One of the biggest stages of national passion hits a great goal in innovative and sustainable construction.
Inaugurated in 1950, the Maracanã Stadium was once the largest in the world and could hold 200,000 people at that year’s FIFA World Cup final. In addition to football teams, this lawn has hosted famous singers such as Madonna, The Rolling Stones, Tina Turner, Frank Sinatra and others. But it was in 1983 that Maracanã broke its audience record, receiving 250,000 fans of the rock band Kiss.
Sixty-four years later, more precisely in 2014, Brazil once again hosted a World Cup and Maracanã was the scene of several important games, including the final. To this end, the stadium has undergone extensive refurbishment to meet all the standards required by the organizing committee, including LEED® Certification.
The CTE Sustainability Unit offered LEED® Building Design and Construction Certification Consulting services, with the aim of making Maracanã a stadium recognized for its high environmental performance. The renovation followed the highest standards of sustainability excellence in the constructed environment, focusing on project development and construction work.
CTE participated from the beginning in the arena’s design and sustainable modeling phase to the delivery of the works, dealing directly with the entrepreneurs, designers and builders to achieve LEED® certification. The stadium has 98,776.13 m2, of which 26,026.18 m2 are newly constructed and 72,749.95 m2 have been renovated.
The LEED for New Construction certification in the Silver category, version 3.0, which has been granted by the United States Green Building Council (USGBC), evaluates and recognizes sustainable solutions and technologies adopted in the project’s construction process, aiming at reducing environmental impacts throughout the building’s lifespan. In addition, it ensures consistent management of the enterprise, based on equipment maintenance policies and processes, aiming at energy, water, waste and service management, such as cleaning and landscaping. The ultimate goal is to maximize operational efficiency and minimize environmental impacts.
- 23% reduction in operating cost with energy consumption.
- Reduction of 71.14% in potable water consumption (100% of the demand for toilets and urinals will be supplied with reused water) and 100% saving of potable water for irrigation.
Sustainable Differentials of Maracanã:
- The project has access to Maracanã Station (surface trains) already in more than 60 bus lines serving the stadium, reducing the impact caused by the use of cars.
- All parking spaces are located on the ground floor and are covered, reducing the heat island effects around the enterprise.
Rational use of water
- 100% reduction in potable water use for urinals and toilets.
- Considering other devices such as washbasin faucets, showers, service faucets and pre-rinse kitchen sprays, the reduction is of 71.14%.
- 100% of the water used for irrigation comes from rainwater.
Energy and atmosphere
- Total annual energy cost reduction of 23% as compared with the reference model.
- Installation of VRF system with air condensation, presenting reduction of HVAC energy consumption, due to the significant reduction in operating fans, thus requiring less air movement when compared to the chiller system with fan-coils and VAV boxes.
- Use of the efficient lighting system, reducing by 44% the consumption of energy with indoor lighting.
- Installation of 60 sets of photovoltaic plates, responsible for a production energy equivalent to 458,685.00 kWh / year.
Materials and Resources
- Easy access areas located on the ground floor were destined to the collection and storage of materials for recycling.
- A Recycling and Selective Collection Program was developed for user awareness, including internal logistics, transportation and final destination.
- 55% of the vertical structures, façades and fences existing in the original design were maintained, ensuring a significant reduction in waste generation caused by the renovation of the stadium.
- The amount (by volume) of waste diverted from landfills was 50%, excluding hazardous waste and soil / land.
Quality of indoor environment
- Thermal comfort parameters compatible with the parameters set out in ASHRAE Standard 55.1 – 2004.
- Accurate measurement of air supply systems, ensuring that the minimum air volume needed to maintain the quality of the indoor environment is provided to the occupants.
