Judges' comments

The WINNER of the DALI Lighting Award in the Retail & Hospitality category is Inverse Lighting Design for The Londoner, a new boutique hotel in London, UK.

Over 17,000 DALI luminaires were used to achieve dramatic lighting for the guest-accessible areas, soft lighting for the guest rooms, and functional lighting for the staff areas.

Judges recognized the primacy of lighting design in a unique space with many underground levels, which creates a significant challenge to get the scene-setting correct and achieve a balance between natural and artificial light.

The judges were also impressed with the very extensive use of DALI features including colour control and white tuning, energy usage reporting, and testing and monitoring of emergency lighting.

Automatic mood setting through the day is achieved without staff intervention by using time-clock events in combination with long fade times. A key benefit that DALI provides is the ability to adjust the lumen output of a single luminaire to compensate for lumen depreciation, therefore maintaining a consistent aesthetic.

Project overview

The Londoner is a boutique hotel with 350 rooms, 35 suites and public areas over 16 floors, 8 above and 8 below ground. It required dramatic lighting for guest accessible areas, soft lighting for guest rooms, and functional lighting for staff areas – with a balance between natural and artificial light.

Over 17,000 DALI luminaires were used, and wireless sensors and controls provide flexibility. Using DALI luminaires with Lutron's lighting control system enabled automatic mood setting through the day, such as colour changes, without staff intervention, by using timeclock events in combination with long fade times. Additionally, white tuning for staff offices mimics daylight and enhances wellbeing and comfort.

The system provides fault reporting, finding and servicing to reduce disruption, as well as energy usage reporting. If a luminaire must be replaced after a few years, DALI provides the ability to adjust the lumen output of a single luminaire to compensate for lumen depreciation, therefore maintaining a consistent aesthetic.

The system also supports emergency lighting testing and monitoring. This saves a significant amount of money in operational costs, and minimizes disruptions.

Through Lutron's control system, it was possible to combine the DALI lighting with DMX lighting seamlessly. The lighting system is also connected to the Building Management System vie BACnet.

For the future, DALI provides flexibility to re-zone and adjust the layout with software revisions, without changing the infrastructure.

The Londoner shows that DALI is more than just a tool for building automation and energy management, and can also deliver unforgettable experiences.
