PART F VENTILATION TESTING
CONDUCTED BY EXPERIENCED ASSESSORS
Ventilation Testing, also called Extract Testing, is now a requirement for all new builds in the UK, as per Part F of the Building regs. The process involves evaluation of the mechanical air flow rates, taking things like trickle vents and extractor fans into account.
Why is it required?
It all boils down to the health of the building’s occupants. Builders have become comfortable with the requirements for achieving low air test scores, but this has increased the necessity to ensure correctly sized purpose ventilation systems are installed – which function as they should do. It’s all well and good to have a nice air-tight build which achieves a great air leakage score, but it needs to be properly ventilated or people will have breathing difficulties.
What’s more, if an extract unit is installed in a place where a lot of water vapour and pollutants are released, it needs to be removed to stop the spread to the rest of the building. Long-term impacts of dampness and mould can have serious effects on a person’s health, as we touched on in this article:build tight, ventilate right.
How can you help to Achieve Compliance??
There are a few ways you can help to achieve compliance with the regulations to avoid reruns and hold ups in the process. Before the test:
Ensure that all trickle vents are installed correctly. Ideally, there should be one trickle vent per window and two for double windows
Ensure that all extractor fans and cooker hoods are functioning correctly – if they’re faulty, the testing becomes a lot more difficult
Check that there is at least a 10mm undercut for each internal door
