As title.

How to involve the redirected solar radiation?
The mirror duct is not affecting heat gain very much since the observation shows that it only gives little daylighting.
The solar piple is really very hot, not only glare but also a feeling of solar radiation.

could you not model it as a room (a tube) with internal emissivity (the solar absorption box represents the emissivity in the visible region) close to 0 to represent a mirror and glass at either end. As i understand it apache should model the reflected light into the room below.
