Hi everybody,

For speeding up EnergyPlus simulation we think to divide runperiod (1 period of 1 year) into multiple runperiods (12 periods of 1 month) and create corresponding idf files for launching (12) EnergyPlus simulation in parallel. I don't know if someone did already the same thing and if the results would be different compared with the simulation of 1 period of 1 year?

Any idea?

Thanks a lot!

Hello, Could some one can tell me how can I assign the building unit to the spaces using ruby scripts. I tried to do something as follows, but it doesn't work

class AssignBuildingUnitToSpaces < OpenStudio::Ruleset::ModelUserScript

  def name
    return 'Assign building unit to spaces based on spaces name'
  end

  def arguments(model)
    args = OpenStudio::Ruleset::OSArgumentVector.new
    return args
  end

  def run(model, runner, user_arguments)
    super(model, runner, user_arguments)

    if !runner.validateUserArguments(arguments(model), user_arguments)
      return false
    end

    spaces = model.getSpaces

    unit = OpenStudio::Model::BuildingUnit.new(model)
    unit.setBuildingUnitType("Residential")
    spaces.each do |space|
      space_name  = [] # space name as a list
      if space.name.to_s.include? '_'
          space_name = space.name.to_s.split('_') # split space name
      else
          space_name[0] = space.name.to_s
      end

      if ["A","B","C","D","M"].any? {|prefix| space_name[0].include? prefix}
        if space.buildingUnit.empty? || !space.buildingUnit.get.name.to_s.include?(space_name[0])
            unit.setName(space_name[0])
            space.setBuildingUnit(unit)            
        end          
      end      
    end

    return true
  end
end

I am a very newbie in using OpenStudio and Openstudio SDK.

Hello,

When using eppy to run energyplus model, I got the following error. Could anyone tell how to resolve this please? I am using EnergyPlus 9.1.0 and eppy 0.5.51. Indeed, the model was successfully run using EP-Launch.
