Bloom is a sun-tracking instrument made out of a smart thermobimetal, which curls when heated to create various shapes based on weather conditions.
A project by DOSU Studio Architecture, “Bloom” is a sun-tracking instrument that indexes time and temperature. It is made from a smart thermobimetal that responds to the sun, curling when it is heated to shade and ventilate areas of the shell. The environmentally responsive surface is made up of around 14,000 lasercut pieces and is designed for peak performance on the spring equinox.
The panels combine a double-ruled surface of bimetal tiles with an interlocking, folded aluminum frame system. Like the undulation of the surface, the frame, by nature of its folds, is designed to appear on the inner or outer surface at the same cadence of the peaks and valleys. The final monocoque form, lightweight and flexible, is dependent on the overall geometry and combination of materials to provide comprehensive stability.
The twisted panel shapes aid in the performance of the surface, as portions of a panel’s surface directly face the sun, while other areas are in the shade and require no reaction or curling. This results in a dramatic variation in tile shapes and function within each panel. DOSU Studio Architecture are further developing this project, combining responsive thermobimetal with glass to create a passive shading system.
