The Federal Aviation Administration has chosen the New York-based Practice for Architecture and Urbanism (PAU) studio to design the country’s newest air traffic control towers. I.M. Pei‘s iconic mid-century towers will be replaced by PAU’s adaptable and highly sustainable prototype, which offers a unique architectural solution that combines form and function for the twenty-first century. The new towers are vital to U.S. Transportation Secretary Pete Buttigieg’s goal to reach net-zero greenhouse gas emissions from the U.S. aviation sector by 2050. They have been updated to reflect aviation technology, safety development, and changing environmental and climatic conditions.
