With Super Bowl LIV concluding this past weekend, Forefront would like to showcase arguably one of the most iconic and innovative sports entertainment venues in the world. The Mercedes-Benz Stadium in Atlanta, Georgia can be considered the future of the fan experience for sporting events, environmental design, and contemporary architecture.
The $1.5 billion Mercedes-Benz Stadium is the most sustainable sports facility on earth. It is LEED Platinum and the only stadium of its kind with a kinetic, retractable roof. Designed by HOK in collaboration with BuroHappold Engineering, the building broke ground in 2014 and officially opened in August 2017 during the Atlanta Falcons’ pre-season. The sculptural structure replaced the 25-year-old Georgia Dome which was demolished the previous month. Designed to emulate the Pantheon in Rome, it features a semi-transparent retractable roof that’s nicknamed “the oculus” that lets sunlight into the interior. Bill Johnson, design principal of HOK’s Kansas City office, said this “literal out-of-the-box” thinking was what won the over Falcons’ owner Arthur Blank who bankrolled the project.
The stadium’s kinetic roof consists of eight, 200-foot-long triangular “petals” made of lightweight ETFE (ethylene tetrafluoroethylene). These petals are fixed to 16 individual tracks that can move at different speeds. The Benz now holds the record for the largest application of a single ETFE membrane in the world at 143,000 square feet.
First Professional Sports Stadium to Achieve LEED Platinum in the U.S.
Several aspects define the Benz as ultra-green. It’s powered by 4,000 photovoltaics, including an array of solar panels designed as carports. Alone, these generate 617 kilowatt-hours of energy each year for the stadium and the surrounding neighborhoods. According to Johnson, up to 10 NFL games can be powered with this amount of energy.
Additionally, underneath the stadium is a 600,000-square-foot cistern that can hold up to 2 million gallons of rainwater. Johnson said the intervention has helped decrease flooding in this area of Atlanta, while simultaneously providing irrigation for local trees.
