Jack Harvie-Clark Apex Acoustics Ltd Creating a quality environment – acoustic comfort

What’s the problem #1? 7 m people “seriously annoyed” 4.2 m exposed to dangerous noise levels at night 2 nd highest environmental burden of disease

What’s the problem #1? Assume windows are open for the overheating assessment and Assume windows are closed for the noise assessment Using planning conditions to improve indoor environmental quality (IEQ) of new residential developments N Conlan, J Harvie-Clark, Apex Acoustics Ltd. Proc. IOA Vol. 40. Pt. 1. 2018

How can we understand the problem? Source: WHO Environmental Noise Guidelines for the European Region (2018)

Solution #1 December 2019 ?? 50 dBA Internal ambient noise level from transport sources 40 dBA 35 dBA LOAEL No Adverse Effect Duration for which Most of Rarely the ‘overheating the time condition’ occurs https://www.apexacoustics.co.uk/acoustics-ventilation-overheating-residential-design-guide-draft-published/

What’s the problem #2? Future Homes Standard out for consultation Noise level guidance currently omitted Respond Source: https://www.gov.uk/government/consultations/the-future-homes-standard-changes-to-part-l-and-part-f-of- the-building-regulations-for-new-dwellings

Solution to problem #2 Noise level limits for mechanical services Commissioning testing Source: https://www.apexacoustics.co.uk/how-loud-is-too-loud-noise-from-domestic-mechanical-ventilation-systems/

Conclusions: Address noise and overheating Specify noise levels & commissioning Respond to Future Homes consultation jhc@apexacoustics.co.uk Jack Harvie-Clark Apex Acoustics Ltd @JackH_C Creating a quality environment – acoustic comfort
