was thinking exactly along the lines of Nick – if you have a plenum you need to
create a dummy roof to house you light tube. Just another thing to add – the
wall that you host this light tube on is going to behave like it was a roof to
the space (in terms of conductance) so you probably want to create a material
that makes it close to adiabatic (high R-value material)<o:p></o:p></SPAN></P>

extra thought: Don’t count on daylight moving between/across spaces…

the light will only be measurable in the plenum for daylighting control

approach for detailed mode that may be instructive for core spaces remote from
the exterior: If your core space does not already have an exterior surface
defined, you will want to create one to host the window. It could be a
wall/roof… don’t think it really matters. Play with this exterior
surface’s location/dimensions/orientation until it is situated above and
parallel to your roof surface above, then create a window within this remote
exterior surface. Light should then “jump” to the core space, bypassing
any plenums or other spaces along the way.<o:p></o:p></SPAN></P>

create a window in the roof, change the window to "Tubular Daylighting device"
