[Radiance-general] radmap (on windows)

[Nick Doylend]

I just gave up trying to get it to run on Windows, even running without
any temporary files left hanging around it still generated a bunch of
zero length composite sky files and failed.

I had more luck running under Linux, and it seemed to do its thing much
faster.  However, I'm not sure how to interpret the results!  To test I
created a flat ground plane and looked at the cumulative map - the
results were about 822kWh/m2.yr when I traced points on the original kWh
image and approximately the same in the false coloured kWh image.  If I
looked at the source EPW data I found a cumulative global horizontal
radiation to be more like in the region of  1200kWh/m2.yr.  Shouldn't
they be the same (assuming I set lat/lon/mer correctly)?

The MJ scaled image didn't make much sense - I thought that 1kWh is
3.6MJ, but I get a much lower result when I look at MJ than kWh.

Are there any papers describing the program in more detail (I've looked
only briefly at the man page and a .pdf presentation so I'm probably
missing something)?

Thanks,

Nick
