The Citicorp Tower, also known as 601 Lexington Avenue, is a skyscraper located in New York City. It was completed in 1977 and was designed by Hugh Stubbins and Associates, with the structural engineering provided by Leslie E. Robertson Associates. At the time of its construction, the Citicorp Tower was the seventh tallest building in the world and the tallest in New York City, with a height of 915 feet (279 meters). It remained the tallest building in New York City until it was surpassed by the World Trade Center in 1970.
One of the most distinctive features of the Citicorp Tower is its 45-degree angled top, which was designed to provide additional space for mechanical equipment and to reduce the wind loads on the building. The building also has a unique structural system, which consists of a steel frame with diagonal braces that provide lateral stability. This system allows the building to have a more open and flexible floor plan, as the diagonal braces do not obstruct the interior space.
The Citicorp Tower was designed to be energy efficient and environmentally friendly, with features such as energy-efficient windows, low-flow plumbing fixtures, and a cooling system that uses rainwater to cool the building. It also has a green roof, which helps to reduce stormwater runoff and heat island effect, and a solar panel array, which generates electricity for the building.
The Citicorp Tower is home to a variety of businesses and organizations, including Citigroup, law firms, and media companies. It also has a shopping center and a public plaza, which are open to the public. The building has received numerous awards for its design and sustainability features, including the American Institute of Architects' National Honor Award for Architecture.
In conclusion, the Citicorp Tower is a notable example of modernist architecture and sustainable design. Its distinctive angled top and innovative structural system set it apart from other skyscrapers, and its energy-efficient and environmentally friendly features make it a model for future buildings.
