Overview

This guide has been superseded by BG 46/2022 Domestic Ventilation Systems - A guide to measuring airflow rates

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.

This BSRIA guide was first published in 2013 (BG 46/2013), describing the conditional and unconditional methods of airflow measurement. The 2015 edition also describes a third method, the minimum benchmark method.

Contents include:

  • Types of ventilation systems
  • Performance requirements
  • Design and installation
  • Airflow measurement – conditional, unconditional and minimum benchmark methods
  • Testing and commissioning

The test work to support the methodology recommended in this guide was undertaken independently by BSRIA. Read report
