A future ready transformation for Reutte Hospital

A new approach to energy, infrastructure and partnership is transforming Bezirkskrankenhaus Reutte into a future-ready, climate-conscious hospital campus.

A growing vision for a sustainable hospital campus

Bezirkskrankenhaus Reutte has pursued energy improvements for several years in collaboration with Siemens since 2019. A planned upgrade for a newly built care home revealed the potential to reimagine the energy strategy on a campus‑wide level.

The discussions around the next project phase quickly showed that a single‑building upgrade would not maximize the campus’s long‑term potential. With two care homes, a nursing school, student housing, and staff accommodations, Reutte required an energy concept capable of serving a diverse and interconnected environment.

Expanding the scope enabled the hospital to accelerate its sustainability ambitions and operate more efficiently. Implementing a climate‑friendly energy system across an active healthcare campus demanded careful coordination so that buildings, technical systems, and daily operations could be integrated smoothly into the new solution.

Seamless integration

The new energy concept connects smoothly to the existing heating network, enabling both older buildings and the new care home to be included without major structural adjustments or operational interruptions.

Sustainable heating

A heating solution that reduces emissions by 1,580 tons of CO₂ per year and supports the hospital’s long-term sustainability goals.

Transparent campus operation

Transparent, integrated operation enabled by Desigo PX and Desigo CC, providing clear system insight and stable, efficient performance across the entire campus.

How Reutte’s energy transformation took shape

To bring this expanded vision to life, Siemens developed a unified energy concept for the entire hospital campus. At the center of the solution is a new heat generation plant that introduces modern, renewable technology into a complex healthcare environment.

Three high‑temperature heat pumps form the core of the system, providing a combined heating capacity of 1,200 kilowatts. They operate using a groundwater extraction and reinjection system that not only supplies heat but also replaces the hospital’s previous mechanical cooling with a more efficient groundwater‑based method. The system integrates seamlessly into the existing heating network and is supported by dedicated heat storage to balance demand throughout the day.

Safety and reliability remain essential. The site includes 45,000 liters of oil storage as an emergency reserve, plus a gas detection system to ensure safe operation. All disciplines are digitally connected through Desigo PX for control and Desigo CC for central monitoring, giving the hospital clear visibility into campus-wide performance.

This integrated setup brings together HVAC, groundwater systems, ventilation, electrical installations, lighting, and digital building management into one coordinated solution that supports the hospital’s long-term sustainability goals.

With our climate‑neutral heat generation center, we are once again demonstrating our expertise in digitalization and sustainability.

Seeing the bigger picture in campus energy

Reutte’s transformation shows what becomes possible when a single modernization idea grows into a holistic campus strategy. Instead of upgrading one building at a time, the project connects heating, cooling, ventilation, electrical systems, and digital management into one coordinated energy concept.

This approach allows even the hospital’s older buildings, including structures dating back to the 1960s, to benefit from renewable heat, efficient groundwater cooling, and transparent system monitoring — all without major disruption to daily hospital activity.
