Hello all,

I use the create_doe_prototype_building measure which seems to accept only a predefined list of epws. Tried to combine it with measure ChangeLocation but then it complains about not having a stat file. In the end I would just like to run the model with a custom epw. It seems basic so the answer may be out there but I could not find it, sorry about that.

Is there a simpler way ? My tentative workflow below

{ 
"run_directory": "run_FR_SFH_2013_system01", 
"measure_paths": [ "../../OpenStudio-HPXML" ], 
"file_paths": [ "../data" ], 
"steps": [ 
  { "arguments": 
    { "building_type": "SmallOffice", "template": "DOE Ref 1980-2004", "climate_zone": "ASHRAE 169-2013-5B", "epw_file": "MONTEREY_724915_CZ2010.epw" }, 
    "measure_dir_name": "create_DOE_prototype_building" }, 
  { "arguments": 
    { "weather_file_name": "Paris_2021.epw", "climate_zone": "ASHRAE 169-2013-5B", "set_year": "2021", "use_upstream_args": true, "epw_gsub": "Do Nothing" }, 
    "measure_dir_name": "ChangeBuildingLocation" } ], 
"run_options": { "fast": true, "skip_expand_objects": true, "skip_energyplus_preprocess": true } }

Thank you

Thanks for the answer. It looks like I am on the right track. It feels to me that there should be a way to do all at once.

My next goal is to try to play with different types of heating systems: I have the foudn the measure create typical doe building from model. As far as I understood this measure has some similarities but does not create themodel from scratch. Is the right way to add this step to my workflow [create_DOE_prototype_building, create_typical_doe_building_from_model, changeBuildingLocation] ? I have not tried yet.

The ChagneBuildingLocationmeasure doesn't use OpenStudio Standards. It parses, the weather file to update weather file and site object in OpenStudio. This doesn't seem to be issue with not finding STAT or DDY file, but about parsing the EPW file. Here is link wi where the weather file is used https://github.com/NREL/openstudio-co...

Something you can try is to run the prototype measure in the OpenStudio Application, then try to set EPW there and see if it works or if it hits a similar issue.

My error, the epw had a problem indeed. Thanks for your help. I am modifyin gthe answer as it is not pertinent. I have another question though on how to play with the type of HVAC system.

I have run the DOE Prototype measure and then the ChangeBuildingLocation measure after that. You do have to provide an EPW, DDY, and STAT file for the alternate location. The Stat file is used by ChangeBuildingLocation to get the ClimateZone and water main temperatures. You should run the Prototype measure for the same climate zone as. your custom weather file so there are reasonable representations of system efficiencies, which will be based on the original weather file.

Hi David for the changing building location measure in PAT, the only input is the weather file name not location /file address. How can I find the name of one specific weather file ?
