Come on Down: 125 Broad Street is Lower Manhattan’s First LEED Silver Tower

In a Downtown first, the large regional REIT Mack-Cali has earned a LEED-EB:OM Silver rating for its 40-story, Class A office tower in the heart of the Financial District.

125 Broad Street Lobby

Mack-Cali, the real estate investment trust, announced today that 125 Broad Street has earned a Silver rating from USGBC under the LEED for Existing Buildings: Operations & Maintenance rating system. The 40-story, Class A tower is the first commercial office building in the Downtown submarket (not including the World Trade Center) to earn a LEED Silver rating (or, as it would appear in USGBC’s database, any level of LEED certification).

Mack-Cali bought out SL Green’s condominium interest in 125 Broad Street back in 2007. Since then, it has upgraded the building’s lighting and plumbing fixtures, installed efficient air filters, implemented a building-wide recycling program, and earned a 2010 Energy Star award from EPA (with a score of 79). A new building management system also helps monitor electricity, steam, and chilled water consumption in real-time. The 1.3 million-square-foot building is managed by Cushman & Wakefield, which actually raised the building’s Energy Star score from 49, and reduced its carbon footprint by 6667 tons, in just 2 years. Funding for the retrofit came through NYSERDA incentive programs and carbon offset trading.

125 Broad Street Elevation“This important designation enhances the institutional quality of this Class A building,” said Mack-Cali CEO Mitchell Hersh in a press release. “Today, businesses and government agencies are more environmentally conscious and are looking specifically for office properties that are energy efficient and more sustainable, with a goal of reducing their overall carbon footprint.”

Located in the heart of the Financial District, 125 Broad Street was built in 1970 and designed by architects Kahn & Jacobs and Carson Lundin & Shaw. Its tenant roster includes Citigroup and the global law firm Sullivan & Cromwell. Mack-Cali owns or has interests in 278 properties, primarily office and office/flex buildings located in the Northeast, totaling approximately 32.4 million square feet. CodeGreen provided LEED consulting services for 125 Broad Street’s EB:OM application.
