Designed by IwamotoScott, Edgar Street Towers was commissioned by the Alliance for Downtown New York's Greenwich South design study for Lower Manhattan. The project adapts to the specifics of its Greenwich Street site, including the approach to the Brooklyn Battery Tunnel and the reestablishment of Edgar Street (a blocked former cross-town urban connection) at the towers' base, as well as an alignment with Fifth Avenue to the north experienced at the towers' top. The mixed use program includes a branch library, arts and retail spaces in the lower third, commercial office space in the middle third, housing in the upper third, and a sky lobby and skyscraper museum at the top. Sustainable strategies deployed includes a bio-filtration atrium, a fiber-optic daylighting system transmitting light downwards from the towers top, and parametric structural skin whose porosity is adapted for optimum environmental control. The project received an Honor Award in the 2010 San Francisco AIA Design Awards.
