#configure_workflow_for_scenario(base_workflow, scenario) ⇒ Object

Based on the MeasureIDs defined by the Scenario, configure the workflow provided using the default measure arguments defined by the lib/buildingsync/makers/workflow_maker.json

Parameters:

  • base_workflow (Hash) —

    a Hash map of the @workflow. DO NOT use @workflow directly, should be a deep clone

  • scenario (BuildingSync::Scenario) —

    a Scenario object

run osws - running all scenario simulations

Parameters:

  • only_cb_modeled (Boolean) (defaults to: false) —

    used to only run the simulations for the cb_modeled (baseline) scenario

  • runner_options (hash) (defaults to: { run_simulations: true, verbose: false, num_parallel: 7, max_to_run: Float::INFINITY })

TODO: Update this as I believe no longer will work as expected, keys being searched for

by the @facility_xml['key'] don't make sense.

set argument details, used when the condition

Parameters:

  • workflow (Hash) —

    a hash of the openstudio workflow

  • argument (Hash)
  • measure_dir_name (String) —

    the directory name for the measure, as it appears in any of the gems, i.e. openstudio-common-measures-gem/lib/measures/

  • measure_name (String)
