What is Ventilation Testing?
In 2010, Ventilation testing was introduced into Part F of the Building Regulations to ensure that all new dwellings are assessed for their practical performance of ventilation. Ventilation refers to the removal of indoor air from a building and its replacement with fresh outdoor air for one or more of the following reasons:
a) To ensure there is adequate provision of outdoor air for breathing
b) To allow the dilution of airborne pollutants, including odours
c) To control excess humidity (and prevent the build-up of mould)
d) To allow the provision of air for fuel-burning appliances
The key aim of the requirement of Part F is that a ventilation system, under normal conditions, is capable of limiting any airborne particles or pollutants within a building that could be hazardous to people’s health. Pollutants can vary depending on the purpose for which the building is being used. Industrial and commercial dwellings may have a far wider range of pollutants than say, those that are only used for domestic purposes.
How ventilation is tested
Part F of the Building Regulations requires that MHVR Systems (Mechanical Ventilation and Heat Recovery), MEVs (Mechanical Extract Ventilation) and intermittent extractor fans undergo a flow rate test to ensure they are working efficiently. Evidence of this test must be passed to the Building Control Body (BCB) as part of their sign-off procedure.
The assessment of ventilation is undertaken using an anemometer which measures an air flow rate in l/s (litres per second). Different levels of flow rate are applied to different rooms according to their purpose and the equipment within them. A toilet, for example, requires an intermittent extract ventilation rate of 6 l/s, where as a kitchen without a cooker hood would require one at 60 l/s. An office room with a photocopier would require an extract rate of 20 l/s.
