If you want to create an OpenStudio Model (*.osm
) you need the full OpenStudio Suite.
Don't get confused, there are two different products:
- The OpenStudio Suite(www.openstudio.net / GitHub), from NREL, which has a Sketchup Plugin, the OpenStudio Application, the Parametric Analysis Tool, and the Results Viewer, and the API/SDK. This allows the creation of OpenStudio Model -
*.osm
file - that you can open in the OpenStudio Application. - The Legacy OpenStudio Plugin (formerly (?) GitHub NREL/legacy-openstudio) - now maintained by Big Ladder Software if I understand correctly from this answer - which is a Sketchup Plugin to view and modify the geometry of EnergyPlus
*.idf
files and has some extra capabilities like launching simulations directly from Sketchup and viewing select results.
The OpenStudio Suite is more comprehensive, but the Legacy OpenStudio Plugin is still very relevant if your goal is to work with pure EnergyPlus *.idf
files.
One caveat of the OpenStudio Suite is that it cannot reverse translate - meaning translate an *.idf
file to an *.osm
file - many aspects of an *.idf
file. Rule of thumb: anything else than geometry, internal loads and schedules will not be translated. So if you have an already created EnergyPlus model (*.idf
), then the Legacy OpenStudio Plugin is a tool of choice!
Additionally, when you use either of these two products, do not use Sketchup's built-in "Save/Save As" command but the one provided by the plugin. For example, if you use the Full OpenStudio Suite, use the "Save OpenStudio Model" button of the OpenStudio toolbar, as highlighted in the OpenStudio SketchUp Plug-in Interface Guide
Hi,
You can save your OpenStudio model by 1) Files:Save as: .osm or by 2) OS icon Save the OpenStudio as a new file .osm .
Note that if you save your file initially in .skp, it will not be possible to open your model in .osm file
Is there an error message that appears?
Hi Borm, by 2) OS icon Save the OpenStudio as a new file .osm . As I said the Legacy version I have installed doesnt have this Icon
by 1) Files:Save as: .osm , it doesnt allow to select any file type, save as is blank!
I think Julien answers the question.
