Hi,
Thanks for the pointers John and Christoph.
I did manage to install DAYSIM and model an office space. When I ran the
simulation I got the 'uncommented lines in the dc file' error which I looked
up in the tutorial and fixed the PATH and RAYPATH environmental variables. I
am using Windows XP on my notebook (the tutorial points these fixes for
Windows 2000, I tried them nevertheless).
I encountered the same error even then. I was trying to fix it and in the
process uninstalled and installed the program 2 to 3 times. Now the program
doesn't start after installation. I can't get it to start despite some
effort. It would help my thesis a lot if I can make it work.
Need your help.
Thanks again,
Ramana.

Subject: [Radiance-general] modeling hourly daylight
illuminance/daylightfactor values for a yearRamana,
A brute-force approach (i.e. a new simulation for every hour) can be
done, but it is computationally very inefficient. A better approach is
to use daylight coefficients. Background, theory and implementation are
described in chapter 6 here:
http://www.iesd.dmu.ac.uk/~jm/zxcv-thesis/
[Web pages seem to be down at the moment - try again later/tomorrow]An end-user DC version called DAYSIM is available from here:
http://irc.nrc-cnrc.gc.ca/ie/lighting/daylight/daysim_e.html
DAYSIM is different in detail from the description noted above, but does
more or less the same thing.-John
