[Radiance-general] Annual daylight simulations

[Marija Velickovic]

Hi,

I read Greg's presentation from the Workshop related to annual daylight
calculations with rtcontrib and few additional tools.
Greg, I'm interested if this method is still in research and validation
phase or it can already be used in calculations.

Generally, I've understood most of the calculation steps, and found in the
HEAD release Perl scripts for additional tools you mentioned in the
presentation.
Question is how to calculate Transmission matrix with BTDF values for the
specific window or group of windows?
I see it should be some file in xml format, but not sure how to create it
when classic transmittance and reflectance data are known for the glazing;
and also what format if has.
Also for non-complex glazing systems (like double or triple glazings,
without internal blinds and similar), is it possible to compose this BTDF
matrix "manually"?

####
Does someone on the list already performed annual calculations, with this or
some other method, with rtcotrib program?

Thanks,
Marija
