TRACE® 3D Plus Version 3 is the newest release for this next generation building design and analysis software program. It 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. 

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.

The Latest Version 3 Software Update is Here!

Our latest TRACE® 3D Plus Version 3 updates amp up the flexibility in building design and analysis, giving you the ability to work smarter and more collaboratively, but never harder.

Visit the Download section below to begin the v3.20.18 update, including:

New File Support - Open and run files from network locations

New Accelerated Report Preview Performance for Larger Files:
- Quick view option allows the user to view reports while they load rather than waiting for all reports to load completely
- 'Room' and 'Zone' filtering options for Loads by Component reports allows select data to be loaded rather than the entire model

Improved Skylights can be created as a percentage of the roof area making complex skylights much easier to create

Improved gbXML Importing including cases with upside down surfaces and discontiguous floor slabs

PLUS adjustments to load design reports to improve accuracy and clarity
