Architectural excellence celebrated at recent Sophia Gray lecture
Prof ‘Ora Joubert, a leading architect and academic, delivered the 30th Sophia Gray Memorial Lecture at the UFS.
A jolly kink, creative, aesthetically sensible, a dream house, welcoming, true colours, bright lights – these are some of the terms one can use to describe the work of Prof ‘Ora Joubert, leading architect, academic and former head of the UFS Department of Architecture.

A journey through time and space

She is also the 30th laureate to deliver the recent Sophia Gray Memorial Lecture on the Bloemfontein Campus of the University of the Free State (UFS). The lecture was titled: La Promenade Architecturale – A journey through time and space. “The title refers to the revelatory experience of an observer who wanders on a pathway in and through architectural spaces,” said Jan Ras, lecturer in the Department of Architecture and organiser of the event. 
“As the observer tours the architectural configuration, a sequence of composed images, themes and ordering systems are revealed. This gradually unfolds as the observer moves through the spaces,” Ras said.

The lecture, which coincided with an exhibition at the Oliewenhuis Art Museum, is a highlight of the South African architectural community and celebrates outstanding practitioners and academics in architecture.

Besides the numerous design awards she received as practitioner, Prof Joubert’s work has also received critical acclaim internationally in publications from Australia, to Russia and the UK. In 2001 she was cited as one of the most esteemed architects under the age of 40 and her work was included in the 2004 Phaidon Atlas of Contemporary Architecture. She is also a well-respected academic with 34 articles published in a variety of publications.

Recognising the intelligence and ingenuity of design

Prior to the lecture, the department also presented a mini-congress, introducing the new PhD with Design programme. This programme recognises the intelligence and ingenuity of design and is aimed at, among others, younger MArch graduates who wish to explore creative research. The department envisaged that the PhD study might be practice-based for architects who wish to document and research their own work and or design-led for candidates who wish to explore a new creative project. 

Forming part of this week filled with architectural creativity was a fundraising breakfast, with contributions going to the Sophia Gray Bursary Fund. The fund is part of a greater call to alumni and friends to be actively involved in the department’s continuous development and future endeavours towards imagination, care and excellence.

Fracking in the Karoo has advantages and disadvantages

Fracking for shale gas in the Karoo was laid bare during a public lecture by Dr Danie Vermeulen, Director of the Institute for Groundwater Studies (IGS). He shared facts, figures and research with his audience. No “yes” or “no” vote was cast. The audience was left to decide for itself.

The exploitation of shale gas in the pristine Karoo has probably been one of the most debated issues in South Africa since 2011.
 
Dr Vermeulen’s lecture, “The shale gas story in the Karoo: both sides of the coin”, was the first in a series presented by the Faculty of Natural and Agricultural Science under the theme “Sustainability”. Dr Vermeulen is a trained geo-hydrologist and geologist. He has been involved in fracking in South Africa since the debate started. He went on a study tour to the USA in 2011 to learn more about fracking and he visited the USA to further his investigation in May 2012.
 
Some of the information he shared, includes:

- It is estimated that South Africa has the fifth-largest shale-gas reserves in the world, following on China, the USA, Argentina and Mexico.
- Flow-back water is stored in sealed tanks and not in flow-back dams.
- Fracturing will not contaminate the water in an area, as the drilling of the wells will go far deeper than the groundwater aquifers. Every well has four steel casings – one within the other – with the gaps between them sealed with cement.
- More than a million hydraulic fracturing simulations took place in the USA without compromising fresh groundwater. The surface activities can cause problems because that is where man-made and managerial operations could cause pollution.
- Water use for shale-gas exploration is lower than for other kinds of energy, but the fact that the Karoo is an arid region makes the use of groundwater a sensitive issue. Dr Vermeulen highlighted this aspect as his major concern regarding shale-gas exploration.
- The cost to develop is a quarter of the cost for an oil well in the Gulf of Mexico.
- Dolerite intrusions in the Karoo are an unresearched concern. Dolerite is unique to the South African situation. Dolerite intrusion temperatures exceed 900 °C.

He also addressed the shale-gas footprint, well decommissioning and site reclamation, radio activity in the shale and the low possibility of seismic events.
 
Dr Vermeulen said South Africa is a net importer of energy. About 90% of its power supply is coal-based. For continued economic growth, South Africa needs a stable energy supply. It is also forecast that energy demand in South Africa is growing faster than the average global demand.
 
Unknowns to be addressed in research and exploration are the gas reserves and gas needs of South Africa. Do we have enough water? What will be the visual and social impact? Who must do the exploration?
 
“Only exploration will give us these answers,” Dr Vermeulen said.
