TRNSYS software : capabilities & application in buildings simulation


– To learn about TRNSYS software capabilities.
– To practice a simple building simulation exercise.


Prof. Brahim Benhamou, Cadi Ayyad University, Marrakech, Morocco


– Global overview of TRNSYS software.
– Global overview of TRNSYS software capabilities.
– Hand-on quick exercise: how to build a mono-zone building simulation.


You should bring your laptop with you if you want to benefit from the hand-on quick exercise.
TRNSYS is a commercial software. If you do not have a license, a demo version should be installed prior to the tutorial attendance. It may be downloaded for this link:

TRNSYS is one of the powerful fully flexible tools for energy and dynamic systems simulation.
TRNSYS (pronounced ‘tran-sis’) is an extremely flexible graphically based software environment used to simulate the behavior of transient systems. While the vast majority of simulations are focused on assessing the performance of thermal and electrical energy systems, TRNSYS can equally well be used to model other dynamic systems such as traffic flow, or biological processes.
TRNSYS is made up of two parts. The first is an engine (called the kernel) that reads and processes the input file, iteratively solves the system, determines convergence, and plots system variables. The kernel also provides utilities that (among other things) determine thermophysical properties, invert matrices, perform linear regressions, and interpolate external data files. The second part of TRNSYS is an extensive library of components, each of which models the performance of one part of the system. The standard library includes approximately 150 models ranging from pumps to multi-zone buildings, wind turbines to electrolyzers, weather data processors to economics routines, and basic HVAC equipment to cutting edge emerging technologies. Models are constructed in such a way that users can modify existing components or write their own, extending the capabilities of the environment.
After 42 years of commercial availability, TRNSYS continues to be a flexible, component-based software package that accommodates the ever-changing needs of both researchers and practitioners in the energy simulation community.
