Domestic Ventilation Systems - a guide to measuring airflow rates (BG 46/2022)
Domestic Ventilation Systems - a guide to measuring airflow rates (BG 46/2022), was published by BSRIA in September 2022. It was written by Alan Gilbert & Chris Knights.
With the improvements in dwelling airtightness over the past few years, and increased use of systems such as Mechanical Ventilation with Heat Recovery (MVHR), getting the ventilation right in dwellings has become more critical.
In 2010, a requirement for mechanical ventilation air flow rate testing in dwellings was written into the England & Wales Building Regulations. A new Approved Document F Volume 1, providing guidance on meeting the Building Regulations requirements for ventilation in England, was published in 2021 and came into effect on 15th June 2022. A version for use in Wales, providing the same guidance, was published in 2022 and will come into effect on 23rd November 2022.
