200 GREENWICH STREET
FOSTER AND PARTNERS
ARCHITECTURAL FACT SHEET - SEPTEMBER 2006

SITE INFORMATION
200 Greenwich Street (Tower 2) is located on the site bounded by Greenwich Street to the west, Church Street to the east, Vesey Street to the north and Fulton Street to the south. It will be east of the proposed Performing Arts Center and north of the Transportation Hub.

PROGRAM
200 Greenwich Street, a 78-story tower, will be the second tallest skyscraper on the World Trade Center site and in New York City. The tower will rise to 1,254 ft and be topped by an antenna of 85 ft.

The tower will contain 143,000 sq ft of retail (of which 95,000 sq ft is at or above street level), 60 office floors, including a sky-lobby, that total 2.3 million sq ft and a 65-foot high office lobby. It will have a total of nine entrances: five entrances from street level, two below-grade entrances from the WTC Transit Hub and two from the retail area.

The first office floor begins at 583 ft above street level. A typical office area offers more than 36,000 sq ft of space. There will be four trading floors totalling 219,200 sq ft and 11.5 levels of mechanical floors.

DESIGN CONCEPT
Designed by Foster and Partners, 200 Greenwich Street's sparkling glazed crystalline form and diamond shaped summit create a bold addition to the New York skyline.

Arranged around a central cruciform core, the tower comprises four blocks containing light-filled, flexible, column free office floors that rise to the 59th floor, whereupon the glass façades are sheared off at an angle to address the Memorial Park. Giving the building its distinctive inclined summit as the second tower in the World Trade Center Master Plan, 200 Greenwich Street also acts as a symbolic marker of the location of the Memorial Park when viewed from any location. The upper floors contained within the summit provide the opportunity for spectacular multiple-height function rooms with sweeping views of the park, the river and the city.

A continuation of Foster and Partners' investigation into the nature of the tower, 200 Greenwich Street takes structural, functional, security, environmental and urban logic to a new dimension. The tower is influenced by the geometry of the site, with the cruciform core providing the structural backbone as well as the key organizing diagram. It accommodates the primary vertical circulation, with high-speed shuttle elevators rising to an intermediate sky lobby where the upper floors are served by two further banks of elevators. It also allows for cross-corridor circulation by providing excellent orientation at every level, and opening views out across the office spaces.

Extending the logic of the core, the volume of the tower is punctuated on all four sides by notches - elegantly breaking up the mass of the tower into four interconnected blocks. Towards the perimeter, the core culminates in dedicated flexible zones with the opportunity to create staircases between floors, and the possibility for double-height atria. These zones can be an integral part of the building's environmental strategy by drawing fresh air into the building during spring and autumn.

Connections with the city at street level have been reinforced with glass walls creating a visual relationship with the surrounding streets. The imposing double-height ground floor lobby is connected at the Greenwich Street entrance to the MTA providing direct access to the underground infrastructure system. The lobby rises in level along Vesey Street and includes a further connection with the transport system via escalators and a four-story shopping area connecting with Fulton Street and spilling out onto the Wedge of Light plaza.

BUILDING SYSTEMS
The tower will consist of a central concrete core—steel encased in reinforced concrete—and an external structural steel frame. Safety systems will exceed New York City building code and Port Authority requirements. Designed to the highest energy efficiency ratings, 200 Greenwich Street will seek to achieve the gold standard under the Leadership in Energy and Environmental Design (LEED) by the US Green Building Council.

PROJECT SCHEDULE
200 Greenwich Street is expected to be completed by 2012.
