A new classroom, laboratory, and studio facility designed by Thom Mayne of Morphosis Architecture with associate architect Gruzen Samton completed construction in Summer 2009, replacing the aging Hewitt Academic Building at 41 Cooper Square. In contrast to the Foundation Building, 41 Cooper Square is of modern, environmentally "green" design, housing nine above-ground floors and two basements. The structure features unconventional architectural features, including a full-height Grand Atrium, prevalent interior windows, a four-story linear central staircase, and upper-level skyways, which reflect the design intention of inspiring, socially interactive space for students and faculty. In addition, the building's design allows for up to 75% natural lighting, further reducing energy costs. Other "green" features in the design include servo-controlled external wall panels, which can be swiveled open or closed individually in order to regulate interior light and temperature, as well as motorized drapes on all exterior windows. In 2010, 41 Cooper Square became the first academic and laboratory structure in New York City to meet Platinum-level LEED standards for energy efficiency. The building was funded in part by alumni donations, materialized in nameplates and other textual recognition throughout the building.
