light bulbs sketched on chalkboard Many small ideas make a big one

Today it is impossible to work inside, and often even outside our buildings, without the light from lamps. 90% of human activity is dependent on vision: assuring an efficient lighting to your workforce is therefore essential.

Lighting can account for up to 15% of your company's energy consumption. However, it is possible to reduce your expenses while maintaining a sufficient quality lighting.

It is mainly a matter of equipment:

- Bulbs:
Use recent lamps that have a lower power rating for the same amount of light (such as compact fluorescent lamps, LED lamps, etc). They are more economical and more efficient.

- Presence/absence/movement detectors:
Install them in areas that do not require permanent lighting (corridors, stairs, warehouses, archives, toilets, technical rooms, etc), while of course complying with safety lighting standards. They make it possible to eliminate unnecessary lighting.

- Light sensors:
They enable artificial lighting to be regulated according to the intensity of natural light.

- Switches:
Always place them visibly at all access and exit points to allow all your employees to use them.

It's also, of course, a matter of behaviour:

Our tips and tricks:

- I dust off regularly all the lighting for a better luminosity
- I turn off the lights when I leave a room
- I make the most of natural light by placing my desk by the window and opening the blinds
- I use light colors to paint the walls and ceilings
- I'm banning halogen lamps
- I avoid decorative lighting as much as possible

With these simple gestures that only challenge a few habits, you can save money and make your business more environmentally friendly.

It is essential to motivate and involve all your employees.

Some key figures:

- Good lighting management can save up to 7.5 euros/m2/year
- 24% savings by installing presence/absence detectors
- Dust can reduce the brightness of a light bulb by 40%
- Low-energy light bulbs consume 4 to 5 times less electricity and last on average 6 times longer
- Dark tints on the walls lead to a doubling or even tripling of lighting intensity
