REI cuts cooling energy use by 93%
A retrofit of outdoor gear, footwear and apparel retailer Recreational Equipment’s (REI’s) data centre has resulted in a 93% reduction in the cooling energy used to operate the Seattle-based facility.
The data centre houses servers and backup systems for computers, software systems, REI.com and point of sale for its 132 stores in 33 states. The retrofit uses “free cooling” via a rooftop evaporative cooling tower to keep servers at optimal temperatures. The system reduces the need for mechanical cooling almost all year round, or approximately 8,672 hours each year.
The retrofit has saved enough to power six REI stores at 2.2 million kilowatt hours each year. Improved efficiencies also mean improved business resiliency and stability in the event of a regional power outage.
The retrofit also includes upgraded backup battery banks, the removal of old power distribution units, the installation of floor brush barriers and curtain systems to contain cold air in critical areas, upgraded software to the backup power systems and rewiring subfloor cabling to optimise airflow under the raised floor.
“By examining our operations through a sustainability lens, we’ve achieved financial and environmental benefits and met our goals to increase efficiency, minimise disruptions and reduce our carbon footprint,” said Kirk Myers, REI corporate social responsibility manager.
“Being a good steward is reflected in how we care for the places where we play and work. We hope our actions show this is possible and financially prudent, and inspire others to actively manage their energy use.”
