Background
Hollis Global commissioned Anderson Acoustics to support the refurbishment of Unit 17, Premier Park, Park Royal, London, targeting acoustics related credits under the BREEAM UK Refurbishment & Fit-Out 2014 scheme. The refurbished premises comprise general office areas, a reception, breakout spaces, WCs, and a plant room, all requiring careful acoustic consideration.
Challenge
To secure three BREEAM Hea 05 credits (acoustic performance) and one Pol 05 credit (reduction of noise pollution), the project needed to:
- Meet stringent sound insulation targets between sensitive spaces;
- Control internal ambient noise levels for comfort and productivity;
- Achieve optimal reverberation times for clear communication;
- Limit noise emissions from fixed plant to protect nearby residential areas;
- Demonstrate compliance both at design stage and through post-construction testing.
What We Did
Design Stage:
- We set bespoke acoustic performance standards in line with BREEAM, British Standards, and British Council for Offices guidance;
- Detailed design advice covered sound insulation for walls and floors, ambient noise level targets, and reverberation time criteria;
- Baseline noise surveys established external and internal noise conditions, informing robust design targets for both building fabric and services;
- Plant noise limits were set conservatively to ensure compliance at the nearest sensitive receptors, even before final plant selection.
Commissioning & Testing:
- Pre-completion testing was conducted, including airborne and impact sound insulation, internal ambient noise, reverberation time, and plant noise measurements;
- All tests were performed by UKAS-accredited consultants using calibrated, industry-standard equipment;
- Testing followed relevant ISO and British Standards methodologies to ensure accuracy and reliability.
Result
- All acoustic performance targets were achieved: Sound insulation, ambient noise levels, and reverberation times met or exceeded design criteria across all tested spaces;
- Plant noise emissions were well below required limits: Ensuring no adverse impact on nearby residential properties;
- Full BREEAM credits secured: The project is eligible for all three Hea 05 credits and the Pol 05 credit, supporting both occupant wellbeing and environmental responsibility.
Project Progress
The project achieved a BREEAM ‘Outstanding’ rating. The refurbishment is now completed. For more information head on over to Hollis’ website here
