TRACE 700 is currently being phased out.

TRACE® 700 is Trane’s legacy platform for the current version of the award-winning TRACE® 3D Plus design and analysis software tool that helps engineering professionals optimize their building design and operation though simulation.

TRane Air Conditioning Economics, better known as TRACE®, has been a leading tool for building simulation for nearly 50 years. TRACE 700 has become the industry standard for HVAC system design as well as energy and economic analysis over the past 20 plus years.  The TRACE 700 family of products are in the process of being sunset as customers migrate to the updated technology platform TRACE 3D Plus.
