Sustainability, environmental protection and climate neutrality are terms that have become indispensable in business, politics and society today. Siemens had already focused on these aspects years earlier, however, and paid particular attention to environmental protection and sustainability when it built the EAGLE Data Center in Munich in 2013. The Data Center has set new standards in Green IT and received the LEED Gold certification for its commitment.
Globalization continues to advance and with it the use of information and communication technology. Besides many positive effects, however, this also leads to an increasing consumption of resources and electricity. It is hard to believe that the annual CO2 emissions caused by communication and information technology even exceed the emissions of aviation as a whole.
However, this is different in the EAGLE Data Center. Here, numerous environmental protection measures were already taken during the construction period in 2013, when sustainability and climate neutrality hardly played a role in most economic, social and political areas, in order to promote greener and more sustainable information technology.
Green IT in the EAGLE Data Center
The EAGLE Data Center in Munich attaches great importance not only to maximum security but also to sustainability and is thus a pioneer in the field of resource-saving IT. Many advanced technologies are used here to reduce environmentally harmful CO2 emissions, only some of which are presented below.
The EAGLE DC uses e.g. state-of-the-art hybrid coolers which provide various modes. Depending on the external conditions, the best and most efficient operating mode is automatically selected. The so-called adiabatic cooling, i.e. evaporation cooling, is also used here, which delays the operation of mechanical cooling by several hours per year. This makes it possible to supply the Data Center with free cooling up to 80 % of the time without having to resort to a refrigeration machine.
In addition, chillers with frictionless and oil-free turbo compressors are used, which enables optimum efficiency of the chillers due to low condenser temperatures. As no oil is used, it does not have to be replaced, which contributes significantly to the protection of the environment. The design of the computer rooms also reduces the amount of energy required for cooling, as this ensures an optimum air flow within the rooms and thus makes optimum use of the cooling system.
With the help of an efficient heat pump, the waste heat of the IT devices in the EAGLE Data Center supports the building heating. Further, this thermal energy is also used for building ventilation. Heat recovery is realized by a so-called rotary heat exchanger, which avoids cost-intensive electrical heating.
The Data Center purchases exclusively green electricity from the public utility Stadtwerke München, so that sustainability and environmental friendliness can also be guaranteed when operating the numerous servers and electronic devices.
The EAGLE Data Center was awarded the LEED Gold certificate for its environmental protection measures, which certifies resource-saving and sustainable construction. Some points from this are the use of rainwater in sanitary facilities, a favorable transport connection, which allows an intensive use of local public transport, green roofs to support the climatic conditions in the building, the use of local and recyclable materials as well as the avoidance of environmentally harmful materials and the use of heat recovery in the air conditioning system.
The EAGLE Data Center has since then been a pioneer when it comes to Green IT and the use of the latest technologies to protect the environment and makes a significant contribution to the goal set forth by Siemens AG to become climate-neutral by 2030.
