In an effort to make data centers more energy efficient, ASHRAE has released “Green Tips for Data Centers.” The publication identifies techniques for optimizing energy efficiency in existing datacom facilities.

According to the American Society of Heating, Refrigerating and Air-Conditioning Engineers, many of the techniques can be implemented through operational changes, upgrades or modifications that require a relatively low investment and that cause little disruption to the existing operations of the IT equipment.

“The book has particular relevance right now since there is a significant focus on energy efficiency in data centers,”  said Don Beaty, co-founder of the ASHRAE technical committee responsible for the publication “While it is fun and exciting to look at how we can design new data centers to be energy efficient, the fact is that there are many, many existing datacenters in operation.”

Among the many tips included in the book are: optimize supply air temperatures, installing monitoring equipment, improving lighting efficiency, optimizing data storage, and improving transformer efficiencies.

“The tips provide insight into practical techniques that have proven successful in other datacom facilities and give owners and operators the confidence to implement similar techniques in their own facilities,” Beaty said.
