BSRIA has published the third edition of its Domestic Ventilation Systems guide, which takes into account revised guidance and provides more detailed information about equipment calibration.
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 Building Regulations requirements for ventilation in England, was published in 2021 and came into effect on June 15 this year. A version for use in Wales, providing the same guidance, was published in 2022 and will come into effect on November 23.
The updated guide is available from the BSRIA Bookshop, with free downloads for BSRIA members.
