Solar Panels at UFS Qwaqwa Campus
Revolutionising electricity with sun power: Solar panels at the Qwaqwa Campus.

Over the past few years the University of the Free State (UFS) has been planting panels, now the time has come to reap. Solar farms produced a return on investment in the form of R1.4 million in savings as a result of photovoltaics (PV) between January and March 2019. Nicolaas Esterhuysen, an electrical engineer at the Department of University Estates also reported a 2.34% decline in electricity usage between 2013 and 2018. 

Solar panels are the future 

According to Esterhuysen, the solution to a power crisis lies in “either becoming more energy efficient or generating our own at a cheaper cost”. All campuses have managed to save a total of R5.4 million in 2018 through producing our own power (solar PV) and actively managing the instantaneous load demand with building management system (BMS) software.

Overall, ground-mounted PV installations at all campuses contribute 2609 kilowattpeak (kWp) under standard conditions. The Bloemfontein Campus accounts for 979kWp of that amount while the South Campus generates 762kWp, with the Qwaqwa Campus producing 748kWp, and the Paradys experimental farm bringing in 120kWp to the grand total (to be commissioned June 2019).

Rooftop PVs generate electricity through the 80kWp Muller Potgieter Building, the 255kWp Bloemfontein Campus computer lab, the 35kWp Qwaqwa Campus computer lab, 135kWp Qwaqwa Campus Mandela Hall, and 416kWp Thakaneng Bridge panels. This is a total of 921kWp. 

Winter is coming with tariff terrors 

A 15.63% electricity tariff increase is projected this year in light of the annual winter adjustments commissioned by Eskom and Centlec. To gear up for the associated spike in power use over this season, University Estates advises the Kovsie community to use energy efficiently. “Think twice before switching on the heating and make sure to switch it off when you leave the office,” advises Esterhuysen.

In addition to generating electricity, saving initiatives such as implementing light-emitting diode (LED) lighting with motion sensors and actively managing demand at peak times have been implemented.

What’s next?

The next step is to rethink dated mechanical installations that are used to heat some of our older buildings. Replacing similar installations across all of the campuses are some of the ways the university intends to escalate energy efficient in future.

Alumnus presents 27th Sophia Gray Memorial Lecture

In a packed Civic Theatre in Bloemfontein, Anton Roodt, an alumnus from the UFS Department of Architecture, presented the 27th Sophia Gray Memorial Lecture.
 
Roodt received numerous awards for his work during his career. He also completed three masters degrees at the UFS, all of them cum laude.

The theme for his lecture was: Big dreams in a small city. Places of memory¦Spaces of imagination.
 
In his presentation, he focused mainly on President Brand Street, one of the most beautiful streets in South Africa – a gem waiting to be rediscovered, as well as Waaihoek, where many projects are planned for the future.
 
During his career, Roodt has been involved in various projects in these areas, including the Fourth Raadsaal, for which he received a FSIA Award in 2011. The Mapikela House in Batho is another project he was involved in.
 
He believes universities are small cities with a good deal of ambition. A number of infrastructure projects on the campuses of the UFS were designed by Roodt Architects. On the Bloemfontein Campus, this includes the Student Centre on the Thakaneng Bridge, the Main Gate, the Financial Planning Law Building, and the Computer Centre, as well work done on the Albert Wessels Auditorium. They also designed the dining room and the Main Entrance on the Qwaqwa Campus.
 
Roodt was introduced to the audience by the familiar singer and his university friend, Coenie de Villiers, with the question: “Why architecture?” He replied: “It is one of the best professions to take you to places most people will never be able to visit – sometimes literally to the feet of kings.”
 
Roodt believes that architects are sellers of dreams. “Dreams are the purest form of imagination. Architects dream of places as if people matter,” he said.
 
The Women in Architecture initiative was also launched by the South African Council for the Architectural Profession at the event. Of more than 8 800 professional architects, only 21% are women.
