Design for QUALITATIVE USE

124Dimensional Design: a definition

“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”

26CONCLUSIONS

1. Combining life cycle design measures

2. Design of a Meccano3. Detailing is a key element4. Design and assessment

are used in an iterative way

5. Integrative life cycle model
