This project is the first air traffic control tower to earn LEED® Silver certification. Keeping with Chicago’s notable architectural heritage, the selected NATCT design is AECOM’s asymmetrical, cantilevered tower. A great addition to the city’s skyline, this tower prominently features C/S Louvers. C/S worked closely with the installer on the custom louver attachment. This unique attachment allows for lateral and rotational adjustment of the louvers giving them the appearance of seamlessly floating away from the structure.
