clerestory
A window or set of windows located high
in a wall near the eaves, or in a roof, that allows daylight into a building
interior, and may be used for ventilation, light, and solar heat gain. The
windows are typically operable windows and best oriented either south or
north. A south-facing clerestory requires adequate roof
overhang to prevent direct solar
gain. Operable windows in the clerestory also allow heat to escape from
the house during the cooling season. North-facing clerestories may require
a vertical wall section on the exterior west side to prevent heat gain from
the setting summer sun.
A clerestory is an element in passive
building design and, in particular, passive
solar design.
In church architecture, a clerestory is a row windows in an upper story
of a nave, particularly above the roof level of any aisles along the sides
of the nave. Related categories
