TRACE® 3D Plus Load Design

TRACE® 3D Plus Load Design
TRACE® 3D Plus Load Design is the next evolution of the globally used and trusted TRACE® 700 Load Design software. This 3D design platform makes accurately sizing your HVAC systems faster and easier at any desired level of fidelity. We've taken our 50 years of HVAC systems design and software simulation knowledge and combined it with the U.S. Department of Energy's state-of-the-art EnergyPlus® simulation engine. The result is a platform that makes right sizing HVAC systems intuitive and visually dynamic with an easy to understand workflow that's less error prone. Try the new TRACE 3D Plus platform today and get accurate sizing results in a fraction of the time.
The latest Version 6 software is here!
In the Version 6.2 release, you’ll find an improved user experience, an updated F1 Help platform, and additional AWHP functionality. These updates are possible due to continued comments and requests from users.
Visit the Download section below to begin the V6.2 update, including:
- Improved Spreadsheet editor functionality
- Addition of the Equipment Energy Consumption Report, along with various report updates
- gbXML Import updates and improvements
- Live updates and more data visible when changing Construction members
Trace 3D Plus Load Design Features

Enjoy the same intuitive ease and intelligent defaults that made TRACE 700 so popular while the schematically configurable system/plant layout and control provides a deeper level of customization to match real world design.
Save even more time on every project with the extended library and template architecture to include dozens of full building templates that make getting quick and highly accurate results for most commercial building types 30 to 40% faster than its predecessor.

The thousands of built-in libraries and templates were created by researching hundreds of industry standards, studies completed by national labs or other trusted industry resources. The 3D building elements are infused throughout the interface with the full breadth of the libraries and templates for an unparalleled design experience that can be visually verified.
And the best part is that all load design models are completely scalable and seamless should the need arise for an upgrade to the full energy or economic analysis platform!

TRACE 3D Plus does more than just spit out ASHRAE Heat Balance toolbox load calculations. TRACE integrates Trane’s vast industry experience and considers worst case design of every component in the building model to give the modeler the ultimate control of all design considerations or factors of safety.
Whether modeling today’s sophisticated radiant designs, complex VRF configurations, or high performance VAV systems, TRACE 3D Plus will help guide the designer through the process.
