Oracle has again been acknowledged as a leader in data center energy conservation. Earlier this year, our energy efficient data centers gained accolades by the U.S. Environmental Protection Agency (EPA) and the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE). The momentum continues with our data center team’s latest win, achieving a prestigious award by DatacenterDynamics in recognition of Oracle’s “Breakthrough Innovations in Large Data Center in Cold Climate” within the Mega Data Center category (net IT load capacity greater than 1 megawatt). During the awards ceremony in New York City on December 2, DatacenterDynamics presented Oracle with this award to recognize our innovation, leadership and best practices in this important category.
We earned this achievement primarily by our innovative approach to cooling data centers using outdoor cold air – also known as air-side economization – which many have been reluctant to adopt in the past. The conventional approach to humidifying large quantities of air requires injection of steam into air whose generation requires energy. The industry learned quickly that it required more energy to humidify dry outdoor air than the energy saved from the use of its free cooling, and air-side economization did not make much headway in data centers. These problems were addressed efficiently in an innovative system installed in one of Oracle’s new state-of-the-art data centers in West Jordan, Utah. The innovation centers on the use of waste heat from the IT equipment for space humidification in the winter; evaporative cooling in summer; reduced primary airflow to the IT equipment; strategic hot air separation with recirculation; and novel controls that enabled the data center to achieve very high cooling efficiency at a lower initial investment cost. With efficient operation and low operating Power Usage Effectiveness (PUE), the system is expected to save over 41,000 MWh a year and the equivalent of 37,000 metric tons of carbon dioxide annually compared to an average efficient data center. More information on the project details can be found in our new whitepaper on data center cooling design.
Customers can learn from Oracle’s best practices on how to construct, manage, and build their own efficient data center, as well as run their applications on Oracle's public cloud and take advantage of Oracle's power usage effectiveness.
