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.

Valuable opportunity for future educators

2012-02-13

The UFS will award bursaries to about 670 students this year. These bursaries, to the value of over R42 million rand, will give these students the opportunity to follow their dream of becoming educators in South Africa. At the selection process were, from the left: Prof. Gawie du Toit, Programme Director: Initial Teacher Education at the UFS, Dr. Rantsie Kgothule, Teaching Practice Coordinator at the UFS Qwaqwa Campus; Ms Fiona Padayachee, Deputy Director: Recruitment and Selection in the Free State Department of Education; and Mr Kennedy Vilankulu, Information Manager at the Fundza Lushaka bursary scheme.

This year, 675 students from the University of the Free State’s (UFS) Faculty of Education will be awarded bursaries worth more than R42 million from the Fundza Lushaka bursary scheme.

The selection process for the recipients is already underway. Although each student’s academic performance plays a vital role in the selection process, beneficiaries are also selected based on performance in scarce subjects like mathematics, science and African languages.

“We are trying to attract and train as many teachers as possible. Hoping they will honour their contract and teach in South Africa” said Mr Kennedy Vilankulu, Information Manager at the Fundza Lushaka Bursary Scheme.

Mr Vilankulu commended the faculty on its management of the bursary scheme. This is evident in the close liaison between the faculty, on both the Bloemfontein and Qwaqwa campuses, and the Free State Department of Education. Just over 90% of the beneficiaries of the bursary scheme study at the UFS.

Prof. Gawie du Toit, Programme Director: Initial Teacher Education (ITE) says the quality of a school can never exceed the quality of its teachers. It is the faculty’s aim to educate caring, accountable and critically reflective education practitioners. These teachers must be able to act as agents of change in diverse educational contexts. Prof. Du Toit said it was a privilege to collaborate with both national and provincial Departments of Education in this venture.
