Currently, we constantly hear the word "sustainability" on television, in conversations with friends or family, as we attempt to raise awareness about the need to reduce energy consumption, which ultimately translates to carbon footprint.

​  ​​Directive 92/ 75EC1 established informative energy consumption labeling.The directive was implemented through other directives. As a result, most appliances and vehicles must have a visible European Union energy label when purchased or rented.

We are all familiar with the A+++, A++, and similar ratings as appliance efficiency decreases, as well as the ECO label for less polluting vehicles.

As always, there are ways to achieve a better rating by using certain legal loopholes, which, in reality, end up offering a less attractive product. Thus, clarity and transparency have become well-established.

However, in our market, there is nothing truly in place as a benchmark to determine whether a data center is efficient or not.

We all know that metrics like PUE, DCIE, WUE, and others may seem like efficiency data, but they do not provide actual information about the sustainability of a data center.

In reality, the PUE is a metric to compare my data center today with what it could be in the future if I implement best practices, such as improved insulation, more efficient cooling equipment, better humidity control, etc.

Therefore, if we think that comparing the PUE of two data centers provides us with useful information, I regret to say it is not the case. The infrastructure, purpose, location, and requirements of different buildings are vastly different, making such a comparison not entirely useful.

We can continue to think that with a good LEED certification for the building and a good PUE, we are efficient and sustainable. However, the reality is that we are overlooking many parameters along the way that will reveal the true sustainability of a data center.

How can the PUE value be manipulated without making any changes to the infrastructure? It's not about manipulation, but we know that there are various types of PUE, which, in my view, complicate the comparison and avoid offering absolute transparency.

In recent years, we have experienced situations of very unstable energy availability, starting with the pandemic, then the war in Ukraine, the diplomatic conflict with Morocco and Algeria, and finally, the instability in the government of Niger.

Europe does not have guaranteed energy supply, and countries like Germany and Poland have suffered a harsh winter with the cutoff of gas supply from Russia.

In conclusion, we can continue with non-transparent practices or start thinking about a market that genuinely invests in sustainability.

In Europe, initiatives for the control and measurement of efficiency in data centers are slowly but clearly taking shape.

The UNE 50600 regulation is being enriched day by day with contributions to obtain better metrics to increase control and efficiency. Therefore, it is expected that the pressure from the authorities to improve this critical competence, which affects us all, will increase soon to achieve a more sustainable market and leave an economically viable but also environmentally healthy legacy for future generations.

Are you on board with this wave? Bjumper is. We are working to anticipate the imminent requirements that will be requested in our market.
