Building Better Acoustic Neighbours
Building Better Neighbours: Modern Data Centres
Welcome to our first installment of Building Better Neighbours, a new series dedicated to exploring design choices that can help data centres become more welcome in their local communities.
As data centres surge in size, number, and power demand, they’re increasingly landing in places they’ve never been before—near homes, schools, and commercial districts. Today’s facilities are effectively AI factories, driven by unprecedented GPU‑based workloads that require massive electrical capacity, sophisticated cooling systems, and continuous airflow. This growth is colliding with community expectations for livable, attractive, and quiet neighbourhoods.
Cities and counties are responding with stricter zoning requirements, heightened scrutiny, and evolving sound ordinances—often leaving architects and engineers searching for strategies to make data centres not just permissible, but welcome.
This series explores practical, design‑forward ways data centre architects can create facilities that perform at hyperscale while integrating gracefully into the communities around them. We’re trying to build better neighbours. We’ll examine real site challenges and highlight product solutions that support airflow, aesthetics, and, in this first segment, sound attenuation.
The cloud is loud
Noise is one of the biggest friction points when data centres meet communities. Mechanical yards typically house cooling towers (85–95 dB), generators (90–100 dB), and transformers (70–80 dB)—levels well above the 55–65 dB that many residential ordinances allow. Municipal code often becomes even more restrictive between 10 p.m. and 6 a.m., where reductions of 10 dB or more are common in dense or mixed‑use markets. Without mitigation, these facilities can trigger complaints, legal challenges, or costly design revisions. The cost of downtime can quickly become a headache for developers.
Why is noise challenging?
Generator yards and cooling systems produce broadband sound across multiple octave bands, which means the ability to mitigate noise really depends on the octave bands you are addressing. Noise tends to refract and travel farther at night, and many data centre sites lack natural buffers such as large setbacks, mature vegetation, or acoustic mass from adjacent buildings. This makes engineered mitigation essential from day one.
Acoustic Louvres + screens
Acoustic Louvres are uniquely positioned to address two major challenges in data centres: airflow and sound control. They can be integrated into facades or deployed as freestanding screens on rooftops or equipment pads. Unlike solid walls— which can impede ventilation—acoustic Louvres maintain critical intake and exhaust paths while reducing sound transmission.
These products are engineered to perform differently at various octave bands, allowing architects to tailor attenuation to the specific frequency ranges produced by cooling towers, generators, or gas turbines.
At CS, we can engineer an acoustic solution to meet a project’s specification. If remediation is needed, rather than removing any vision barriers and starting over with a new structure, call us to explore adding acoustic solutions to the existing structure.
Looking (and listening) ahead
As data centres continue to scale and build closer to urban populations and residential communities, noise mitigation will remain foundational to community compatibility. Acoustic Louvres and screens provide a high‑performance solution that helps data centres stay compliant while helping neighbours sleep at night.
We are always listening (no pun intended) and ready to create better solutions. Bring CS your ideas! We would love to collaborate on better solutions for your data centre needs. Explore our solutions for data centres here.
