The Archsim Energy Modeling component for Grasshopper allows you to quickly create multi-zone energy models and simulations for building design. The tool comes with an abstract thermal model class library and various functions such as “early design auto-zoning”, “automated intersections” etc. that assist you with model creation, simulation and result visualization. Currently, supported simulation engines are Energy Plus 8.0 and ( TRNSYS 17). However, the open library allows you to extend the output functionality for any other simulation package.
