From challenge to circular transition

CHALLENGE

  • Heating, Ventilation and Air Conditioning (HVAC) systems account for ~50–70% of total building energy consumption
  • Retrofits can deliver up to 40% efficiency gains, improved air quality & less maintenance
  • End-of-use systems are typically replaced without structured take-back, resulting in lost reuse potential, materials and avoidable costs

PROJECT ACTIVITIES 

  • Establish circular take-back loops for HVAC products and components - starting with refurbishment of ebm-papst fans via Güntner
  • Implement end-to-end workflows to identify and locate units, remove/disassemble, take back, test and grade, refurbish or retrofit
  • Validate feasibility, processes and business models (e.g., Cooling-aaS as future scenario)

OUTCOME

  • Proof of concept delivered with first fan batches taken back, refurbished and resold
  • Transition from pilot to replicable solution initiated, with extension to additional product types and integration into standard operations
  • Foundations laid for further circularity use cases with additional partners (incl. industrial retrofit, data centers, retail applications)
     

CIRCULAR TRANSITION

  • Building a lighthouse example as first movers within the industry
  • Potential extension to broader buildings-related ecosystem and group of players beyond HVAC in 2026 (incl. data centers)

The circular economy represents one of the most important transformation opportunities ahead. Unlocking its full potential - across sustainability, supply security, and economic growth - demands clear vision and decisive partnerships. In close collaboration with Güntner, we have chosen to move from intent to execution, taking the first strategic steps toward shaping this future together.
