25/6/19 - 2019 Part F - Ventilation Rates testing

According to the latest revision of the Building Regulations, Part F, 2019, testing will be introduced very shortly for ventilation rates.

Greenbuild has acquired the recommended testing equipment in the form of a powered flow hood and is actively preparing for the new regulations. The picture below shows how some extractors may need additional measures to allow testing to be carried out, especially if the external point cannot be reached. In that case bespoke hoods may need to be fashioned...its a learning curve!
