Mixed-mode DALI solution

Originally constructed in 1999, Ludgate London has undergone a complete refurbishment including the addition of a site-wide smart lighting management solution to provide sustainable, energy-efficient monitoring and control of lighting. The cutting edge Delmatic mixed-mode DALI Buswire and DALI Plug-in system, together with DALI presence detectors and multisensors applied across the site have resulted in increased energy savings and the achievement of a BREEAM “Excellent” sustainability rating.

Totally flexible and scalable

Delmatic’s DALI Buswire and DALI Plug-In modules deliver versatile, scene-setting control of lighting throughout the shell and core, basement, reception, rooftop terrace and retail spaces, while also being totally flexible and scalable to meet the individual requirements of tenants within the office floors.

Smart IOT integration

The state-of-the-art system individually addresses and monitors every luminaire, and empowers tenants with the ability to precisely configure control and operation of lighting and integrated services within their domain: further tenant customisation includes circadian tuneable-white scenarios, user control from web-browser and Apps, heatmapping and space analytics as well as full smart IOT integration through wired, wireless or mixed-mode devices.

Operational efficiencies and sustainability

Delmatic’s DALI multisensors and presence detectors applied across the site optimise energy-efficiency by adjusting lighting levels to changes in occupancy and daylight, while custom-configured scene-set panels provide scene-based control of lighting. The entire lighting network interfaces with the BMS via BACnet/IP and shares real-time sensor data with other energy consuming services to maximise operational efficiencies and sustainability.

Delmatic’s advanced graphical user interface with enhanced emergency monitoring and testing features, provides unmatched, real-time intelligence and powerful tools for managing and monitoring the lighting network. The software highlights lamp and driver failures in real time and logs the number of hours each lamp has been in operation, generating relamping schedules and ensuring lamps are sustainably replaced at the optimum point.
