TRNLizard

Free plug-in for Grasshopper for parametric 3D building simulation developed by TRANSSOLAR. TRNLizard is a free plug in to the Rhinoceros 5 software and Grasshopper. It enables thermal and daylight building simulation with TRNSYS 18 using a variety of artificial lighting, ventilation, heating and cooling concepts based on detailed 3D geometry.

The parametric architecture and open source Grasshopper components enable TRNSYS 18 users to conduct detailed design studies during the planning phase and respectively individualize the model. Predefined templates and outputs allow quick start simulations and a fast evaluation of simulation results.

The tool has a modular structure and gives great flexibility. The components are and will be adapted to the development of Trnsys and have a variety of new features. Models are fully defined in Grasshopper and then written as complete TRNSYS-models in the project directory. TRNLizard connects the power of parametric modeling in Grasshopper and the latest building simulation features of Trnsys!
