Which software is listed for Shadow Impact Analysis?

• A. Rhino (with Ladybug/Honeybee) or SketchUp
• B. AutoCAD
• C. Revit
• D. Excel

Answer: (A)

Shadow impact analysis needs tools that simulate sun position and the shadows it creates over time. Rhino with Ladybug/Honeybee provides a robust workflow for this, using Radiance and Daysim to produce accurate shadow maps, daylight metrics, and sun-path visualizations for different dates and times. SketchUp can also perform shadow visualization and, with the right plugins or workflows, support more detailed analyses, making it a common choice for quick or early-stage studies. AutoCAD and Revit are excellent for modeling and BIM, but they don’t offer the same depth of shadow and daylight analysis out of the box as the Rhino/Ladybug/Honeybee setup or an optimized SketchUp workflow. Excel isn’t suited to this type of geometric and environmental analysis.
