An Bord Pleanála


Irish planning board An Bord Pleanála occupies a 5000m2 office building in Dublin. Facilities management services are provided by HOCHTIEF Facility Management Ireland Ltd, who recently undertook a major refurbishment of the lighting and lighting controls in the building.

The Needs

The aim of the lighting refurbishment was to create a substantially improved working environment for staff by raising the illumination levels in the reception and offices to current industry standards, while reducing the overall energy consumption by 50%.

The Solution

To achieve this goal, HOCHTIEF FM chose to use a variety of luminaires and lighting controls from Cooper Lighting and Safety, including RXD2 LED downlights, Modulay recessed fluorescent luminaires and DSI modular lighting controls, for which Cooper prepared detailed designs incorporating automatic daylight linking and occupancy-detection functionality.

The reception area is now lit by 36 RXD2 LED downlights, several of which are equipped with RXD wall-wash optic attachments. Utilising a multi-chip LED light source, the RXD2 consumes only 15W and achieves an efficacy of up to 68.2 lumens per circuit watt. Effective thermal management is provided by proven pure-water heat-pipe cooling technology, which transfers heat away from the back of the LED source to the cooling fins. This advanced method eliminates the need for large, heavy heat sinks and helps the RXD2 achieve a maintenance-free LED life of 50,000 hours.

For the building’s office areas, HOCHTIEF FM installed more than 400 Modulay 4 x 14W T5 high-frequency recessed fluorescent fittings. Cooper modular lighting controls provide daylight linking in the open-plan areas – automatically compensating for changes in ambient light levels – and occupancy detectors are used for automatic switching in all other areas.

The Result

An Bord Pleanála is delighted with the new lighting scheme, which has increased lighting levels by up to 50% and resulted in energy savings of 60%. The project was delivered and fully commissioned one week ahead of schedule.
