Incoming sunlight (large windows)

Recommendation 77
Position windows strategically against prolonged, bright and / or low sun

Chapter (theme)
Architectural spaces (light and sight)

Because of
sensory oversensitivity to light

In order to
avoid exposure to direct and indirect sunlight when it is experienced as unbearable.

This recommendation about sunlight is directly related to recommendation 79 about penetration of daylight and 80 about the avoidance of too much natural light.
As usual, in the case of independent living there is more room to accommodate individual preferences than in the case of housing groups and families. Here one can determine case by case what is desirable and what is not.

In all cases the dilemma has to be solved that natural light can generally be viewed as very beneficial, while many on the spectrum suffer enormously from direct and indirect (i.e. reflected) sunlight. Assuming the home still has to be built, this can be achieved through high-level or clerestory glazing and – conversely – by avoiding building large glass surfaces and/or reflective materials in walls, floors and furniture. Avoiding solar gain should also be a concern.
Furthermore glass properties should be taken into consideration among which its sunlight permeability.

Additionally, in homes which already have large glass windows, blinds may be considered, which should be silent instead of rustling or flapping.

Windows facing the sun are not problematical under all conditions, such as when trees obstruct incoming sunlight.
