Commissioning authority: The Hearst Corporation
Principal designer: Foster + Partners
Principal contractor: Turner Construction
The Hearst Corporation, one of the largest publishing firms in the US, wanted a new corporate headquarters to bring together its 2,000 employees in New York City. The result is not just a striking addition to the New York skyline, but a demonstration of sustainable design which takes the whole concept of the green office in the city a step forward.
The tower has a distinctive triangulated framed structure. This diagrid frame is highly efficient, using around 20 per cent less steel than a conventional perimeter frame – a saving of around 2,000 tonnes of steel.
British architects were responsible not only for the shell and core of the new building, but also for its fit-out. Emphasis was placed on achieving a highly energy-efficient building and, as a result, the Hearst Tower is the first occupied building to achieve the coveted Gold rating in the US Green Building Council’s Leadership in Energy and Environmental Design programme.
The tower uses low-emission glass, and light and motion sensors to control lighting. Rainwater is harvested and fed into the air conditioning, the plant-watering systems and the building’s water feature.
Communication with local contractors with much off-site prefabrication has led to a highly successful addition to the Manhattan skyline and a delighted client – an enviable legacy of British influence in the international arena.
