Design Principles
"Functional integration: Design systems to perform multiple beneficial functions, such as vibration damping and energy generation."
This approach offers a novel pathway for sustainable building design by transforming a passive safety feature into an active energy generation system. It presents an opportunity to offset a building's energy consumption and enhance its environmental performance.
What This Means for Your Design
Imagine a big building swaying in the wind. We can put a special heavy pendulum inside that not only stops the building from swaying too much but also uses that swaying motion to create electricity, like a mini power generator.
