The LEED seal is used in over 140 countries and is awarded to sustainable construction enterprises

#A solar power plant (in the lower right corner) supplies 30% of the energy used by the Pernambuco ArenaThe Pernambuco Arena, stage to five matches of the FIFA World Cup Brazil 2014 located in São Lourenço da Mata (Recife metropolitan area), is now internationally recognized as an ecologically sound project. Reuse of rainwater, building automation systems and a solar power plant were some of the initiatives that allowed the project to obtain LEED Silver certification, a seal used in more than 140 countries to identify construction projects as sustainable. The assessment method used to grant the certification is developed by the United States Green Building Council-USGBC.

Energy efficiency initiatives have also been taken into account for the certification, including the use of an LED big screen and a solar power plant with 3,652 photovoltaic solar panels that can generate 126,480 kWh of electricity per month. The stadium's solar plant is the first photovoltaic solar energy system deployed in the state of Pernambuco. It supplies 30% of the stadium's energy and is located in a 15,000-m² area next to the Arena. The plant is part of the Strategic Research and Development Project developed by Brazil's National Electric Energy Agency (ANEEL).

The energy savings are also increased by the stadium design's favoring of natural lighting and ventilation schemes. The roof and side closures the stadium capture rainwater, and its wastewater is treated for reuse.

Practices and techniques

Besides these aspects, the certification process also recognized other practices and techniques adopted by the Odebrecht Infraestrutura developer to reduce environmental impacts during the stadium's construction. For instance, 24% of the inputs used were recycled (especially steel and cement). The use of materials and technologies with low environmental impact and the social, cultural and economic development of the surrounding region were also areas of priority for Odebrecht. A total 31% of the materials used in construction were provided by local suppliers.

LEED

The Leadership in Energy and Environmental Design (LEED) Certification is a system that rates buildings in different categories based on environmental sustainability criteria. The seal is used in 143 countries to encourage the transformation of building design, construction and operation actions in order to focus on the sustainability of initiatives. The LEED certification process takes into account specific dimensions of buildings, which are divided in prerequisites (mandatory practices) and credits, as well as recommendations that guarantee more 'points' to the building if met.
