The Abu Dhabi City Municipality has replaced conventional lighting on the Sheikh Zayed Bridge with an LED lighting system. The upgrade is expected to achieve energy savings of 71% and reduce maintenance costs by 80%.
The project is part of the Muncipality’s Abu Dhabi Plan 2030 strategy, which aims to adopt the highest international standards of sustainability. The Municipality is replacing traditional lighting with LEDs on roads, bridges, underpasses and public areas.
The main objectives of the Sheikh Zayed Bridge project were to improve the entrance to Abu Dhabi city, reduce power consumption and use environmentally-friendly devices that contain no mercury or dangerous materials. “The lighting performance on the bridge will look more elegant and bright with impressive colours unlike before,” says the Municipality. “It also contributes to a reduction of annual maintenance costs by not less than 80%.” The use of LED lights is said to improve traffic safety due to the clearer visibility on road and the lack of glare. The new lighting system is covered by a ten-year warranty.
In a comparative study between the new and old systems, the Municipality indicates that the new system achieves energy savings of about 71%.
As part of the wider sustainable lighting strategy, traditional lighting in Abu Dhabi subways has been replaced with LED lighting, resulting in an average reduction in consumption of 56%. The installation of LED lighting system below bridges in Abu Dhabi (Passports Bridge, Assaada Bridge, Al Muroor Bridge), has reduced energy consumption by at least 75%.
Abu Dhabi City Municipality has prepared the Public Lighting Guide, which is intended to disseminate lighting principles among all industry segments. The Guide, which consists of 500 pages comprising detailed information about the principles of lighting and technology, extends to buildings, parks and public squares.
