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.

National Arts Council opens doors for students in Drama and Theatre Arts

Thanks to bursaries from the National Arts Council (NAC), many students are finding it easier to study Drama and Theatre Arts, the discipline is able to offer more job opportunities, and it provides an opportunity to those who probably would never have had the chance. This is according to Prof Nico Luwes, Head of the Department of Drama and Theatre Arts at the University of the Free State (UFS).

This year, several students from the UFS, including 12 undergraduates and four postgraduates, are again beneficiaries of NAC bursaries to the value of roughly R206 000 – about R150 000 of which will be used for undergraduate studies and R56 000 for postgraduate studies. The UFS was awarded the same amount for undergraduate students in the previous year, but didn’t then receive NAC bursaries for postgraduate studies.

Good relationship with NAC over many years
The UFS has received NAC bursaries since 2005, and Prof Luwes says the university’s good relationship with the council runs over many years. “They are very happy with the feedback on our students’ achievements,” he says.

“Although Dramatic Arts is a matric subject, the provincial department of education does not support students with education bursaries for this subject. With bursaries from the National Arts Council, students can thus study to become theatre artists, and work as teachers for the Dramatic Arts in schools.”

Alumni stand out in entertainment industry
Prof Luwes says his department provides students the opportunity to do performances and practical exams in English, Afrikaans, and Sesotho. This is done to give all students an equal opportunity to excel. “In addition, several of our alumni have achieved success in the entertainment industry, and our staff members often feature in professional performances at arts festivals.”

Undergraduate students who were awarded NAC bursaries:
•   Jolene Swartz
•   Boitumelo Mohutsioa
•   René Lombard
•   Mandisa Wiso
•   Thapelo Mabona
•   Charlize Oberholster
•   Thembisile Baai
•   Naledi Maolusi
•   Mbuyiselo Nqodi
•   Vuyiswa Mxasa
