A few days after the annual Sophia Gray lecture, the Department of Architecture at the University of the Free State (UFS) hosted the inaugural lecture of Prof Jeremy Smith.

Prof Smith, the Design Director of Irving Smith Architects in New Zealand and an Adjunct Professor in the UFS Department of Architecture, is known for his innovative approach to architecture that emphasises sustainability and the relationship between buildings and their natural surroundings.

Earlier this year, he partnered with RTA Studio – an architectural firm based in Auckland, New Zealand – and won the prestigious Dubai International Best Practices Award for Sustainable Development in the category of the Most Beautiful, Innovative and Iconic Building with the entry: The ‘Scion Innovation Hub, Te Whare Nui O Tuteata.

A changing climate

Themed Being Finished is Finished, the lecture attracted a diverse audience of architects, industry stakeholders, academics, students, and the general public. Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation, welcomed Prof Smith and the attendees. He congratulated Prof Smith on this milestone, highlighting that a professor’s work often represents the beginning of much unfinished business. He noted that the UFS is proud to host such lectures, which celebrate and acknowledge excellence in research and practice.

Prof Paul Oberholster, Dean of the Faculty of Natural and Agricultural Sciences, introduced Prof Smith, praising his impressive career and the numerous national and international awards he has received.

Prof Smith’s lecture focused on the evolving relationship between architecture and the landscape, particularly in New Zealand, where only a quarter of the original forests remain. “We know our climate is changing. In New Zealand we massively made landscape; landscape is everything. Modernism has asked us to use the lawnmower,” he remarked.

He believes in the importance of architecture that adapts and evolves within its natural surroundings, rather than imposing new landscapes. He introduced the concept of ‘soft architecture’, which involves designing buildings that fit into the changing landscape. This approach allows for a sustainable relationship between architecture and nature, ensuring that buildings enhance rather than dominate their environment.

He illustrated this philosophy with a project, the ‘Bach with Two Roofs’ house, which was damaged by a cyclone in 2014. The storm altered the surrounding landscape, and rather than simply repairing the house, Prof Smith redesigned it in a flexible and adaptive manner that might accommodate environmental change. This project demonstrated how buildings can be refurnished to adapt to a shift in the landscape, ultimately coexisting with and responding to the natural world.

“From life in the forest, the landscape shifted – the sun was hotter, the wind was stronger. Our building has lost its fit to the landscape. Refurnishing it, we need to acknowledge that this time a new forest will grow. It will be a stronger forest – it will be indigenous and will grow in relation to the building. In this shifting landscape, it’s not the landscape that needs to be refurnished. It is the building.”

Doing more with less

Prof Smith also discussed two award-winning projects: the ‘Te Whare Nui O Tuteata’ project and the ‘Feather House’. Both projects are examples of his commitment to sustainability and adaptive design – doing more with less.

The ‘Te Whare Nui O Tuteata’ project, part of the New Zealand government’s SCION Timber Research Institute, uses a diagrid timber structure that reduces material usage and allows the building to integrate seamlessly with its forest surroundings. The building was designed with a neutral carbon count, and the timber used was locally sourced, reflecting the natural landscape.

Prof Smith described the building as an educational invitation to visitors to ‘walk in our forest’ and learn new and sustainable ways of resourcing and building with timber. “The building behaves like a forest – the closer you get the more is revealed. Light filtering through its timber framework is also much like sunlight through a forest canopy – enhancing the building’s connection to its surroundings.”

In discussing the Feather House, Prof Smith highlighted the importance of designing spaces that can evolve with their inhabitants. “Design for the ‘there and then’ rather than for the ‘here and now’,” he said. “One cannot design a room for every occasion, but you can provide an invitation.” He advocates for creating architecture that anticipates future changes and adapts to evolving environments, ensuring that buildings remain relevant and functional over time. His design philosophy underscores connection rather than division of spaces and doing less rather than more to create adaptable and sustainable living environments. “Do not design the space based on whose shoes are in the shoe rack,” he commented.

Researcher part of project aimed at producing third-generation biofuels from microalgae in Germany

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today. However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security. The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs. These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene. Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required. A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously. The three systems are from Novagreen, IGV, and Phytolutions. The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm. The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project. However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad. In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre. “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
