Besides EnergyPlus version 8-1-0 support the same workflow can also produce TRNSYS B17 files.

Archsim exports native IDF files that are fully customizable. Archsim is a young tool under heavy development and new features are added frequently. Simulation inputs such as model geometry, materiality, constructions and zone usage profiles are fully parametric and can be coupled with optimization algorithms within Grasshopper. It is typically used for rapid early design exploration where building shape, window to wall ratios, facade and glazing systems and passive approaches such as shading and natural ventilation potential are tested for their impact on the building environmental performance and comfort. Archsim supports advanced daylighting and shading controls, ventilation modules such as wind and stack natural ventilation, airflow-networks, simple HVAC, photovoltaics and phase changing materials. Archsim allows you to effortlessly create complex multi-zone energy models, simulate them and visualize results without ever switching between tools. Hi all - Archsim Energy Modeling is a plugin that, for the first time, brings fully featured EnergyPlus simulations to Rhino/Grasshopper and thus links the EnergyPlus simulation engine with a powerful parametric design and CAD modeling environment.
