Designed by Cook & Fox Architects, the 58-floor Bank of America Tower is famed for its striking crystal shape, piercing 255ft spire, and enviable green credentials. The stats are impressive: a clean-burning, on-site cogeneration plant providing around 65% of the tower's annual electricity requirements; CO₂-detecting air filters that channel filtered air where needed; and even destination-dispatch elevators designed to avoid empty car trips.

The role-model skyscraper was awarded 'Best Tall Building in America' at the Council on Tall Buildings & Urban Habitat awards in 2010.
