The Staples Center, home of the Los Angeles Lakers, Clippers and Kings sports teams, is currently the world's largest indoor entertainment venue. Designed by NBBJ Architects, Staples features a sloping roof and tilted walls. Over 400 sq. ft. of louvers were custom manufactured to the exact dimensions to align properly with the tilted wall condition. 11' tall trapezoidal louvers can be found on all sides of the center. At the office and retail entrance, an elliptical tower houses a C/S Vert-A-Cade 300 roof screen to provide ventilation to the HVAC equipment. C/S louver blades were stretch-formed to provide proper blade alignment on all sides of the ellipse.
