Passive stack ventilation
Domestic Ventilation Compliance Guide, 2010 Edition (with 2011 amendments), published by the Department for Communities and Local Government in July 2011, defines passive stack ventilation (PSV) as: ‘…a ventilation system using ducts from terminals in the ceilings of rooms to terminals on the roof that extract air to outside by a combination of the natural stack effect and the pressure effects of wind passing over the roof of the building.’
Approved document F of the Buildings Regulations uses the same definition.
See also: Stack effect.
NB: Stack ventilation can also refer to secondary ventilation stacks used to overcome air pressure changes in pipework in high-rise buildings. For more information see: Secondary ventilation stacks in tall buildings.
