- What is TRNSYS?
- What is included in the TRNSYS software package?
TRNSYS (pronounced: 'tran-sis') is a software package for energy simulation of solar processes, building analysis, thermal energy, and more. The software has been commercially available for over 35 years.
The TRNSYS software package consists of the Simulation Studio, the graphical front-end for TRNSYS, TRNBuild, the interface for the TRNSYS building model, TRNEdit, and TRNSYS3D. More information about these is located at the Features section of the website.
General TESS Libraries Questions
- What are TESS Libraries?
- Do I need all of the TESS Libraries?
The TESS Libraries are add-on component libraries for TRNSYS. There are over 250 TESS Libraries Components in 14 different Libraries.
It depends on the types of projects to be conducted with TRNSYS. It is a much greater value to purchase all 14 of the TESS Libraries. The descriptions of the TESS Libraries and the components may be found at the TESS Libraries section of the website.

No, you do not need a fortran compiler to use TRNSYS. For the advanced users who wish to create their own TRNSYS components to use in their simulation, a fortran compiler is required.
As of right now, only the Windows operating system (XP/Vista/Windows 7) can be used to run TRNSYS.
