Power usage effectiveness
Advanced ways to improve your data center’s PUE
A substantial part of a data center's energy consumption goes into cooling its servers. That makes picking the right methods and technologies for cooling, power distribution, and heat reuse critical for improving Power Usage Effectiveness (PUE).
Why data center Power Usage Effectiveness (PUE) matters
As our world is getting increasingly connected, the global need for data storage and processing is snowballing. By 2025, global demand will be an estimated 180 zettabytes – the equivalent of every single person alive today needing 48 laptops for data storage.
But a data center consumes significant amounts of power for cooling IT equipment. This makes the reduction of data center energy consumption an important battle in the world's green transition.
Power Usage Effectiveness (PUE) provides the data center industry with a metric to determine the power efficiency of a data center. Power Usage Effectiveness indicates how much of a data center’s total power usage goes to the center’s IT equipment alone.
To obtain a lower PUE takes a smart combination of methods and technologies. Below we offer insights and solutions regarding HVAC, power distribution, energy storage, and heat recovery that support a reliably high uptime and drive down power usage effectiveness.
Methods and technologies for improving power usage effectiveness
The green transition has industries across the globe working with improving energy efficiency. In the data center space, Power Usage Effectiveness (PUE) has become a focal point. Below, you can find insights on how to lower power usage with more efficient equipment, reuse energy consumed, and cut energy costs in any data center.
Learn how to optimize your data center’s Power Usage Effectiveness with Danfoss' EC+ concept and intelligent AC drives. HVAC/R experts Jesper Therbo and Peder Spek share their extensive knowledge on best-in-class energy efficiency solutions, intelligent heat management, and the Danfoss EC+ concept. You’ll also learn how to increase uptime with condition-based monitoring and avoid EMC and harmonics interference.
The demand for internet and smart technologies makes it vital that we reduce power usage in data centers and implement more efficient HVAC and power solutions to create data center sustainability and cut CO2 emissions.
Led by Paramasivam Shanmugam, Senior Manager-Power Electronics & Controls with Danfoss Drives, our webinar will provide an understanding of what harmonics are in electrical system and how VFDs helps to improve energy saving by mitigating harmonics.
In this session from the UK Buildings Festival 2021, in partnership with elemental, Jim McClelland, Jonathan Evans, Viktar Zaitsau, and Jakob Jul Jensen discuss whether cooling is the hot topic for data centers in the digital age.
There are significant opportunities for data centers to reduce their impact on the environment. In this video, Drew Turner and Adrian Vrinceanu offer an introduction to some of the solutions: Ensuring optimal thermal conditions around servers, optimizing building services, and recycling excess heat into district heating systems.

Cases on data center energy efficiency
Learn how other data centers have reduced total power usage and increased data center efficiency with Danfoss services and equipment.
A British manufacturer has recently installed a scalable data center together with one of their customers which has achieved an impressive Power Usage Effectiveness rating (PUE) of 1.21.
The installation consists of 6 phases each 500m² complete with 12 high efficient cooling units supplied by the British manufacturer. Each cooling unit has multiple inverter fans and compressors in order to increase efficiency and provide N+1 resilience.
When Facebook chose Condair to provide an evaporative cooling and humidification system for a massive new data center in Luleaa in northern Sweden, Condair called on Danfoss to provide the high-pressure pumps.
Not only must the pumps distribute up to 13,000 liters of water per hour – they also have to do it with zero risk of oil contamination to keep hygiene intact throughout the 28,000 m2 of the center.
