[Radiance-general] Cumulative calculations of irradiance

[Iván Pajares Sánchez]

Hello group,

I am working out some simulations to get some figures that help me 
estimate irradiance on a building for thermal load comparison. What I am 
trying to do is to gauge the range of numbers one can get and the 
differences in different part of the building so I have a basis to speak 
to the engineer.

To do this I generate my Radiance model with only one material to start 
with with 50% reflectance. I generate a 1/2 hour series of renderings 
(with -i switch on).
Afterwards I add up the irradiances with pcomb to get one picture from 
which to get the falsecolor scale in kWh / m2.

I'm using falsecolor with -m = 0.001 to get the output in kWh / m2 to 
get daily cumulative irradiances. Is this approach correct?

I'm doing this because RADMAP for windows fails to work (even the 
example files that come with it) so I wanted to play around with 
radiance and learn something on the way.


I guess my next step is to feed real irradiance data into radiance and 
foloow the procedure outlined before, Am I in the proper direction?

Thanks for any feedback!
