While most people's eyes will be on the 22 players from Brazil and Croatia kicking off the 2014 World Cup, Hyewon Kong looks at how one stadium is leading the way on sustainable design.
This year's World Cup is special not just because the hosting country has won more World Cups than any other, but also because sustainability has been a critical point of contention in the build-up to the event.
Nowhere is this more clearly demonstrated than in the world's first net zero energy stadium, Estadio Nacional de Brasilia, which is also the first sports arena in the world to receive the platinum level (maximum) LEED (Leadership in Energy and Environmental Design) certification from the US Green Building Council.
This remodelled stadium uses recycled materials from the old stadium and will generate 2.5 megawatt of solar energy - enough to power the entire stadium with the remainder going back into the grid. This is more solar power than 11 of the 32 countries participating in the competition are generating. It also actively reduces emissions through a pollution absorbing roof membrane, and collects rainwater to be reused in toilets and cleaning.
The world's most sustainable stadium couldn't exist without the computer-aided design and simulation software, vital tools used by architects and engineers to transform their ideas into reality.
