Clerestory
windows:-
´Another
important element in creating daylighting is the use of clerestory windows.
´These are
high, vertically placed windows. They can be used to increase direct solar gain
when oriented towards the equator.
´When facing
toward the sun, clerestories and other windows may admit unacceptable glare. In
the case of a passive solar house, clerestories may provide a direct light path
to polar-side (north in the northern hemisphere; south in the southern
hemisphere) rooms that otherwise
would not be illuminated.
´Clerestories can be used to admit diffuse daylight (from the north
in the northern hemisphere) that evenly illuminates a space such as a classroom
or office.
Clerestory windows also shine onto interior wall surfaces painted
white or another light color. These walls are placed so as to reflect indirect
light to interior areas where it is needed. This method has the advantage of
reducing the directionality of light to make it softer and more diffuse, reducing shadows
