TopicBytes and BTUS: Trends in Data Center Sustainability
Abstract:  In this talk we describe a holistic approach to data center sustainability at the U.S. DOE National Renewable Energy Lab, which recently completed a new warm-water, liquid-cooled data center. The new data center is designed for a PUE of 1.06, which would make it the most energy efficient in the world. In addition, the new chiller-less data center captures the waste heat generated by the HPC system and uses that as the primary heat source for the building office space and laboratories. Any waste heat not utilized by the building is dissipated via evaporative cooling towers, eliminating the need for mechanical chillers. These approaches manifest themselves in the integrated "chips to bricks" approach we took. Finally, the new data center costs less to build than comparable data centers and will be much cheaper to operate.


Steve is the Director of the Computational Science Center at the National Renewable Energy Laboratory in Golden, CO where he leads NREL's high performance computing, computational science, and energy efficient data center activities. Prior to joining NREL in 2002, Steve spent 10 years at the National Center for Atmospheric Research in Boulder, CO developing massively parallel climate models. Steve also worked at the NASA Ames Research Center in CA, and at GE's Global R&D Center, in Schenectady, NY. Steve earned his PhD in Computer Science from Rensselaer Polytechnic Institute, in Troy, NY and his MS in Computer Science and BA Mathematics from the University of Rochester, in NewYork.
