Zayo is saving five million kilowatt hours of electricity a year at three of its US data centres – potentially reducing its expenditure by an annual $500,000.
The company is saving the power thanks to a building
management system that makes the data centres, in Atlanta, New
York and Dallas, Tier 3 compliant.
Zayo has worked with Fairbanks Energy Services on the project,
said Jenny Gerson, its senior director of sustainability and
strategy. "Fairbanks Energy has played an important role in
helping us meet our energy savings and cost reduction goals in
these three data centres. We look forward to continued
collaboration on additional projects."
The building management system integrates all of the power and
cooling systems. Fairbanks installed heat exchangers, automated
valves and new pumps. All of these changes were done live to
the cooling system without any interruption or loss of
redundancy, said the energy company.
CEO Adam Fairbanks said the work "is helping them meet their
sustainability goals while reducing operating expenses and
ensuring uptime, decreasing the likelihood of equipment
The energy efficiency impact of this site includes 4.4m kWh of
savings. In addition to the efficiency benefits, the data
centre was able to reclaim over 45% of stranded mechanical
capacity and now has the ability to scale to over 150 watts per
Zayo claims the total annual saving is 5m kWh. Householders
would pay around $600,000 a year for that at current US
electricity retail prices.
