DALI Lighting Awards 2023

Healthcare & Education

The state-of-the-art building provides new clinical facilities at the Royal Sussex County Hospital and incorporates a DALI-based lighting system with more than 20,000 assets including 4,300 self-contained emergency luminaires, 11,200 DALI -2 luminaires and around 2,300 DALI-2 multi-sensors.

DALI was selected as it fulfilled two essential design briefs, namely access to enhanced diagnostics, and future sustainability.

DALI data enables the client to look at the current health of the building, and then use that data to review space utilisation and also access information on power usage.

The lighting control system includes emergency lighting, and also integrates with the building management system. There is also the option for future integration of wireless DALI solutions, and of new sensor types specified in DALI Part 306.

A straightforward commissioning process and out-of-the-box functionality, along with a choice of certified products via the DALI Alliance database, streamlined the process of purchasing, installation, commissioning and handover.

Judges noted the lighting scheme with welcoming bright open spaces with effective splashes of color. They were impressed by the extensive use of data and the focus on sustainability summarized in the quote; “No other lighting product provides the security and longevity that DALI-2, and future versions of DALI, can offer.”

Highly Commended – Technical

Overall, the project transformed a former office building into a fully functional university campus. The issue of cabling presented a challenge, but the use of DALI significantly reduced the amount of cabling necessary in the field. The client saved over 20 thousand meters of cables compared to KNX or Modbus, and also enjoyed shorter test and commissioning times thanks to digital addressing available with DALI.

About 8,000 lighting fixtures were replaced and upgraded to be compatible with DALI technology. Over 1,100 sensors and push-buttons were strategically placed throughout the university campus to enable energy-efficient operations based on predefined scenarios. The 85 controllers were able to collaborate with each other through their integrated IP functionality.

Elekon said that DALI was used because it “was the only true lighting protocol offering the client a choice of drivers and fittings to suit the building’s needs”.

Judges were impressed by the wide range of DALI features used, and noted that DALI successfully replaced KNX as the protocol of choice for the project.
