With Brazil hosting the 2014 World Cup and 2016 Olympic Games, the country’s capital is looking to do some remodeling. The existing stadium, The Estádio Nacional de Brasília, will get a major upgrade when it reaches LEED Platinum certification and becomes the first net-zero-energy stadium in the world.
Designed by Castro Mello Architects, the stadium will feature:
- Solar photovoltaic panels on the roof that provide the stadium’s power. The stadium will be able to trade energy between the panels and the power grid as necessary.
- A photocatalytic membrane on the roof that captures air pollution as it falls, and breaks down the chemicals, removing them from the atmosphere. Because over 50% of CO2 emissions related to stadium operations come from transportation to and from the stadium, this makes this especially important.
- A rainwater collection and recycling system for landscaping use and low-flow water fixtures inside the stadium.
- Lots of natural light, 3,500 bike parking spots and material reused from the old stadium.
The stadium, planned to be completed at the end of the year, is expected to cost more than $400 million. Though the solar panels able to perform well for at least 25 years, they are expected to provide a return on investment in 10 to 12 years.
