Energy Reduction & Lighting Management: What Real Gains?

Reducing energy consumption has become a central objective for businesses and communities. But what does this reduction actually mean when it comes to lighting? What are the key figures needed to measure the impact of a modernization project? Too often, we talk about energy performance without any tangible data. That's why, today, we're highlighting the energy challenges of lighting through a few key figures.

Lighting: an often underestimated consumption item

Lighting accounts for a significant portion of building energy consumption. Here are some estimates by sector:

Offices: approximately 20% of a building's total consumption.
Logistics / warehouses: up to 40%.
Parking lots: up to 80% of energy consumption.

These figures show how strategic this position is in an effort to reduce consumption.

A park that is still largely obsolete

Today, nearly 60% of the lighting system in France has not yet migrated to LED technology. However, the transition is accelerating, particularly as a result of:

The gradual end of the production of fluorescent tubes, still present on many sites.
The application of the Tertiary and BACS decrees, which impose a reduction in consumption and the implementation of intelligent management systems.

LED is therefore no longer just an option, but a technical, regulatory and economic necessity.

What are the benefits?

Migration to LED

Simply switching from traditional lighting to LED allows for an average 50% reduction in energy consumption in this area.

Adding smart management

By integrating presence and light sensors, the savings are even more significant:

Offices: up to 40% additional savings.
Logistics: around 60%.
Parking: up to 80%.

These figures vary depending on usage, but demonstrate considerable potential for optimization.

Implementation and sizing study

Adapting the power and location of lighting fixtures through a photometric study not only optimizes savings, but also improves the visual comfort of occupants.

Conclusion: Light better to consume less

As you can see, reducing energy consumption related to lighting requires three major levers: switching to LEDs, smart management, and optimizing installation. These combined actions can generate significant savings while meeting regulatory requirements.

Lighting is good. Lighting at the right time, in the right place, and in the right way is even better.
