A Gateway to Indianapolis
and a Sustainable Future

Indianapolis International Airport Colonel H. Weir Cook Terminal
Indianapolis, Indiana, USA

“The new air terminal creates an iconic destination for travelers to this Midwestern capital city while proving that it’s possible to decrease the airline industry’s environmental footprint.”

Architect magazine

The Colonel H. Weir Cook Terminal acts as a world-class gateway to Indianapolis while providing exceptional customer service and flexibility for future changes.

The building and its form represent Indianapolis’ vision for becoming a global crossroads. At the heart of the terminal, a 200-foot-wide room creates a great “Civic Plaza” where art, retail, social and civic functions converge and passengers can connect with the Indiana landscape. Capped with a hyperbolic glass and steel skylight, this room has become a threshold to the “crossroads of America.”

The desires to provide clarity for passengers and to achieve energy efficiency also give shape to the building. 

The hyperbolic roof reinforces the path of travel, defining both the great arched front as well as a passenger’s movement between landside and airside. In addition, the terminal roof is designed to shade the building’s curtain walls while providing scenic views of the Indiana landscape. The roof form, skylight and high-performance curtain wall systems were designed to work together to assure that primary building lighting is not in use during daylight hours throughout the departure level. These strategies are joined with a unique mechanical system of radiant floors and stratified ventilation that assure that only the building’s inhabited zone, below 10 feet, is tempered to human comfort.

“With views of the downtown skyline, the Indianapolis International Airport Colonel H. Weir Cook Terminal has been celebrated for its sense of place, and for treating its passengers as guests, much the way the hotel industry does,” reported City Lab. “It has its own civic plaza, a light-filled central space with 35-foot ceilings that functions as the nexus of activity—every passenger, whether arriving or departing, passes through—where half of all the airport’s shops and restaurants reside. Customers routinely comment on the terminal’s calm feel, and on its efficiency and easy navigation.”

This is the world’s first complete airport campus to earn LEED certification and one of the largest LEED-certified projects in the U.S

In 2016, for the third straight year, travelers selected Indianapolis International as the top U.S. domestic airport in the Condé Nast Traveler Readers’ Choice Awards.
