the energy needed to light up the Paris metro

MASkargo is the Malaysia-based air freight division of Malaysia Airlines. The MASkargo Advance Cargo Centre, built in 1998, spans across 108 acres and processes up to one million tonnes of cargo annually, equipped with state-of-the-art cargo handling facilities.The cargo complex was previously lit with404 sets of 250W, 911 sets of 400W and 155 sets of 1000W metal halide lamps,generating an average lighting level of only 80 lux across the facility.
GE Project &Green Lighting Specialist, elaborated: “As aleading air freight company like MASkargo,operating 24 hours daily, it is vitalthatthe lighting solutionprovides adequate illumination while being efficient in its energy usage. After discussions with our clients and a thorough study of the work area, the team specified theirHi-Beam T5 High Bay system for this keycargo complex, which is a lighting system that hasbeen proven over time to be working well for a multitude of warehouse facilityareas. At MASkargo Advance Cargo Centre, the new lights presenta well-illuminated environment across the facility while halving the energy used. The Hi-Beam high bay on GE Lighting solutionsareamore environmentally-friendly and sustainable alternative for the businesses today.On an operational level, the GE solution will enable its client MASkargo to embraceenergy efficiency and enjoy improved annual savings amounting to an estimated US$300,000. Moreover, greater visibility and leveled-upillumination contributesto the security of the overall working environment.

Looking from an environmental perspective, the energy savings is equivalent to eliminating approximately 13,000 tons of carbon dioxide emissions per year, or creating 3,380 acres of new trees.The switch to LED will reduce the energy needed to light up the Paris metro and suburban RER stations by more than 50%, while improving the light quality at the same time. The contract was awarded by Parisian transport company Groupe RATP for more than 85% of the lighting in metro and RER stations in the French capital.The tender is to replace the 250,000 light points in RATP’s 302 metro stations and 66 RER stations with LED lighting.RATP aims to reduce its energy consumption and greenhouse gas emissions by 15% from 2004 until 2020. Energy-saving LED lighting from Philips and Step helps meet those objectives. The amount of electricity that the RATP's stations currently consume represents roughly 12% of its total energy consumption.
