The Arena project is designed to be LEED certified, therefore the MEP and HVAC systems will follow energy efficiency recommendations.
FLEXIBILITY AND NATURAL VENTILATION
The unusual Arena´s bowl footprint, with four open corners, is the result of a design strategy allowing the solution of many issues, such as Arena capacity flexibility after 2014 Word-Cup and local environment.
Since the pitch needs to be built in a strict North/South orientation, to avoid glare on cameras during TV matches transmission, to optimize the natural wind flow and ventilation, the bowl corners were chopped out and substituted by landscaped open areas. Though the landscape is expected thermal convections to enhance natural ventilation.
This new equipment will have capacity for 42.263 spectators with flexibility for the reduction to 27.000 spectators by partial dismantling of the North and South grandstands and their roofs.
The external envelope façade is made by vertical steel porches, covered with waterproof PVC membrane combined with certified wood louvers, propitiating excellent cross-ventilation to the Arena.
LANDSCAPE
Water availability is not an important issue due to the location of this project, close to an important hydrographic basin well served by rivers. However, the Arena Pantanal project aimed for water conservancy and has three combined systems in order to reduce water consumption.
The rain water will be collected. The domestic waste water will be treated in a proper plant and all the saved and treated water will be used for toilets, football pitch irrigation and air-conditioned system needs. The pitch irrigation is almost a close-loop system. Those integrated systems will save more than 30% of water.
The Landscape area will be composed only by native species of “Cerrado”, Atlantic Forest and Amazon Forest, since this region integrates these three important Brazilian bio systems. This design party allows easy species adaptation, eliminating irrigation and represents an opportunity to explore environmental education and awareness.
Another positive aspect of the landscape is the Forest Recovery Area, which will receive almost 2.500 native species for the riparian area.
