Hi,

I am trying to generate EnergyPlus idf from the xml file attached here. However, I am getting errors related to ducts. I would appreciate any help on how to resolve this.

To add a little more context to this, I have downloaded the xml files from EUSS data here. EUSS data seems to be generated using ResStock 2.6.0-beta and I tried to install this version but seems this version is not available online. I would appreciate any additional insights

Best,

I see that your HPXML was generated by ResStock and you are trying to run it through OpenStudio-HPXML. Note that the version of OpenStudio-HPXML matters because the inputs sometimes change with a new version.

The safest way to run OpenStudio-HPXML is to use the version that is embedded into your version of ResStock. It can be found inside the resources/hpxml-measures directory. That will ensure you get the same results that ResStock produced.

If instead you want to want to take a ResStock-generated HPXML file and run it with the latest version of OpenStudio-HPXML, then yes, you'll have to fix the two errors. The first one is because you now need a SystemIdentifier element for each Ducts element (see here as an example). The second one is because the Quantity elements were renamed to Count (see here for example). Both of these were input changes in OpenStudio-HPXML v1.5.0.
