What is xStar?

Answer: xStar is an easy-to-use software that provides real-time estimates of cost, energy use (in development), and carbon emissions (in development) of buildings. It integrates directly with existing architectural design software (i.e. Autodesk® Revit®) as a plugin.

How can I use xStar?

Answer: xStar is both a design and sales tool. It provides real-time feedback on a design’s building performance and allows you to easily compare and swap construction assemblies. This helps you answer questions in client meetings or at the design desk like:

• Where can we reduce cost/energy/carbon in our design?

• How does my building compare to code minimum construction?

• What are the benefits of using an alternate wall/roof/floor construction?

• How much insulation should I use?

• What happens if the cost of lumber increases next year?

• and more…

Does xStar work for residential and commercial buildings?

Answer: Right now, xStar’s analysis is tuned for residential buildings only. However, users can add their own commercial construction assemblies and data.

What design software does xStar support?

Answer: xStar currently integrates with Autodesk® Revit® 2023, 2024, and 2025.
