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.

UFS Library book launch programme fosters dialogue between students and authors

2017-03-30

The University of the Free State (UFS) Sasol Library has hosted a series of book launches since 2016, bringing to the Bloemfontein Campus various new and seasoned authors who share their stories with the campus audiences. The Launch Your Book at the Library Programme hosted two authors on 23 March 2017, Itumeleng Sekhu and Marcia Ramodike. Both authors spoke about their life-changing experiences and shared their heart-wrenching stories, filled with courage and hope.

“Libraries must take the lead in creating dialogue, expression of ideas and inculcating a culture of reading and writing. This programme was also established to bridge the gap and find ways to encourage students to read and write, by creating a platform where they can interact with authors and see that people who write books are ordinary people with real stories to tell,” said Marcus Maphile, Assistant Director: Library Marketing and Community Engagement.

Speaking about her book, Itumeleng Sekhu described her experiences from childhood and her life as a disabled person after being severely burnt in a fire accident in her home as a baby. She said: “I tried to commit suicide several times because I had lost hope. Eventually after failing to do so, I realised at some point that it was time for me to let my light shine through.” She wrote her book, titled What Do You See?, which has received substantial media coverage, to encourage others who live with painful experiences, disabilities and what she terms “internal wounds”, hoping that her experiences could help to heal them.

Marcia Ramodike’s book, An Empty Pride to a Full Price, paints a picture of her life as a youth grappling with adult issues. She describes her pain after her mother’s death, and her constant battle with the legacy of the difficult socio-economic conditions she grew up in. When students asked Ramodike what she thought the right time was to write a book, she responded, “today is the right time to write your story”.

The UFS Library has hosted 16 book launches since 2016, with the biggest being the launch of Zubeida Jaffer’s book Beauty of the Heart. The programme aims to provide access to information and to share and debate ideas in support of democracy and freedom of speech.
