I’m using the Pollination plugin for Revit to directly export an IDF file from my model. After adding the HVAC system and defining the setpoints, I tried running the energy simulation in EnergyPlus. However, I received an error stating that the design day period is not defined.
After adding the required design day data, EnergyPlus crashed (see figure below). I have also tried different “SimulationControl” settings in EnergyPlus, but the results remain the same.
I would really appreciate any suggestions or advice on how to resolve this issue.
The crash window does not have enough information to know exactly what failed but it seems likely that you still have more simulation parameters that you need to set up.
We have not yet exposed the ability to set up the Project Info (eg. EPW + DDY) or the other EnergyPlus Simulation Parameters (eg. simulation outputs) in the Revit Plugin’s Model Editor yet. So the IDF (and OSM) files that you get from the Model Editor export contain everything except the simulation parameters right now. The expectation now is that you’ll set this all up yourself using either the OpenStudio App or the EnergyPlus IDFEdtior or a text editor.
If you’d like some help with this, can you share the POMF, EPW and DDY file that you want to use (or the URL of the weather on energyplu.net/onebuilding.org)? You can share it via Private Message with @mostapha and me if you don’t want to share the file publicly. If I have that, I can give you an OSM and IDF with everything set up for simulation. I’ll be using the free Ladybug Tools for Grasshopper plugin to set up the simulation parameters and I’ll share the .gh file that takes all of your files and gives you an IDF for simulation in case you want to edit these parameters without having to get deep into IDF text editing.
@mostapha probably has a better idea that I do about when we might finally have fully-supported project information and simulation parameters set up in the model editor. All of the core software infrastructure is there and we just need to expose it.
I’ve added the Project Info using the EPW and DDY files and updated the simulation parameters accordingly. I’ll share the POMF, EPW, DDY, and IDF files with you privately.
Please let me know what has been missing from the final IDF.
Best regards,
Arash.
To any other community members following this public post, we determined that the cause of the problem is that an “Always Off” schedule was assigned for the cooling setpoint and the type limits of the heating schedule were also “Fractional” and therefore not correct.
I am going to reassign this issue to @mingbo because I think this represents a bug in the Rhino/Revit plugin here, which he can address. The plugin should not have allowed you to assign these schedules with fractional type limits for the heating and cooling setpoints.
So I think @mingbo can add an extra check for this in the Room Properties UI and the ProgramType Manager UI to make sure that this situation does not happen again. When you try to assign such a schedule for a setpoint, the Rhino plugin can just prompt you to change the schedule type limits to temperature.
