Hi

I have two questions:

- is it possible to increase the accuracy of the daylight autonomy calculation? The results in the DA-file are integers and give % per year. When recalculating to hours/year, I am only +/- 40-50 hours accurate (0.5*8760/100).

- is there a way to visualize the sun position with Diva for Rhino (no Grashopper)? The goal is to check the location of light patches due to directly transmitted sunlight (no reflections).

Thanks!

Hi Sarah,

1. Directly from Daysim, there isn't as far as I know although your hour inaccuracy will be less than that, since all 8760 hours of the year aren't occupied.

2. Beyond the Grasshopper tool, in DIVA-Rhino all you can do is to run a rendering with 0 ambient bounces. This will only calculate the direct sunlight.'

Best,

Alstan

Hi Alstan

As a (late)  feedback to point 1: the study concerns the daylight exposure of art works, which are present 24/7. I adapted the schedule to the actual daylight hours, but am still limited to an accuracy of +/- 25 hours. It seems silly to be dependend on this output, as it is probably calculated more accurately? Maybe there has been an update in the mean time?

Thanks

Further question: a daylight autonomy of 0 % equals 0 % or < 0.5 %?

I would really appreciate a quick feedback on this, as it is very important for our client!

Thanks

Sarah
