BG Group Place

BG Group Place (formerly MainPlace) is a 630 ft (192 m) tall skyscraper under construction in Downtown Houston, Texas. It is expected to be completed in 2010 and will have 46 floors. It has been pre-certified Platinum LEED. When it is completed, BG Group Place, will become the 15th tallest building in Houston and will feature a skygarden on the 39th floor. It is the tallest building built in Houston in 23 years, after the Heritage Plaza was completed in 1987. According to the building's website, MainPlace will be ready for occupancy by February 2011. The naming was done when BG Group Plc became an anchor tenant and leased 164,000sq ft of space.

Environmental features

Features included in the building is a 39th-floor skygarden, and a fully gardened top floor of the parking garage, that soak up rainwater. Water that condenses in the building's air-conditioning system is used to irrigate the plants.

Glass fins act as sunshades reduce the building's need for air-conditioning. The 10-foot ceilings (a foot higher than the modern standard) allow in more sunlight, cutting the need for electric lights.
