Suncor Energy Centre 3.79

The Suncor Energy Centre, formerly the Petro-Canada Centre is a 1,945,000 square foot project composed of two granite and reflective glass-clad office towers of 32 floors and 53 floors, situated in the office core of downtown Calgary, Alberta. At 215 m, the west tower is the 13th tallest building in Canada and the fourth tallest skyscraper outside of Toronto, having been surpassed on July 8, 2010 by the neighbouring Bow. The office towers encompass 1,702,000 square feet of rentable office space with the complex also containing 243,000 square feet of retail and underground parking area. A glass-enclosed walkway provides shelter, and easy access to the surrounding buildings.The building was often called Red Square in its early years, a derisive reference to its primary occupant Petro-Canada, which was a Crown Corporation at the time. Petro-Canada has since been privatized and in 2009 was acquired by the building's current namesake, Suncor Energy.Shortly after completion, two BASE jumpers parachuted successfully off the building's roof in the early morning of Aug 28, 1983.Major tenantsMajor tenants of the Suncor Energy Centre include Suncor Energy Inc., Precision Drilling Corporation, Taqa North, Crescent Point Energy, Enbridge, Direct Energy, PricewaterhouseCoopers and Weatherford Canada.
