Architects and engineers aren't always able to predict how their buildings are going to affect the surroundings once the project has been completed. It's interesting to note that the Surya Sunlight-Responsive Sculpture was designed to counteract a flaw of a single skyscraper.
Dallas's Museum Tower features highly reflective curtainwall cladding that shines brightly upon the Renzo Piano Nasher Sculpture Center. This is detrimental to the objects kept inside the gallery spaces. The solution by REX NY was to construct an enormous brise-soleil that would block the intense direct beams throughout the day. At nearly 400 feet in height, an odd egg-shaped wheel was erected with cable spokes meeting in the middle. Opaque squares begin to bloom and block light across Surya, opening and closing according to the changing concentration and angle of the rays.
