color=#0000ff size=2>I have never had success at getting daylighting to work
without exterior glazing on a wall. Interior glazing and skylights alone
will not work. DOE2 engines require some exterior walled glazing. I would
recommend that you create the zone in a separate file, determine the T-vis and
SHGC change through two layers of glazing on the wall and add your skylights.
I'm not clear if DOE2 will model the daylighting effect of skylights well or if
it will just take the daylight energy savings from the wall. I was modeling
SolaTubes the other day in a zone with exterior walled glazing and it
didn't seem to provide much savings, a lot less than I would have
expected. Anyone else have any thoughts on this?</FONT></SPAN></DIV>

4-story internal atrium with skylights on the roof. There are some
interior rooms with interior windows facing the atrium, and I have enabled
daylighting for these rooms. When I run the simulation I get errors for
all of the rooms with only interior windows saying that the window area must be
greater than 0.1 ft2 for the room. The windows are much larger than
that. Has anyone else run into this kind of problem? Any
thoughts?<o:p></o:p></SPAN></FONT></P>
