Suffolk County Council plans to cut carbon dioxide emissions, energy costs and maintenance for streetlighting on major arterial routes in the area.
The county streetlighting department and maintenance contractor Carillion – along with electrical services manager Richard Webster – have been asked to fi nd ways to achieve this. One of the troublesome routes that has been tackled fi rst is the A1120 Cedars Link on the outskirts of Stowmarket in the centre of the county. The team decided the best option would be to use LED lighting, because the cost of maintenance and traffi c management when the lighting fails is a drain on funds. Luma LED fi ttings from Indal, were specifi ed. The council also introduced a central management system (CMS) that dims fi ttings during the night when traffi c is lighter and there are fewer pedestrians around. The council implemented the CMS in residential areas, subject to pre-determined criteria, where fi ttings can be switched off remotely between midnight and 5.30am. In the past six months, more than 30,000 fi ttings have been installed and are working with the CMS.
The council hopes the intelligent lighting system will cut its energy bills by £850,000 a year. Suffolk’s goal is to cut carbon dioxide emissions by 60 per cent by 2025. The Cedars Link scheme alone reduces energy consumption by 63 per cent along the road and should prevent the emission of 1,000 tonnes of CO2
over a 25-year period.
LEDs, combined with reduced operating hours and CMS dimming, could cut CO2
4,000 tonnes by April 2013. emissions by over
