The iShack Project in Enkanini, Stellenbosch, South Africa

SAMSET project team members, municipal project partners and attendees from the CPD course “Energy and Sustainable Urban Energy Transitions in Africa” visited Enkanini on the 19th November 2014. Enkanini is an informal settlement in Kayamandi which was established in 2006, Stellenbosch, South Africa, and as part of the CPD course team members visited the iShack sustainability project, based in the settlement.

iShack is an organisation established in 2010, through collaboration with residents of Enkanini and  the University of Stellenbosch’s Sustainability Institute, promoting sustainability in the settlement across a wide range of applications. The “demonstration” shacks run by the project incorporate a number of energy-efficient and sustainable technologies.

Improved insulation and building materials were an early focus of the project, with leftover/recycled materials being used to insulate walls and ceilings, as well as innovative layered wall constructions offering cooling in the daytime without the use of air conditioning, improving the indoor environment.

Biogas is another focus of the project, and biogas digesters utilising human solid waste are installed in the demonstration shack bathrooms, enabling cooking from biomethane.

Water is another focus of the project. The project is expanding dissemination of grey water flushing for public bathrooms in the settlement, firstly in 2011 through gravity flushing. This approach has met with some resistance from residents due to the lack of convenience of the system, and the project is currently experimenting with upgraded mechanical flushing and collection systems for grey water and rain water.

Finally, the project also runs an off-grid solar home system business for residents of the settlement, and is aiming to develop this as a franchise model for export to other informal settlements, this being the first of these franchises. Solar home systems consisting of a 70Wp panel, two indoor LED lights, one TV, an outdoor spotlight and phone charging facilities are provided to residents on a fee-for-service basis, with customers paying an initial installation fee of R200, and monthly installments of R150 thereafter to use the system. Users can also choose to up-rate their panels to cover other appliances such as a radio or television. iShack takes responsibility for operation and maintenance of the system, and since 2011 over 700 systems have been installed out of 2,500 households in the settlement under the project.
