Learn about advanced water efficiency metrics and sustainable cooling strategies for data center infrastructure in this 18-minute conference talk from the Open Compute Project. Explore how resource constraints drive data center development decisions and discover methods to optimize water resource utilization while balancing power and space limitations. Examine the WUE+ metric, a next-generation water efficiency measurement that expands beyond traditional Water Usage Effectiveness by incorporating embodied water from power generation, local water stress factors, and water reuse efficiency. Understand how this comprehensive approach provides a holistic view of data center water footprints, accounting for both direct consumption and sustainability across energy and cooling lifecycles. Discover the Water Usage Optimization Score (WUOS) as a simplified, location-aware alternative that adjusts traditional WUE measurements using local stress indices. Gain insights into data-driven decision-making processes that prioritize water conservation, particularly in high water-stress regions, and learn about implementing closed-loop cooling systems, renewable energy integration, and strategic site selection to build resilient and sustainable data center infrastructure.
