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
