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 of our academics contribute to a fascinating book

The planet has more species than ever before, but humans are responsible for the biggest mass extinction of all times. This is according to Prof. Jo van As, Head of the Department of Zoology and Entomology. He was speaking at the launch of the book The Story of Life & the Environment: An African Perspective.

The book was published by Random House Struik in July 2012 and is a sister publication of The Story of Earth & Life by Prof. Bruce Rubidge, which was published in 2005.

The Story of Life & the Environment: An African Perspective took five years to complete. Prof. Van As was the compiling author, with Prof. Johann du Preez, Head of Plant Sciences at our university, Prof. Leslie Brown of Unisa and Prof. Nico Smit of the North-West University as co-writers.

Prof. Van As said, “No other species has destroyed the earth as we have done. Biological diversity disappears at the rate of mass extinction. The effects of human activities on the biological diversity is bigger that the extinction of the dinosaurs.”

He, however, added that The Story of Life & the Environment: An African Perspective does not sketch a doomsday scenario. It has also a message of hope. Prof. Van As said it was good to see progress in conservation and care for the environment. Trans-frontier parks the size of some countries are a good example of work in this regard.

Mr Stephen Johnson, chairperson of the board of Random House Struik, said at the launch that the publishing house was proud to be associated with the impressive book. The publication will be a touchstone for thoughtful readers for a long time. It will also remain a general book for the public and learners on the topic. The content and design was done in such a way that the publication will be relevant to all audiences.

The Afrikaans version of the book, Die Verhaal van Lewe en die Omgewing, will be published soon.
