Owned and managed by Hines, 303 East Wacker is a 28-story, 838,000-square-foot office tower in downtown Chicago's East Loop area. Built in 1979 and designed by Fujikawa Johnson & Associates, the property is a handsome International Style tower, distinguished by a curtain wall of bronze-finished aluminum and reflective glass, and a two-story colonnaded arcade at ground level. Other building features include connections, via enclosed pedestrian walkways, to two hotels, five office towers, and a commuter railway station.


Hines and J.P. Morgan Investment Management, Inc. acquired 303 East Wacker in 1998 and undertook an extensive renovation of the building's finishes and systems, with The Environments Group as renovation architect. In the wake of the renovation, 303 East Wacker received the Building Owners and Managers Association (BOMA) Office Building of the Year Award (Renovated Building category) in both 1999 and 2000.


303 East Wacker earned the ENERGY STAR for superior energy performance as a result of both retrofits made during the renovation process and changes in energy management practices. For example, a new computerized building automation system was installed, enhancing control over energy-consuming equipment and enabling close monitoring of energy consumption, startup times, etc. HVAC upgrades were performed as well, including the installation of new Variable Air Volume (VAV) boxes, which allow the distributed volume of cooled return air to vary according to cooling demand. Heating equipment controlled by Silicon Controlled Rectifiers (SCRs) was installed as well. The SCRs operate like automatic dimmer switches, allowing heating equipment to operate according to actual demand.


Hines has been recognized with 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
