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.

UFS shares expertise in Sign Language
2009-05-07

 
The University of the Free State (UFS) is continuing in its commitment to reach out to other universities on the African continent. Mr Philemon Akach (pictured), a senior lecturer in the Department of Afro-Asiatic Studies, Sign Language and Language Practice, recently visited the University of Ghana to share his expertise and assist in the introduction of the Ghanaian Sign Language (GSL) as an academic course in that institution. The course will first be piloted as an “elective course” and if successful it will be a permanent feature of the University of Ghana's calendar.

Mr Akach has been instrumental in the development of GSL since the United Nations Educational, Scientific and Cultural Organization (UNESCO) sent him on a fact-finding mission regarding the education of deaf children in Ghana in 1993. Since then he has trained interpreters as well as parents and teachers of deaf children in Ghana in using the South African Sign Language multimedia grammar teaching materials. He has also guided the GSL Dictionary Project. The University of Ghana will use his books as the basis for the teaching of the GSL. This session was a follow-up to the one he had with that university in February this year.

The UFS is widely regarded as a beacon of light in the teaching of sign language on the continent and, together with the University of Witwatersrand, are the only universities in South Africa that offer sign language as an academic course.
