The Variable Stiffness Lattice (VSL) building skin is a research project developed in Princeton University’s Form Finding Lab. The VSL skin system relies on novel design simulation and fabrication processes that explore elastic deformation mechanisms found in nature. Depending on the ambient exterior temperature, VSL skin openings change size to filter sun rays in summer days or maximize natural light in winter days using bimetallic lattices. The VSL system reflects a novel type of adaptive building facade that can reduce cooling and heating loads while minimizing maintenance costs as no actuation devices are required.
