Reason for Mitigation:
Provincial ordinance; Compliance with local regulatory limits for exterior noise emissions
Once the design was complete, our agile engineering and trades team completed the full turnkey delivery of the new silencer arrangements. This required close coordination with hundreds of other contractors working on-site to avoid facility start-up disruptions.
We implemented a custom baffled plenum silencer to mitigate discharge air noise from the air handlers.
The design required close collaboration with the equipment OEM to ensure the equipment functioned and remained serviceable after the addition of our sound attenuation components. This included integration of the AHU’s weather hood and modulating damper assembly to the new silencer design. To support the additional gravity and wind loads, our structural team coordinated a low-profile structural solution that embedded into the body of the AHU to conserve space between the units.
To accommodate the positioning of the AHUs (which were situated partially outside the building), the custom design incorporated an offset in the plenum and baffled sections to maintain airflow and maximize acoustic performance. We then worked closely with the building envelope designer to ensure the delivered solution was watertight.
The end solution was closely coordinated within the site BIM model by the Parklane CAD Team to ensure all major site integration elements were addressed.
