Lighting rafts expose thermal mass of headquarters building

Enabling the thermal mass of this new headquarters building in Dublin to deliver 25 W/m2 is the use of SAS Internal acoustic lighting rafts.
SAS International acoustic lighting rafts are playing a key role in reducing the carbon footprint of the new headquarters of the Commissioners of Irish Lights (CIL) in Dublin by enabling the thermal mass of the building to be exploited. The ceiling has been designed as a feature in its own right. System 600 ceiling rafts have been installed in radial coffers throughout the open-plan office. They are perforated acoustic rafts that incorporate luminaires. This alternating design has been enhanced by coffers with curved ends to emphasis the circular nature of the atrium. System 600 rafts expose the concrete soffit, allowing the thermal mass of the building to be exploited. By allowing free air movement to the exposed concrete slabs, 25 W/m2 of cooling can be achieved — while offering design flexibility and reducing capital and installation costs. The building was designed by architects Scott Tallon Walker, whose project director David Cahill says, ‘Our brief was to design a 21st century landmark building which was also sensitive and reflective of the surrounding historic structures and marine environment. We worked with SAS International to design a ceiling system that would serve as one of the building’s features while ensuring that we adhered to CIL’s vision statement of delivering reliable, efficient and cost-effective services to the navigation industry.
