3423: Johnson Controls explains how data center cooling energy can be cut by 40% – Johnson Controls explains how the cooling energy of data center can be cut by 40%

In this episode of Tech Talks Daily, I am accompanied by Johnson Controls Todd Grabowski to unpack the physics, products and design choices that form the next generation of cooling of data center. It is a practical conversation that goes from chips and compressors to water, strength and land restrictions, and what it really takes to keep modern infrastructure on a scale reliable.

Todd brings three decades of experience on the table, along with a view of the first row of how Johnson Controls and the York Brand have retained their focus on energy efficiency, reliability and sustainability for more than a century. That lifespan is important when the market is moving quickly. He explains why cooling is now next to strength when the determining limitation for data centers, and why about forty percent of the energy of a facility can be spent on cooling instead of calculation. If you lead technology, finances or facilities, that only number must focus on the mind.

Todd runs through the YVAM platform of Johnson Controls and the York Magnetic Lager Centrifugal compressor in the core, with real numbers about what that means in practice.

Consuming less energy around forty percent than typical cooling equipment of the past five years and working in environmental conditions up to fifty -five degrees Celsius, it is designed for the reality of heter climates and denser taxes. The navy trolley of the powertrain is a nice turn, because it was initially designed for silent and high reliability conditions long before hyperscale data centers require the same requirements.

Sustainability wire throughout the discussion. Todd outlines how the company represents internal goals, while engineering solutions that reduce the use of customer sources. We discuss closed loop designs that do not use water, carefully selected coolants with ultra-loin warming potential on the earth and product footprints that take into consideration with carbon effects from the start. It is a handy memory that sustainability is a system problem, not a single function on a specification sheet.

I was especially interested in the three sources that Todd says that every modern cooling strategy must balance. Country, because you need somewhere to reject heat. Power, because every watt is pulled into cooling, is a watt that is not used for calculation. Water, because many regions are already under stress and consumption cannot be the answer. Good design weighs these factors against the climate, the workload profile and the operational model and then standardizes where possible, so that the same unit can be efficiently performed in Scandinavia or Dubai without special tweaks.

We also dig in what AI means internally for Johnson Controls. It is implemented in production lines, accelerating design cycles and improving the reliability of compressor and heat transfer models. This translates into market in a faster time and more confidence in performance. On the market side, Todd is clear that the demand was not mitigated. If there is something, efficiency tends to unlock more use cases, and the net effect is an increase in the workload and constant pressure on facilities to cool them effectively.

If your team is struggling with when you have to accept liquid cooling, how you can reduce PUE by means of smarter chiller choices, or how you can plan climate variability in a global footprint, this episode offers a fair, well-founded view of someone sent the hardware and lived with his considerations. It also acts as a quiet celebration of Engineering Ambacht. The kind that rarely achieves the headlines, but still supports everything we build in the AI era.
