Additional methods for removing EMS objects:

model.getEnergyManagementSystemActuators(&:remove)
model.getEnergyManagementSystemConstructionIndexVariables(&:remove)
model.getEnergyManagementSystemCurveOrTableIndexVariables(&:remove)
model.getEnergyManagementSystemGlobalVariables(&:remove)
model.getEnergyManagementSystemInternalVariables(&:remove)
model.getEnergyManagementSystemMeteredOutputVariables(&:remove)
model.getEnergyManagementSystemOutputVariables(&:remove)
model.getEnergyManagementSystemPrograms(&:remove)
model.getEnergyManagementSystemProgramCallingManagers(&:remove)
model.getEnergyManagementSystemSensors(&:remove)
model.getEnergyManagementSystemSubroutines(&:remove)
model.getEnergyManagementSystemTrendVariables(&:remove)

You could also extend the solution provided by @Eric Martin to multiple EMS objects.

# remove EMS objects model.getEnergyManagementSystemSensors.each do |ems_obj| ems_obj.remove end model.getEnergyManagementSystemActuators.each do |ems_obj| ems_obj.remove end model.getEnergyManagementSystemGlobalVariables.each do |ems_obj| ems_obj.remove end

etc... for other EMS objects
