Introduction
In school buildings, there is a need for sufficient daylighting in teaching areas for both comfort and energy savings purpose.
It is of particular importance that the problems of glare and summer overheating can be analysed at the same time.
Indeed, if the luminance of the sky seen through a window is very high compared to that of visual task, disability glare can result in a reduced performance.
Discomfort due to high luminance contrast is most likely to happen and should be treated with special devices attached to the window design.
As a result, ideal solar control systems should reduce solar radiation whilst admitting diffuse radiation as daylight and allowing outside view.
In this context, we will not deal with bioclimatic buildings e.g. solar collection or stocking, but only with especially shading systems and glare protections, and solar control systems.
Also, the design of the openings will not be discussed any more as a solar control technique although it is certainly the first step to avoid summer discomfort and visual glare in the designing process.
