The City of Cape Town recognises that resource efficiency is critical to building economic activity and increasing a city’s competitiveness and resilience.
This is reflected in the City’s recently approved Energy 2040 Goal, which includes a 37% reduction in carbon emissions, with 22% coming from energy efficiency alone.
The Energy 2040 Goal models a more resilient, lower carbon, resource-efficient and equitable future for Cape Town, which grows the administration’s stature as a leading and innovative city.
The targets for 2040 will also result in:
- The installation of over 500 000 solar water heaters and heat pumps by residents
- Less dependency on coal, with extensive embedded renewable generation in the commercial and residential sectors as well as diversified large-scale energy supply with photovoltaics, wind, storage and possibly natural gas
- A modal shift from private to public transport, with increased access to public transport and motorised passenger travel in efficient vehicles with higher occupancy levels
- A remodelled city with increased densification and mixed use in areas of economic activity
- Increased energy savings from efficiency and cheaper energy
Given rising electricity tariffs and the serious constraints on South Africa’s electricity supply, energy efficiency is critical to economic growth and stability.
The commercial sector uses an estimated 44% of the electricity supply in the Cape Town area.
This year, Bayside Mall and the Cape Town French School have been named as the winners of the 2015 Energy Efficiency Forum Awards, announced at the forum award ceremony which took place this morning, 10 November 2015.
The winners have been recognised by the City of Cape Town and our partners for helping to make sustainable progress possible through significant reductions in their energy consumption.
The adjudication was done by the Energy Research Centre’s (ERC) Monitoring and Verification Unit, based at the University of Cape Town. Entrants were judged on their commitment to reducing their operational energy needs through behavioural change as well as technology upgrades.
They had to demonstrate that they were reflective about their own systems, policies and investments and that they were dynamic enough to change the way they operated to maximise energy efficiency without compromising productivity.
The award for the Large Building Retrofit Category was scooped by Bayside Mall
Their energy efficiency interventions include upgrading to LED lighting, and improvements in the heating, ventilation and air conditioning system.
The flagship project is a 500 kWp pilot rooftop solar photovoltaic (PV) plant, with 2,108 panels covering 3,300m² and which supplies 5% of their electricity needs.
The annual average daily energy production of the PV panels is 2100 kWh, which equates to the average daily use of 105 middle-income households in Cape Town (using 600 kWh per month.)
The installation of PV panels has resulted in carbon emission reductions equivalent to 767 tons of CO2. The interventions have yielded consistent monthly energy savings averaging at 11% so far, with the hot summer months still to come where savings reach about 17%.
Bayside Mall, owned by Growthpoint Properties, has moved beyond basic lighting retrofits and peak demand reduction, and its pioneering efforts have set it apart as an exemplary custodian of energy resources.
The winner of the Small Building Retrofit Category is the Cape Town French School
Over the past three years, the school has been working on energy efficiency and adding renewable energy to their operations, with the help of Energy Intelligence. They have replaced all fluorescent lights with LED technology, and installed a heat pump for hot water.
Their rooftop solar photovoltaic (PV) system provides about 20% of the school’s usage during the week, and they can feed back to the City’s grid over weekends and receive an offset to generate valuable income for the school. So far they are saving 15% on their electricity costs overall.
