Supplied source code and documentation provide an easy method for users to modify or add components not in the standard library extensive documentation on component routines, including explanation, background, typical uses and governing equations supplied time step, starting and stopping times allowing choice of modeling periods. Main applications include: solar systems (solar thermal and photovoltaic systems), low energy buildings and HVAC systems, renewable energy systems, cogeneration, fuel cells.ĭue to its modular approach, TRNSYS is extremely flexible for modeling a variety of energy systems in differing levels of complexity. TRNSYS has become reference software for researchers and engineers around the world. TRNSYS is well suited to detailed analyses of any system whose behaviour is dependent on the passage of time. One of its original applications was to perform dynamic simulation of the behaviour of a solar hot water system for a typical meteorological year so that the long-term cost savings of such a system could be ascertained.

TRNSYS is a commercial software package developed at the University of Wisconsin.

TRNSYS is a simulation program primarily used in the fields of renewable energy engineering and building simulation for passive as well as active solar design.
