Data Center Sustainability Metrics and Standards Quiz
In the U.S., 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.
Test your knowledge on industry’s sustainability metrics and standards with this quiz from Kohler. To earn CEUs, view the webinar before completing the quiz.
