The IDF2PH toolkit is made of three main pieces:
New PHPP Tools for Rhino
New PHPP Tools for Honeybee
A New IDF->PHPP Exporter
The IDF2PH tools allow you to construct, refine and control the entire PHPP static energy model from with Rhino's grasshopper environment while simultaneously creating a parallel model within Honeybee and EnergyPlus for dynamic model assessment. These tools allow for a wide variety of uses and levels of detail, from simple geometry export from the IDF up to complete PHPP control and multi-zone modeling. The tools can also be used for simple IDF-->PHPP export and conversion even without using any of the Honeybee or Rhino side components.
