Because artificial lighting accounts for a growing proportion of our energy consumption, we have made natural light the cornerstone of our thinking. The skylight (taking into account the light transmission of the infill) therefore becomes an asset for diffusing natural light.

When we talk about natural lighting, the lighting requirement is expressed in terms of “daylight factor” (DFL). This is also the indicator most commonly used in environmental quality initiatives. The daylight factor is a value that makes it possible to precisely quantify the amount of natural light entering buildings.

300 lux, 50% of the time,
over 95% of the surface

This is the minimum threshold recommended by European standard EN17037 “Daylighting of buildings”.

Installing our products on roofs or facades optimises the amount of natural light in the building and reduces its primary energy consumption (Cep) (see Th-U and Th-L rules).

Benefits & advantages

Health

Natural light = well-being and good health.

Natural light stimulates the production of hormones that affect concentration, mood, learning, attention and sleep.

The absence or lack of light has a negative impact on the internal clock and the biological cycle, which can lead to a deterioration in health (depression/insomnia/digestive problems/mood swings/stress, etc.).

Economical

More natural light, less energy consumption – it’s easy! Installing skylights, for example, can reduce the time spent using artificial lighting by 30 to 50%.

Security

-50% reduction in workplace accidents.

Good natural lighting makes it easier to concentrate and carry out sometimes difficult tasks. It reduces fatigue, one of the main causes of accidents in the workplace. Going from 500 lux to 2000 lux at a workstation means 50% fewer accidents (German study).

Environment

More natural light means less artificial lighting. This optimised management of lighting reduces a building’s energy costs.

Aesthetics

It’s no secret that natural light enhances a building’s volumes, design and architecture.

Natural lighting is an element of the décor and brings visual and physiological well-being to occupants.

Productivity

Several studies have shown that natural light promotes learning and productivity. In schools, as in the workplace, learning and the performance of tasks are more efficient…. and absenteeism is reduced.

An increase in efficiency of 3 to 6% has been observed with the addition of natural light. In sales areas, the increase in purchases is considerable +28% compared to an environment without natural light.

Renovation : How can thermal insulation and staff comfort be improved ?

Our case study on natural light concerns the renovation of a technical building. Located in the Moselle département, it houses the mechanical workshop and vehicle repair and maintenance shop for the département’s technical services.

The project involves the complete renovation of the roof, with the aim of improving thermal insulation and staff comfort. In addition, the client specifically wanted the roof to be floodedwith natural light.
