Balancing the bottom line with an environmental conscience.
Posted date 10 July 2009
Green Technology Solutions conducted a trial of our LEDlights tube at IGA supermarket in Elizabeth East.
Based on the typical wattage of the lamps used at Elizabeth East store and the estimated daily operational hours;
the total weekly energy consumption for lighting came to 1,724kW. Based on this figure, the annually the energy
consumption is estimated at 88,698kW. At a nominal 1.2kg of CO2 per kWh; this equates to around 106.4 tonnes of
carbon emissions a year.
If the majority of the current lamps were replaced with Green Technology Solutions’ LED technology;
lighting energy consumption would be reduced overall by around 66.7% to 29,566kW and carbon emissions
would be reduced by 71.0 tonnes to 35.5 tonnes.
Assuming an average energy cost of $0.18 per kWh; the total energy reduction would be a cost saving
of around $10,644 per year.
The following photos were taken before and after a single row of lights were retrofitted with Green
Technology Solutions' LEDlights tubes.
