Hallo Andy,
thank you for your reply.
I looked through the Tutorial you advised about. I realised the generated
results are for one day. In our office we are using the .EPW to generate
the results for the whole year. (as used in the tutorial in rtcontrib). Is
it possible with BSDF somehow? if yes, Is there any hints or tips to insert
the .xml format generated by window7beta into the rtcontrib process?
Thanks in advance!

Hi Nasif,
Information for the BSDF material is at the bottom of page 12:
http://radsite.lbl.gov/radiance/refer/refman.pdf
Though I've found that the BSDF material doesn't work well for
daylight coefficient based annual simulations (I'm assuming dds.bash is a
dynamic daylight simulation script). Putting the solar radiance into
skypatches relies on probabilistic sampling to find patches containing the
sun, and if you don't have much direct transmission from the direction of
the sun, you aren't likely to find the sun. Not finding the sun causes big
errors. For now, the three-phase method is a better alternative for annual
simulation of BSDF materials (you can find a tutorial at the bottom of this
page: http://www.radiance-online.org:82/learning/tutorials - if you're at
work, your company's firewall might block access to port 82 - the temporary
location of the new radiance online).

You could try OpenStudio for this; we have a simple implementation of the three phase method currently working with Window6 BSDF files. I'm still working on documentation, but I could help you along offline, if interested.

Hi Nassif,
Data in the BSDF isn't specific to a date or time, so yes it is possible to
do an annual simulation with the xml file from window.
There are two official options and one un-official option:
1 - As Rob mentioned, you can use OpenStudio which does a lot of this for
you.
2 - you can loop through hours of the weather data file. Following is a
bash/awk example (add your weather data file at the end and include -a -o
and -m in the gensky and gendaylit command):
count=-8
while read line ; do
count=$((count+1))
if [ count -gt 0 ] ; then
daytime=`echo $line | awk -F, '{print $2,$3,$4-0.5}'`
alt=`gensky $daytime | awk '{if(NR==3) print $6}'
if [ alt -gt 2 ]; then
dir=`echo $line | awk -F, '{print $14}'`
dif=`echo $line | awk -F, '{print $15}'`
gendaylit $daytime -W $dir $dif | genskyvec | dctimestep V.vmx T.xml D.dmx
output_$count.txt
fi
fi
done < myweather.epw
3 - Unofficial - you can use our annual utility (dctimestepcpu) that takes
a sky matrix file (list of annual sky vectors) and multiplies a whole year
in one go. Let me know if you want to go this route, I can send you the
code for you to compile on your system. This isn't a straight forward
compile process though, it may require some tweaking on your end.

I should have tested BEFORE sending. Here it is again with about 12 errors
fixed...
count=-8
while read line ; do
count=$((count+1))
if [ $count -gt 0 ] ; then
daytime=`echo $line | awk -F, '{print $2,$3,$4-0.5}'`
alt=`gensky $daytime | awk '{if(NR==3) print int($6) }'`
if [ $alt -gt 5 ]; then
dir=`echo $line | awk -F, '{print $15}'`
dif=`echo $line | awk -F, '{print $16}'`
gendaylit $daytime -W $dir $dif | genskyvec | dctimestep V.vmx T.xml D.dmx
