[Radiance-general] Louvered skylights simulation

[Christoph Reinhart]

-          Is DIVA-for-Rhino better than Daysim for this? On the website I read that Daysim is capable to interface with other software in order to perform, for example, thermal simulations. Is this right?
Diva-for-Rhino is a plug-in for Rhino that runs Radiance/Daysim and E+ in the background.


-          Is there any radiance/python script already available to study/learn from?

Maybe some of the others have something?

Dear Christoph,

Thanks for replying so quickly.
Two questions about what you wrote and before I delve into studying all the necessary programming:


Thanks, regards

Dear Stefano,

I had similar projects in the past in our daylighting class where students modeled the annual performance of a tracking heliostat by modeling a discrete number of mirror settings in Daysim/Radiance and then assembled an annual *ill file using a script. In your case I probably would use DIVA-for-Rhino in combination with some Python scripting.

Best,

Christoph

Hi,

I'm a Master student in Mechanical Engineering, and I'm working in California at UC Davis CLTC to complete my Master Thesis on lighting energy efficiency and daylighting.
I'm interested in daylighting simulation, and I found the following pages online giving some insights about the topic:

http://www.radiance-online.org/pipermail/radiance-general/2007-November/004577.html

I was particularly interested by the latter article, since it refers to something quite similar to what I would like to do: I want to simulate the behavior of controlled louvered skylights to get the luminance maps of the a space, possibly reproducing their motion (or, otherwise, manually setting the behavior at different angles).
I've no experience with lighting simulations environments.. could you give me a couple of suggestions? My questions are:


-          Is Radiance the best simulation tool available for the object I want to simulate?

-          How would you conceptually implement a louvered skylights with motion?

Thanks for your attention,
and Best Regards
