67% energy saved with LED – Belfast City Hall

Replacement of over 400 existing luminaries on the façade and domes of City Hall with new SSL devices that enhances architectural features, links building elements more effectively, and provides dynamic lighting scenes to complement local events while contributing significant savings on electricity costs and maintenance.

433 light fittings installed on and around Belfast City Hall, each of which can be individually controlled to provide both static and dynamic scenes which can call on a palette of 16 million different colour options.
The installation is the largest “Intellipower” system in Europe using “Ethernet over power” technology to transmit data signals over the existing mains cabling within the City Hall. The Intellipower system allowed the internal cabling to remain in situation, minimizing disruption within the building, and causing no aesthetic issues. The system is based on an astronomical clock with lights switching on or off based on the sunrise and sunset. However, additional flexibility has also been added with the ability to hand control over to a lighting desk, similar to those used at concerts.
But the real focus is on generating savings, both in terms of operating and maintenance costs. The system reduces the annual electricity bill by around € 22,960 per year and thus reduces carbon emissions by 40 tonnes. Maintenance costs should also be reduced by around € 6,950 per year as the SSL lighting devices have a potential 10-year life-expectancy, whereas the old scheme involved substantial re-lamping each year.
