ASHRAE Releases Revised Version of Data Center Standard
Achieve energy efficiency while avoiding potential reliability issues
ATLANTA — ASHRAE released a revised version of its energy standard for data centers.
ANSI/ASHRAE Standard 90.4-2019, Energy Standard for Data Centers, establishes the minimum energy-efficiency requirements for the design and operation of data centers, with special consideration to their unique load requirements compared to other buildings. Standard 90.4 applies to data centers with a conditioned floor area greater than 20 W per square foot and IT equipment loads greater than 10 kW. It contains specific requirements for mechanical and electrical systems installed in new data centers or in data center additions/alterations that require new mechanical or electrical systems.
