Calculate DF% per area

Hello guys,

I was wondering if it is possible to calculate the area of a space (e.g. a room) that conforms with a minimum daylight factor.

I have done a simple daylight simulation, much like the one Mostapha shows in his example of parametric daylight analysis, but apart from visualizing the result grid for every case I would like to calculate the area that is below the minimum Illuminance selected in the legend parameters of the recolour mesh.

Any ideas how I could do that?

Thank you in advance!

Kind regards,

Theodore.

Hi Theodore,

I would try to turn the mesh into a Brep and calculate the surface this way. I am attaching a .gh definition I found in here (unfortunately don't remember who made it to credit). Could you update if this works? 

Thanks,

Tasos

Another option is to use Cull Face. Check the attached file for an example:
