WHY IT EXISTS

Why This Tool Exists

The Problem

AEC teams manually recreate building models when transferring from design tools like Revit to energy analysis software, wasting weeks of work and introducing errors. Each software platform uses proprietary formats, creating data silos.

The Solution

Provides a standardized XML schema with over 500 elements that automates building data transfer between BIM and analysis tools. Single export from Revit creates files readable by 50+ engineering applications.
