Last month, Citi’s flagship branch – right here in Union Square – earned LEED Platinum certification. The 9,700-square-foot branch opened in December of 2010 and features six interactive sales walls, free online access and Wi-Fi for customers; 24/7 access to customer service experts; Energy Star-rated equipment; and energy-optimized lighting controls. The branch is located at the corner of 14th Street and Broadway. In fact, almost one-quarter of the Flagship location’s building materials were manufactured from recycled content. Pretty cool.
