An even higher level of building design accuracy with Version 2!

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. 

Version 2 key features:

  • Ability to model complex rooms that span multiple floors and complex roofing systems
  • New snapping tools to make it easier to identify what you are snapping to
  • New window array and skylight capabilities
  • Ability to model sensible cooling (CoolSense™) terminal systems
  • Ability to import CAD gbXML (“How to and limitations” document will be included)
  • Significantly improved performance

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.



High-performance 3D modeling for sustainability.

TRACE 3D Plus integrates features focused on ease-of-use, speed and accuracy—saving time and helping engineers and designers make informed and confident decisions.

  • Built-in cloud functionality produces significantly faster simulation
  • Simultaneous calculation & comparison of up to 20 alternatives
  • Comprehensive energy modeling & economic analysis 
  • Demonstrates best options for carbon, renewable energy & cost savings

Model Complex Buildings & Systems with Ease

Accurately model real-world designs, including renewable energy, radiant heating and cooling, and intricate system and central plant designs like those in mixed water heat-exchanger loops.

  • Multi-story, multi-level floors and detailed roofing systems capabilities 
  • Integrated equipment selection for true as-built model simulation
  • EnergyPlus™ engine drives and substantiates accuracy 

Visually dynamic, intuitive workflows.
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. And the guided experience in TRACE 3D Plus matches real world design practices.

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.






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






Data Visualizer allows you to analyze models in tremendous detail, down to time step for hundreds of selectable variables. Use this chart to compare features with TRACE™ 700.
