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.

Sefaira is cloud-based building performance analysis software for architects and designers using SketchUp or Revit. It runs annual energy, daylight, thermal comfort and HVAC sizing simulations powered by EnergyPlus and Radiance directly from a conceptual model. Built for early-stage design decisions, it turns full-building simulations around in minutes instead of weeks.
Ladybug Tools is a free, open-source suite of environmental design plugins for Rhino and Grasshopper. It connects 3D CAD models to validated simulation engines like EnergyPlus, Radiance, and OpenFOAM. Architects, engineers, and students use it for daylighting, energy, comfort, and airflow analysis inside their design workflow.
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.
