OpenStudio
An open-source software development kit for building energy modeling.
Overview
OpenStudio is a collection of software tools to support whole-building energy modeling using EnergyPlus. It includes a graphical interface for creating and editing building geometry, a library of building components, and tools for running simulations and analyzing results. It is developed and maintained by the National Renewable Energy Laboratory (NREL).
✨ Key Features
- SketchUp Plug-in for 3D geometry creation
- Graphical application for model editing and simulation management
- Parametric Analysis Tool for running simulations with multiple design variations
- Results viewer for analyzing simulation output
- OpenStudio Measures for automating modeling tasks
- Integration with Radiance for daylighting analysis
🎯 Key Differentiators
- Free and open-source
- Directly developed and supported by NREL
- Extensible through OpenStudio Measures
Unique Value: Provides a comprehensive, free, and open-source ecosystem for whole-building energy modeling with EnergyPlus, fostering a collaborative and extensible environment.
🎯 Use Cases (4)
✅ Best For
- Energy modeling for green building certifications
- Large-scale building stock analysis
💡 Check With Vendor
Verify these considerations match your specific requirements:
- Users who are not comfortable with a component-based modeling approach
- Projects that require a very simple, non-extensible modeling tool
🏆 Alternatives
Offers a more scriptable and extensible environment than many commercial GUIs for EnergyPlus, but may have a steeper learning curve for some users.
