Clearstory’s signage and wayfinding program is a response to Morphosis’s primary objectives of setting a bench­mark for sustainable building design, the opening of the typical office environment and creating an urban landmark. The utilization of energy-efficient skip-stop elevators promotes exercise and health as well as social interaction beyond the short elevator cab conversation. Clearstory’s program mirrored this conceptual thesis by employing a mass transit sign system aesthetic. The interior signage is reminiscent of a subway system map and sign program, utilizing both the graphic iconography and nomenclature.
