Highlight Project

The Estádio Nacional de Brasília Mané Garrincha project team is seeking LEED Silver/Gold Certification for the 2014 FIFA World Cup. A second certification, LEED Platinum, the highest prize in Green Building and the first for mega-sport stadium projects in the world, is expected after external site work is completed and PV Solar Panels are installed on the stadium's roof. The stadium will also serve as one of 4 host venues for soccer at the Rio 2016 Summer Olympic Games and as the opening ceremony arena for the Brasília Univesiade Games in 2019. The LEED Design Team is comprissed of Castro Mello Arquitetos and EcoArenas & Partners.

Environmental Performance Highlights (*to be completed):

*Energy: First Net-Zero Energy Stadium in the world. 2.0MW building integrated PV solar array will generate 2.9 mn kWh/year.

*Water: 100% of non-potable water needs (pitch irrigation, urinals, waterclosets and stadium washing) will be supplied through rainwater capture, treatement and reuse on site reducing overall water consumption by more than 85%. All landscaping species are native and adaptive and require no irrigation.

Design: 360 degree breathable façade provides natural ventilation during all seasons. Large white roof reduces heat island effect, protects the building from radiation absorption which in turn lowers VAC energy loads. Thermal comfort inside and outside the stadium is maximized through shading.

Located at city center with access to Public Transport & *Bike Valet Parking: Walking distance from the main hotel, residencial & business sectors of the city. 3,500 bike valet spots provided, more than in any other stadium in the world.

Bio Climatic Analysis

As with any EcoArenas project our design team started with a Bioclimatic Analysis. The results indicated extremely high solar incidence, light variable winds and low humidity conditions for most of the year. These environmental factors lead our team to design a breathable façade, a large white roof to protect the building and provide shading inside and outside of the stadium, and to create enough space to place a large solar array on the stadium roof. The combination of shading and natural ventilation in Brasília's dry climate led to terrific thermal confort results! We have recorded up to 7º celsius temperature difference from outside of the stadium, while in the sun, to interior shaded locations within the stadium's lower and upper seating bowls. Protecting the building from solar radiation in our estimation reduces overall cooling costs by more than 40%!

Overall Building Energy Performance

To reach higher levels of LEED Certification, our Design Team decided to pursue greater overall building energy efficiency with reduced energy consumption measures combined with the generation of renewable energy on site. The goal was to obtain all of the LEED energy efficiency and renewable energy points and to create th first Net-Zero energy stadium in the world. But to achieve this we need to be able to properly account for the energy generated on site, maintaining the "environmental attributes" of the energy produced.

New Net Metering Legislation

Storing solar power in batteries was not a financially viable option and because stadiums are "surge" buildings, consuming a great deal of energy and other resources in short periods of time, it became clear that only through exchanging energy with the grid, the stadium would be able to account for improved energy performance with solar energy generation during the day when much of the consumption would be occuring in the evenings. Our team began working with the Ministry of Energy of Brazil to pass net metering legislation for small scale solar energy generation. The law may become the greatest legacy of the 2014 FIFA World Cup.

Site Selection & Bike Valet

Selecting a site for a stadium is one of the most important environmental decisions to be made by a Client and its Stakeholders. Industry analysts indicate that more than 50% of emissions related to the hosting of an event are related to the transportation of fans to and from the facility. The Brasília National Stadium is located perfectly at city center, with ample access to public transportation and in walking distance of the two largest hotel sectors, and the largest business and residential sectors of the city.

In addition we have developed a comprehensive Bike-to-Stadium Program with 2,560 permanent bike valet parking spots in 8 Valet stations right at building entrance. A temporary Bike Valet location is available, when necessary, for an additional 1,645 spots. Given that the city of Brasília is very flat, has a large biking community, and that many residential neighborhoods are very close to the stadium we expect great results for our program!

White Membrange Roof

In addition to reducing heat island effect and reflecting solar rays, Brasília's roof membrane is layered with a TiO2 component. This thin photo-catalytic coat breaks down atmospheric particles through an oxidation process into ogranic materials and removes greenhouse gases from our atmosphere at the rate of approximately 100 vehicles per hour (in Brasília's case) that the sun is striking on the membrane surface. This process also has the added effect of doubling the durability of the membrane and maintaining it white, without the need of using water for cleaning. Rainwater simply removes the organic particles from the surface of the roof in a natural and maintenance free fashion.

Stormwater Design

Once external sitework is completed, after the 2014 FIFA World Cup, Brasília's award winning stormwater design will be executed. The design includes an integrated building + site system that will capture rainwater from the stadium's roof and entire site. Stormwater Quantity and Quality will be controlled via a network of natural bioswales that will connect to an external retention pond. From the pond naturally treated water will be pumped back into the stadium to be further filetered along with pitch water to then be used for the stadium's non-potable water needs: pitch irrigation, urinals, water closets and stadium washing. The result will be a total potable water consumption reduction of +85% and all non-potable needs will be met from the stormwater capture, treatment and reuse system.

Landscaping Design

A diverse porfolio of native and adaptive species, including many at risk of extinction in the Savannah region of Brazil (Cerrado), will be planted after the World Cup. The species will be carefully placed such that in every part of the site, and for every season, a particular species will be blooming. The objective is to create a beautiful, local biosphere that will attract flora and fauna year round. It will complement the city park, (Parque da Cidade), the largest urban park in Latin America, on the other side of the Monumental Axis (Eixo Monumental) and Convention Center. Additionall strategies include light colored paving with high SRI (Solar Reflectance Index), permeable surfaces, protected habitats and new open, green spaces.
