Trends in Data Center Design – ASHRAE Leads the Way to Large Energy Savings ASHRAE Conference, Denver Otto Van Geet, PE June 24, 2014 NREL/PR-6A40-58902 NREL is a national laboratory of the U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy, operated by the Alliance for Sustainable Energy, LLC. Data Center Energy Data centers are energy intensive facilities. • 10-100x more energy intensive than an office • Server racks well in excess of 30 kW • Surging demand for data storage • EPA estimate: 3% of U.S. electricity • Power and cooling constraints in existing facilities.
