Well positioned for security

The first e-shelter data center in Switzerland, which opened in June 2011, is located in Rümlang near Zurich. The building, consisting of two parts, has about 7,000 sqm of high-availability data center space in the first building. In the new building, which has been planned and equipped solely for use as a data center, state-of-the-art technology is being used to increase energy efficiency, in particular cooling technology. For example, CO high-temperature heating pumps are being used to heat the large office and warehouse spaces outside the data center and collected rainwater will be used to cleaning the ventilation systems.

The building also has received the LEED Platinum Pre-Certification from the US Green Building Council.
