Sun and Shadow Studies

AKRF’s GIS group specializes in performing shadow studies for environmental impact assessments and siting studies.

We develop digital three-dimensional models, reproduce solar shadows on sample days of the year, analyze shadow impacts on open spaces and other sun-sensitive resources, and create visually striking and intuitive diagrams and supporting documentation.

Our GIS group also produces other 3D-based studies, including solar radiation studies, visual impact assessments, and bulk study visualizations.

The scope of our services includes:

  • Determining extent and duration of shadows from individual structures
  • Visualizing shadow patterns and movement using three-dimensional models
  • Finding the sunniest locations on a site over the course of a day and the year
