Withemergence of Internet the number of data centersgrows rapidly causing dramatic increment of energy consumption in this sector. Modern data centers not only consume the comparable amount of energy to other traditional industries such as steel, but also they are expected to overtake them in the near future. Moderndata centers require cutting edge industrial automation, information, control and power system technologies to efficiently manage their power supply, cooling, security and other facilities. The efficiency of datacentres has many contributors, such as heating, cooling, ventilation, data processing, and air-conditioning, which can be improved via computing load balancing, energy consumption and electrical power management. This special session is organized to address the current challenges and problems of this new and fast growing industry from efficiency perspective. We invite researchers and technologists from a broad range of expertise and specializations to discuss and share their ideas, found problems, challenges and solutions in this multidisciplinary arena of research and development.
