e-shelter planning and design implements highest standards in energy
efficiency and latest developments in technical progress
Energy efficiency and sustainability
Research & Development
In 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 excellence
e-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).

Security
Structural, technical and organizational separation of the security zones
Security Systems
 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/

Power and Cooling Systems
The redundant power supply guarantees maximum availability
Power supply
 Power is distributed on an A & B feed up to the rack
 The critical components of the power supply are designed in an 2N+1 configuration
 State-of-the-art static UPS systems with a high degree of scalability and reliability incl. isolating transformers
 On-site back-up power (diesel generators) in an N+2 configuration
 72h diesel-fuel storage on site.
