Are tubular skylights / Solatubes thermal chimneys in a house?
My house design has a long E-W axis in order to exploit Southern exposure and this creates a middle of the house, mostly hallways/foyer, which have no window exposure.
A solotube piping some natural lights into these dark areas would be terrific, but what I don’t want to create is an attic with r-80 coverage and have most of the heat in the conditioned space bee-lining for the “weak spot” under the solatubes and then race up these chimneys.
Are there any energy efficiency tricks in the grab bag of methods used by Green builders to bring light into dark areas of the house?
Any skylights which can transit through an attic and open up to a 2nd floor living space or extend further and open into a first floor space?
