The multi-zone building model enables the coupling of thermal simulation with daylight simulation. This allows the control of the artificial light to be based on the daylight available locally in the room. The integral implementation considerably reduces the input effort.

Complex glazing systems (CFS) place considerably high demands on modelling. Especially the bi-directional scattering of radiation, as it occurs for example in lamella systems or honeycomb structures, and interaction with the individual layers can now be modelled in great detail.

The newly integrated model based on ASHRAE 55-2013 Appendix G, allows an adaptive comfort assessment based on the Standard Effective Temperature (SET), taking increased air velocity into account.

With TypeStudio, a Fortran-compiler with GUI specially adapted for TRNSYS, both standard and custom components can easily and quickly be adapted by the user and integrated into TRNSYS.

The simulation engine of TRNSYS is now available as 64bit version. In the course of this, numerous calculation routines have been improved, an interface to Phyton has been created and simplified components for beginners have been added.

Rhinoceros (3D-modeler) in combination with the Grasshopper plugin have numerous interfaces and possibilities to create and vary parameterized 3D models and to process information. For easy use of these possibilities for building simulation with TRNSYS, the free plugin TRNLizard for Grasshopper was developed.
