4. Current design view Towards an integrative life cycle model

5. land-filling Life cycle thinking ? incineration Towards an integrative life cycle model

6. feedstock recycling material recycling Towards an integrative life cycle model

7. reuse of components Towards an integrative life cycle model

8. renovation – restoration of building reuse of building Towards an integrative life cycle model

9. Towards an integrative life cycle model

10. land-filling • combustion • feedstock recycling • material recycling • reuse of components • renovation/restoration of building • reuse of building Towards an integrative life cycle model

11. Design for QUALITATIVE USE • + • Design for DISMANTLING • (material reuse) • Design for DECONSTRUCTION • (component reuse) • Design for ADAPTABILITY & VERSATILITY • (building reuse) Design for REUSE Towards an integrative life cycle model

12. “it refers to an ATTITUDE of the designer, through which he uses his horizontal knowledge to provide an artefact with a sustainable character” “a 4D designer accepts that not only building materials and components degrade over time, but that also the context of the building will CHANGE” “he/she has to provide a DYNAMIC answer, wherein buildings, components and materials support the process of changing events, instead of creating END PRODUCTS” 4Dimensional Design: a definition

13. 4Dimensional design

15. 8M x 2 4M 2M M 4dimensional design

16. What are the environmental benefits of this 4Dimensional Design approach? • Environmental load? • Potential savings on embodied energy and natural resources CASE: temporary construction (PSO) Conservation of Resources By Designing a Meccano For Temporary Constructions Conservation of resources
