A new level of building design accuracy 

TRACE™ 3D Plus is a next generation building design and analysis software program that delivers faster, more accurate results through a seamless workflow that closely aligns with today's building process. The latest HVAC systems and controls can be modeled quickly, precisely and with the intricacies of today's many building applications. TRACE 3D Plus is built on the U.S. Department of Energy's EnergyPlus engine and enhanced with Trane's industry leading expertise to help designers validate and interpret projects with confidence and clarity. All of these new features plus a more robust support experience to get you up and running quickly. 

Faster modeling process with visually dynamic workflows

TRACE 3D Plus allows you to move from project plan to load design to energy and economic analysis all through the same project file and interface. Import 3D models directly from CAD using Green Building XML (gbXML), or import floor plans and trace over using the draw tools. Easily create and validate your architectural design and HVAC systems in 2D or 3D. 

Create schedules faster with graphical plotting and drag-and-drop features.

Use pre-configured building themes and thousands of pre-loaded and scalable libraries and templates.

Schematically configure systems and plants easily with built-in systems validation and intelligence.



TRACE 3D Plus intuitive interface.
A highly adaptable platform that's customizable to your desired level of detail. Built-in systems knowledge provides early detection of potential problems in your design. Defaults are pre-programmed into the software to reduce errors and save valuable time.

Graphic rich reports communicate easy-to-understand information and insights for you to share with your project team.



Illustrates real-world complexities.
Accurately model real-world designs, including renewable energy, radiant heating and cooling, and complex chilled- and hot-water systems like those in mixed water heat-exchanger loops.

Reliable results.
TRACE 3D Plus ensures greater equipment modeling accuracy by allowing you to import equipment data directly from Trane Official Product Selection Software (TOPSS™) or from a spreadsheet performance data file.





Data Visualizer allows you to analyze models in tremendous detail, down to time step for hundreds of selectable variables.


Trial software will be available soon to allow you to see the power in the next generation of modeling software—TRACE 3D Plus.
