A remodel of the Estadio Nacional de Brasilia
Stadium will bring seating capacity up to 70,000 seats. But this is not the
main aim of this soccer stadium. The developers of the project want to achieve
a higher goal: being the first LEED Platinum certificate stadium in the world.
To achieve that goal designers are working on green solutions to fulfill the requirements.
The developers are designing a number of elements
to get a LEED Platinum status:
- A ring of solar photovoltaic panels on the roof
provides the stadium’s power. Because of new net-metering legislation in Brazil, 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. Over 50% of CO2 emissions
related to stadium operations come from transportation to and from the stadium.
- VIP bicycle parking for 1,000 bikes inside the
stadium. There will be 3,500 bike parking spots in total.
- Rainwater collection and recycling system for
landscaping use, and low-flow water fixtures inside the stadium.
- Natural light - but also provide shading from the
hot Brasilia sun.
- Reused material from the old stadium.
Critiques:
Bike racks: Brasilia isn't made for bikes.
Very few people ride bikes there.
None of this comes cheap. The stadium is expected to
cost more than $400 million to complete. However the
solar panels, are expected to provide a return on investment in 10 to 12 years,
with a life cycle for the panels of at least 25 years.
