[Radiance-general] GenCumulativeSky - problem of reading .epw file

[Reinhart, Christoph]

Dear Kam,

 

This posting might be better suited for the DIVA-for-Rhino forum
(http://groups.google.com/group/diva-for-rhino) but maybe
GenCumulativeSky is also of interest to some on the general Radiance
list. The program was written by Darren Robinson and generated a
cumulative sky for annual or monthly radiation maps . There are similar
methods available by Francesco Anselmo and John Mardaljevic.

 

The program is started with:

 

GenCumulativeSky +s1 -a 45 -o 76 -m 75 -r -E -time 0 24 -date 1 1 12 31
epw_file > Gund_111.cal

 

You could try to debug your epw file from Singapore using the command
line. We are actually working on a project in Singapore right now and
the local file worked for us.

 

Christoph

Dear all, 

 

I have tried to use the GenCumulativeSky.exe programme made available
through Diva for Rhino v1.1f.  

 

When I ran the programme on a DOS command line, it said:

 

**

Error opening: SGP_Singapore.486980_IWEC.epw

GenCumulativeSky: Error reading climate file
SGP_Singapore.486980_IWEC.epw

**

 

I tried it with the San Francisco .epw file as well but it also didn't
work. 

 

Could anyone advise how it can be solved?

 

Also, may I know what it means by "hourshift" in the -h entry?  

 

Thanks a lot!

 

Cheers, 

Kam
