Daylight Visualizer is a software tool dedicated to daylighting design and analysis. It simulates daylight transport in buildings to aid professionals by predicting and documenting daylight levels and appearance of a space prior to realisation of the building design.

You can import 3D models in DWG, DXF, SKP and OBJ. It provides accurate daylight factor, illuminance and luminance levels and covers all glazing elements from windows and glass doors to skylights and glass operation panels.
