A testament to environmental sustainability, 7 World Trade Center (WTC) is the first LEED Gold certified office tower in New York City and the first building to achieve LEED certification under the USGBC’s Core and Shell Criteria. Re-opened in May 2006, the 52-story, 1.7 -million-square-feet office tower was the last tower to fall on 9/11 and the first to be re-built. ABP was hired as the Commissioning Authority to work alongside the design team to provide air-handling units with VAV air distribution on every floor and a dedicated chiller plant for the data center.

$700 Million New Construction – Fifty-two story, 1.7 million sf commercial Class-A office building. Floors are 39,000-42,000 sf each. Adjacent 15,000 sf park.

Standing at 741-feet-tall, 7 WTC is a striking infrastructure. The specially commissioned glass façade is illuminated by natural light during the day, and reflecting programmed LED projection sequences at night. From interior spaces with awe-inspiring views, high ceilings and 45-foot column-free spans, to backup power systems, above-standard electrical capacity and next-generation HVAC systems, the tower offers an ultra-efficient, green experience for tenants. ABP worked alongside the design team to provide air- handling units with VAV air distribution on every floor and a dedicated chiller plant for the data center. Constructed with a reinforced concrete core and a steel superstructure, the safety systems incorporated into the building exceed New York City building code and Port Authority of New York and New Jersey requirements.

Located at 250 Greenwich Street, 7 WTC features a 15,000- square-foot triangular park that is irrigated by the rainwater that is collected on the rooftop. Trees and shrubs, as well as marble benches line an open plaza with a 30 ft-wide fountain, helping to strengthen the environmental values and features found within the tower. The 45- foot-high glass and marble lobby is an impressive sight for visitors to enjoy. A symbol of hope and resiliency for our country, 7 WTC sets the benchmark for construction with an environmental conscience.
