Typically, just creating a skylight in an existing roof (which I am guessing is
currently attached to your core plenum space) gives you an error.

and light wells<BR></FONT><BR></DIV>
<DIV></DIV>Hi,<BR><BR>I'm trying to model a light tube and a light well in
eQuest. I'd like to bring light into the core and maybe a lower level and have
this reduce the lighting required.<BR><BR>so, I create a window in the roof,
change the window to "Tubular Daylighting device" and have a daylighting sensor
in the space below (a core zone).<BR>But there is no effect on the lighting
energy. This is the same if I use a skylight (aka a light well).<BR><BR>Has
anyone used this successully?<BR><BR>thanks<BR>Norm<BR><BR><BR></BODY></HTML>
