Point-in-Time Illuminance

This workflow supports the calculation of illuminance distributions for electric lighting and/or daylight at specific moments in time.

The workflow relies on five subpanels:

If you have not done any lighting simulations in ClimateStudio, it is recommended that you initially go through the Lighting Model Setup video tutorial (5 minutes). The Rhino file used in the tutorial is available for download.

Once all required input subpanels have been populated, a simulation is invoked by pressing the start button.

ClimateStudio uses a progressive path-tracing version of the Radiance raytracer to simulate illuminance distributions. While a simulation is in progress, new iterations are added to the simulation results until the user-specified number of passes has been reached. Details on the simulation settings can be found in the Path-tracing Settings Subpanel.

Simulation Results

Upon completion of the first pass, the simulation automatically switches into the ClimateStudio results panel. An overview of the results panel is provided here. The image below shows the point-in-time illuminance results panel with an illuminance distribution shown in the Rhino viewport to the left and overall statistics (mean and median illuminances) displayed on the right. The Rhino viewport results can be modified using the Viewport Display editor.
