WHY IT EXISTS

Why This Tool Exists

The Problem

Lighting designers manually compute illuminance values outside Revit using external tools like AGi32, requiring export of geometry, external calculations, and manual reconciliation with design drawings. This workflow adds 4-8 hours per project and breaks the BIM design process, increasing errors and design iteration time.

The Solution

ElumTools brings the proven AGi32 radiosity calculation engine directly into Revit as a native add-in. Designers calculate illuminance directly on Revit geometry using lighting families already in the model, eliminating export/import cycles and enabling real-time design feedback with Layout Assistant for automatic fixture placement optimization.
