ENERGY STAR Labeled Building Profile
One South Dearborn
1 South Dearborn
Chicago, IL 60603
Developed, owned, and managed by Hines, One South Dearborn is a 40-story, 829,000-square-foot office tower in downtown Chicago. Designed by the architecture firm of DeStefano Keating Partners Ltd., One South Dearborn was completed in 2005. Its metal and glass exterior is distinguished by a twinned structural lantern at the building crown, rising some 60 feet above the top of the main structure. The building gains further distinction with features such as a 16,000-square-foot outdoor plaza with shade trees and a three-story lobby clad in glass and marble. Tenant amenities include an on-site fitness center, a bike room for tenant use, a conference facility, and 8,000 square feet of retail space.
One South Dearborn earned the ENERGY STAR for superior energy performance as a result of a comprehensive focus on energy efficiency that began with the property's initial design. For instance, the building's windows are an inch thick and have insulated dual panes and a low-E coating, all of which help to reduce the need for artificial lighting during daylight hours and help to control HVAC demand. Also on the HVAC side, 100 percent outside-air-economizer capabilities help to reduce demand for cooling when weather permits, while ducted supply risers help to improve overall efficiency by reducing air leaks within the system. And variable frequency drives (VFDs) on cooling tower fan motors help to keep condenser water temperatures at properly calibrated levels, reducing unnecessary consumption. In addition, all washrooms utilize efficient water-consuming fixtures. Finally, lighting is another focus, with occupancy sensors in common areas helping to reduce lighting demand when the building is unoccupied.
Hines has been recognized with a multiple ENERGY STAR Sustained Excellence and Partner of the Year awards. For a summary of the firm's participation in the ENERGY STAR program and other sustainability information, visit www.hines.com/sustainability.
