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

Uptime's global survey reveals some global trends

Power usage effectiveness (PUE) improved rapidly at first. Now it has hit a plateau

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

DCValley strongly focuses on the Energy Re-use Factor (ERF)

How to avoid common mistakes in measuring PUE

To get real efficiency figures, you need accurate measurements

Data center builders and operators must work together on efficient, sustainable practices

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

In response to the news that ASHRAE has abandoned plans to specify efficiency levels for data centres

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
