Draft Acoustics, Ventilation and Overheating Guide

The AVO Guide has been prepared by an Association of Noise Consultants (ANC) working group and has been published as a draft for consultation. The Guide is intended to contribute to the practice of good acoustic design, as emphasised in the Professional Practice Guidance on Planning and Noise (ProPG).

Objectives of the consultation

The AVO Guide is intended for the consideration of new residential development that will be exposed predominantly to airborne sound from transport sources, and to sound from mechanical services that are serving the dwellings in question. Although the policy coverage is limited to England, the approach may be applicable in other parts of the UK. 

The Guide includes:

  • an explanation of ventilation requirements under the building regulations and as described in Approved Document F, along with typical ventilation strategies and associated noise considerations;
  • an explanation of the overheating assessment methodology described in CIBSE TM59;
  • potential acoustic criteria and guidance relating to different ventilation and overheating conditions, for both environmental noise ingress and building services noise; and
  • a worked example of the application of the AVO Guide including indicative design solutions.

The consultation closed on 11 May 2018. The AVO Guide may be subject to change following peer review and further consultation with the ANC membership.
