<\/span><\/div>

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

When we talk about natural lighting, the lighting requirement is expressed in terms of “daylight factor<\/strong>” (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<\/strong> entering buildings.<\/p>\n<\/div>

<\/div><\/div>

300<\/strong> lux, 50%<\/strong> of the time,
\nover 95%<\/strong> of the surface<\/p>\n<\/div>

This is the minimum threshold recommended by European standard EN17037 <\/strong>“Daylighting of buildings”.<\/p>\n<\/div><\/div><\/div>

Benefits & advantages<\/h2><\/div><\/div><\/div>
<\/span><\/div>

Health<\/h3><\/div><\/div><\/div><\/div>

Natural light = well-being and good health.<\/strong><\/p>\n

Natural light stimulates the production of hormones that affect concentration, mood, learning, attention <\/strong>and sleep.<\/strong><\/p>\n

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.).<\/p>\n<\/div><\/div><\/div>

<\/span><\/div>

Economical<\/h3><\/div><\/div><\/div><\/div>

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%.<\/strong><\/p>\n<\/div><\/div><\/div>

<\/span><\/div>

Security<\/h3><\/div><\/div><\/div><\/div>

-50% reduction in workplace accidents.<\/strong><\/p>\n

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

<\/span><\/div>

Environment<\/h3><\/div><\/div><\/div><\/div>

More natural light means less artificial lighting. This optimised management of lighting reduces<\/strong> a building’s energy costs<\/strong>.<\/p>\n<\/div><\/div><\/div>

<\/span><\/div>

Aesthetics<\/h3><\/div><\/div><\/div><\/div>

It’s no secret that natural light enhances a building’s volumes<\/strong>, design and architecture.<\/p>\n

Natural lighting is an element of the d\u00e9cor and brings visual and physiological well-being to occupants.<\/p>\n<\/div><\/div><\/div>

<\/span><\/div>

Productivity<\/h3><\/div><\/div><\/div><\/div>

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.<\/strong><\/p>\n

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

Renovation : How can thermal insulation and staff comfort be improved ?<\/h2><\/div>

Our case study on natural light<\/strong> concerns the renovation of a technical building. Located in the Moselle d\u00e9partement, it houses the mechanical workshop and vehicle repair and maintenance shop for the d\u00e9partement’s technical services.<\/p>\n

The project involves the complete renovation of the roof<\/strong>, with the aim of improving thermal insulation and staff comfort<\/strong>. In addition, the client specifically wanted the roof to be floodedwith natural light<\/strong>.<\/p>\n<\/div>
