Since opening in 1994, Kiel Center Arena (now known as Savvis Center) has become the central entertainment venue for the St. Louis area. The 664,000 sq.ft. sports and entertainment complex is capable of seating between 20,000 and 22,000 spectators for hockey and basketball events.

WTA designed the mechanical/electrical systems for the facility including the central chilled water plant, the ice rink systems, the central boiler plant, 1,500 kW emergency generator, and air and lighting distribution throughout the seating bowl. Project issues included

• New air handling units designed with advanced filtering which allow substantial reductions of outdoor air quantities below nominal code requirement limits while maintaining indoor air quality
• New switchgear and multiple substations that consist of new 15 kV switchgear, three automatic transfer feeders, and a medium voltage loop feeding four double-ended substations dispersed around the Kiel and one for the Opera House
• Bowl lighting system is considered state-of-the-art, the HID lighting system is dimmable to 1% output and is controlled from a central station with preset schemes for the various venues

The Kiel Center Arena bowl lighting was granted an International Illumination Regional Design Award
