With plans to host the 2014 World Cup and then the 2016 Olympics, Brazil has some serious opportunities coming up to show off the Estadio Nacional de Brasilia stadium in the middle of the capital. The stadium is getting quite the upgrade, and by the time it’s finished, will reach LEED Platinum certification and become the first net-zero-energy stadium in the world.
Designed by Castro Mello Architects using Autodesk software, the stadium will be the second-largest World Cup stadium, with a seating capacity just over 70,000 seats.
The stadium will be powered by a ring of solar photovoltaic panels on the roof, and new net-metering legislation will allow it to shift between panel and grid power as needed. A photocatalytic membrane will also be installed on the roof to capture air pollution and break down the chemicals, and remove some C02 from the air. This is particularly noteworthy because more than half of CO2 emissions related to the stadium come from travel to and from the location.
The architects are also hoping to reduce vehicular travel to the stadium, installing 1,000 bicycle parking spots inside, and a total of 3,500 on the grounds.
There will also be rainwater collection and recycling systems inside the stadium for landscaping use, and all water fixtures will be low-flow. The design will take advantage of natural light while still providing ample shade from the sun.
To top it all off, the new design will be constructed using materials from the old stadium.
This is all expected to cost over $400 million, but a return on investment is expected come in about 10 to 12 years from the solar panels at least, which are expected to last at least 25 years. Construction is scheduled to be completed at the end of the year.
