1. Launch: Open an existing Autodesk® Revit® project and click the xStar button in the Add-Ins ribbon to launch xStar.
2. Setup: In the Setup dialog, set high level parameters for your building and choose which Revit data to use for building performance analysis.
3. Verify Thermal Envelope: In the Thermal Envelope dialog, confirm the automatically determined thermal envelope of the building.
4. View Results: In the xStar main window view and interact with building performance metrics such as first cost, total UA, and heating/cooling load.
5. Update Assemblies: The first time you use xStar you'll likely have to build out construction assemblies for the different parts of your building to get accurate building performance metrics. Don't worry, you can save these for next time! Or, you can use our integrated database of construction assemblies which comes prepackaged with cost and energy data.
6. Optimize Your Design: Compare your design to an automatically generated energy code minimum design or create alternative designs by swapping construction assemblies and changing building parameters. Watch building performance change in real-time!
7. Save and Share Results: Export data in csv format for analysis in 3rd party tools, or share xStar files, assemblies, or screenshots with colleagues and clients.
