<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>Hi all, I&#8217;m doing some glare calculations for
the first time and am in general new to Radiance. I&#8217;m trying to work out
how to take account of the ambient lighting level within a room when I&#8217;m
performing a glare calc for daylighting? Is it using the &#8211;av setting, and
if so, how do I convert the internal light level of 400lux into a &#8211;av setting?
Thanks, Erik<o:p></o:p></span></font></p>
