Question

_________ roofs have vertical roof glass facing away from the equator side of the building to capture diffused light (not harsh direct equator-side solar gain).

(a) Clerestory

(b) Sawtooth

(c) Translucent

(d) Curved

This question was posed to me by my college director while I was bunking the class.

Question is from Orientation of Building and House Planning in section Planning of Building and Colony of Civil Engineering Drawing

Answer 1

Correct option is (b) Sawtooth

For explanation I would say: The angled portion of the glass-support structure is opaque and well insulated with a cool roof and radiant barrier. The sawtooth roof’s lighting concept partially reduces the summer “solar furnace” skylight problem, but still allows warm interior air to rise and touch the exterior roof glass in the cold winter, with significant undesirable heat transfer.
