What car park ventilation involves
Approved Document B sets out ventilation provisions for enclosed car parks, commonly 6 air changes an hour for normal use and 10 in fire conditions where mechanical ventilation is used. CO detection lets the system run at low speed most of the time and boost when pollution rises. Smoke control aspects are designed with the building's fire strategy and fire engineer.
Jet fan systems
Ceiling-mounted fans moving air towards extract points.
Ducted extract
Traditional ducted systems where layout suits.
CO and NO2 detection
Sensors and controls for demand-led running.
