OpenStudio Plug-in Kickstart

Extensions
1

I’m just starting to dig into the OpenStudio plug-in. I’m wondering if someone can provide pointers to resources, tutorials, or other aids. Thanks.

I asked Gemini AI “Resources, tutorials, or other aids for the SketchUp OpenStudio extension”, it replied …

Finding high-quality resources for the OpenStudio SketchUp Plug-in is essential because the workflow is split between SketchUp (for geometry) and the OpenStudio Application (for energy systems).

I [Gemini] have curated the most direct documentation and expert training sources available for the 2025/2026 modeling environment.

1. Official Documentation & Guides

The OpenStudio Coalition (the group currently maintaining the plug-in) provides the most up-to-date technical references.

  • OpenStudio Coalition User Docs : This is the “source of truth” for the interface. It includes detailed guides on the Inspector Window, Render Modes (by construction, boundary condition, etc.), and how to use the Surface Matching tool.
  • OpenStudio SketchUp Plug-in Wiki : Critical for checking the Version Compatibility Matrix. It ensures your version of SketchUp (e.g., 2024 or 2025) matches the correct version of the OpenStudio Application.
  • NREL Quick Start PDF : A highly visual, interactive PDF that walks through the “Envelope-to-Application” workflow.

2. Video Tutorials & YouTube Channels

Because OpenStudio geometry can be finicky (e.g., “sticky” geometry or thermal zone leaks), watching the workflow in real-time is helpful.

  • NREL OpenStudio Channel : Though some videos are older, their “Basic Workflow Guide” series remains the gold standard for understanding how to draw spaces, project fenestration (windows), and use the Spaces From Diagram tool.
  • Big Ladder Software YouTube : They focus on professional-grade EnergyPlus and OpenStudio training. Look for their webinars on “OpenStudio Launch Pad.”
  • The Energy University (BIM2SIM) : Offers very specific tutorials on moving from SketchUp geometry into the HVAC and Plant Loop side of OpenStudio.

3. Professional Training Courses (2026)

If you need structured learning, these organizations offer live and on-demand certifications.

Provider Course Name Focus
Big Ladder Software OpenStudio Launch Pad A 2-day deep dive into envelope, internal gains, and HVAC. Next sessions are scheduled for March/April 2026.
Energy-Models.com OpenStudio Step-by-Step A modular course covering everything from floor plan setup to running simulations.
BIM2SIM (Teachable) OpenStudio for Professionals Advanced training including Measures (Ruby scripts) to automate your SketchUp workflow.

4. Key Utilities & Tools

  • Building Component Library (BCL) : An online repository you can access directly within the SketchUp plug-in to download pre-made “Measures,” construction sets, and space types.
  • Unmet Hours : The primary Q&A community for OpenStudio users. If you run into a specific error or geometry “leak,” this is where the experts troubleshoot.

5. SketchUp Plugin Specific Resources

(Also compiled by the Gemini AI)

To address the specific focus on the SketchUp Plug-in tools rather than the standalone OpenStudio Application, here are the resources and specific toolsets dedicated to geometry creation and manipulation.

SketchUp-Specific Plug-in Tools and Scripts

  • OpenStudio User Scripts (Ruby Menu) : Accessed via Extensions > OpenStudio > User Scripts. These are Ruby-based automations built specifically for the SketchUp environment. Key scripts include:

    • Alterations: Tools to add windows at specific ratios or remove all windows across a selection.
    • Reports: The “Surface Search” report, which identifies unassigned or “orphan” geometry that the standalone app cannot process.
    • Space Registration: The “Project Loose Geometry” script for forcing standard SketchUp lines into recognized OpenStudio Space objects.

  • The Inspector Tool : The primary interface for assigning Space Types and Thermal Zones to SketchUp groups. This allows for data assignment without leaving the 3D modeling environment.

  • Set North Axis Tool : A specialized tool within the SketchUp toolbar. OpenStudio ignores standard SketchUp solar north settings; this tool must be used to align the simulation’s coordinate system.

Plugin-Specific Workflow Guides

SketchUp OpenStudio Geometry Cleanup Checklist

Check for “Internal” Faces: Ensure no faces are floating inside a space without being assigned as a partition.

Surface Matching: Run the Surface Matching tool (found under Extensions > OpenStudio > User Scripts) to ensure adjacent walls are correctly identified as “Internal” rather than “Outdoor.”

Intersection: Always use the Intersect Faces tool across the entire model to ensure that overlapping surfaces are properly subdivided for heat transfer calculations.

Orientation Check: Use the Render by Surface Normal mode to verify that all face normals point outward. Purple faces (back sides) should not face the exterior.

Space Boundaries: Confirm that all geometry is contained within an OpenStudio Space group; loose geometry outside of these groups is ignored by the simulation engine.

Dan:

Thanks for an obvious resource I didn’t think of. The first set of info you got is most OpenStudio, not the plugin, but it’s a start. The cleanup checklist looks very useful.

Thanks!

that’s a lot of infos formatted by AI, it reads like optical noise to me, I had to ask the forum’s AI to give me a summary :innocent:

Off-topic about general AI faults & etc.

Yup, every dang day I have to remind the AI to be more concise.
I am not impressed when it tries to inundate me with excess text to read (i.e., “spewing”.)
This and also that the AI tends to go “off the rails” into tangents and often makes mistakes.

When I do know when the AI “misses the mark” I can call it to order and sometimes get a better secondary response. But in this case I do not know enough about the OpenStudio plugin for SketchUp. (I do know generally that it is for shadow studies and how sunlight affects indoor environments, etc.)

(After reopening the AI convo, Dan says to Gemini) Response in the forum is: "Thanks for an obvious resource I didn’t think of. The first set of info you got is mostly OpenStudio, [the standalone app], not the plugin, but it’s a start. "

The Gemini supplied SketchUp Specific lists have been moved to the second post above.

Or you know, you could have just responded in your own words…

Alright it seems my attempt to be helpful (and imply how an AI search can lead to information) is not being well received.

Should Dan just delete his posts?

  • YES
  • NO
  • WHO CARES?

For someone who is a pedant I’m surprised you are using AI to respond, especially when it is verbose and often incorrect…

Your are very welcome. I also was interested to know what was available out there.

I requeried Gemini for SketchUp Specific resources.
The results are all now listed in the second post as section 5.

Again you are welcome Steve. Despite the critical distractions, my main goal was to be helpful and have the search results serve as a resource list. (The forum has a bookmark feature so interested members can save a private link to this topic thread.) Secondarily, an example of how the AI can speed up web searches.

As evidenced by the readers clicking the links, I’m glad to see my posts are proving useful to those researching OpenStudio.

You’ll need to also learn OpenStudio. The SU plugin is great for getting the project ready but it doesn’t perform the energy calculations within the SU environment.
Feel free to reach out if you have any questions, I used to use this on a daily/weekly basis but it has dropped off a bit over the last 2 years simply because my role has evolved.

Yeah–I got that far, then the OS interface just tired me out. :slight_smile: And I haven’t found any really good tutorials, at least not yet.

Thanks for your offer. You may be hearing from me.
