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.

Two Kovsies crowned at Miss Deaf SA

2014-10-16

The new Deaf Miss South Africa was announced – and Elzane van den Bergh, a Kovsie student, was crowned the winner. Elzane, a final-year BEd Foundation Phase student, also won the title for Best Talent at this swanky event.

Another Kovsie student, Elrie du Toit, was selected as second princess. She was also among the top five for the Best Talent title. Elrie is currently studying to become a social worker.

Twelve finalists from all over South Africa, all deaf or hard of hearing, took part.

On the competition at Miss Deaf South Africa, Elzane’s thoughts are that the judges had a very difficult choice to make. “Each talented girl had some special characteristic that stood out,” she relates.

“I really wanted to do something like this as it would help to make a bigger difference in the community and motivate people to accept themselves for who they are, because we are all uniquely created.”

Elzane’s focus is on teaching basic sign language to hearing parents with deaf babies. She also believes that hearing people should be made more aware of the deaf culture and language. This will eventually lead to deafness no longer being perceived as a disability.

Hard work and preparations are now lying ahead for Miss Deaf World, which will be held in Prague during June next year.

“Never allow any disability or obstacle to stand in the way of your dreams,” says Elzane. “Stick it out and don’t doubt in your abilities for one second, because you were born to be a winner. Be proud of yourself, no matter what.”
