Hi,

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.

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).
But there is no effect on the lighting energy. This is the same if I use a
skylight (aka a light well).

Has anyone used this successully?

thanks
Norm
