Petroleum Geo-Services’ (PGS) new data center in Weybridge, Surrey, UK, has achieved a power usage effectiveness (PUE) of 1.17, which rivals some of the best results in the industry including Google, reports Greenbang. Legacy data center cooling systems average a PUE of 2.25, according to the Uptime Institute.
The data center’s high efficiency delivered a first-year energy cost savings of £650,000 (approximately $957,000), reduced power consumption by 6.7 million kilowatt-hours, and cut CO2 emissions by 2.9 million kilograms. The data center is expected to reduce power consumption by 15.8 million kWh and CO2 emissions by 6.8 million kg when the facility is fully deployed.
The data center is the first facility to adopt Keysource’s Ecofris technology, a new approach to cooling that can reduce the energy cost of operating data centers by more than 45 percent, according to the company.
The facility also has a Data Center infrastructure Efficiency (DCiE) measurement of 83.3 percent (PDF), where 83.3 percent of the total power being consumed by the facility is powering the IT equipment.
The Green Grid, together with several global government and industry groups including the EPA recently agreed to global data center energy-efficiency metrics centered on the PUE rating.
The PGS facility has been designed for 1.8 MW of IT load and can accommodate high-density HPC hardware at any rack position with rack power densities of 30 kW, which accommodates the 15-kW per rack specified by the PGS IT team, says Keystone.
The Ecofris cooling system doesn’t need to use additional chillers until outside temperatures reach 24 degrees C, which means that additional power for cooling is only needed for about 80 and 100 hours annually, reports Greenbang.
Keysource told Greenbang its fine-tuning process and advanced performance monitoring helped reach the annualized PUE of 1.17, which outperformed the design expectation of 1.2.
