Sports stadiums and arenas showcase sustainability features

The newly opened $1.6 billion Mercedes-Benz Stadium in Atlanta earned LEED Platinum certification and is one of the latest sports venues to showcase sustainability.

Earning 88 out of a potential 110 points, the facility is the first sports arena to achieve the Platinum rating. Stadiums and arenas have become showcases for green design, with owners finding that they are cheaper to operate and generate positive publicity for their environmental responsibility.

The Golden 1 Center in Sacramento, home of the Sacramento Kings N.B.A. franchise, became the first LEED Platinum arena when it opened in 2016. Dozens of sports arenas and stadiums around the globe have installed solar panels, LED lighting and scoreboards, energy efficient air-conditioning and dehumidifiers, and composters.

Many use a translucent coating on windows to reduce solar heat gain. Mercedes-Benz Stadium, home to Atlanta Falcons of the N.F.L. and a Major League Soccer team, holds up to 680,000 gallons of rainwater collected from the roof.
