Openstudio 2.9.1 ✦ Confirmed & Authentic

A key consideration for users relying on the SketchUp integration is version compatibility. OpenStudio 2.9.1 is specifically compatible with SketchUp Make 2017, the most up-to-date free version of SketchUp available at the time of release. The OpenStudio SketchUp Plugin v1.0.0 and above may work with SketchUp 2017 and OpenStudio 2.9.1, though this configuration is not formally tested or supported.

A key concept in the OpenStudio workflow is the . This is a JSON file that defines a sequence of Measures (self-contained scripts that modify an energy model) to be run. The OSW allows for the creation of repeatable, automated simulation processes. For example, a basic simulation can be run from the command line using a Ruby script: openstudio resources/run_simulation.rb -x tests/base.xml . More advanced tasks are handled with an OSW file: openstudio run -w resources/template.osw .

The open-source nature of OpenStudio ensures that version 2.9.1 remains available for download and use in perpetuity, even as the platform continues to evolve. This permanence makes it a valuable reference point in the history of building energy modeling software and a useful tool for specific applications that require its particular feature set.

Released in late 2019, OpenStudio 2.9.1 is a cross-platform collection of software tools used to create and manage building energy models using the EnergyPlus simulation engine. A key consideration for users relying on the

: While the SDK is the core, tools like the OpenStudio SketchUp Plug-in have historically allowed for the visual creation of 3D building geometry, which remains a cornerstone for users who prefer a graphical approach to thermal zoning. Technical Impact and Sustainability

Users can create building geometry either: A key concept in the OpenStudio workflow is the

The OpenStudio Application is the primary graphical user interface included with version 2.9.1. This interface allows users to define building components including construction assemblies, materials, HVAC systems, schedules, internal loads, and manage the entire model. The application provides a visual workflow that guides users from geometry creation through simulation and results analysis.

For engineering firms with vast libraries of pre-built building templates, migrating thousands of components to newer versions can introduce unforeseen errors or discrepancies in energy consumption trends. Maintaining a legacy 2.9.1 environment ensures project continuity. Summary of Best Practices for Version 2.9.1
