What is TRNSYS?
TRNSYS (pronounced: ‘tran-sis’) is a software package that has been commercially available since 1975. The software package consisits of a graphical front-end (TRNSYS Simulation Studio) to intuitively create a simulation, an interface for the detailed TRNSYS multi-zone building (TRNBuild/Type56), a Google SketchUp plugin for creating the multi-zone building envelope (TRNSYS3D), and a tool for manually editing the TRNSYS input files and creating stand-alone TRNSYS-based applications (TRNEdit/TRNSED). TRNSYS takes a modular, “black box” component approach to developing and solving simulations: the outputs of one component are sent to the inputs of another component (transient successive subsitution). TRNSYS has been used extensively but is definitely not limited to simulate solar processes and other renewable energy, high performance buildings, and electric power generation.
