The atrium also plays a central role as the exhaust point of the center's passive-downdraft ventilation system. Cooling towers located along either side of the building serve as the system's air supply. And rooftop vacuum-tube thermal solar array also provides heat for the HVAC system.

The building's steel structure is a buckling restrained brace-frame system that absorbs seismic energy by allowing a building to flex, reducing the possibility of damage at key structural connections during earthquakes.
