Problem statement
Proportion between materialisation and operation of a construction must be in balance for a sustainable life cycle
Low energy buildings have already reduced the operational energy demands
Minimise environmental impact of materialisation
Rethink the role of product’s expected life span
Starting point: curtain walls (widely used in office and commercial buildings)
Design phase Decision making Sustainability & Environmental Impact

Research question
- How long should a curtain wall live to have minimum environmental impact?
- Does stick or unitised curtain wall provide the most sustainable materialisation and service life?
