Energy-efficient IT

The branch office of the Liechtensteinische Landesbank in Eschen (FL) has set standards for the Rhine Valley region since December 2012. The LBB data processing centre, which is an extremely safe data centre, was awarded Tier III Certification of Design by the Uptime Institute. This means that highly sensitive business data are perfectly protected and can be accessed at all times. Our data processing centre not only has one of the highest safety standards of eastern Switzerland, it also reflects a clear commitment to «Green IT». All building elements – from the construction, to the insulation and the architectural design of the building – were carefully matched to each other in order to increase energy efficiency.

Sustainable construction is based on the functional interaction between ecology and technology and is becoming the standard. In compliance with this standard, the construction of the new LLB data processing centre permits the specific use of only single modules. The server and the cooling elements are positioned in such a way that only the computer is cooled and not the entire room. The power consumption of the cooling devices plays an essential part in terms of power usage effectiveness (PUE). We aim to achieve a value of below 1.5 PUE, which would be half the original energy usage. In 2013, we were already able to achieve a PUE of 1.54.

The interplay of ecology and technology in construction is a main concern throughout the LLB Group. The Bank Linth branch offices in Pfäffikon (SZ), Kaltbrunn (SG) and Schmerikon (SG) were built in accordance with «Minergie-P®» standards (not certified); and the construction of the LLB branch office in Eschen, in particular, complies with «Minergie-P®» standards. LLB has received provisional certification, which is valid until 2015. State-of-the-art lighting technology ensures power savings of approximately 18'000 kilowatt-hours. Only half as much energy is consumed for lighting as prescribed by law. At the same time, a properly insulated building envelope and the use of waste heat from the adjoining Data Center to heat the branch office result in a saving of 9'000 m3 of natural gas. Since mid-2013 we have been able to substantially lower power consumption and, consequently, clearly reduce CO2 emissions too. We expect annual savings in energy costs at our Eschen branch office of approximately CHF 13'000. However, we will not be able to make a comprehensive assessment of power efficiency on the basis of real power consumption until 2014.
