well i'm thinking it's the former ... i was very careful about making 
sure the media container enclosed the building.

box { <-21, -0.1, -21>, <21, 10, 21>
   pigment { rgbt 1 } hollow on finish { diffuse 0 }
   interior {
     media {
       scattering { 3, 0.00275 }
       samples 32, 64
       intervals 1
       method 3
       }
