Yep.  All the nondirect lighting is from radiosity.  There's only one light 
source and no >0 ambient finishes.

I've been messing around with adding a scattering media but I haven't been 
able to find settings which will produce the sun-shining-through-windows 
effect without either blacking out the skysphere or creating ugly 
artifacts.

Note the *reflections* in the media behind the end pillars (there's no 
glass between the pillars) and the oddities in the shadows cast by the 
cieling grillwork (4th pillar on the right).  Increasing the intervals 
doesn't help.

Here's the media box I used in the attached image.  For scale, the room box 
is 32x16x32 with the world origin at the center of the floor.

box {<1,1,1>*-75 <1,1,1>*75 pigment {rgbf 1} hollow
interior

    {
        scattering {4, (Yellow+White)/200 extinction 1}
        method 3
    }
}}
