The building does not appear to have any conditioned zones. Make sure zones have thermostat with appropriate heating and cooling setpoint schedules.

Hello,

I am trying to run a SDK openstudio version. I am not that familiar with it and if I have missed something please do point it out. So currently I have a osm file that has been created using a json which has rooms. In the osm I see the space and space types. I created a osw file with the create_typical_doe_building and I got some errors regarding setstandardbuilding type so I added a few measures that I found online. Please see the osw file below.

The conditioned zones error has me stuck. I am not trying to do any modifications for the inputs right now so just want the osm file to run and create a report. The osm file does run just fine in the application if the thermal zones are added but in the code the measure should do the same so I am not sure whats happening.

{
  "seed_file": "all_rac_basic_model.osm",
  "file_paths": [
    "./weather"
  ],
  "measure_paths" : [ "./measures" ],
  "weather_file": "USA_CA_San.Francisco.Intl.AP.724940_TMY3.epw",
  "steps": [
     {
      "arguments": {
        "__SKIP__": false
      },
      "measure_dir_name": "Set Climate Zone from Weather Data"
    },
     {
      "arguments": {
        "__SKIP__": false
      },
      "measure_dir_name": "Space Type and Construction Set Wizard"
    },
      {
      "arguments": {
        "__SKIP__": false
      },
      "measure_dir_name": "CreateandAssignThermalZonesforUnassignedSpaces"
    },
    {
      "arguments": {
        "__SKIP__": false
      },
      "measure_dir_name": "Set Thermostat Schedules"
    },
    {
      "arguments": {
        "__SKIP__": false
      },
      "measure_dir_name": "CreateTypicalDOEBuilding"
    }
  ]
}

Thank you

I'm not an expert here, but it looks to me that the order of the measures might be suspect? I would think that you need to apply the CreateTypicalDOEBuilding before, e.g., assigning thermostats.

@shorowit Ah yes, I thought that too but no luck cuz the zones error is coming from the CreateTypicalDOEBuilding measure so as soon as that runs BOOM error!

@dganesh The thermostat measure isn't doing anything without arguments. It only assigns schedules that are already in the model to thermal zones. The create_typical will assign thermostats for space types that it recognizes. Does your original model have thermal zones in it and not just spaces. Nothing in that workflow will add thermal zones if they are not already in the model.

Another question will be coordinating version of OpenStudio with the measure. The repository I gave a link to in the answer is for OpenStudio 3.1.0.

Are you getting through the measure and having an EnergyPlus failure. Here are some initial thoughts - If you have space types in your model that are not setup with standards building type and space type create typical won't work as expected. If you don't have space types at all then space type wizard would add a whole building office as catch all space type. - Make sure when setting the weather file that it is is properly setting the ASHRAE climate zone that is needed by create typical measure. - The set Thermostat Schedules needs to refer to schedules already in the model, but you can just remove this since create_typical should add thermostats for you.

You may want to use this workflow as a starting point. You can check this out and run it with OpenStudio 3.1.0 to test your computer environment. Note that this workflow uses an empty seed and brings in model through an argument in the measure. It was setup that way so when setup as a parametric analysis project the model can be a variable that changes. You can keep it setup like it is or remove the replace model measure and use your model in place of the currently empty seed model. https://github.com/DavidGoldwasser/osw2osa/blob/pre_bundled/run/workflows/osm_typical/in.osw

Look at the out.osw file for log messages for each measure to give an indication of what might have gone wrong.

Hey I tried using your osm file("geo_stub_space_types.osm") from github link and got this error with my osw file with just the typical measure. . Error is in an object of type 'OS:Coil:Cooling:DX:SingleSpeed', named 'Zone SecondarySchool Kitchen C - Story B1 PSZ-AC 1spd DX AC Clg Coil 16kBtu/hr 14.0SEER', in field 22. Error is in an object of type 'OS:Coil:Cooling:DX:SingleSpeed', named 'Zone SecondarySchool Kitchen C - Story B1 PSZ-AC 1spd DX AC Clg Coil 16kBtu/hr 14.0SEER', in field 16.

I also added standard building type and space type in my osm model but I still got the original error with the conditioned zone. And i only used the typical measure with this.
