e-shelter planning and design implements highest standards in energy efficiency and latest developments in technical progress Energy efficiency and sustainability
Research & DevelopmentIn order to develop best-practice approaches for energy efficient operation of data centers e-shelter is actively engaged in different workshops and organisations e.g. “the green grid“ and “Uptime Institute.”
e-shelter works with large suppliers of cooling technology to explore and test new cooling techniques, and has developed a sophisticated measuring system to continuously monitor energy utilization (e.g. cooling requirements in different zones).
Operational excellencee-shelter designs and operates its data centers to be highly efficient and applies state-of-the-art technology to achieve an optimal utilization of energy. Hereby e-shelter is able to achieve highly competitive power utilization efficiency factors for its data centers (PUE factor).

The security concept includes having all safety-sensitive areas situated in the core of the building to the extent where this is feasible so that the security zones beyond the core serve as buffers.
All security zones are structurally, technically and organizationally separated from one another
All security zones are monitored by way of synchronized technical safety measures
This way it is ensured that the cumulative safety function for creating the necessary penetration resistance/ resistant time value
