I can add to the Importing list CYPETHERM EPlus, an energy simulation software which is a BIM user interface of EnergyPlus v8.9. CYPETHERM EPlus can import ifc and gbXML files containing the 3D model of the building as well as other information such as the HVAC systems or the lights power. The building energy model can be fully defined in the program, which also runs the simulation in EnergyPlus v8.9 and shows the results. Finally, it can export an ifc file containing the simulation results.
In the Exporting list for 3D modeling software, I can add IFC Builder. This is a free software that produces an ifc file with the 3D geometry of the building.
Regarding the workflow, the CYPETHERM software package is able to produce ifc files that cover the complete the BIM workflow for HVAC systems design and energy simulation. Once you have an ifc file with the 3D geometry, this can be imported into CYPETHERM LOADS for thermal load calculation and CYPETHERM HVAC for HVAC systems design and sizing. These programs are also able to produce an ifc file with their results, which enrich the building model. As I said above, these results can be read by CYPETHERM EPlus, which runs the simulation of the building in EnergyPlus v8.9 and creates an ifc file with these results. Finally, this file can be imported into CYPETHERM Improvements to compare different hypotheses for the same building.

This video is a demonstration of the BIM workflow with this software.
