During the Olympic and Para­lympic Games in Rio de Janeiro, around 18,000 athletes and others involved in the Games will be living in Ilha Pura, the Olympic Village in the Barra da Tijuca neigh­bor­hood. The 31 build­ings with a total of 73,359 m2 resi­den­tial area are divided into seven complexes. Each of the complexes features an under­ground garage with between 270 and 450 parking spaces.

To keep the air in the parking levels as clean as possible, a total of 138 effi­cient and quiet HyBlade® EC axial fans take care of the required incoming and exhaust air. The sensors that measure the carbon dioxide and carbon monoxide levels in the air in the garages can control the amounts of air exactly as required.
