The $507 million Golden 1 Center is a multi-purpose indoor arena in downtown Sacramento, Calif., and is mostly known as the home of the NBA's Sacramento Kings.
With much anticipation, the Golden 1 Center officially opened during a ribbon-cutting ceremony Sept. 30, 2016, attended by NBA team owners, various political figures, current and former Kings players, as well as former Commissioner David Stern. The 17,500-seat arena will host concerts, conventions and other sporting and entertainment events. It features more luxury suites and a potential capacity of 19,000 seats. The building features five, one-of-a-kind bifold strap latch doors to be installed at the arena entrance.
Working architect AECOM Architecture’s client wanted something uniquely Sacramento. The city was replacing a failing mall and needed to renew a failing district for rejuvenation of the area. It involved working with the wonderful temperature, being able to have an indoor-outdoor expression.
The arena needed to meet the stringent California Title 24 Energy standards. “We are the first LEED Platinum arena in the whole world,” said Design Principal architect Rob Rothblatt of AECOM Architecture. “Part of being uniquely Sacramento is to be kind to the flora and fauna and celebrate farm-to-table and the delta. We are absolutely state-of-the-art in bird protection; it’s partly because of the doors. We don’t have any reflective glass. We have fritted glass and small panels that allow birds to see ahead of them. The doors are glazed with gray glass, so birds will never bang into them by mistake. We’ve had no crashes at all.”
These doors are also windows, with another set of conventional pedestrian doors at the base to handle foot traffic entering and exiting the arena.
Schweiss Doors engineered and built five one-of-a-kind bifold strap latch doors to be installed at the arena entrance. Three doors measure 29-ft. wide × 41-ft., 5-in. high, while the other two doors are 4-in. wider. Each door is lifted by three 5-horsepower motors with liftstraps 6-in. wide, double the normal width. The doors, constructed of glass, each weigh approximately 28,000 pounds.
Three motors, housed in the ceiling, require 480V, three-phase, 50-amp electrical power to raise the doors quickly, quietly and safely. The doors are glazed with a low-E safety-laminated glass. Three doors face down at an 11-degree angle to make them partly self-shading and to prevent unwanted reflections. The doors also can be controlled by an iPhone app.
