A Benchmark for Sustainable Airports

Indianapolis International Airport, Col. 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

A new gateway to the city of Indianapolis, the Col. H. Weir Cook Terminal is a high-performance building that minimizes the airport’s environmental footprint.

Vast yet efficient, the terminal achieved LEED certification through a series of strategies to address airport-specific challenges in the areas of site, energy, water and occupant comfort. It is the world’s first LEED-certified airport campus and one of the largest LEED-certified buildings in the US.

The midfield location of the new building between its two primary runways saves time, money and jet fuel, reducing aircraft emissions. Discharges from fuel and de-icing are controlled using bioswales populated with plants that consume hydrocarbons.

The terminal’s tailored roof has apertures sized to create evenly distributed natural light, reflect heat, channel water and harness airflows that draw clean air through the space. The roof also channels rainwater for collection and use inside the terminal.

A natural convection heating and cooling system is projected to save 21 percent in energy usage by only supplying cool air to the space occupied by passengers.

Construction of the terminal recycled 7,000 tons of old taxiway and roadway material by using it as site fill. More than 90 percent of the materials came from within a 500-mile radius of the site.

In a J.D. Power and Associates survey, the Indianapolis Airport received the highest customer satisfaction score of any North American airport. Airports Council International named it the best airport in North America in 2010, 2012, 2013 and 2014. In 2013, Travel + Leisure rated it one of America’s best airports.
