BREEAM FAQ's

Aim: To ensure the buildings' acoustic performance including sound insulation meet the appropriate standards for its purpose.

The information shown below is also available to download in spreadsheet format, and aims to help summarise the credits that your project could be targeting and is split into two tabs, one for BREEAM Health & Wellbeing Hea 05 credits and one for the BREEAM Pollution Pol 05 credits.

For the Hea 05 tab just select your building type from the drop down list and the relevant credit criteria and testing requirements are listed.

We hope you find the spreadsheet useful, needless to say HRS Acoustics and BREEAM staff are always available to assist with any queries you may have relating to BREEAM acoustic credits – or any other acoustic issues.

Room Function	Criteria	Credits	Testing Requirements	Notes
As required by relevant standard. (HRS Comment: Relevant standard as defined in criteria column)	Achieve the performance standards required by Building Bulletin 93 based on a sample measurement as described in Section 13 of Building Bulletin 93 and the ANC Good Practice Guide.	1	A Suitably Qualified Acoustician carries out pre-completion acoustic testing to ensure that the relevant spaces (as built) achieve the required performance standards. Where testing identifies that spaces do not meet the standards, remedial works are carried out prior to handover and occupation. Testing must be carried out in line with Section 13 of BB93 and the ANC Good Practice Guide recommendations. Remedial works must be carried out in line with the Section 13 of BB93.	None
As required by relevant standard. (HRS Comment: Relevant standard as defined in criteria column)	Rain noise - For roofs with a mass per unit area less than 150kg/m2 (lightweight roofs) or any roofs with glazing/rooflights, calculations or laboratory data are required for teaching/learning spaces to demonstrate that the reverberant sound pressure level in these rooms are not more than 20dB above the indoor ambient noise level for the equivalent type of room given in Table 1.1 of Building Bulletin 93 during heavy rain.	1	As above where applicable. Where is it not considered applicable a justification and alternative means of compliance should be provided by the Suitably Qualified Acoustician.	For heavy weight roofs, or parts of the roof that are heavyweight, with a mass per unit area greater than 150kg/m2 (inclduing those with sedum planting) that do not have any glazing/rooflights, calculations are not required, as such the credit can be awarded on a default basis of compliance For the purpose of assessing the reverberant sound pressure levels on rooms beneath light weight roofs and roofs with glazing and/or roof lights the levels should be calculated using laboratory test data from measurements conducted in accordance with BS EN ISO 140-18 2 'Heavy' rain noise excitation.
As required by relevant standard. (HRS Comment: Relevant standard as defined in criteria column)	All music accommodation (or multi-purpose halls in primary schools with no musci accommodation) is to meet the performance levels set within BB93. Where noise levels are expected to exceed 95dBA (e.g. in the case of amplified music and/or percussion) the design team must demonstrate that the need for higher sound insulation has been designed out through careful space planning.None	1	As above where applicable. Where it is not considered applicable a justification and alternative means of compliance should be provided by the Suitably Qualified Acoustician.	Whilst careful timetabling of lessons may also mitigate adverse acoustics issues, BREEAM's focus for new construction is building performance. Timetabling is likely to change over the building's lifetime, therefore, it cannot be used to demonstrate compliance with this criterion.
