It all started at the University of Stuttgart, because we were familiarized with the TRNSYS Software at the Institute for Thermodynamics and Thermal Engineering (ITW). Our company name is also based on TRNSYS and Solar.

Transsolar KlimaEngineering has been designing innovative energy and building concepts since 1992. Over the years, the concepts have changed considerably; they must meet current standards, integrate developments in building automation and use innovations in building services engineering. We call our work KlimaEngineering. Its success is based on software tools and their availability to model innovative energy and climate concepts. Many of these tools, which engineers use to validate their creative solutions, have also changed over the years. Some have been added, others replaced – but TRNSYS remains our primary simulation tool.

This is partly due to the fact that we have been working in-house to continuously develop the multi-zone building model of TRNSYS. Such a model contains the most important building physics principles and thus forms the core of the respective climate concept. The daily work of the climate engineers with its growing requirements drives the continuous further development of TRNSYS.

We do not keep the developments and improvements in-house, but pass them on by transferring them to the TRNSYS software package and making them available to users in updates or new versions. We are a member of the international TRNSYS developers‘ team, whose continuous exchange of ideas is crucial for the performance of the software.
