Case Study: The Marriott Hotel, Frankfurt, Germany

The Marriott Hotel in Frankfurt recently refurbished its 588 rooms to ensure the hotel meets the expectations of today’s guests. New lighting and light control technology delivers significant energy and cost savings, as well as an improved user experience.

The Challenge

Key to the refurbishment was the need for the hotel to continue day-to-day operation with minimal impact on guests. When it came to the lighting, the team at the Frankfurt Marriott Hotel wanted to incorporate increased lighting control throughout each of the bedrooms, including full room control from the bed area, as well as the entrance way.

Wireless installation completed without disrupting hotel business.
Conventional switch installation was tricky as each room’s wiring ran back to centralised cabinets and due to newly installed ceilings; some of these were covered, which made them difficult to access.


Wireless Pico keypad provide bedside control

Using Lutron Energi TriPak controls, each guest room was transformed in under 30 minutes. Each room was retrofitted with three Lutron PowPak; one in the suspended ceiling in the bathroom, another in the AC box at the entrance to the room and a final one underneath the bed (to enable wiring to the floor lamp).

Three Lutron Pico keypads were used to replace the existing light switches. The Pico® controllers were programmed to talk to one or more of the PowPak wirelessly.


As a result of the wireless nature of Lutron’s latest retrofit light control solution, Energi TriPak, it was possible to fit out the entire 588 rooms ith minimal noise and disturbance.

The following savings were achieved:

  • Avoided loss of revenue of approximately €600,000 (£518,325)
  • Redecoration savings of €499,800 (£431,465)
  • In total, savings of almost €1.1m (£950,486) in comparison to a regular installation with standard switches
