What is Ventilation Testing?

Ventilation testing was introduced in 2010 as Part F of the Building Regulations to ensure new buildings are assessed for their practical performance of ventilation.

A ventilation test makes sure you correctly configure the ventilation systems in your building and that the air flow is of a high standard. Poor indoor air quality can make a dwelling an unhealthy environment to live in.

Ventilation removes the indoor air from a building and replaces it with fresh outdoor air, removing airborne pollutants, including excessive humidity.

How ventilation is tested

Building Regulations Part F requires that testing has to be carried out on three types of ventilation systems. These are

  • Intermittent extract fans with background ventilators, for example, extractor fans, and trickle ventilators on windows.

  • Mechanical Extract Ventilation (MEV). This can be a whole house system or specific to a room (kitchen, WC or bathroom), ducts extracting stale air.

  • Mechanical Ventilation Heat Recovery (MVHR). Similar to MEV except that it also supplies fresh air to all non-wet rooms. The heat from the stale extracted air is kept in the central unit and used to heat the fresh air from outside before it is supplied to the house.

An anemometer is used to measure an air flow rate in litres per second (l/s), according to the room type, different levels of flow rates are applied. For example, an office room with copier would require an extract rate of 20 litres per second whereas a toilet might require an intermittent extract rate of 6 litres per second.
