How to set up a green data center
Establishing a green data center involves 7 key steps:
Energy audit
Assess your data center’s current power usage effectiveness (PUE) and carbon usage effectiveness (CUE). These metrics help to identify areas to optimize energy usage and reduce emissions. This allows your company to see where it can improve and set realistic goals.
KEY TIP: Calculating your PUE requires dividing your data center’s Total Facility Energy by its IT Equipment Energy. A score between 1.0 and 1.2 is efficient, while a score above 2.0 is inefficient.
Total Facility Energy = All the power consumed by the building, including cooling, lighting, and power
IT Equipment Energy = Power used only for computing, storage, and networking equipment
Switching to renewable energy
Companies should explore options for integrating renewable energy sources into their energy mix. Good examples are solar panels or wind turbines. Renewable energy reduces the use of fossil fuels and finite natural resources. It may be an expensive investment at first, but in the long run it will save your company money.
Implementing efficient cooling solutions
Companies thinking about going green should invest in advanced cooling systems. These include liquid and free cooling. Energy-efficient cooling systems reduce the power consumption associated with traditional air conditioning.
Optimizing server and network use
Businesses should consolidate workloads to maximize server efficiency. This reduces the number of servers needed and, by extension, the energy they consume.
Optimizing your enterprise network also improves performance and connectivity, minimizing downtime and ensuring efficient operations. This means more tasks can be performed using less time and energy.
The company therefore avoids excessive use of power and money.
Regular maintenance and management
Data center maintenance keeps your assets working at their best. It also prevents inefficient equipment wasting power and avoids unnecessary replacements of repairable assets. This means less ore-mining and less e-waste in landfills. Companies like Evernex can help your company with this.
Green building design
Companies which are constructing a new data center should consider eco-friendly building materials and designs. Sustainably designed facilities promote natural light and airflow. They therefore use less energy both for light and temperature control. Sustainable design thinks about the long-term plans of your company as well as the good of the planet.
Using refurbished part replacements
Extending the lifecycle of both your IT assets through part replacement delays its retirement, while using refurbished components also gives a second life to those assets and supports the circular economy.
Cooling technologies: a key for your green data center
Keeping data centers cool is vital to avoid overheating and breakdowns. However, traditional methods of cooling a data center are power-intensive. New cooling technologies are a breakthrough for making data centers more sustainable.
Liquid cooling
Liquid cooling uses water to lower the temperature of hardware and keep it stable. It does have certain risks, since water can cause problems for electrical equipment if there is a leak. It also requires certain maintenance processes. However, this method has a lot of benefits, such as energy efficiency and a high cooling capacity.
Free cooling
Free cooling earned its name because it does not cost extra money. This method lets cool external air into the facility and lets out the waste heat created by the data centers. This naturally keeps the equipment at an optimal temperature.
One risk of this technique is the variation of external temperature throughout the year. Using free cooling all year round could be complicated. However, investigations into solutions for this problem are underway.
The design of a data center itself can also affect cooling. Alternating hot aisles and cold aisles in a data center layout promotes airflow and temperature control.
New cooling technologies in a nutshell
| Technique | Benefits | Risks |
|---|---|---|
| Liquid Cooling |
|
|
| Free cooling |
|

Either of these options is a more environmentally responsible alternative air conditioning, which uses a lot of energy. Liquid cooling and free cooling both keep your equipment at a stable temperature and save your company valuable energy.
What is greenwashing?
Greenwashing is when a company promotes a false or exaggerated image of eco-friendliness for profit. To avoid this trap, companies must ensure genuine sustainability.
Genuine sustainability is looking beyond marketing claims and verifying data centers are minimizing their environmental impact.
