Approved Document Part F covers ventilation of UK buildings. its primary focus is limiting moisture build up in order to prevent mould and potentially pollutants from filling the area. 

Compliance with Part F could generally be achieved by a mixture of natural ventilation and the installation of mechanical extraction units in bathrooms and kitchens. 

 

The simple answer is no.

Indoor air quality is a very complex issue that has been underesearched and has not been addressed barely at all with regards to regulations. There are multiple pollutants both outdoors (PM2.5, PM10, NO2, O3, etc.) as well as indoors (VOC, SVOC, VVOC, mould, formaldehyde, radon, allergens, etc.) that could affect our health. A proper ventilation strategy consists of four steps:

  1. Minimising source pollutants (critical)
  2. Designing an appropriate ventilation strategy 
  3. Increasing indoor air quality through filtration 
  4. Providing a constant circulated of filtered fresh air, whilst removing stale polluted indoor air

The underlying assumption of Part F is that the outdoor air is ‘fresh’ and ‘clean’. Numerous articles have proven this not to be the case, therefore we are not keen to provide advice on just compliance with Part F. Our Director is involved in several indoor air groups (UKIEG, CIBSE Indoor Air and ASTM D22.05 Indoor Air) and is a very strong supporter of creating better environments for individuals. 

Consultergy believes that when it comes to ventilation and healthy indoor environment, compliance is simply not good enough. If you want to provide healthy buildings and improve the quality of life of people, contact us to find out the most suitable ventilation strategies for your development.
