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.

The University of the Free State’s (UFS) Department of Law of Procedure and Law of Evidence again presented the First-year Moot Court Competition this year. This interuniversity competition was presented for the fifth time this year. The Universities of the Free State, Pretoria, Johannesburg, Rhodes, North-West, Zululand and KwaZulu-Natal (both campuses), as well as an international institution, the Charlotte Law School in North Carolina in the USA also participated in the competition.

The last-mentioned participant was indeed a highlight for the Department of Law of Procedure and Law of Evidence. The students of the Charlotte School also initiated a community service project for a school in a disadvantaged community. According to Adv. Mariëtte Reyneke from the Department of Law of Procedure and Law of Evidence, the students of the UFS’s Faculty of Law will also participate in this project. The team’s participation is a result of negotiations to work together between Prof. Neels Swanepoel, departmental head, and the Charlotte School of Law early in 2009 as part of the university’s internationalisation priority.

“We are really excited about the growth of the competition that started out with three universities to where it is today. We believe that it is a cause for celebration,” said Adv. Reyneke.

Only first-year students may participate. The competition will take place in the High Court and the final rounds in the Court of Appeal. The judges are compiled from retired judges, practising judiciary, magistrates as well as retired lectures of law. Only a small number of law practitioners get the opportunity to appear in the Court of Appeal and to do this in your first year in front of a judge is an excellent exposure and career forming. This is also the only competition in the country where students can participate in either an English competition or an Afrikaans competition.

Sixteen English teams (9 universities) and 7 Afrikaans teams participated in this year’s competition.

At the prize giving function the UFS team was crowned overall winners of the Afrikaans section and a team from the University of Pretoria as overall winners of the English section of the competition.
