Design for change: Part 1: diversified lifetimes

Extract

Buildings are constructed, expanded, refurbished, demolished, deconstructed and relocated in response to the essential needs of contemporary societies. Inevitably, these needs evolve with time. Modern design and construction have always operated in a constantly shifting context of requirements and resources. It is well known that unanticipated forces and emerging circumstances have compelled change in architecture through the ages and yet, most buildings are constructed to serve for countless decades (Kronenburg, 2000, Brand, 1994). During that time, buildings are exposed to an enormous range of fluctuating pressures. In this age of furious technological innovation, growing global ecological awareness and changing economic and societal priorities, the pace of change is increasingly frenetic. Out of this state of affairs arise both significant challenges and intriguing opportunities.
