2016-02-23 19:35:15 -0500	answered a question	Can radiance calculate the DGI ? Evalglare (see the PDF at http://www.radiance-online.org/learni...) calculates DGI, as well as several other daylight metrics, and it is now part of the NREL Radiance distribution. If you're using it as a design tool as well as to satisfy Chinese code requirements, I recommend looking at DGP.
2016-02-22 19:23:13 -0500	commented answer	Rendering With Radiance On the other hand, the awk book is still $100. No wonder hardly anyone uses awk any more.

2016-02-22 11:25:02 -0500	answered a question	Rendering With Radiance Thanks, Rob. I'm still not sure that anyone is actually paying those several hundred dollar prices; I think they're computers bidding against computers.
2015-12-30 11:56:28 -0500	commented answer	The Definition of Radiance Parameters in OpenStudio I have copies for US$35 + shipping + handling. I ship globally. I also have a few misprints (the printer left out the Greek letters, trashing much of the math, but you can still learn how to run a simulation from them) that I am remaindering for US$12 each, including shipping, within the USA. (It's just not worth shipping those internationally.) Truth in marketing: there will eventually be a free PDF (sometime, I am determined, in 2016), but don't hold your breath.
