How to make a model with cogeneration in OpenStudio?

savecancel

I don't see PV in the GUI? Is it available in the API only?

I should have clarified, It wasn't added until 1.9.1. Dan added a user script in the plugin and it will render as purple grid if surface is assigned as PV, but doesn't show in OpenStudio GUI, except for in the standard report. I'm also working on a measure to put on BCL. Maybe I'll try to post quick video next weekend. I also want to post something on ZoneMixing and ZoneVentilationDesignFlowRate (which are both API only).

Thank you, I saw a possibility to write it in IDF file but I didn't know how to use it with OpenStudio.

The PV measure in 1.9.2 doesn't work, it's missing a critical object: ElectricalLoadCenter:Generators. I've opened an issue here

@Julien Marrec, I assume you are referring to the user script in the SketchUp plugin? I haven't posted the OpenStudio based PV measure on BCL. There is an old EnergyPlus PV measure.

@macumber can confirm this but I think this gets generated for you on forward translation to IDF. I confirmed that I don't have this object in my OSM file but it is in the IDF from an earlier run, in which I dod confirm PV production.

@Dubravka I'll post a measure soon that will take an argument for you to point to an IDF file, and it will just drop it in for you. This won't work in cases where you need to remove or alter IDF objects generated by OpenStudio forward translation. But for simple cases where you just want to add in had made IDF objects, it will work.

@David Goldwasser is right that object is not included in the OpenStudio model, it is generated on translation to IDF.

@David Goldwasser Thank you, I am looking forward to your post.

@David Goldwasser Can I look forward to some announcement about the measure that will take an argument to point to an IDF file and just drop it in?

@Dubravka thanks for the reminder on this, I'll try to have it by Monday.

@David Goldwasser Thank you very much, I'm really looking forward!

Just posted Inject IDF Measure to BCL. You should be able to see it from the OpenStudio application. When you browse it using "Find BCL Measure" Look under "Whole Building/Space Types". It can be used for any type of object but I have to place it somewhere in the taxonomy. You may have to advance to page new to see this measure, newest measures are listed last.

The measure pretty much works as if you did a copy and paste into the IDF file prior to passing the IDF to EnergyPlus.

@David Goldwasser Thank you!

@David Goldwasser Hello! I’ve been using measure ‘Inject idf objects’ and I have a problem. When I use idf files made in EnergyPlus measure works fine, but when I want to use idf file made from osm file it seems that measure just ignore that file. Am I making some mistake or measure can work only with idf made directly in EnergyPlus? Thank you in advance.

@David Goldwasser I have found mistakes in my file. Sorry for disturbing.
