Utility companies offering rebates for energy-efficient building designs often build their automation infrastructure and calculation scripts around a locked, stable version of OpenStudio to guarantee consistent baseline results across hundreds of applicant submittals.
OpenStudio 2.9.1 represents a mature and capable version of the OpenStudio platform that has served the building energy modeling community well. Its combination of the OpenStudio SDK, Application, SketchUp plugin, and CLI provides a comprehensive toolkit for whole-building energy analysis. The version's support for free tools like SketchUp Make 2017 made energy modeling accessible to students, educators, and researchers with limited budgets.
Enables users to run simulations, execute measures (scripts), and manage workflows without a graphical interface. openstudio 2.9.1
Go to Preferences in the OpenStudio App and manually map the directory to C:\EnergyPlusV9-2-0 . Error: SketchUp Crashes on Launch
The advanced approach using OSW files provides maximal flexibility for: The version's support for free tools like SketchUp
Users can create building geometry either:
OpenStudio 2.9.1 provides a stable, reliable framework for building energy modeling, bridging the gap between detailed architectural design (via SketchUp) and powerful energy simulation (via EnergyPlus). Its open-source nature, combined with the capability to model complex HVAC systems and automate workflows with measures, makes it an invaluable asset for sustainable building design.

The OpenStudio ecosystem often integrates with SketchUp for geometry creation. A typical setup stack for this version includes:
Ensure the path to the EnergyPlus directory points exactly to your EnergyPlusV9-2-0 folder. 4. Core Features and Workflow in Version 2.9.1
Fortunately, newer OpenStudio versions (e.g., v3.6.1) can to a large degree safely translate older .osm model files created with version 2.9.1, reducing the migration barrier.
