Quiet, Cool, and Conserved: How We Brought Silent Climate Control to Oxford’s St Anne’s College Library

When you walk into a library, you expect quiet. But in modern design, achieving both acoustic stillness and perfect thermal comfort is an engineering tightrope. Traditional air conditioning is noisy, drafty, and visually intrusive—often relying on bulky ductwork and grilles that ruin clean architectural lines.
This was the exact challenge at St Anne’s College Library, Oxford.
With its massive volumes of books and a constant flow of focused students, the library required a delicate touch. The solution? A state-of-the-art BASWA Cool installation by Arthur Acoustics.
Here is how we combined acoustic luxury with invisible, eco-friendly cooling, and why this technology is rapidly becoming the future of modern building design.
The Oxford Project: Silent, Invisible Climate Control
At St Anne’s College, we installed BASWA Cool—a dual-function premium ceiling system that integrates high-performance radiant temperature control with world-class, seamless acoustic plaster.
Instead of blowing dry, noisy, recycled air around the library, BASWA Cool relies on capillary tube mats embedded directly within the acoustic plaster layer.
How it works: Chilled (or warm) water circulates silently through a dense network of micro-tubes close to the ceiling's surface. It cools the space via gentle radiant heat exchange—just like the natural cooling sensation of stepping into a stone cathedral.
The Acoustic Benefit: Despite housing this active thermal system, the ceiling retains Class A sound absorption (absorbing up to 90% of ambient noise), keeping the library pin-drop quiet.
The Visual Benefit: Completely monolithic, jointless, and smooth. No grilles, no bulkheads, and no ugly plastic AC units.
Beyond BASWA: Capillary Cooling is More Flexible Than You Think
While the St Anne’s College installation utilized the premium BASWA Cool acoustic plaster system, capillary cooling technology is incredibly versatile. At Arthur Acoustics, we can tailor this silent cooling method to fit the unique DNA of almost any property:
1. Integrated into Standard Plastered Ceilings
You don’t necessarily need a specialist acoustic ceiling to enjoy the benefits of radiant cooling. We can install the capillary tube mats directly onto standard plasterboard or concrete ceilings and render traditional plaster straight over them. The system is completely plastered over, leaving you with a perfectly flat, traditional painted ceiling that secretly keeps your room at the perfect temperature.
2. Paired with Stretch Fabric Systems
For a highly modern, minimalist, or geometrically complex space, we can combine capillary cooling with our premium stretch fabric ceiling systems. The fabric hides the cooling mats perfectly while allowing the radiant temperature to transfer effortlessly into the room, all while offering incredible, sleek visual aesthetics.
The Green Revolution: Why Capillary Cooling is Replacing Air Conditioning
The era of traditional HVAC is shifting. In fact, due to high energy consumption and harmful chemical refrigerants, traditional chemical-based air conditioning is facing strict regulations and outright bans in several countries and progressive urban zones globally.
Capillary cooling is the ultimate, future-proof alternative:
Incredibly Eco-Friendly: Because water transfers heat far more efficiently than air, capillary systems operate at much milder water temperatures (requiring less energy to cool). This significantly slashes a building’s carbon footprint.
Healthier Air Quality: Traditional AC units draft dust, pollen, and allergens around the room. Radiant cooling has zero drafts, meaning cleaner air and a healthier indoor environment.
Zero Noise: No fans, no rattling compressions—just absolute, uninterrupted silence.
