New German study on how to reduce energy costs of computer centres by up to 75 %

Share this Post:
Private and public organisations can reduce the energy costs of computer centres by up to 75 % by targeted technical optimisations. The necessary investments will be repaid generally after 2-3 years. The initiative "EnergieEffizienz" of the German energy agency "dena" presents the 4 most important fields of action for increasing the efficiency of computer centres: optimised use of server capacity, thermal improvement of the centre (splitting into warm and cold air spaces), use of modern and energy efficient IT hardware and optimised use of programs and data.
Dena indicates the possible reduction of energy use as follows:
- optimised use of server capacity: 35 % and more
- thermal improvement of the centre (splitting into warm and cold air spaces): 20 %
- use of modern and energy efficient IT hardware: up to 15 %
- optimised use of programs and data can lead to a possible reduction of the number of servers.
On the website www.energieeffizienz-im-service.de a guidebook and an information graphic for download is offered.
