ATLANTA – Industry input is being sought for the fourth public review of a proposed data center standard from ASHRAE.

ASHRAE Standard 90.4P, Energy Standard for Data Centers, would establish the minimum energy efficiency requirements of data centers for design and construction and for creation of a plan for operation and maintenance, and for utilization of on-site or off-site renewable energy resources.

The standard is open for public comment from April 29 until May 29, 2016. To comment or learn more, visit www.ashrae.org/publicreviews.

“This standard impacts a specialized discipline so feedback from that industry is critical,” Ron Jarnagin, 90.4P committee chair, said. “The data center industry responded to the three public reviews thus far with more than 1,000 comments, which have guided us as we move toward publication. We are hopeful we will approve a final standard at the ASHRAE 2016 Annual Conference taking place this summer.”

Changes made as a result to the draft standard are:

  • Revised the definition of incoming electrical service point
  • Deleted exception 2 to 4.2.1.2, Additions to Existing Data Centers
  • Corrected equations in 6.2.1.1 and 6.2.1.2. to correctly express peak power in all cases
  • Deleted 3B Coast from Tables 6.2.1.1 and 6.2.1.2.  to ensure alignment with ANSI/ASHRAE Standard 169-2013, Climatic Data for Building Design Standards
  • Added section that describes the process for establishing Verification of Equipment Efficiencies to Section 6 and 8.
  • Corrected Equations in Compliance Section 11.2.1.
  • Revised Section 11.3, to indicate how compliance can be demonstrated through modeling of shared systems between ANSI/ASHRAE/IES Standard 90.1-2013, Energy Standard for Buildings Except Low-Rise Residential Buildings, and 90.4 spaces
  • Updated references in Section 12 for Standard 90.1 and ASHRAE’s “Thermal Guidelines for Data Processing Environments.”
