Part f ventilation

The following is information on Part F ventilation requirements.

The purpose of the Part P Ventilation regulation is to ensure 'adequate means of ventilation is provided for people in the building'.

According to the document, ventilation is the 'removal of 'stale' air from a building and replacement with 'fresh' outside air.'

By providing outside air to breath, ventilation assists in the dilution and removal of pollutants as well as reduction in humidity/condensation, which combined create a more pleasant environment and relief for asthma and allergy sufferers. In short, ventilation provides fresh, clean air reducing the health risks to people and protecting the building fabric from damage. More guidance has been given on ventilating '‘equivalent' areas instead of 'free' areas along with more information on mechanical and natural ventilation systems. Guidance has been given for ventilation of basements in houses and trickle ventilation for replacement windows. Appendices provide good practice on the installation of fans and the minimisation of pollutants entering buildings in urban areas.

In all cases, the ventilation system is only compliant with Part F when the installed performance meets the ventilation rates quoted in the document. This is tested in accordance with new European Standards detailed in BSEN13141 and prEN13141. To help achieve the required performance, the document provides guidance on the location of the ventilation devices in a room and the allowable controls including humidity sensors, occupancy/user sensors and detection of moisture/pollutants released. Vent-Axia products are tested for installed performance in our own on-site BEAB approved laboratory.
