How to get hourly illuminance result of direct beam sunlight?

Hi, community!

May I know if there is any way to get the hourly illuminance result for direct beam sunlight?
I found that the HB annual daylight results folder including “direct” folder, but not sure how to have it in grasshopper environment.
Thank you!

Hi @gogog,

Do you want the hourly illuminace for a sensor, e.g., by using HB Annual Results to Data?

Hi, @mikkel

Yes, I want the hourly results for direct sunlight only, I need it to generate the interior shade schedule (more than 2% of sensors have >1000lux according to LM83).
I tried to use HB annual results to data, but it only can get the total illuminance.

Hi @gogog,

The option to switch between total and direct results is not exposed in Grasshopper, but it exists in the core libraries. In the attached Grasshopper file I have added the option to the component.

annual_daylight_hourly_direct.gh (96.7 KB)

In case you don’t know, we also have a recipe for LEED Daylight Option I, which is free to use for local runs through the Pollination Grasshopper Plugin. The recipe creates shading schedules for each aperture group in the model.
