Greenbuild Ventilation Validation to Part F (2019) - Ventilation Validator

The 2019 revision of the Part F (Ventilation) of the Building Regulations has mandated that ventilation systems be checked by an independent third party for flow rates after commissioning, broadly following the guidance in IS EN 14134:2019.

GreenBuild is certified by NSAI for ventilation flow rate testing in homes, and ventilation validation. Our registration number is 1.92.001.

'Hole in the Wall' or 'natural' ventilation is not currently being tested as such but rather just inspected; other, mechanical, forms of ventilation are typically being checked to ensure that the flow rates are as commissioned and that they are also within the requirements of the Part F (2019).

Note that where 'natural' ventilation is being chosen for new homes subject to the 2019 revisions of Parts F and L of the Building Regulations, the intention is that the tested airtightness can't be worse than 5 m3/hr.m2, but importantly also cannot be better than 3 m3/hr.m2.

As of early 2020 the Ventilation Validation scheme is still not fully engaged with all types of ventilation systems, such as demand control or positive input; please contact us to discuss further.
