Full Description

29 North Wacker, is a 10-story, 1962 vintage office building located in the heart of Chicago's downtown business district. The retrofit provided better comfort, controllability, reduction of noise and improvements in the aesthetics and space of each office. Specific improvements included upgrading the heating plant via a steamtowater conversion design, redesigning the perimeter induction system to incorporate chilled beams and installing a building automation system with Web-based direct digital controls (DDC).
