Concerns regarding the environment, energy efficiency, and compute density are playing a big role in the future of HPC facilities and data center designs. Liquid-cooling is an order of magnitude more efficient at cooling IT equipment, and as such, it is becoming an integral part of future strategies and a valuable alternative to air-cooling for existing data centers.

This paper describes the whole-systems approach and CEDaCI project outputs, including bespoke Eco-design guidelines, strategies, and digital tools to extend product life and recycling, and enable better decision-making to increase circularity in the DCI, prepare and support implementation of the EU Circular Economy Action Plan and ensure a secure, sustainable resource supply chain.

Small-scale data centers suffering from low cooling efficiency consume an intense power for reliable operation of IT equipment. In this study, thermal distribution in an air-cooled data center is simulated using an open source Computational Fluid Dynamics (CFD) model to examine the underlying mechanism that reduces thermal and cooling efficiencies. The numerical model is validated with the temperature measurements conducted in the data center.

This paper explores how transparency and open data can be a viable sustainability strategy for data centers and also shows how you can implement this strategy.

This document outlines the vision for a sustainable and accessible European cloud; one that will be open-source, fair, and create economic opportunities for all. Despite existing challenges, it is possible and  may soon become a reality. Such digital infrastructure will reflect European values and provide a blueprint that others around the world can draw inspiration from to further develop their own digital economies.

We welcome this opportunity to share our comments on this recast of the Energy Efficiency Directive (EED).

This paper is an output from our Steering Groups and sheds light on the opportunities and challenges to the genuine decarbonization of data centers.

Back-up power for data centers: A comprehensive study on the viability of batteries as the industry standard replacement for diesel generators.

Both energy and digitalization are on everybody's minds today. Both play increasingly important roles in our daily lives, yet few realise how interdependent these industries truly are. Digitalization promises to re-align our economy around data and computation, but the digital economy of tomorrow will be built on the shoulders of today’s electrical infrastructure. Fewer still can see the tremendous industrial and societal opportunities when two fundamental requirements of the digital age integrate.

In a joint statement of the SDIA with the Energieeffizienzverband für Wärme, Kälte und KWK e. V. (Energy Efficiency Association for Heating, Cooling and CHP - AGFW) and Bitkom e. V. we express the urgent need to adjust the definition of waste heat in the upcoming changes to the Combined Heat and Power Act (KWKG) in Germany in order to support the use of waste heat from data centers as a climate-neutral and sustainable energy source.
