Some background info via WAN: "The building’s form represents physical speed, beginning at signature prow - the symbolic and functional entrance into the interpretive traditional courtyard - and spirals up around the circumference of the dynamic circular form... Green roofs insulate the building and are part of a larger design strategy to address storm water management as well as to create an outdoor amenity for employees."
