Sustainable Design

SDI's staff consists of designers who can assist the team reach its environmental goals in areas such as
energy use, air quality, water and heat reclamation, trash removal, and recycling. Recently we completed
Apogee Stadium, the first newly constructed LEED Platinum stadium in the country; Sabre Corporate Campus
in Southlake, Texas, the first Silver-certified building in Texas and one of largest in the country; and Aviva
USA's new headquarters, the largest LEED-gold certified building in Iowa and one of only five its size or
larger in America to achieve that designation. We also worked recently on the US Census Bureau
Headquarters in Suitland, Maryland. The 1.5 million-square-foot facility is one of the nation's largest
green buildings and was designed for a Silver rating. It used recycled building materials, water-saving
fixtures, and glazed reflective windows.
