The origins of TOP-Energy® can be found in doctoral theses and other research projects carried out at RWTH Aachen University around the turn of the millennium.
The simulation software is now located in the GFaI’s Graphic Engineering Systems (Graphing) research area. TOP-Energy® has been continuously developed in an independent working group since 2003. The team includes energy- and process engineers, modeling experts, and software developers. The main focus of development is to expand the range of functions and to make TOP-Energy® increasingly easy and intuitive to use.
