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.

International speakers discuss diversity

International and local experts recently gathered on the Bloemfontein Campus to deliberate over the topic of diversity.

Student participation and mobility dramatically increased in higher education worldwide. Cultural, political, economic and social factors on a national and global scale, have brought the reality of diversity into the operational spaces of Higher Education Institutions. These challenges are not exclusive to South Africa, though. In the Netherlands and USA, universities are also challenged by the demands of an increasingly diverse student population.

Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, acted as one of the keynote speakers during a two-day colloquium hosted by the Institute for Reconciliation and Social Justice. In an impelling address, Prof Jansen argued that change cannot be affected on a university campus if the surrounding community does not change as well. He also noted the spread of a culture of silence surrounding issues of misbehaviour. He urged that we need to find courage again to speak out. From the level of government, media and churches to the private spaces of our homes, we have to co-create an environment of care.

This message closely tied in with that of Prof Shirley Tate’s from the University of Leeds. In her keynote, she asserted that mere tolerance of someone different from you can lead to even more alienation. The path to true reconciliation is grounded in the intimacy of friendship. Friendship and empathy lead to trust and transcend racism.

Another keynote speaker from abroad, Dr Charles Alexander from the University of California, delineated a model for inclusive excellence. He explained that the major problem of true transformation is not due to a lack of ideas, but in the implementation thereof. “Realities of implementation short circuit the change process,” he said. He explained how campus environments can adapt in order to support and enhance lasting inclusivity.

We have to become complicit in the process of transformation, Prof Dr Ghorashi, Professor of Diversity and Integration at the Vrije Universiteit Amsterdam, conveyed. Linking up with the issue of silence, she demonstrated the power of speaking out, using examples from her extensive research among victims of violence. It is imperative, she maintains, that for transformation to materialise, we need to create safe spaces in which we can share our vulnerabilities.

Footnote: Due to unfortunate circumstances, both Prof Dr Ghorashi and Prof Shirley Tate could not personally attend the colloquium as planned. Their respective keynotes were read to the audience on their behalf.
