Clareo, the supplier chosen by AP-HP to modernize the lighting in its hospitals

Hospitals under severe energy constraints, where every lever counts

Hospitals are among the most energy-intensive buildings to operate. Their activity, by its very nature, runs 24/7, encompassing a wide variety of spaces—treatment areas, patient rooms, circulation areas, and technical facilities—all subject to stringent safety, hygiene, and service continuity requirements. Adding to this operational reality is a building stock, often aging, with varying levels of energy performance, making renovation work more challenging, especially since it must be carried out while the building remains occupied and without disrupting medical activity.

In this context, energy costs have become a critical management issue: budgets are under pressure, prices are volatile, and there is a need for multi-year visibility. The recent increase in electricity prices for businesses further underscores the urgent need to take concrete action.

The modernization of infrastructure is thus part of a comprehensive approach which aims to combine energy efficiency, resilience of facilities (reliability, reduction of breakdowns) and quality of use, for the benefit of both patients and teams.

Lighting: a significant factor, and a concrete lever for modernization

Lighting represents a significant energy consumption item in hospitals, accounting for at least 10% of total energy use. This issue is all the more pronounced given that many areas remain illuminated for extended periods, sometimes continuously. Modernizing lighting therefore offers immediate potential for improvement, both in terms of energy efficiency and the daily operations of the facilities.

But lighting is not just a matter of kWh, it is also a lever for quality of life in the hospital.

The objective is to provide lighting that is better suited to its uses, more comfortable for healthcare teams (better visibility, less eye strain, improved working conditions) and more soothing for patients (softer atmospheres, clearer landmarks, more welcoming spaces), while also drastically reducing consumption and, consequently, the electricity bill.

When the perimeter allows, the control system (scenarios, dimming, zone settings) adjusts the lighting to the times of day and needs, and contributes to more reliable and simpler to operate installations.

A public contract between AP-HP and CLAREO to accelerate the modernization of lighting

AP-HP has launched an energy sobriety plan to reduce its carbon footprint and improve the energy efficiency of its buildings and infrastructure, by reducing consumption and accelerating the modernization of equipment.

The contract between AP-HP and CLAREO is part of this dynamic: it aims to accelerate the modernization of lighting across all 38 AP-HP hospitals.

In this context, CLAREO, drawing on its expertise, experience in managing large-scale projects and know-how in deploying solutions adapted to the specific constraints of the hospital sector, will contribute to improving the energy performance of hospital assets.

CLAREO will provide lighting solutions specifically designed for hospital environments, combining hygiene, robustness and performance, including for demanding areas (cleanrooms, laboratories, technical spaces), with resistance to intensive disinfection protocols and high energy efficiency.

For Olivier MASCHINO, President of CLAREO: “At CLAREO, we are proud to work with AP-HP on modernizing the lighting in its hospitals, deploying solutions designed for the constraints of the healthcare sector. Our ambition is twofold: to accelerate the energy transition and to tangibly improve the comfort of staff and the well-being of patients.”
