When ASHRAE 90.4 was first published in 2016 there were concerns voiced as to why an energy standard was needed for data centers. The first part of this presentation will explain what ASHRAE 90.4 is and why it is needed. It will explain the reasons for the new metrics and how this works in conjunction with ASHRAE 90.1. The second part will be a demonstration of the calculations required to show compliance with the standard.
