B Sky B, Brick Lane Best Value, Big Savings: Combined Acoustic Engineering & Consultancy Expertise The Challenge Star Refrigeration contacted our team for assistance with the proposed replacement of chillers at one of B Sky B’s premises. The existing chillers were situated on the roof and screened by acoustic louvres to provide airflow whilst achieving some attenuation. However, the chillers could not operate at full capacity due to the restricted airflow. Therefore, Star Refrigeration asked ACE/ ACC to design an acoustic solution that would provide sufficient airflow for the replacement chillers and also meet the local authority’s stringent acoustic requirements. Our Work We performed an acoustic survey to quantify the sound level produced by the existing chillers and to measure the chara
