Export To OpenStudio

Component Index > Honeybee > 10 | Energy | Energy > Export To OpenStudio

Use this component to export HBZones into an OpenStudio file, and run them through EnergyPlus.
The component outputs the report from the simulation, the file path of the IDF file, and the CSV result file from the EnergyPlus run, and two other result files that record outputs in different formats.

Inputs

NameIDDescriptionType
north_north_Input a vector to be used as a true North direction for the energy simulation or a number between 0 and 360 that represents the degrees off from the y-axis to make North. The default North direction is set to the Y-axis (0 degrees).Goo
_epwWeatherFile_epwWeatherFileAn .epw file path on your system as a text string.Goo
_analysisPeriod__analysisPeriod_An optional analysis period from the Ladybug_Analysis Period component. If no Analysis period is given, the energy simulation will be run for the enitre year.Goo
_energySimPar__energySimPar_Optional Energy Simulation Parameters from the "Honeybee_Energy Simulation Par" component. If no value is connected here, the simulation will run with the following parameters: 1 - 6 timeSteps per hour 2 - A shadow calculation that averages over multiple days (as opposed to running it for each timeStep) 3 - A shadow calculation frequency of 30 (meaning that the shadow calulation is averaged over every 30 days) 4 - A maximum of 3000 points used in the shadow calculation. (This may need to be higher if you have a lot of detailed context geometry) 5 - An colar energy calculation that includes both interior and exterior light reflections. 6 - A simulation including a zone sizing calculation, a system sizing calculation, a plat sizing calculation, and a full run of the energy use ofver the analysis period. The simulation is not run for the sizing period by default. 7 - A system sizing period that runs from the extreme periods of the weather file and not a ddy file. 8 - City terrian.Goo
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::Script variable exportToOpenStudioGoo
_HBZones_HBZonesThe HBZones that you wish to write into an OSM file and/or run through EnergyPlus. These can be from any of the components that output HBZones.Goo
HBContext_HBContext_Optional HBContext geometry from the "Honeybee_EP Context Surfaces." component.Goo
simulationOutputs_simulationOutputs_A list of the outputs that you would like EnergyPlus to write into the result CSV file. This can be any set of any outputs that you would like from EnergyPlus, writen as a list of text that will be written into the IDF. It is recommended that, if you are not expereinced with writing EnergyPlus outputs, you should use the "Honeybee_Write EP Result Parameters" component to request certain types of common outputs.Goo
additionalStrings_additionalStrings_THIS OPTION IS JUST FOR ADVANCED USERS OF ENERGYPLUS. You can input additional text strings here that you would like written into the IDF. The strings input here should be complete EnergyPlus objects that are correctly formatted. You can input as many objects as you like in a list. This input can be used to write objects into the IDF that are not currently supported by Honeybee.Goo
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::Script variable exportToOpenStudioGoo
_writeOSM_writeOSMSet to "True" to have the component take your HBZones and other inputs and write them into an OSM file. Note that only setting this to "True" and not setting the output below to "True" will not automatically run the file through EnergyPlus for you.Goo
runSimulation_runSimulation_Set to "True" to have the component generate an IDF file from the OSM file and run the IDF through through EnergyPlus. Set to "False" to not run the file (this is the default). You can also connect an integer for the following options: 0 = Do Not Run OSM and IDF thrrough EnergyPlus 1 = Run the OSM and IDF through EnergyPlus with a command prompt window that displays the progress of the simulation 2 = Run the OSM and IDF through EnergyPlus in the background (without the command line popup window). 3 = Generate an IDF from the OSM file but do not run it through EnergyPlusGoo
openOpenStudio_openOpenStudio_Set to "True" to open the OSM file in the OpenStudio interface. This is useful if you want to visualize the HVAC system in OpenStudio, you want to edit the HVAC further in OpenStudio, or just want to run the simulation from OpenStudio instead of Rhino/GH. Note that, for this to work, you must have .osm files associated with the OpenStudio application.Goo
fileName_fileName_Optional text which will be used to name your OSM, IDF and result files. Change this to aviod over-writing results of previous energy simulations.Goo
workingDir_workingDir_An optional working directory to a folder on your system, into which your OSM, IDF and result files will be written. NOTE THAT DIRECTORIES INPUT HERE SHOULD NOT HAVE ANY SPACES OR UNDERSCORES IN THE FILE PATH.Goo
