evalglare

I ran evalglare and found a VCP of 307 and a UGR of 26. According to p. 3-31 in the IESNA handbook, a UGR of 26 corresponds to a VCP of <=40.

VCP = Visual Comfort Probability = bound between 0 and 100%. Can you please check your VCP calculation/algorithm?

Thanks

Martin

Hi Martin,

oh yes, there seems to be an error in the calculation of the VCP.
I have to admid, that I have used evalglare only for daylight situations yet. So I've used only DGI, CGI and DGP yet, although I've implemented other indicees, too.
As soon as I return from my ski holidays (in about a week), I'll check that.
