Why a Sustainable Data Center is More Than a Promise

Digital transformation is energy-intensive. As demand for computing power continues to grow, so does awareness of its impact on the climate. A modern data center must therefore deliver not only performance and reliability, but also responsible, sustainable operations.

The Data Center Stollen Lucerne was designed with a clear goal: maximum sustainability across the entire infrastructure. Every aspect of its construction was guided by environmental responsibility. Through intelligent infrastructure design, the use of renewable energy, and innovative technologies, we minimize our ecological footprint – without compromising security or availability.

How Sustainability is integrated at the Data Center Stollen Lucerne

Sustainability is a core operational principle, not an afterthought. At the Data Center Stollen Lucerne, we back this commitment with measurable actions, including:

  1. Operation with renewable energy

    Our servers run exclusively on renewable electricity from natural resources, primarily from hydropower.

  2. Ecological lake water cooling

    The cooling of our ecological data center is not done by conventional chillers with compressors but by cold water from the nearby lake. Therefore, no electricity is needed for the actual cooling generation.

  3. Waste heat utilization for the surroundings

    The waste heat from the data center is fed into the local heating network and used to heat neighboring buildings. This creates a meaningful energy cycle.

  4. Sustainable construction

    Instead of new construction, we focus on repurposing: The former civil defense bunker is efficiently reused. This reduces gray energy and saves resources. Thanks to the underground construction of the bunker, valuable space on the surface remains free.

  5. Technology for energy efficiency

    State-of-the-art DCIM systems and flywheel UPSs guarantee the highest efficiency in power supply, monitoring, and control of the systems.

  6. Responsibility in the industry

    As a member of the Climate Neutral Data Centre Pact, we are committed to climate-neutral operation.

That's why a green data center is indispensable today

An extremely sustainable data center is more than a bonus today. It is an important part of a responsible corporate strategy. Those who outsource IT performance can actively participate in deciding how environmentally friendly it is provided.

The Stollen Luzern Data Center combines powerful infrastructure with consistently sustainable operations. This creates the conditions for IT that not only works but also protects the environment. Because sustainability is no longer an addition; it is an expectation. We provide the appropriate infrastructure for this.
