The Solution.
Advanced Lighting Control for Enhanced Energy Efficiency
Central to this retrofit is an advanced lighting control system, utilizing LOYTEC’s LDALI-ME204-U controllers. Each controller manages up to 256 DALI luminaires, ensuring efficient lighting throughout the convention center, excluding the auditorium. With 22 controllers covering 88 DALI channels, the system integrates Erco and Philips luminaires using the DALI protocol and communicates with the building management system via BACnet IP.
Intelligent Lighting for Optimal Performance
The constant lighting control system, which adjusts for presence and brightness, significantly enhances energy efficiency. Approximately thirty LDALI-BM1 Push-button Couplers allow manual lighting adjustments during presentations. The system’s robust fault reporting has shown no lighting failures in two years of operation, highlighting its reliability and efficiency
