Hi everyone, I´m modeling a case in OpenStudio for my end of grade work. Since I don't know how to use it I'm following some YT videos. I'm setting the subsurfaces right now, setting the doors and windows. When I set a door or a window OpenStudio automatically set a door in my wall and another door in the plenum... I don't why this happens... I would like to know how can I fix this or how I can delete the plenum door.

i had that same issue. I solved it by removing the plenum space completely but i know that's not the best solution. Updated: I was able to solve this by going to SPACES and then SUBSURFACES and deleting the windows.

Thanks for taking the time for answering. Must be a bug or something but that shouldn't be the best solution. Anyways I'll do that if I don't find an alternative. I have so many questions about this program.

@TheEnergyTudor, thanks for the video here, just to clarify a bit this is specific about geometry creating with FloorSpace JS. I don't know if issue is in FloorSpaceJS and/or OpenStudio. For now I filed in issue in OpenStudio. I'm going to add an alternate answer below for different geometry creation workflow.

The previous answer seemed to be specific to floorSpaceJS. I just wanted to document a different workflow, although it could be applied to FloorSpaceJS plenum spaces when windows are not added in FloorSpaceJS. On the Building Component Library is a very old measure named "Set Window to Wall Ratio by Facade". You can inspect it on its repository.

This is one of our first measures and pre-dates support for plenums in OpenStudio, however the measure has had a number of enhancements added over time. One of these enhancements is a true/false argument to not alter spaces that are not included in the building floor area. In addition to avoiding putting windows in return air or supply air plenums, this will also avoid adding windows to unconditioned plenums or attics that are modeled as zones.

This argument defaults to true but can be changed to false if you for example want to add windows to a garage that may not be part of the building floor area.
