EnergyPlus idd/idf manipulation in Python.

EnergyPlus Python IDD/IDF Utilities

Python library of EnergyPlus IDD/IDF manipulation utilities.

Documentation

Documentation is hosted on ReadTheDocs at https://energyplus-idd-idf.readthedocs.io/en/latest/. To build the documentation, enter the docs/ subdirectory and execute make html; then open /docs/_build/html/index.html to see the documentation.

Installation

This package is deployed to PyPi at https://badge.fury.io/py/energyplus-idd-idf-utilities. To install, simply pip install energyplus-idd-idf-utilities.

Basic Usage

Once installed, the utilities are available for use as a library of functionality to call from Python, or with a very limited (for now) CLI called energyplus_idd_idf. Some example CLI calls:

Get the CLI form:

$ energyplus_idd_idf --help
usage: energyplus_idd_idf [-h] [--idd_check] [--idd_obj_matches IDD_OBJ_MATCHES] [--summarize_idd_object SUMMARIZE_IDD_OBJECT] filename

EnergyPlus IDD/IDF Utility Command Line

positional arguments:
  filename              Path to IDD/IDF file to be operated upon

optional arguments:
  -h, --help            show this help message and exit
  --idd_check           Process the given IDD file and report statistics and issues
  --idd_obj_matches IDD_OBJ_MATCHES
                        Find IDD objects that match the given basic pattern
  --summarize_idd_object SUMMARIZE_IDD_OBJECT
                        Print a summary of a single IDD object by name

This CLI is in infancy and will probably have features added over time

Check an existing IDD file and get basic information:

$ energyplus_idd_idf --idd_check /path/to/EnergyPlus-22-2-0/Energy+.idd 
{
  "message": "Everything looks OK",
  "content": {
    "idd_version": "22.2.0",
    "idd_build_id": "c249759bad",
    "num_groups": 59,
    "num_objects": 881
  }
}

Find all objects which match a certain name pattern:

$ energyplus_idd_idf --idd_obj_matches 'Coil:Cooling*' /path/to/EnergyPlus-22-2-0/Energy+.idd 
{
  "message": "Everything looks OK",
  "content": {
    "pattern": "Coil:Cooling*",
    "matching_objects": [
      "Coil:Cooling:Water",
      "Coil:Cooling:Water:DetailedGeometry",
      "Coil:Cooling:DX",
      "Coil:Cooling:DX:CurveFit:Performance",
      "Coil:Cooling:DX:CurveFit:OperatingMode",
      "Coil:Cooling:DX:CurveFit:Speed",
      "Coil:Cooling:DX:SingleSpeed",
      "Coil:Cooling:DX:TwoSpeed",
      "Coil:Cooling:DX:MultiSpeed",
      "Coil:Cooling:DX:VariableSpeed",
      "Coil:Cooling:DX:TwoStageWithHumidityControlMode",
      "Coil:Cooling:DX:VariableRefrigerantFlow",
      "Coil:Cooling:DX:VariableRefrigerantFlow:FluidTemperatureControl",
      "Coil:Cooling:WaterToAirHeatPump:ParameterEstimation",
      "Coil:Cooling:WaterToAirHeatPump:EquationFit",
      "Coil:Cooling:WaterToAirHeatPump:VariableSpeedEquationFit",
      "Coil:Cooling:DX:SingleSpeed:ThermalStorage"
    ]
  }
}

Get specific details about a single object by name:

$ energyplus_idd_idf /path/to/EnergyPlus-22-2-0/Energy+.idd --summarize_idd_object "Coil:Cooling:DX"
{
  "message": "Everything looks OK",
  "content": {
    "searched_object_name": "COIL:COOLING:DX",
    "field": [
      "A1 : Name",
      "A2 : Evaporator Inlet Node Name",
      "A3 : Evaporator Outlet Node Name",
      "A4 : Availability Schedule Name",
      "A5 : Condenser Zone Name",
      "A6 : Condenser Inlet Node Name",
      "A7 : Condenser Outlet Node Name",
      "A8 : Performance Object Name",
      "A9 : Condensate Collection Water Storage Tank Name",
      "A10 : Evaporative Condenser Supply Water Storage Tank Name"
    ]
  }
}

Testing

The source is tested using the python unittest framework. To execute all the unit tests, simply run nosetests from the project root. The tests are also executed by GitHub Actions for each commit.

Test Coverage

Coverage of the code from unit testing is reported to Coveralls at https://coveralls.io/github/Myoldmopar/py-idd-idf. Anything less than 100% coverage will be frowned upon. :)
