TYPICAL CONDITIONS

Geographic position, season and weather conditions.
When looking at the effects of natural daylight in offices, the place on earth where an office building is situated is of course one of the key factors. Where an office is situated is of significant importance in terms of natural daylight, hours of sunshine, angle of incidence, intensity of solar radiation etc. It is the latitude of the place on earth where an office building is situated, combined with the effects of the seasons, that determines the maximum height of the sun over the horizon. The height of the sun over the horizon determines the angle of incidence of solar radiation, which in turn has an important impact on the perception of visual discomfort caused by it.

Of course, the luminance of the sky, the illumination of the window and the surroundings and the intensity of the natural daylight also vary according to weather conditions.

A clear sky has a different luminance from an overcast sky, and white clouds illuminated by the sun may cause more glare than direct sunlight.

Fašade Orientation.
A north-facing fašade in the northern hemisphere will not be directly illuminated by the sun. Here, one should try to exploit the benefits of natural daylight to the maximum, as glare problems are minimal. Verosol's transparent fabric types are typically suitable for these facades.

East, west and south facing facades are directly illuminated by the sun to a certain extent, depending on aforementioned variables, such as latitude, season and weather-conditions. Here semi transparent and non transparent materials are usually required in order to provide sufficient protection from glare. At the same time however, they reduce the view to the outside, and therefore impair having a meaningful contact with the world outside. Verosol's day & night blinds are a perfect solution; they combine a transparent and a non transparent fabric in one, fully operable blind.

This enables the occupants of any office to make their own choice as to the optimum compromise between glare reduction and view, depending on all the mentioned parameters.

Buildings opposite the office.
A factor of influence when addressing the issue of visual comfort is the environment of an office building, and more in particular the presence of other buildings in the field of view of the occupant. Such buildings can obstruct the luminance of the sky and/or sun, and therefore reduce the risk of glare.

At the same time however, if buildings opposite the office have mirror-glazed facades, they could increase the risks of glare, even in north-facing offices. The south-facing fašade opposite the office, could in this case reflect the sun and cause very high luminance levels, resulting in blinding or glare.

Note: for countries in the southern hemisphere read north for south and vice versa.
