How Buildings Learn: What Happens After They're Built

by Stewart Brand

O’Neill’s A Hierarchical Concept of Ecosystems. O’Neill and his co-authors noted that ecosystems could be better understood by observing the rates of change of different components. Hummingbirds and flowers are quick, redwood trees slow, and whole redwood forests even slower. Most interaction is within the same pace level—hummingbirds and flowers pay attention to each other, oblivious to redwoods, who are oblivious to them. Meanwhile the forest is attentive to climate change but not to the hasty fate of individual trees. The insight is this: “The dynamics of the system will be dominated by the slow components, with the rapid components simply following along.”2 Slow constrains quick; slow controls quick. The same goes with buildings: the lethargic slow parts are in charge, not the dazzling rapid ones. Site dominates the Structure, which dominates the Skin, which dominates the Services, which dominate the Space plan, which dominates the Stuff.

Incredible stuff.
