|The City of Cape Town, spurred on by its Energy and Climate Change Unit, has demonstrated its leadership, innovation and visionary qualities through its various campaigns and projects designed to ensure the responsible use of energy. This leadership at local government level demonstrates what can be achieved.
The electricity savings campaign targets residential and commercial consumers, aiming to reduce consumption through a wide range of behaviour-change actions. Through electronic resources, posters, publications, exhibitions and events, the campaign shares guidelines, information about energy technologies, and tips on electricity saving, to reach the widest possible audience.
The various elements of the Electricity Savings Campaign include an Energy Efficiency Forum for Commercial Building Owners, a Solar Water Heater Scheme, an Electricity Savings Website, and Youth Environmental School (YES) Programme with an electricity savings component.
Through its own building retrofit program the City demonstrated accountability. The project included a preliminary audit of 16 large administrative buildings and a detailed audit and the retrofit of four of these. The project has been completed. Results indicate a seven-year payback period and 22% savings. Technology retrofits implemented include installation of high-efficiency luminaires, control of air-conditioner operating hours, solar water heater installations, thermostat control, and power factor corrections.
This project was the first performance contract successfully implemented by a municipality in South Africa. Accordingly, this pioneering project can stimulate performance contracting across municipalities, with much anticipated benefits.
Furthermore the City of Cape Town has implemented a Traffic and Street Lighting Retrofit Program. Substantial electricity savings has been made by replacing incandescent traffic lights with light emitted diodes (LEDs). Since the implementation of this project in 2010, a total of 36 999 LED's were installed, 8 144 MWh/annum of electricity was saved and 8115 tCO2 emissions avoided. To date, 87% of all City traffic lights have been completely retrofitted. The City of Cape Town will be the first City to have completely retrofitted all its traffic lights to LEDs.
