At the 2019 ECA(SA) Presidential Excellence Awards, elex khanyisa Electrical Contractors received the Best Contributor to Energy Efficiency award for the retrofit of Green Point Athletics Stadium’s track and pitch floodlighting with high efficiency LED floodlighting. BEKA Schréder supplied the locally manufactured LED floodlights.
The project was tasked by the City of Cape Town under the Detailed Energy Audits and Lighting Efficiency Interventions at Council Facilities contract; the purpose being primarily to decrease the energy demand of the facility but also to increase the value of the Stadium as a City asset. Green Point Athletics Stadium, partially demolished before the 2010 FIFA World Cup to make way for the Cape Town Stadium, was subsequently refurbished. The facility is a strategic asset, reconstructed as a recreational facility for enjoyment by the public.
The LED retrofit has reinstated the facility to a high-quality venue with ample lighting at lower operating costs and the upgrade is expected to attract new opportunities for international sporting events. The project entailed replacing 35 2 kW high intensity discharge floodlights with lower wattage LED floodlights, while achieving the same or higher quality light on the track and pitch. elex khanyisa’s lighting design increased the lighting levels and lighting quality, while reducing the power demand of the system by 23 kW, a 33% reduction in load.
The design work was a collaborative effort between elex khanyisa project manager, Jamie Pothier, Grant Kemp and Therlo Brown from BEKA Schréder, and Senior Professional Officer Oliver Stotko from the City of Cape Town. “This forms part of the City of Cape Town’s overall LED retrofitting programme, which has been ongoing for almost a decade. The city’s emphasis on cost and energy efficiency, while honouring a climate-friendlier way of operating, remains an important driving force to enable a more future-fit development pathway for Cape Town,” said the City’s Sustainable Energy Markets Department, Senior Professional Officer Oliver Stotko.
The benefits of LED floodlights over the previous HID floodlights include:
The previous floodlights resulted in a very low power factor (0.8) and consequent high maximum demand when in operation, while the new LED floodlights have a much lower influence on power factor (0.98). BEKA Schréder locally develops and manufactures LED lighting products, designed and suitable for African conditions. The company is proud to have worked with elex khanyisa electrical contractors and the City of Cape Town to provide a successful LED floodlighting solution for this prestigious project.
