Best focus on research questions through easy handling and open source models.

Since many years TOP-Energy® has been successfully used in various colleges, universities and institutions of applied research. As simulation software for energy systems, it combines thermodynamic depth with a fast learning curve. Open model descriptions enable the verification and manipulation of the equation systems, as well as the creation of your own components for highly innovative plants or controls. Scientists can therefore concentrate fully on their research questions from the very beginning.

Due its uncomplicated use and the many pre-configured components, TOP-Energy® is also ideally suited for use in teaching. Final papers and exercises on supply concepts for municipalities and industry, energy efficiency or power plant planning therefore fit more easily into the often limited time frame.

 Benefits at a glance:

  • Comprehensive thermodynamic calculations for electricity, heat, cold, steam and compressed airComprehensive thermodynamic calculations for electricity, heat, cold, steam and compressed air
  • CHP, CCHP combined cooling heat & power (trigeneration), storage, renewable and conventional energy generation in one model
  • An integrated economic, ecological and energetic comparison of different supply variants
  • Fast familarisation and intuitive usage
  • Full insight into the equations systems and calculation parameters
  • Possibility for independent programming of components and system controls

Grubenwasser Ruhr

Development of innovative and efficient heat utilization concepts considering mining infrastructure in the Ruhr area

„I was impressed by the speed with which I can model complex energy systems compared to other simulation tools. The software shows its strengths particularly in the processing of time series and an additional economic comparison of variants. I also find the appealing Sankey-like representation of the energy supply structure extremely practical.“
M.Eng. Alexander Emde
M.Eng. Alexander Emde Research Associate, University of Stuttgart/Fraunhofer IPA

Test TOP-Energy® free of charge & without obligation for 30 days

Use in teaching

The fast familiarization makes TOP-Energy® an ideal tool to introduce students to the advantages of simulation tools in practice. Renowned universities and various colleges use our affordable classroom licenses for their computer labs.

„The Chair of Technical Thermodynamics at RWTH Aachen University has been running the "Alternative Energy Technology" ring laboratory since 2011. More than 100 students use TOP-Energy every year to analyze the use of renewable energy sources. The students compare variants for covering heat and electricity requirements with regard to economic and ecological criteria. The students rate the event as very interesting. The students awarded an average grade of 1.75 for the event.“
