OpenStudio is unable to load EnergyPlus files

I download the model of supermarket from DOE's Commercial Reference Building Models, and transfer it into the version-8.6 EnergyPlus model. However, when I import the IDF file into OpenStudio 1.14.0 and 2.0, it says that some portions of the idf file were not imported (Only geometry, constructions, loads, thermal zones, and schedules are supported by the OpenStudio IDF import feature).

Does it mean that OpenStudio is unable to load EnergyPlus files created by DOE? And are there some solutions to solve this problem?

This isn't a reference building issue specifically. OpenStudio cannot read EnergyPlus HVAC. It has a different internal representation of HVAC that makes writing IDF easy, but reading it difficult.

There are OpenStudio versions of most of the reference buildings. These are available via the OpenStudio-Standards ruby gem. At this time, supermarket is not one of them, but it should be there by the end of the year.

I can't seem to get the idf for any commercial reference buildings to open. I have tried opening them in idf editor (e+ 8.8.0) and OpenStudio (1.13.0). I get the errors below.

OpenStudio "The collection is INVALID at strictness level 'Draft', because of the errors: Object level data error of type NoIdd . Error pertains to an object of type 'Catchall', named ''. Additional information about the error type: input data definition is missing or empty. Field level data error of type DataType . Error is in an object of type 'ShadowCalculation', named '', in field 0. Additional information about the error type: field-level data is of an incorrect type. Field level data error of type DataType . Error is in an object of type 'People', named 'Core_bottom People', in field 15. Additional information about the error type: field-level data is of an incorrect type. Field level data error of type DataType . Error is in an object of type 'Sizing:System', named '', in field 17. Additional information about the error type: field-level data is of an incorrect type."

idf editor "Too many errors were found when working on the file. Please examine the file in a text editor to fix."

For IDF Editor, try opening the file with the IDF Editor in the EnergyPlus version that corresponding to the version of the file. Alternatively, you can use IDFVersionUpdater to update it to the most recent version.
