A functioning and secure IT system is one of the university’s most important infrastructural requirements. The ever-increasing importance of IT brings with it, however, considerable energy demands for the operation of the hardware and cooling systems.
The project Green IT was implemented in 2009, in order to unlock the energy efficiency potential across the university’s entire IT system. Within the framework of a comprehensive inventory of the entire IT system, it was ascertained that the IT equipment was responsible for at least 20 percent of Freie Universität's total energy consumption. Additional factors include the considerable energy requirements of the network centre, voice over IP (VoIP), UPS devices and notebooks, which were not detailed in the framework of the inventory. In total, the estimated energy consumption for IT equipment has been reduced by more than 10 million kilowatt-hours annually, a cost of around 1.8 million.
In 2010, an internal Green IT action programme was developed, based on the IT inventory, involving optimisation measures for all IT-related operational fields. The most important measures include structural improvements in terms of procurement, simplified centralization and virtualization of the server, and the large-scale implementation of tailored PC and server operations. Furthermore, greater attention will be paid in the future to the transparent and energy efficient regulation of server operation, but also to training and raising employee awareness. The broad spectrum of measures, which should be systematically implemented within the next few years, can be viewed in the attached overview.
