Underground parking is sized separately from warehouses and offices. Day-to-day duty is diluting exhaust (CO and other gases) and killing dead pockets between aisles. Fire mode is smoke extract — different airflow, fans and dampers.
A common layout: supply/exhaust by floor volume plus ceiling jet fans that push air toward extract shafts. Without jets, one big roof fan leaves gas pockets at far walls.
CO sensors and controls are the operating logic — fans should not run 24/7 at full speed. Setpoints, standby and fire-alarm interlock belong in the design, before bay markings make rework expensive.
Aurum Prodest designs and installs parking ventilation: in-house ducts, shafts, jets, controls and commissioning, with general and smoke modes coordinated.
