Data Center Engineering

Approach

How can we meet the growing demand for data without harming the environment?

Digitalization needs energy efficiency

Data centers are the backbone of the digital world, but they consume enormous amounts of energy. With smart cooling systems, precise control and intelligent architecture, we drastically reduce the energy requirement per computing unit. We rely on pioneering technologies such as liquid-to-liquid cooling concepts and thermal transformer systems. With intelligent data center engineering, we create the basis for scalable, economically and ecologically sustainable digital infrastructures.

Scalable performance, made clear

An autonomous vehicle generates up to 1.2 terabytes of data every day. A single rack in a modern data center can process the data volume of over 8,000 vehicles per day. We develop infrastructures that can reliably handle such dimensions - including for high-density applications, AI workloads and future computing architectures up to quantum readiness. Powerful, secure and future-proof.

Investing where it counts

When building a data center, around 80 percent of the investment costs are accounted for by the technical building equipment and only 20 percent by the building itself. Our planning starts where it has the greatest impact: with thermal efficiency, system resilience and the future viability of the infrastructure. This is precisely where our expertise in advanced data center engineering comes into play.

For us engineers, the data center industry continues to be a dynamic environment full of growth, innovation and exciting career opportunities. The opportunities for innovative designs and energy efficiency create an inspiring environment that attracts young talent.

Power Usage Effectiveness (PUE)

The PUE value measures the energy efficiency of a data center. An ideal PUE of 1.0 corresponds to maximum efficiency. The industry-wide average has been around 1.58 since 2020, although innovative IT and building concepts have helped to reduce the average PUE over time

From Insight to Practice: living interdisciplinarity

Our Chairman of the Board of Directors, Prof. Adrian Altenburger, has been involved in the planning of data centers for over 30 years - initially as an engineer, and now also as Head of Institute at the Lucerne University of Applied Sciences and Arts (HSLU). What he brings to our projects is interdisciplinarity across all trades: like here on the construction site of a new data center campus in the Zurich area, together with our HVAC and electrical team. Complex technology, coordinated from a single source.

Balance between power and surface area

Access to the power grid is the undisputed bottleneck for the data center industry's growth plans.

Data Center Insights: Digital infrastructure in dialog

With "Data Center Insights", we have been bringing the most exciting topics in the data center industry into conversation since 2024 and connecting people who are driving innovation. Speakers from Amazon Web Services, HSLU, BCS Consultancy and IBM Research to Green have already reported on challenges, opportunities and future-proof solutions.

The next round of the event will take place in fall 2026.

Thermal Transformer - new efficiency class for adsorption cooling

Adsorption heat pumps and chillers have long been considered expensive and bulky - limited by inefficient materials and heat exchangers. With Thermal Transformers, we increase performance, flexibility and efficiency through innovative high-performance materials and optimized geometries. We are developing new application scenarios such as data center cooling, in which GPU waste heat (approx. 45 °C) is converted into usable cooling and the energy requirement is significantly reduced. We also define application limits and integrate the technology optimally into existing data center infrastructures.

Data center feasibility studies

We carry out ongoing feasibility studies for data centers and assess their feasibility on land reserves and in site developments. The focus is on key investor issues along the entire development cycle:

- Powered Land: Availability and scaling of the electrical supply

- Ready-to-build: Basis for planning permission (including utilization, building heights, special use regulations), planning and implementation time

- Carbon footprint reduction: chiller design, waste heat utilization, sector coupling, seasonal storage

Services

Our teams develop scalable data center infrastructures - secure, efficient and future-proof. Our approach to data center engineering ensures that everything works together.

As general planners, we bear overall responsibility for complex construction projects - from technical planning to execution. We coordinate all trades and ensure quality, deadlines and costs.
