Learning Objectives:

  1. Identify the various organizations that create data center energy efficiency metrics and standards.
  2. Describe the fundamental concepts and functions of the metrics and standards used by ASHRAE, Energy Star, and The Green Grid.
  3. Explain how the metrics and standards of these organizations differ in their terminology, measurement methodology, and applicability.
  4. Infer how these metrics and standards impact the design and operation of data centers.

Electrical power is the linchpin for practically everything we do at home and at work — from watching TV to saving lives. It is so prevalent that it is often overlooked and taken for granted. Likewise, virtually all of the critical infrastructure that supports our everyday communications, security, and business operations is directly or indirectly dependent on data centers.

Over the past decade, both the number of data centers in existence and the power they demand have increased exponentially, resulting in an emphasis on energy efficiency. Concerns about climate change have honed in on the massive amounts of energy and water these facilities consume.

In the U.S., there are there are multiple overlapping data center energy efficiency metrics and standards, such as ASHRAE, Energy Star, and The Green Grid, to name a few. While they are similar in their overall intent, they differ in their terminologies, methodologies, and applications.

This webinar will examine and compare these differences to determine how they impact the design and operation of data centers.
