Gang and her team refined the terrace extensions to maximize solar shading, and other sustainable features include a water-efficient irrigation system and energy-efficient lighting. The green roof on top of the tower base is one of the largest in Chicago. The tower is certified LEED-NC. Despite its effort to be sustainable, its monolithic concrete slab design without an insulation break transfers heat very efficiently from the inside to outside (winter) and from the outside to inside (summer) due to thermal bridging.
