Avoiding daylight avoidance
Measures stimulating daylighting may not lead to avoidance of daylight and thus become counter-productive.
Architectural spaces (light and sight)
sensory oversensitivity to light
In order to
promote concentration and teamwork in school and possibly lessen sleep problems.
This recommendation is one of three mutually dependent recommendations in the chapter ‘architectural spaces’.
As explained in the theme ‘light and sight’, a balance has to be struck between sufficient incoming daylight and the tendency of many people on the spectrum to avoid it. This avoidance can have several detrimental effects; here we add the hypothesis that sleep problems may be part of these.
Daylight therefore should not be direct or overabundant.
There are many ways of achieving this, such as with the aid of lace curtains and other means of interior design. In this case of building or refurbishing one can think of:
- sandblasted glass (see Humphreys)
- clerestory glazing (Beaver, 2004 and Humphreys)
- sloping ceilings for optimal reflection.
The textbook example of clerestory glazing are the windows in the uppermost part of the nave of a basilica which rises above the lower aisles. The incoming light through such windows is tempered. Humphreys shows a picture of it. Beaver (2004) uses this principle repeatedly and illustrates it with drawings.
In the theme ‘light and sight’ a hypothesis is presented about daylight avoidance as a possible contributing factor to sleep problems. If this idea is correct, the measures in this recommendation also serve to alleviate sleep problems.
An extra measure in this context is the application of glass which selectively allows the part of the light spectrum (the short-wave blue-green part) which hinders the release of melatonin. Evidently, this measure contributes to an undisturbed production and release of melatonin.
