Here is one which uses realistic energies for sun and sky.
The net diffuse value for concrete is realistic 0.4.

Same method applied to a model where the materials of the
outside structures were at some random default values resulting
from multiple conversions. The inside materials were ok (net diffuse
0.25 for sandstone) so it's mostly realistic.

Very high quality radiosity was used in the first scene because
measurements from the color probes needed to be accurate. Lower
quality settings give faster but less accurate results. It's still
going to be slow and difficult to use. If interested mail me.
