Innovation in stainless steel gives Harvard’s most energy-efficient structure sustained brightness.

One of the most energy-efficient structures in the world, Harvard University’s Science and Engineering Complex (SEC), features a revolutionary stainless steel sunscreen that combines sustainability and architectural genius.

Made from lace-like Type 316L stainless steel, the SEC in Allston, Massachusetts, has the first hydroformed stainless steel shade screen in the world. With 12,800 interlocking panels, this creative tensile façade system moderates interior temperatures by letting in sunshine in the winter and blocking out solar heat gain in the summer, thereby reducing energy consumption all year long.

The panels, which are 0.75 x 0.75 meters in size and weigh less than 4.5 kg each, are carefully laser-cut for the best possible light diffusion and are formed using sophisticated hydroforming techniques. 1.5 mm stainless steel was chosen after extensive testing because it had the perfect ratio of strength to formability. The panels’ post-formation annealing and built-in stiffening folds provide structural robustness without sacrificing their delicate, fabric-like appearance.

The SEC, which was designed by Behnisch Architekten, incorporates extremely efficient heat exchangers, rainwater recovery, and natural ventilation. It is certified as a Living Building Challenge Petal and LEED Platinum. The future of green building is embodied by this stainless steel sunscreen, where functionality, aesthetics, and environmental responsibility all coexist harmoniously.
