An underground parking garage with an area of over 9,500 m2 with 322 parking spaces has been completed in the center of Nijkerk, the Netherlands.
A reversible ventilation system for fire ventilation has been installed. The entire ventilation system is controlled by an automatic fire detection system. The fire detectors send a signal telling in which zone there is a fire alarm which starts the fire ventilation system. Each fan has a capacity of 90,000 m3/h.
For day-to-day ventilation, nine thrust fans and four axial fans have been installed.
