Anaheim Regional Transportation Intermodal Center (ARTIC) in California by HOK

The Anaheim Regional Transportation Intermodal Center (ARTIC) sets a precedent for civic-minded transit hubs in the US. HOK and Parsons Brinckerhoff designed ARTIC as an innovative new transit station that serves as a destination in itself. The project brings together transit, dining, retail and entertainment options in an iconic terminal building.

The transit hub links commuter and regional rail service and intercity bus systems including Amtrak, Metrolink, OCTA bus service and Anaheim Resort Transportation. ARTIC’s flexible design ensures that it can serve as a southern terminus for California’s future highspeed rail system.

Officials challenged the team to create an icon that would welcome a new age of public transportation. The station was also conceived as a catalyst for transforming Anaheim’s core into a pedestrian-friendly zone that promotes connectivity. Known as the “Platinum Triangle,” the area around the station includes Angel Stadium, the Honda Center, the Anaheim Convention Center and Disneyland. The master plan establishes a clear pedestrian pathway flanked by future mixed-use development with ARTIC as the primary destination. The extroverted building has a significant but welcoming presence and will help spur transit-oriented development.

Drawing inspiration from classic grand transit halls including Grand Central Terminal in New York, along with the structural elegance of local airship hangars, the team developed a 21st-century design concept. The design achieves its signature parabolic form by employing a diagrid structural system of diamond-shaped steel arches infilled with translucent ETFE (ethylene tetrafluoroethylene) pillows. At the north and south ends, freestanding curtain walls bring in daylight and offer expansive views. The longspan, grid shell structure creates a grand, light-filled atrium space that accommodates open circulation.

The team used building information modeling (BIM) to develop ARTIC’s complex form, geometry and functions. BIM helped the team navigate the building systems and study the building’s tolerances and environmental performance.

ARTIC is designed for LEED Platinum certification. The vault-shaped structure acts in concert with advanced mechanical systems to optimize energy efficiency. Inflated ETFE cushions cast a soft, translucent light throughout the great hall, while the additional frit pattern on the outer layer reduces solar heat gain. Convection currents naturally ventilate the building as heat rises from the lower south end up to the north side and out through operable louvers. The radiant heating and cooling floor system and optimized HVAC system will help reduce ARTIC’s energy consumption by 50 percent.

LED lights mounted on the diagrid structure illuminate the ETFE pillows in gradations of shifting colors, providing a striking presence on the night skyline. As darkness falls, ARTIC becomes lit from within and acts as a beacon from the freeways and local streets.
