Question-and-Answer Resource for the Building Energy Modeling Community
 | 1 | initial version |
One possibility for the cause of this error is that the EnergyPlus version used in your Design Builder install is a different than the EnergyPlus OpenStudio is using. EnergyPlus has different versions. You can translate an .idf to a newer version with the Transition Version option in the file menu of EP-Launch. You can check the version of an .idf file by opening the .idf in a text editor and looking at the Version identifier tag (should be the first object).
Another possibility is that you have objects in your EnergyPlus file that are not yet available in OpenStudio. If so, the error message may tell you what type of object it is having issues with.
