You won't necessarily need to get rid of the warning.  It's telling you 
that you selected "world coordinates" in your "SurfaceGeometry" object but 
have non-zero origins in the Building and Zone statements.  The Detailed 
Daylighting model uses these non-zero coordinates as you enter the 
reference points for the daylighting in "relative (to building/zone 
origins) coordinates".  The World Coordinate system does not use the 
building/zone origins at all.
