1 life cycle management zurich. 29 august 2007 life cycle design in building design and construction andrea campioli. monica lavagna. politecnico di milano. dipartimento best

2 objective of presentation

3 from eco-materials... natural recycled renewable local and durable

4 ... and from eco-building... high tech low tech light tech

5 ... toward life cycle management of building process - use one - - use two - life time of the building life time of the building life time of the product

6 ... toward life cycle management of building process life time of the building life time of the product life time of the product

7 the role of service life scenarios in life cycle assessment of buildings

8 the objects of LCA in building sector - building products - buildings

9 closed systems - building production (plant) - building

10 open system - building site

11 building site as production phase product A product A +B +... wall building performance of product performance of wall performance of building product building eco-performance of product eco-performance of wall eco-performance of building

12 building site as assembling phase

13 the objects of LCA in building sector

14 the role of service life in LCA of buildings

15 the role of service life in LCA of buildings life time of the building life time of the product life time of the product

16 the role of service life in LCA of buildings - use one - - use two - life time of the building life time of the building life time of the product

17 life cycle management of buildings

18 life cycle management of buildings Life Cycle Management in building sector means to put the service life scenarios in the project phase. To choose materials and technical solutions is necessary: - to know life time expected (temporary building or permanent building) - to know the kind of use (optimisation of the use of the spaces by creating multifunctional spaces) - to know durability of space and building components (flexibility and adaptability) -to optimize the service life of the building (by maintenance and components substitution)

19 design for reducing (design for lightness) - reduce energy and raw materials necessary for producing components - reduce energy consumption during transport (using lightweight materials)

20 design for reducing (design for lightness) - optimize and intensify the use of spaces with multifunctional spaces

21 design for extending useful life of buildings - guarantee the possibility, during use phase, of adaptation and flexible use of the spaces - use materials with the same durability - encourage the upgrading and reuse of existing components

22 design for maintenance (in permanent building) - use of durable materials - use materials with long life expected and low maintenance - guarantee the possibility, during use phase, of maintenance and cleaning

23 design for reusing (in temporary building) - use of recycling materials - minimize the number of materials (avoid composite materials) - use mechanical than chemical connections (for disassembling)

24 life cycle assessment of buildings and of products

25 design for disassembling (in temporary building) expected life-time: 10 years

26 design for maintenance (in permanent building) expected life-time: 100 years replacement every 25 years (durability of building components)
