The legendary Maracanã stadium stages the decisive matches of the football tournament and two of the Games’ most striking moments: the opening and closing ceremonies. The stadium was recently modernised for the 2014 World Cup.
The long list of upgrades to the iconic venue includes the installation of world-class rainwater harvesting system and an enormous bank of solar panels. In addition to the energy efficiency and water savings, the Maracanã stadium has further polished its green credentials by reducing CO2 emissions, responsible for greenhouse gases, improving the local environment and optimizing use of construction materials.
The stadium’s sustainable performance saw it obtain a Leadership in Energy and Environmental Design (LEED) certificate seal from the US Green Building Council Brazil (USGBC). The LEED certificate seal is considered one of the foremost global sustainability ratings for buildings.To achieve the LEED certification, the Maracanã stadium was assessed in seven areas: sustainable space, water, energy and atmospheric efficiency, materials and resources, internal environmental quality, innovation and processes and regional priority credits.
An instantly recognisable feature of the upgrade is the approximately 2,500m² of photovoltaic panels installed around the stadium’s distinctive roof that can produce enough energy to power 240 homes and helps reduce the stadium’s power consumption.
A less conspicuous feature of the stadium is its impressive array of 18 massive rainwater harvesting tanks. The rainwater tanks are fed from the roof, which have been engineered to collect large amounts of rainwater for use in the stadium’s water systems, reducing its reliance on externally supplied water by 40%. The modular rainwater tanks supply water to irrigate the pitch, as well as for use in the 292 toilets and restrooms. The restroom facilities are also equipped with ecological flushing systems and intelligent faucets.
Sustainability seems to go hand in hand with the Olympic movement nowadays with each host striving to make THEIR games the greenest ever.
