Well-designed daylighting features can deliver
many benefits to the home, such as high light
levels, potential for energy savings, a view and
connection to the outdoors, and light wavelengths
that help maintain human circadian rhythms and
immune system health.

Shapes
!
Skylights come in many shapes, with rectangles, circles,
ovals, diamonds, triangles, multi-sided and tubular
being most common.
!
This skylight option minimizes heat gain during the day
and heat loss during the night but does not offer a view
or ventilation.

Skylight size
!
The size of the skylight is directly related to daylight
levels and solar heat gain. The DOE suggests a rule of
thumb that the skylight should not be more than 5% of
the floor area in rooms with many windows and no
more than 15% in rooms with few windows.

Orientation
!
Skylights on north-facing roofs
provide relatively constant
illumination with a cool light
appearance, while skylights on
south-facing roofs provide
constant, high illumination
levels and the greatest potential
for heat gain.

Ventilation
!
Some skylights offer the ability to ventilate hot air that
gathers near the ceiling. The skylight may open manually
or automatically.
