Weathering the winter with energy efficiency

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 waives application fees for studies in 2016

2015-10-22

The University of the Free State (UFS) has waived application fees for all prospective undergraduate and postgraduate students - nationally and internationally - who want to study at the institution in 2016.

"Universities charge application fees that vary in amount. With 25 universities in South Africa, this fee becomes a burden for students who want to apply to more than one university. The university leadership has also realised that tens of thousands of students who qualify for university entrance stumble at the first hurdle: finding the money to apply,” says Prof Jonathan Jansen, Vice-Chancellor and Rector.

According to Prof Jansen, the UFS would like to set an example and a challenge to all public universities to scrap the application fee, so that many more young people from poor communities can realise their dream of accessing higher education. At the same time, the universities will benefit from more top talent coming into higher learning. "The more students that enrol and graduate, the stronger the financial position of universities will be; it is a win-win policy, and the university leadership has done the maths on this," he says.

The application fees for 2016 were R235 for South African students and R500 for international students. Prospective students, who have already applied for admission in 2016, will not be refunded. However, students who have already registered successfully for 2016 may apply to have the application fee credited to their tuition fee account after they have registered next year.

To support this initiative, UFS Marketing will be conducting an on-site application campaign by visiting East London, Port Elizabeth, Kimberley, Qwaqwa, Kathu, Pretoria, Johannesburg, Newcastle, Durban, Pietermaritzburg, and Ladysmith from 28 August 2015. Further details of the venues in each town will be available on the Kovsie2b Facebook page.

All prospective students currently doing their final-year undergraduate studies at either the UFS or any other university will also pay no registration fee if they want to continue with an Honours degree in 2016. The registration fee for 2016 was R950.

The closing date for applications for admission is 31 December 2015.

Apply for undergraduate or postgraduate studies at the UFS for 2016.
