ASHRAE International has released four new addenda to its energy conservation consensus document ASHRAE 90.4-2016 Energy Standard for Data Centers. This document establishes the minimum energy efficiency requirements of data centers for design and construction, for the creation of a plan for operation and maintenance and for utilization of on-site or off-site renewable energy resources.
It is a relatively new document more fully explained in an article published by ASHRAE in 2016 (Click here). The addenda described briefly:
Addendum a: Improves and clarifies some of the ambiguous and obsolete language of previous revisions
Addendum b: clarifies exactly how credit can be taken for renewables. The renewables credit is limited to 5% of the IT load in order to encourage renewable energy while still requiring energy efficient mechanical and electrical systems.
Addendum d: Is a response to a Request for Interpretation on the 90.4 consideration of Diesel-Rotary UPS Systems and the corresponding accounting of these systems in the Electrical Loss Component.
Comments are due April 19th. Until this deadline you may review the changes by CLICKING HERE
