Advanced power and technology solutions support this 18,100 seat venue's dual commitment to world-class entertainment and carbon neutrality.

Transforming a Seattle landmark into the world's first zero-carbon arena required balancing historical preservation with cutting-edge technology. While maintaining the iconic 7-million-pound roof, we equipped the 932,000-square-foot facility for 18,100 fans with advanced power and sustainability solutions. The arena's power infrastructure includes ten 26,000-volt substations and a 5,000-volt emergency generator, enabling reliable operations while adhering to zero-carbon goals. High-density wireless coverage, supported by a distributed antenna system, ensures modern fan connectivity, while professional broadcast and audio-visual systems enhance the entertainment experience. Coordinating multiple trades under the preserved roof, we integrated systems for daily operations and world-class events, achieving groundbreaking sustainability in arena design.
