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).


Data Center Zurich 1 (ZRH1)

e-shelter‘s first datacenter in Switzerland is located in the north of Zurich,approx. 8 km from the city centerLocation


The largest purpose-built data center in SwitzerlandBuilding

The freestanding building is designed and built solely for the purpose of housing IT infrastructure. All external and internal building features are constructed with high quality materials and meet or exceed industry standards.

The first stage of construction provides 7’000 sqm of net data center space and 1’000 sqm of office space

The facility meets the LEED (Leadership in Energy and Environmental Design) Platinum pre-certification

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

Power and Cooling Systems

The redundant power supply guarantees maximum availabilityPower 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.
