[TRNSYS-users] daylight in offices

[David Bradley]

Dear Ruut,
   I did a TRNSYS study some years ago that included a daylighting aspect. 
We were looking at the usual ability to step back electric lights based 
upon the amount of available daylight on a particular work surface. While 
there was not a particular Type that I was able to use, I found a lot of 
good information in a Master's Thesis done at the Solar Energy Lab in 1996 
by Jim Kelsey. You can download the thesis online from 
http://sel.me.wisc.edu/publications/theses/theses2.html. I hope that helps.
