|The building known by Bostonians as the John Hancock Tower, or colloquially, the "New" Hancock Tower, is officially named Hancock Place. It is a 60-story, 790-foot-tall (241 meter) skyscraper designed by I.M. Pei and Henry N. Cobb of the firm of Pei, Cobb and Freed. It was completed in 1976. In 1977 the AIA presented Cobb with a National Honor Award for the John Hancock Tower.|
As of 2005, it is the tallest building in New England, the 43rd tallest building in the United States, and the 112th tallest building in the world.
Its street address is 200 Clarendon Street. The company uses both "Hancock Place" and "200 Clarendon Street" as mailing addresses for offices in the building. The John Hancock companies were the main tenants of the tower, but the insurance company announced in 2004 that some offices will relocate to a new building at 601 Congress Street.
Like all large, heavily glazed buildings, the tower requires substantial air conditioning year round—even with its reflective walls. Its cooling system is similar to that used in the IDS Center in Minneapolis, Minnesota.
