Institute of Technology, Resource and Energy-efficient Engineering (TREE)


At the Institute for Technology, Resource and Energy-efficient Engineering (TREE) at Bonn-Rhein-Sieg University of Applied Sciences, we conduct interdisciplinary research into technical and scientific topics as a team of scientists. We bring expertise in various scientific disciplines such as chemistry, materials science, electrical engineering, computer science, mechanical engineering, journalism and communication science to our research. State-of-the-art laboratories and equipment are available for this purpose.

Digital Twin-4-Multiphysics Lab

The "Digital Twin-4-Multiphysics Lab" (DT4MP) combines engineering sciences and computer science in a unique network. The aim is to develop new machine learning methods and apply them to simulations and experimental technical systems.

Dynamic Lab Thumbnail


Vibration analyses can be carried out in the dynamics laboratory. An electrodynamic shaker payload is available for this purpose. Vibration analysis is carried out classically via acceleration measurement and modal analysis or via an optical 3D measurement.

Energy Meteorology Lab Thumbnail

Energy Meteorology Lab

The laboratory is used to improve the prediction of radiation and thus improve the control of PV storage systems. It investigates grid-integrated PV hybrid systems with batteries and PV power-to-gas-to-power systems (photovoltaic systems) that are connected to hydrogen-metal hydride storage systems.

Hydrogen Lab Thumbnail


The Hydrogen Lab offers a complete illustration of H2 cycles: From energy generation using solar technology and its conversion into H2, taking into account system technology, through storage and grid integration to electricity generation from stored H2.

LCA Lab Tumbnail

Laboratory for life cycle assessment

In life cycle assessment (LCA), the environmental impact of a product, service, process or operation is recorded and evaluated.


Labs for Materials and Processes Thumbnail

Labs for Materials and Processes

The materials and processes laboratories specialize in materials analysis and the development of sustainable materials. They offer advice and support in the selection of optimal materials, optimization of manufacturing and assembly processes and quality defects and complaints.


Mobility Lab Thumbnail

Mobility Lab

The laboratory conducts research into innovative vehicle and drive concepts, battery energy storage solutions, bidirectional charging, control processes for system services, aerodynamics, mobility alternatives, route optimization, materials and sustainability analyses.

Simulation Lab Thumbnail

Simulation Lab

New multiscale simulation methods or optimization algorithms that deal with different types of minimization problems make it possible to select the optimal design solution from a multispace simulation result and identify optimal solutions.
