Acoustic, Ventilation & Overheating Assessments

Acoustics, Ventilation and Overheating strategies are all intrinsically linked. The majority of ventilation and overheating strategies rely on facade openings, which often inherently let outside noise in. It is, however, a common misconception to assume ventilation strategies involve a partially open window.

We are experts in acoustics, ventilation and overheating design. Our Director and co-owner, James Healey, co-authored the national guidance documents the Acoustics, Ventilation and Overheating: Residential Design Guide (AVOG) and the Guide to Demonstrating Compliance with the Noise Requirements of Approved Document O

We provide noise surveys and noise exposure assessments based on current best practice. We use these assessments to provide a Good Acoustic Design approach, in accordance with ProPG.

Given our experience, we understand ventilation and overheating air flow terminologies such as equivalent area and discharge coefficient, and we understand sound insulation terminologies such as sound reduction and element normalized level difference.

We consider noise inside dwellings both in terms of year-round ventilation based on the standards of Approved Document F and summer period overheating based on the standards of Approved Document O and/or the AVOG, utilising our unique and unparalleled industry-leading knowledge of residential ventilation and overheating. 

We work closely with our partner company, UK Overheating, to develop a single, coordinated overheating strategy that is optimised for the best passive overheating solutions wherever possible.
