This is the first activity of EDNA’s workstream on the energy efficiency of data centres.  It’s objectives are to:

• Assess the various definitions and classifications of data centres and energy efficiency metrics.
• Propose a definition of scope and a classification of data centres, suitable for policy measures on energy efficiency.
• Identify trends in data centres, including the main components that constitute a data centre, related to energy efficiency.  Where applicable, relate trends to the proposed classification.
• Assess the data availability (both in current practice and in future and including amongst others the measurability) for the metrics discussed in the previous EDNA project on Data Centre Metrics as well as for the proposed classification, including an assessment of the quality.

A report was published in February 2023.
