ElumTools is a lighting-calculation add-in built for architects, lighting designers, and MEP engineers working inside Autodesk Revit.
It runs entirely inside Revit's own ribbon, calculating point-by-point illuminance on rooms, spaces, regions, and views using the fixture families and geometry already in the model.
A radiosity-based visualization lets designers walk through and evaluate how light interacts with surfaces before construction.

Insight was Autodesk's building performance analysis toolset for Revit, giving architects and engineers real-time energy, daylighting and load simulation feedback during design. It combined FormIt Pro and Revit BIM workflows with DOE-2.2 and EnergyPlus simulation engines to support sustainability reporting such as the AIA 2030 Commitment. Autodesk retired Insight Energy Analysis and Green Building Studio in 2025 in favor of Insight Carbon Analysis.
ClimateStudio is a Rhino 3D plugin that gives architects, lighting designers and building-performance consultants fast, accurate environmental analysis. It simulates daylighting, glare, electric lighting, thermal and visual comfort, and energy performance in a single workflow, with a Revit exporter for daylight models.
pyRevit is a free, open-source Rapid Application Development environment for Autodesk Revit that lets architects, engineers and BIM developers build automation tools and add-ins using Python, C# or VB.NET. It ships with a ready-made toolset, a CLI for deployment, and a telemetry server for monitoring usage across teams.
