Ahoy! Roof Experts

[George Godwin]

I'm not familiar with the sun-tube either - how would that incorporate?

Chris, - Putting your clients' chandelier element aside for a moment, my thought was that a Belvedere Skylight (Cupola) could be built as an exterior architectural interest item and could just sit on the roof or even house the exterior dome portion of the Sun Tube (Sun Pipe, Sun Tunnel, Sola Tube). But use a Sun Tube to bring light into the area below. There is no heat loss in winter nor heat gain in summer with a Sun Tube and I am sure the Sun Tube would bring in more light to the area below compared to the cupola skylight. Image attached. Any takers? Saves on electricity too.
