Energy Saving Public Lighting in Malta6.2 BormlaAnother public garden where LED lighting could be installed is a popular spotoverlooking Grand Harbour’s Dockyard Creek, in Bormla.Figure 11 Google map of the garden at BormlaPresently there are no lights in this area. Stairs which are popular during thedaytime are not used in the evening due to lack of lighting, and installation ofproper lighting would thus be a welcome contribution to increased safetyand security.More lighting per square metre is necessary in this case, to overcome theinevitable shadowing by the many trees present. The total area of thegarden is approximately 1,850m 2 . If each LED light covers an area of 168m 2 ,the garden will require a minimum of 11 poles. To ensure enough lighting it issuggested that 14 lighting units are used, placed as shown in Figure 13.Malta Intelligent Energy Management Agency 22

On the other hand, with the use of LEDs, theCO2 emission would be of 1.666.575 kg per annum.6.3 GharghurAnother area identified where LED lights may be installed is a small square inGharghur overlooking the valley. A number of benches are present, makingthe site a popular one during the daytime. However, there is insufficientlighting at night.Malta Intelligent Energy Management Agency 23
