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.

Take up the challenge, make things happen, and emulate the greats. This was the overwhelming theme of messages from speakers to graduates at the Winter Graduation ceremonies of the University of the Free State (UFS).

According to Prof Joel Samoff, Professor in Africa Studies at Stanford University (USA), the graduands are the “new generation of analysts, researchers, and practitioners”, and should “assume the responsibility for keeping your senior colleagues on a productive path.” Prof Samoff, who received an honorary doctorate from the UFS on 30 June 2016, was the guest speaker at the afternoon graduation ceremony on 29 June 2016.

The UFS awarded a total of 482 Master’s and doctoral degrees on 30 June 2016 – 53 doctorates and 429 Master’s degrees – in the Callie Human Centre on the Bloemfontein Campus. On 29 June 2016, diplomas were awarded in the School of Financial Planning Law, as well as certificates and diplomas in education on the South Campus.

“You are smarter
than you think.
Smarter than other
people think you
are, and smarter
than the country
thinks you are.”

Rise above South African standards

According to Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, South Africans have become use to a low standard of human decency, entertainment, and academics. He encouraged the graduates to rise above it.

“You are smarter than you think. Smarter than other people think you are, and smarter than the country thinks you are.”

Make impact like honorary doctorates

Dr Khotso Mokhele, UFS Chancellor, asked the recipients of honorary doctorates, Prof Samoff, Max du Preez, Trevor Manuel and Dr Reuel Jethro Khoza, and of the two Chancellor’s medals, Antony Osler and Marguerite van der Merwe (née Osler), to face the graduates at the morning ceremony on 30 June 2016. “I challenge you to look at them and to emulate them,” he said. “May it transform you to be like them in 10, 15 or 20 years.”

Dr Mokhele thanks Prof Jansen as leader

Dr Mokhele made special mention of Prof Jansen, who will step down as Vice-Chancellor and Rector on 31 August 2016, as these were his last UFS graduations. He thanked Prof Jansen for his major contribution to transformation at the UFS. “You are not only a Vice-Chancellor, but also a project leader,” Dr Mokhele said.
