Why efficiency in existing facilities has shifted from good intention to obligation

Airflow intelligence was built to close the gap between a facility's design PUE and its actual PUE. Clean air is what keeps that gap closed

With AI operations, efficiency isn’t just about how much energy you consume. Rather, it’s about how much compute you produce from it, making output a more meaningful measure of performance

Why the roof should be viewed as a strategic asset rather than a covering

Two data centers. Same power. Same PUE – very different outcomes

Germany’s Energy Efficiency Act, with its demands for a PUE of 1.2, has reignited a debate: can a data center be both highly available and highly efficient?

Quantifying liquid cooling’s impact on power usage effectiveness (PUE) and energy consumption when introduced to an air-cooled data center

For more than a decade, data centers have been getting warmer - was that a mistake?

Direct liquid cooling has enormous potential if the industry can get the chemistry right

Advances in data center cooling and power technology could seriously undermine PUE as a benchmarking tool and eventually spell its obsolescence as an efficiency metric

The Edge makes up a big part of the sector's growing energy demands. It's time to get smart about that

PUE is a simple metric, but now we've reached levels of efficiency where it could become counter-productive

Further sustainability gains may be lost through a narrow focus on PUE

Industry needs a greater understanding of the long-term implications of efficiency initiatives, to help avoid hidden costs further down the line

To get real efficiency figures, you need accurate measurements

The recession stopped the green data center movement in its tracks. Now it’s coming back, older and wiser, and without any new metrics

Chasing efficiency can make your facility less reliable, unless you can quickly move down the Universal Learning Curve

We hear data centers in the city of Beijing have to have a PUE of 1.5 or less. How will that work? 

Disparate environments require custom cooling strategies to maximize the parameters of infrastructure, environment, and equipment age

Small and medium sized data centers can calculate PUE without metering beyond the UPS

ASHRAE’s new data center building standard includes recommended PUE levels

Why change the Power Usage Effectiveness (PUE) metric? 

Giant data centers have an easier time with PUE, says Peter Judge
