The Nashville City Center (NCC) is a 27-story office tower and is one of the more than 40 buildings that DES cools in downtown Nashville. The building, located at the corner of Sixth Avenue and Union Street, was designed by Hugh Stubbins, the architect for the Citicorp Center in New York City, and local architect Gresham, Smith and Partners.
NCC has relied on DES for cooling since the new energy-generation facility opened in 2003. Before that, NCC had been a customer of the old Nashville Thermal Transfer Corporation since 1988, when the building opened.
