Lighting - EcoBAY
Advantiv made one of the UK’s oldest industrial manufacturing plants producing steel wheels and rims for heavy earth moving and excavation equipment aware of the potential costs savings that could be made on their lighting systems by using EcoBAY.
Following meetings, a demonstration of the product and a survey of the plant, a proposal was put forward to outline the benefits and costs of installing the EcoBAY fittings. A trial was agreed and one area chosen to replace the existing high bay 400w metal halide lamps with the EcoBAY luminaires.
The aim of the trial was not only to demonstrate the reduced the lighting costs and therefore the lower carbon emissions, but also to improve the lux levels in the area as further inspection lighting had been required in addition to the metal halide lamps.
Results
A Tool room department lighting system was identified as having potential for an energy reduction study to be undertaken as the lights were high consumption 400w Metal Halide. 20 off lights were contained in the department providing enough light for detailed engineering work to be completed.
The lighting power consumption was monitored over the course of a seven day week and found to be consuming 9kw of power in total which equated 144kwh per 16 hour working day or 675kwh per week which in monetary terms equated to £33.75 per week. Over the course of a year this becomes £1870.
Ecobay Energy Efficient fitting were used with an integral PIR motion sensor to further enhance the energy reduction. The energy efficient fittings consume almost half the energy of standard metal halide fittings, an estimation was made of the potential energy reduction of approx 65% including the PIR system. The estimation was made as it was unknown how much more the energy consumption would be reduced utilising the PIR system as it was dependant upon foot traffic through the department.
All 20 fittings were replaced over a shutdown period and the lighting Installation was again monitored over the course of a normal working week.
The total consumption of the lighting Installation was 131kwh for the entire week, 26kwh per day. Therefore the total cost per year of running this section of lights was reduced to £350, an 81% reduction of power consumed not to mention the reduction in carbon emissions.
Not only did the energy consumption drop, but the lighting lux levels in the area also improved. These results have now instigated the rest of the lighting around the plant to be upgraded to the EcoBAY system.
The graph below outlines the energy consumption from both the metal halide lamps and also the EcoBAY fittings; the energy reduction can clearly be seen.
