Rising over 800 feet, 300 North LaSalle is a 60-story office building in downtown Chicago. Not only one of Chicago’s tallest buildings, the project also is one of the city's most green. Its use of the adjacent Chicago River pioneered a new role for local landscape in urban development. Clark met the challenges of location and a tight schedule to erect this new addition to the Chicago skyline.

The 1.3 million square-foot 300 North LaSalle is located on the west side of LaSalle Street on the north bank of the Chicago River. It provides 52 levels of office space, seven levels of mixed-use space, three floors of underground parking, and two floors of mechanical and elevator levels. Sustainable features are incorporated throughout.

Clark used team work and creative solutions to meet the client's tight schedule. From the beginning of the project, the team identified the challenges of the timeline and carefully planned the execution of work over a year. This effort resulted in a close relationship between the team and the tenant's contractors and the ability of various contractors on site to work around each other. Clark also used the challenges of the very small site to their benefit; they turned the river into an access point, using barges to move materials and equipment to and from the site.

Sustainability

One of the most innovative, water- and energy-saving features utilizes the adjacent Chicago River. Through a series of gates and pipes that lead to the river water vault, the building's cooling system utilizes river water in lieu of domestic water as the condenser water for the HVAC system. This eliminated the need for cooling towers on the roof of the building and and the need to rely on domestic water. Additionally, rain water collected from the building roof is diverted into this system instead of going to the city’s already overburdened storm and sanitary system; rainwater also feeds the buildings irrigation system. This HVAC system saves the owner considerable operational and equipment costs as well as 10 million gallons of water evaporation annually. This use of the Chicago River is pioneering a new role for local landscape in urban development. 

Additional green features of 300 N. LaSalle include a green roof and use of the curtain wall and floor plans to maximize the daylight while minimizing solar heat gain. During construction, Clark surpassed the expectations of the City of Chicago and the U.S. Green Building Council by documenting almost 13,000 tons of waste diverted from landfills, resulting in 97 percent of all waste generated being diverted.
