Daylight Study Overview

Daylight Studies are calculated to understand the progression and intrusion of daylight into an environment over some defined time interval or at critical dates and times during the year, such as at solstices and equinoxes.

Depending on the number of samples requested, Daylight Studies can take significant amounts of time to calculate.

A Daylight Study can give you the following results:

  1. Visualizations: RGB, Grayscale and Pseudocolor images can be generated from each daylight analysis pass. To see multiple images for each date and time, create multiple Render views in Render Mode and specify the Viewpoint you'd like to use. Radiosity renderings and/or Ray Tracing images may be generated.
  2. Illuminance and/or Daylight Factor calculations: To see the calculated point-by-point values for each daylight analysis pass, save the AGi32 job files for each date and time. The General tab includes a check box allowing for this selection. Once the Daylight Study is complete, you may open each job file and view the calculated results.
  3. Interactive Renderings: By saving the Radiosity Solution files (RSF files) in addition to the AGi32 job files, you may see the completed rendering for each daylight analysis pass and navigate inside or around your environment without having to recalculate. Depending on the project, RSF files can be quite large and take time to save. Enabling this switch requires that you have plenty of disk space and time.
  4. Saving Studies: You can save studies within one job file, each with different study settings and Date/Time Samples. Study settings for each Study Name are automatically saved (when you click OK), and can be recalled via the Study Name drop-down list.
