A balancing act between data center energy, carbon, water, and heat reuse

Presented by Ewa Klimek (Roxtec) | Sean Barlett (Portacool)

This article focuses on recent developments in analyzing the interplay between water, heat, and energy in data center cooling system designs. The paper discusses how this relationship is exhibited when comparing key data center performance and environmental metrics. Key elements of this work include (1) the relationship between cooling system energy efficiency and water consumption, (2) the role of geographical location on energy efficiency, water consumption, and environmental burden; and (3) that holistic analysis of water consumption, carbon footprint, and water scarcity footprint should be considered concurrently. The use of waste heat is encouraged for reducing holistic environmental burden. A metrics calculation scheme with examples is provided with the intention of industry adoption for aiding in site planning for new data centers.
