Suitable for new-build dwellings in England
Part F of the Building regulations 2010 requires that the practical performance of all ventilation systems in new dwellings is demonstrated through a robust testing procedure. This means all centralised and decentralised mechanical ventilation systems and extract fans should have their flow rates tested, with the results submitted to building control as part of building regulations sign off. The ventilation test therefore requires an on-site visit.
As buildings become better insulated and more airtight, it is now more and more important that they are designed to breathe, allowing fresh air in and water vapour out. If a building does not have sufficient ventilation it will suffer with condensation which can lead to black mould issues.
