The first LEED certified residential tower in the Midwest, the 62-story, 1 million-square-foot 340 on the Park is a unique, modern aesthetic mix of glass and metal. Located in a prominent area of downtown Chicago, near Lake Michigan and facing Grant and Millennium Parks, the architects wanted the tower to fit into the rhythm of the area. The tower’s curtainwall consists of 32,000 square feet of organically coated aluminum panels from IEC Group Ltd. and 288,000 square feet of low-E tinted glass from Viracon. The panels are made of 0.1-inch-thick aluminum plate and are sprayed with a Duranar paint finish. In addition to the energy efficiency and recycled content of the aluminum panels and glass, the project features other recycled content materials, including 100 percent of concrete reinforcing steel and 90 percent of other miscellaneous metals. Additionally, 27 percent of the building products were locally manufactured and 2,800 tons of construction waste was recycled rather than sent to a landfill.
