Context

The Mercure Hotel in Courbevoie (18,600 m², 11 floors) was looking for quick cost savings without using its own budget. The two levers chosen—BMS optimization and complete relamping—are those that offer the best return on investment in the hotel industry.

The first results were visible within the first few weeks. No disruption for the teams, no impact on the customer experience — and a structural reduction in operating costs.
