Clerestory

A high window that admits daylight from the side.

Upper nave windows and high factory or gallery windows bring light deep into a room while preserving privacy and limiting direct sun.

Modernists including Le Corbusier and Kahn used clerestories to shape space with light. Glazing and shading choices govern glare and heat.

The Kimbell’s light slots and upper windows in basilican churches belong to the clerestory family.
