Building services engineering

Buildings in Switzerland are responsible for more than 40% of the primary energy consumption and the CO2-emissions. Therefore, buildings offer large potentials for primary energy savings and CO2 emission reduction. 

The focus of the building system technology group is:

  • Innovative building technology with heat pumps
  • Building technology for efficient buildings and Net Zero Energy Buildings
  • Building controls
  • Passive cooling methods (Free-Cooling)
  • Energy and water use in Buildings

We support industry partners with the following competences:

  • Coupled dynamic building and system simulation
  • Simulation based component development and system integration
  • Model based development of control strategies
  • Scientific accompaniment of field monitorings
