South Africa: Building Regulation Not Applied as Intended

Submitted by Baerbel Epp on February 1, 2015
SOLTRAIN stakeholder meetingExtended South African National Standard SANS10400 XA, Energy Usage in Buildings, is the big hope of the country’s solar thermal system suppliers. Part XA 2, which was added to SANS 10400 in September 2011, reads: "A minimum volume fraction of 50 % of the annual average heating requirement for hot water shall be provided by means other than electric resistance heating or fossil fuels.” The regulation applies to all new buildings with hot water consumption, as well as refurbished ones if the refurbishment requires planning approval from a local authority (for more details, see the attached architectural guide). After a transition period and a broad discussion among those affected by the new regulation, XA officially became law on 9 September 2014. The photo shows one of the stakeholder meetings within SOLTRAIN, the Southern African Solar Thermal Training and Demonstration Initiative.

South Africa: Ekurhuleni – Pioneering Solar Thermal City

Submitted by Baerbel Epp on December 13, 2013

It pays off to go green! No municipality in South Africa knows this better than the city of Ekurhuleni, which has recently been awarded the first prize in the national Greenest Municipality Competition and took home prize money amounting to South African Rand (ZAR) 3.5 million (EUR 248,000), as the South African Government News Agency (SA News) reported at the end of June. The Ekurhuleni Metropolitan Municipality (EMM), which was established in 2001 by merging nine towns, intends to become Africa´s first Aerotropolis, a city around Johannesburg´s OR Tambo International Airport as its urban core (see photo). But since airports are usually not the best examples of eco-friendliness or natural environments – what is it that makes Ekurhuleni so green? To come straight to the point: It´s the sun and its energy in all its facets.

SOLTRAIN: Free Solar Heating Systems for Social Institutions

Submitted by Baerbel Epp on May 16, 2012

 Solar Collectors at Kestell Children’s Home Two solar water heating systems – one at an old people’s home and the other at an orphanage (photo) – started operating this March thanks to an initiative by SESSA members Holms and Friends, and the Austrian Development Agency (ADA). Together with another system completed last year, the installations are part of an ADA pledge in support of the SOLTRAIN (Southern African Solar Thermal Training and Demonstration Initiative) project, which is coordinated by Professor Dieter Holm and Henning Holm of Holms and Friends (formerly Omnibus Engineering). Promised are more than 50 solar water heating systems (see http://www.solarthermalworld.org/node/3466).

South Africa: University of Pretoria’s 672 m² Solar Thermal System

Submitted by Baerbel Epp on April 12, 2012

 Onderstepoort campus The University of Pretoria is extending its Onderstepoort campus and this extension also includes a 672 m² solar thermal system. The system provides warm water to the new energy-efficient flats accommodating a total of 550 students. Onderstepoort - or OP, as it is commonly known - is located in Pretoria North and is home to South Africa´s only Veterinary Institute. Holms and Friends, formerly Omnibus Engineering, has recently completed the university project. With it, the member of the Sustainable Energy Society of Southern Africa (SESSA) has just set up one of the currently largest glazed installations in Southern Africa.
