The Association of Chartered Certified Accountants (ACCA)


Bringing Daylight to the Working Environment Using LED Technology

At the end of 2015, ACCA - the Association of Chartered Certified Accountants - moved out of the three Holborn offices that had comprised its London headquarters since the 1970s and into two newly fitted-out floors of the Adelphi Building in London’s West End.

The move was designed to encourage collaborative working, with new flexible meeting spaces and a more appropriate level of technological support. ACCA’s intentions were to give staff a world-class headquarters that combined its heritage with a modern business approach.

Cushman & Wakefield, commercial property and real estate consultants, appointed Bluu Solutions to help design and fit out their property for ACCA. When it came to the lighting for the main reception area, the design brief required a non-standard solution to an everyday problem - how to mount light fittings beneath a fan coil unit to create an aesthetic skylight panel effect but still enable quick and easy access to the equipment mounted above the lights?

WILA’s UK based design team came up with the solution of combining individual 850x850mm panels that clustered in groups of 4 or 9, mounting on to a quick-mount frame above to create an artificial skylight effect to the whole reception and office area below.

Due to the location of the building’s air handling system unit being directly above where the lighting required, WILA’s design team had to work around this to minimize the risks. The LED drivers were mounted to the side of the arrangement in a waterproof enclosure, leaving only low voltage fittings directly below the fan coil unit.

The design team and installers worked closely together to ensure that the optimum lighting levels were achieved and that the integration of the lighting panels in to the surrounding ceiling worked seamlessly.
