One of the greenest buildings in Chicago, 300 N. LaSalle is pre-certified LEED-CS Gold. The construction team diverted 97% of all construction debris from landfills.
One of the building’s most innovative, features uses the adjacent Chicago River. A series of gates and pipes that lead to the river water vault let the cooling system use river water, instead of domestic water, as condenser water for the HVAC system. This eliminates the need for cooling towers on the building’s roof and for drawing on domestic water. In addition, rain water from the building’s roof is diverted into this system instead of going to the city’s already overburdened combined storm and sanitary system. Rainwater also feeds the building’s irrigation system. This HVAC system saves considerable operating and equipment cost.
