Data Centers: New Standard Targets Energy, Maintenance

  October 19, 2016

By Dan Hounsell

A newly published energy standard for data centers features a performance based approach that is more flexible and accommodating of innovative changes that rapidly occur in design, construction and operations in that industry.

ANSI/ASHRAE Standard 90.4-2016, Energy Standard for Data Centers, establishes the minimum energy efficiency requirements of data centers for design and construction, for creation of a plan for operation and maintenance and for utilization of on-site or off-site renewable energy resources.

High plug loads and rapidly advancing information technology make data center applications significantly different from their commercial building counterparts. Standard 90.4 specifically addresses the unique energy requirements of data centers.

Standard 90.4 is a performance-based design standard that offers the design components for mechanical load (MLC) and electrical loss (ELC). Calculations of the MLC and ELC are made and then compared to the maximum allowable values shown in the standard based on climate zones.
