priorities
• sustainable building policies

4
International Standardization...

• is a consensus-building process
• is a participatory process
• relates to other standards (ISO) and directives
  or policies (CEN)
• harmonizes existing approaches
• is performance based rather than prescriptive
• gives companies a reliable business environment
• ISO SC14, SC17 and CEN TC350 standards aim to
  enable the exchange of service life and
  sustainability information related to
  internationally traded products and services

5
Pre- and Co-normative RD

• advance the subject field while international
  harmonization is ongoing
• embedded in standardization activities
• feed into standardization process
• apply - develop - re-supply

6
Recent and Current Projects

• CEN TG Durability
• CEN TC350
• ISO TC59 SC14
• ISO TC59 SC17
• IAI (IFC model)

• WoodAssess
• LIFECON
• LIFETIME
• PeBBu
• ENDOHOUSING
• STAND-INN
• SMART-ECO

7
Common basis in standards

• describe - quantify - assess
• interpretation of impacts in relation to
  identified performance requirements
• life cycle perspective
• service life as temporal reference frame
• modular structure to allow methodology as well as
  information integration (IFC)

8
key-concern definitions

• life cycle consecutive and interlinked stages of
  the object of consideration
• period of analysis length of time over which an
  object is analyzed
• service life period of time after installation
  during which a building or its parts meet or
  exceed the performance requirements
• performance expression relating to the magnitude
  of a particular aspect of the object of
  consideration relative to specified requirements,
  objectives, targets or a combination thereof.

besides durability life-performance RD needs

• requirement setting
• requirement model - development over time
• balancing of requirements and objectives from
  different origins

• translation of requirements from building level
  to object level
• link between requirements and functional
  equivalence / functional unit
