Why is Daylight Important?

Daylight is the visual part of the sun and sky radiation. By history of development mankind is adapted to the alteration of daylight, the rhythm of day and night. Its internal clock is reseted by this.

Meteorological events like clouds in front of the sun and fog or precipitation like rain or snow compromise in fact a continuous illumination with a constant illuminance over the whole day.

Illumination an Architectural Impression

But just this dynamic in the play of light and shadow is the big difference to a monotone illumination by artificial lighting, that stimulates us as well. Thus there is no better medium than daylight for the perception of our environment.

Why is a Good Illumination Important?

At first illumination serves the purpose to have sufficient light to fulfill your visual tasks well. A balanced illumination to the work task, the work organisation and the work situation helps to optimize working conditions. The employees in the working environment require sufficient light as well to identify possible risks of danger early and to avoid accidents. More over illumination has an important influence to health and the performance of employees. A good illumination may result in avoiding errors, in preventing early fatigue and in keeping attention up.

Tageslicht steigert Arbeitsproduktivität Daylighting increases work productivity

Sufficient natural daylight improves the conduct of pupils both by increasing concentration and their social behaviour. Sufficient natural daylight especially from above, guided through roof lights into rooms improves according to several American studies significantly the learning efficiency of children in schooling.
Detailed studies in working life also demonstrate that on better illuminated work places appears less fatigue and therefore decreases the error rate rapidly, while the curve of work performance increases steeply upwards.

Multiple Benefits of Individual and Continuous Rooflights

The installation of rooflights as individual or continuous rooflights has a lot of advantages especially for large area buildings:

  • The perched high rooflight openings are available for supply of healthy natural daylight. Daylighting saves energy for illumination of rooms and the dynamic involved produces a good mood for human beings.

  • In combination with openers as ventilation devices rooflights provide fresh air in offices and factory workshops and dissipate used air without energy costs.

  • The installed individual or continuous rooflights can be used as smoke exhaust (Smoke and heat exhaust ventilation system = SHEVS) and for thermal relief (heat exhaust ventilation system = HEVS) in case of fire. SHEVS create a smoke free layer, which enables the self rescue, the third party rescue und a selective fire-fighting method of the fire fighters.
