Novel Data Center Cooling and Control Save Energy and Optimize Utility

U.S. energy consumption from information technology (IT) equipment has risen by ~36% since 2005, an increase driven by the growth of internet usage by individuals and businesses. Data centers provide the IT infrastructure, which totals millions of servers and computing devices for data processing and storage. The electricity consumed in these data centers is mainly by the equipment (50%) and HVAC (25%–40%) to maintain the computer room environment or computer room air-conditioners (CRACs). The increasing efficiency of computer equipment design and higher equipment densities has increased demand for CRAC cooling. Lack of knowledge about the efficiency of the cooling system's behavior and efficiency has typically resulted in overcooling, primarily to prevent equipment failure, which leads to wasted energy and poor power usage effectiveness.

Vigilent Corp., formerly Federspiel Controls Inc., developed a data center energy management system that monitors and controls data center system cooling power consumption and cooling efficiency in real time. Vigilent, with assistance from AMO (as part of the American Recovery and Reinvestment Act), recently demonstrated the effectiveness of intelligent energy management in eight State of California data centers. The system uses a network of wireless sensors, hardware, and software to automatically and intelligently control the data centers' cooling operation provided by air handling units (AHUs) and CRAC units.

The Vigilent system provides a visualization of the facility layout and graphical displays showing real-time thermal conditions, and the actual effect of each HVAC/AHU's operation on temperatures throughout the facility. The system analyzes and optimizes cooling by enabling dynamic adaptive cooling control and load balancing. Vigilent has successfully demonstrated its data center cooling management technology solutions at multiple high-profile sites, including Verizon as well as the State of California sites. The case study at the California sites resulted in annual energy savings of over 2.3 million kWh. Other Vigilent customers report even larger savings at their installations.
