Engineering rationale

Why We Built These Tools

During hundreds of building performance simulation projects we observed that engineers spend a significant amount of time processing simulation outputs instead of interpreting results.

These engineering tools automate repetitive post-processing tasks while leaving engineering judgement entirely in the hands of qualified professionals.

The objective is simple:
  • Reduce repetitive work
  • Improve consistency
  • Save engineering hours
  • Standardize deliverables
Engineering productivity

CHAAC Plan2Model

AI-assisted pipeline that converts architectural plans (PDF / CAD) into validated building geometry. AI interprets drawing intent while deterministic code enforces geometric truth — calibration, snapping and topology checks — producing simulation-ready gbXML and DXF output.
