Re: [EnergyPlus_Support] Building geometry modification

[Rob Hitchcock <RJHitchcock@xxxxxxx>]

Rajendra,

You could try the IFCtoIDF translator that converts the building 
geometry in CAD drawings saved in IFC format into IDF format (see 
http://www.eere.energy.gov/buildings/energyplus/ifc.html).  This is 
still a beta product, but it would allow you to draw your building and 
make changes in CAD and then more easily transfer these changes to 
EnergyPlus.  You would need to do some manual editing of the IDF to 
change Construction types of the envelope elements.  The IFCtoIDF 
utility is included as part of the EnergyPlus download and can be 
installed by checking the IFCtoIDF checkbox during installation.  Note 
that you should then download the update of this utility from the 
EnergyPlus Support website at the URL below.
