Harvesting light to save energy

Over the summer the skylights above NPIL’s MDF Line 3 were replaced, letting in a lot more light, in a measure that’s technically known as ‘daylight harvesting’. This is now saving on the power bill, and the same area is the first to come in for an LED lighting trial.
The new lights have movement and daylight sensors – if there’s enough daylight they switch off, and if there’s been no movement they dim after five minutes and switch off completely after an hour. It takes 90 percent less energy to produce light using LED, as there are over 1000 light fittings right around the plant, there are considerable savings to be made through LED conversion.
