Part F

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

Ventilation Testing

Key Aim

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, whereas 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.

Dan at enevo has completed for us SBEM Calculations and EPC Certificates for 6 commercial units on an industrial estate. The cost of the works was very competitive and the service we received was second to none. With very limited time to get these works completed Dan worked round the clock (and into his annual leave!!) to ensure that our completion date was achieved with very little notice. Would highly recommend!
