DALI Case Study: Old Admiralty Building

September 25, 2020

The installation of a DALI lighting-control system is a fundamental aspect of a major refurbishment project at the Old Admiralty Building in London.

Halsion, the project’s principal mechanical and electrical contractor, selected CP Electronics (part of the Legrand Group) to supply its fully addressable and networkable RAPID lighting control system.

Almost 7,000 DALI-addressable luminaires are controlled and monitored by the CP system. The company also supplied 1,800 PIR devices within the refurbishment to detect occupancy in different parts of the building and activate lighting accordingly.

The design and installation team faced a number of challenges; decorative cornices and wood panelling could not be disturbed so the installation of wiring routes and DALI cabling required careful consideration and planning.

“The main design challenges were due to the nature and scale of the installation,” explains Rob Crookes, Systems Project Manager at CP Electronics. “A DALI-based lighting control system was an obvious choice, especially as DALI is a long-established protocol which is very stable over large-scale installations.”
