BREEAM Reduction of Noise Pollution
 When to consider
Ideally prior to any works starting on site, as background noise level must be measured and it is not always feasible to stop construction works on site so as to take "clean" measurements. Equally, it's high risk as plant will have been specified during RIBA Stages 3/4 which may not meet requirements, as the required noise ratings are unknown.
- Establish whether there are any noise sensitive receptors within 800m of the development.
- Establish whether there's actually any plant that makes any noise going in. It may be possible for an acoustician to confirm there's no external plant and no significant noise sources and award the credit by default.
- If there are plant and nearby noise sensitive receptors, ask whether a noise impact assessment has already been done (or will be done), eg. to satisfy planning.
- Obtain the noise impact assessment, which must clearly states background noise levels. Make sure this clearly states acoustician's details.
- Collect either a copy of calculations showing compliance, or details of recommended noise levels.
- Collect confirmation or a copy of ERs stating that contractor must provide additional attenuation if required background noise levels are not met.
- If detailed calculations were done during design stage, make sure the specified plant has been installed (site inspection, schedule)
- If not, get a copy of the testing report.
 Questions to ask while seeking compliance
 Tips and best practice
 BS7445 / BS4142
Many acoustic reports will state that the noise impact assessment has been done in accordance to BS4142 rather than BS7445. Please note, this is also acceptable, with confirmation of best practice testing from 7445, as per the knowledge base article:
 Typical evidence
Typically you will receive a Noise Impact Assessment report (or other relevant acoustician's report), which may well have been completed for the planning application. This shall demonstrate that the criteria will be met by stating the:
- measured background noise levels at the nearest noise sensitive receptors
- plant noise limits (LAeq) set at the nearest noise sensitive receptors to achieve the BREEAM credits/planning condition, OR the predicted noise levels (LAeq) of the selected plant at the nearest noise sensitive receptors.
- If accurate calculations were provided at design stage, you will only require robust evidence (site inspection/delivery note/schedule) showing the correct plant has been installed.
- If accurate calculations were not provided at design stage, you will need a copy of the Acoustician's test report, which show that the measured plant noise (with all plant running at normal duty) meet the criteria post development.
 Applicable Schemes
The guidelines collated in this ISD aim to support sustainable best practice in the topic described. This issue may apply in multiple BREEAM schemes covering different stages in the life of a building, different building types and different year versions. Some content may be generic but scheme nuances should also be taken into account. Refer to the comments below and related articles to this one to understand these nuances.
