Dear list,
I wonder if anybody can kindly help to provide a *step-by-step guidance on
how to use Radiance to conduct daylight coefficient based "climate-based
daylight metrics" *such as Daylight Autonomy, Daylight Availability,
Continuous Daylight Autonomy or Useful Daylight Illuminance.
I know that there are several papers explaining the concept and process,
and DIVA-for-Rhino is the tool for this. But I just wan to understand *each
step of the calculation under the hood*.
I want to digest *a breakdown of the process, *maybe in the form of a shell
script file (Unix) or batch file (Windows), which explains each of the key
steps and the Radiance programs and respective parameters used, such as how
daylight coefficient of a given sensor is calculated and by which Radiance
program, when the gendaymtx and rcontrib are used and what are their
functions, and what is generated in each step and how it is used in later
steps, etc.
I have a simple scene prepared describing a simple room with south facing
window and some shading blinds. The scene file, material file and sensor
file are shared in the following link:

I hope you can give me some guidances using this simple example!
Thank you!

Hi David,
I am copying this email to the Radiance-Daysim list as well. There are two more streamlined ways to go about this right now: using Daysim or using the Radiance three or five-phase methods.
For using Daysim, there is a lot of information I can provide:
- Tutorial from NRCAN: http://archive.nrc-cnrc.gc.ca/obj/irc/doc/daysim-tutorial (slightly updated by Harvard)
- Daysim Documentation page: http://daysim.ning.com/
- A presentation I gave in 2012 on Daysim: http://www.radiance-online.org/community/workshops/2012-copenhagen/Day1/Jakubiec/jakubiec,reinhart_radiance-workshop-presentation_daysim.pdf
If you are using DIVA on Windows, there are Daysim batch files you can open from the c:\DIVA\Temp\RhinoFileName\ folder after running a simulation in order to see how the programs are called.
For the 3/5-phase methods, I am no expert, but a good place to start is here,
Others on the mailing list are highly expert in this.
Best,
Alstan

You can start with these two links:
3-Phase-Method:
5-Phase-Method:
Both are written by Andy McNeil who also gives regular comments on
5-phase-method related questions on the mailing list. It's worth to check
the mailing list archives for his posts.
Regards,
Thomas
